  • How to use C to write a C compiler?

    - by israkir
    I am taking a compiler course this semester and we talked about this interesting thing in the class. Teacher used an example of p-code along with pascal to explain it. After google-ing a bit, I saw this phenomena is called self-hosting and naturally related to the first compilers. Ok, there is an interpreter which interprets the compiler source code written in its own language. But, there is still something missing in the explanations I found. I mean, there are some parts still looks mysterious (what about the interpreter? it is also a program, still need to be translated into machine code etc...) What I am asking you guys is that can you explain it as simple as possible or provide any online resource which you think that it explains this phenomena precisely..

  • user defined Copy ctor, and copy-ctors further down the chain - compiler bug ? programmers brainbug

    - by J.Colmsee
    Hi. i have a little problem, and I am not sure if it's a compiler bug, or stupidity on my side. I have this struct : struct BulletFXData { int time_next_fx_counter; int next_fx_steps; Particle particles[2];//this is the interesting one ParticleManager::ParticleId particle_id[2]; }; The member "Particle particles[2]" has a self-made kind of smart-ptr in it (resource-counted texture-class). this smart-pointer has a default constructor, that initializes to the ptr to 0 (but that is not important) I also have another struct, containing the BulletFXData struct : struct BulletFX { BulletFXData data; BulletFXRenderFunPtr render_fun_ptr; BulletFXUpdateFunPtr update_fun_ptr; BulletFXExplosionFunPtr explode_fun_ptr; BulletFXLifetimeOverFunPtr lifetime_over_fun_ptr; BulletFX( BulletFXData data, BulletFXRenderFunPtr render_fun_ptr, BulletFXUpdateFunPtr update_fun_ptr, BulletFXExplosionFunPtr explode_fun_ptr, BulletFXLifetimeOverFunPtr lifetime_over_fun_ptr) :data(data), render_fun_ptr(render_fun_ptr), update_fun_ptr(update_fun_ptr), explode_fun_ptr(explode_fun_ptr), lifetime_over_fun_ptr(lifetime_over_fun_ptr) { } /* //USER DEFINED copy-ctor. if it's defined things go crazy BulletFX(const BulletFX& rhs) :data(data),//this line of code seems to do a plain memory-copy without calling the right ctors render_fun_ptr(render_fun_ptr), update_fun_ptr(update_fun_ptr), explode_fun_ptr(explode_fun_ptr), lifetime_over_fun_ptr(lifetime_over_fun_ptr) { } */ }; If i use the user-defined copy-ctor my smart-pointer class goes crazy, and it seems that calling the CopyCtor / assignment operator aren't called as they should. So - does this all make sense ? it seems as if my own copy-ctor of struct BulletFX should do exactly what the compiler-generated would, but it seems to forget to call the right constructors down the chain. compiler bug ? me being stupid ? Sorry about the big code, some small example could have illustrated too. but often you guys ask for the real code, so well - here it is :D EDIT : more info : typedef ParticleId unsigned int; Particle has no user defined copyctor, but has a member of type : Particle { .... Resource<Texture> tex_res; ... } Resource is a smart-pointer class, and has all ctor's defined (also asignment operator) and it seems that Resource is copied bitwise. EDIT : henrik solved it... data(data) is stupid of course ! it should of course be rhs.data !!! sorry for huge amount of code, with a very little bug in it !!! (Guess you shouldn't code at 1 in the morning :D )

  • Make errors - can the gcc compiler warnings prevent a C file from being compiled into an object file

    - by Xolstice
    I'm trying to compile a wireless network card driver for my Linux box and I ran into a problem with the Make command. During the compilation process I normally see warnings on some of the C files that being are compiled; despite the warnings these files were still able to be compiled to an object file. When the Make process comes to a file called rtmp_wext.c however, the compiler generates a large number of warnings and then the whole Make process stops and returns an exit status of error 1, i.e. make: *** [rtmp_wext.o] Error 1. Usually I see an error with the C file for compilation to halt. This is the first time where it seems compiler warnings are preventing the file from being turned into an object file; is this possible or is something else the cause for the unsuccessful compilation?

  • JVM specification and Java compiler code useful for SCJP preparation ?

    - by BenoitParis
    I'm preparing the SCJP exam with the almost official study book ("SCJP Sun Certified Programmer for Java 6 Exam 310-065") I understand that Java programming is writting code that fulfills a certain high-level contract; So that Java can stay platform-independent. However, I have trouble understanding and remembering things when it comes to highly specific SCJP items (and they are numerous) The book stays high-level and does not provide examples of how one compiler would handle things. This is the same thing for runtime issues (JVM level): things are too much abstract for me. Rules often seems arbitrary and therefore, with no well defined purpose, are difficult to remember. Or maybe it's that sometimes I just don't get the underlying purpose. And here is the question: Would a JVM specification and/or some java compiler code help in preparing the SCJP? Have you had the need for such material or is the book sufficient enough? Also, please share the resources you used, apart from the book.

  • Convert HTACCESS mod_rewrite directives to nginx format?

    - by Chris
    I'm brand new to nginx and I am trying to convert the app I wrote over from Apache as I need the ability to serve a lot of clients at once without a lot of overhead! I'm getting the hang of setting up nginx and FastCGI PHP but I can't wrap my head around nginx's rewrite format just yet. I know you have to write some simple script that goes in the server {} block in the nginx config but I'm not yet familiar with the syntax. Could anyone with experience with both Apache and nginx help me convert this to nginx format? Thanks! # ------------------------------------------------------ # # Rewrite from canonical domain (remove www.) # # ------------------------------------------------------ # RewriteCond %{HTTP_HOST} ^www.domain.com RewriteRule (.*) http://domain.com/$1 [R=301,L] # ------------------------------------------------------ # # This redirects index.php to / # # ------------------------------------------------------ # RewriteCond %{THE_REQUEST} ^[A-Z]+\ /(index|index\.php)\ HTTP/ RewriteRule ^(index|index\.php)$ http://domain.com/ [R=301,L] # ------------------------------------------------------ # # This rewrites 'directories' to their PHP files, # # fixes trailing-slash issues, and redirects .php # # to 'directory' to avoid duplicate content. # # ------------------------------------------------------ # RewriteCond %{DOCUMENT_ROOT}/$1.php -f RewriteRule ^(.*)$ $1.php [L] RewriteCond %{DOCUMENT_ROOT}/$1.php -f RewriteRule ^(.*)/$ http://domain.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^[A-Z]+\ /[^.]+\.php\ HTTP/ RewriteCond %{DOCUMENT_ROOT}/$1.php -f RewriteRule ^([^.]+)\.php$ http://domain.com/$1 [R=301,L] # ------------------------------------------------------ # # If it wasn't redirected previously and is not # # a file on the server, rewrite to image generation # # ------------------------------------------------------ # RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^([a-z0-9_\-@#\ "'\+]+)/?([a-z0-9_\-]+)?(\.png|/)?$ generation/image.php?user=${escapemap:$1}&template=${escapemap:$2} [NC,L]

  • Apache + LDAP Auth: access to / failed, reason: require directives present and no Authoritative hand

    - by Karolis T.
    Can't solve this one, here's my .htaccess: AuthPAM_Enabled Off AuthType Basic AuthBasicProvider ldap AuthzLDAPAuthoritative on AuthName "MESSAGE" Require ldap-group cn=CHANGED, cn=CHANGED AuthLDAPURL "ldap://localhost/dc=CHANGED,dc=CHANGED?uid?sub?(objectClass=posixAccount)" AuthLDAPBindDN CHANGED AuthLDAPBindPassword CHANGED AuthLDAPGroupAttribute memberUid AuthLDAPURL is correct, BindDN and BindPassword are correct also (verified with ldapvi -D ..). Apache version: Apache/2.2.9 (Debian) The error message seems cryptic to me, I have AuthzLDAPAuthoritative on so where's the problem. EDIT: LDAP modules are loaded, the problem is not with them being missing. # ls /etc/apache2/mods-enabled/*ldap* /etc/apache2/mods-enabled/authnz_ldap.load /etc/apache2/mods-enabled/ldap.load EDIT2: Solved it by changing funky Require ldap-group cn=CHANGED, cn=CHANGED line with Require valid-user Since AuthzLDAPAuthoritative is on, no other auth methods will be used and valid-user requirement will auth via LDAP. (right? :/)

  • Any other preprocessor directives in VBScript/Classic ASP?

    - by Frank
    The only pre-process directive that I know about in VBScript / Classic ASP is the #include. I don't know if that is the official name but I'm basically looking for code that can execute code or other instructions before the general VBScript. Are there any other such directives in VBScript? Such as #If or something? I'd like to be able to conditionally include or exclude a certain include file.

  • What does the :compiler command do in Vim?

    - by Martín Fixman
    I recently found that there is a command in Vim called compiler. You can call it with any common compiler (for example, :compiler gcc, :compiler php, etc.), but it doesn't seem to have any immediate effect. I searched on the manpages but didn't find anything useful about what it actually does, nor does the Vim Wiki. Does anyone know what that command actually does?

  • How is it possible to write the compiler of a programming language with that language itself [closed]

    - by tugberk
    Possible Duplicate: How could the first C++ compiler be written in C++? You probably heard that Microsoft released a new language called TypeScript which is a the typed superset of JavaScript. The most interesting thing that makes me wonder is the fact that its compiler writen in TypeScript itself. Call me ignorant but I really couldn't figure out in my head how that is possible. This is just like chicken and egg problem in my head because there is no compiler to compile TypeScript's compiler in the first place. How is it possible to write a compiler of the compiler of a programming language with that language?

  • Remote server security: handling compiler tools

    - by Gonzolas
    Hello! I was wondering wether to remove compiler tools (gcc, make, ...) from a remote production server, mainly for security purposes. Background: The server runs a web application on Linux. Consider Apache jailed. Otherwise, only OpenSSHd faces the public network. Of course there is no compiler stuff within the jail, so this is about the actual OS outside of any jails. Here's my personal PRO/CON list (regarding removal) so far: PRO: I had been reading some suggestions to remove compiler tools in order inhibit custom building of trojans etc. from within the host if an attacker attains unpriviliged user permissions. CON: I can't live without Perl/Python and a trojan/whatever could be written in a scripting language like that, anyway, so why bother about removing gcc et al. at all. There is a need to build new Linux kernels as well as some security tools from source directly on the server, because the server runs in 64-bits mode and (to my understanding) I can't (cross-)compile locally/elsewhere due to lack of another 64-bits hardware system. OK, so here are my questions for you: (a) Is my PRO/CON assessment correct? (b) Do you know of other PROs / CONs to removing all compiler tools? Do they weigh in more? (c) Which binaries should I consider dangerous if the given PRO statement holds? Only gcc, or also make, or what else? Should I remove the enitre software packages them come with? (d) Is it OK to just move those binaries to a root-only accessible directory when they are not needed? Or is there a gain in security if I "scp them in" every time? Thank you!

  • Adding gcc 4.9 as a compiler option in Xcode

    - by user2129150
    I asked this question on StackOverflow, but it's pretty much stagnant. Sorry if this is considered a repost/double-post. I just installed gcc 4.9 (with C11 support), and want to add it to Xcode 4.6.3's build options as a compiler option. I ran make and make install, and the packages are all there (under /usr/bin/gcc. Running gcc --version confirms that gcc 4.9 is installed rather than an older version. When I go into an existing Xcode project's build settings, the only compiler options available are Apple LLVM compiler 4.2 LLVM GCC 4.2 Other... Clearly, GCC 4.9 would have to be added using the "Other..." option, although I'm not sure how. I've tried inputting the path to gcc (/usr/bin/gcc), although the default value for other isn't a path at all: com.apple.compilers.llvmgcc42. I've also tried following the instructions from the answer to this question as well, but the machine I'm on doesn't have the /Developer directory at all, since I believe Apple integrated the developer tools that required (and created) this directory into Xcode. How do I add gcc 4.9 as a compiler option in Xcode?

  • Can I make the compiler and the CLR ignore non implemented interfaces on my types?

    - by Thiado de Arruda
    I would like to define a type implementing a certain interface, however I would only implement it in a proxy at runtime. I can see two obstacles in this scenario : 1-Make the compiler ignore non implemented interfaces. 2-Make the CLR ignore(or at least delay) the TypeLoadException with the following description : "Method SOMEMETHOD in type SOMETYPE from assembly SOMEASSEMBLY does not have an implementation." Is something like this possible?

  • Make compiler copy characters using movsd

    - by Suma
    I would like to copy a relatively short sequence of memory (less than 1 KB, typically 2-200 bytes) in a time critical function. The best code for this on CPU side seems to be rep movsd. However I somehow cannot make my compiler to generate this code. I hoped (and I vaguely remember seeing so) using memcpy would do this using compiler built-in instrinsic, but based on disassembly and debugging it seems compiler is using call to memcpy/memmove library implementation instead. I also hoped the compiler might be smart enough to recognize following loop and use rep movsd on its own, but it seems it does not. char *dst; const char *src; // ... for (int r=size; --r>=0; ) *dst++ = *src++; Is there some way to make the Visual Studio compiler to generate rep movsd sequence other than using inline assembly?

  • Visual Studio: Add necessary using directives with macro

    - by Kiril
    Hello guys, I am trying to do the following. Imagine you are reading some LINQ article and you decide to copy/paste some code from the article to a newly created project. In most cases, if you directly compile you will probably get an error for missing a using directives or assembly reference. I am trying to optimize the process where I have to go each keyword, click on it with the mouse and hit Shift + Alt + F10 to add the using directive. I know that it is not that much pain, but for the sake of optimization, is it possible and at what cost? Best Regards, Kiril

  • Why will this code compile using ifort compiler and not when using gfortran compiler? Help!

    - by CuriousCompiler
    I'm rewriting some code to make a program compile with the gfortran compiler as opposed to ifort compiler I usually use. The code follows: _Subroutine SlideBits (WORD, BITS, ADDR) Implicit None Integer(4) WORD Integer(4) BITS Integer(4) ADDR Integer(4) ADDR1 ADDR1 = 32 - ADDR WORD = (WORD .And. (.Not.ISHFT(1,ADDR1))) .Or. ISHFT(BITS,ADDR1) End_ When I compile the above code using the gfortran compiler, I recieve this error: WORD = (WORD .And. (.Not.ISHFT(1,ADDR1))) .Or. ISHFT(BITS,ADDR1) Error: Operand of .NOT. operator at (1) is INTEGER(4) All three of the variables coming into the subroutine are integers. I've looked around a bit and the gfortran wiki states that the gfortran compiler should be able to handle logical statments being applied to integer values. Several other sites I've visited either quote from the gnu wiki or agree with it. This is the first time I've seen this error as the Intel Fortran compiler (ifort) I normally use compiles cleanly.

  • Question on preprocessor directives

    - by dotnetdev
    If I use proprocessor directives to define which code an OS will run, like so: #if winXP // Compiling for Windows XP platformName = "Microsoft Windows XP"; #elif win2000 // Compiling for Windows 2000 platformName = "Microsoft Windows 2000"; #elif win7 // Compiling for Windows 7 platformName = "Microsoft Windows 7"; #else // Unknown platform specified platformName = "Unknown"; How does the system pick up which OS is being used? This is an example from the book Visual C# 2010 Recipes, where the author says that the platformName variable (declaration ommitted), wil equal the OS above. Thanks
