• How can I compile GCC as a static binary?

  - by CaCl

  How can I compile the GCC Compiler so that I can pull the entire thing over to another system and use the program? I don't mind pulling in other files as well, but is there a way to gather all the required system libs as well? The OS and Arch will remain constant across the different systems, but one may contain Slackware where the other contains Debian.

• Using sphinx to create context sensitive html help

  - by bluebill

  Hi all, I am currently using AsciiDoc (http://www.methods.co.nz/asciidoc/) for documenting my software projects because it supports pdf and html help generation. I am currently running it through cygwin so that the a2x tool chain functions properly. This works well for me but is a pain to setup on other windows computers. I have been looking for alternative methods and recently revisited Sphinx. Noticing that it now produces html help files I gave it a try and it seems to work well in the small tests I performed. My question is, is there a way to specify map id's for context sensitive help in the text so that my windows programs can call the proper help api and the file is launched and opened to the desired location? In AsciiDoc I am using "pass::[]". By using these constructs a context.h and alias.h are generated along with the other html help files (context sensitive help information).

• The usage of Cassandra's internal keyspace "system"

  - by knorv

  The default Cassandra systems keyspace system is present in all Cassandra installations. Judging from the output of the describe keyspace command the keyspace it is used partly for "persistent metadata for the local node" (LocationInfo) and partly for "hinted handoff data". What persistent metadata for the local node is stored in system/LocationInfo? What is the definition of hinted handoff in Cassandra terminology? What hinted handoff data is stored in the system keyspace?

• (iPhone) Instruments can't "Attach to Process"

  - by AlexLive

  Actually, I'm using a second generation Ipod Touch. What I'm trying to do is to debug my app on XCode and look for any memory leaks on Instruments at the same time. Is it even possible? Because the "Attach to Process" submenu lists when my app is running (or debugging in this case) but all the items inside this menu are disabled. All I can do is start the app from Instruments but later I come across some bug and I want to see the variables and properties affected. I'm also new to Instruments. Please, could someone give me any advice? Help would be greatly appreciated!

• NHibernate Unique Constraint on Name and Parent Object fails because NH inserts Null

  - by James

  Hi, I have an object as follows Public Class Bin Public Property Id As Integer Public Property Name As String Public Property Store As Store End Class Public Class Store Public Property Id As Integer Public Property Bins As IEnumerable(Of Bin) End Class I have a unique constraint in the database on Bin.Name and BinStoreID to ensure unique names within stores. However, when NHibernate persists the store, it first inserts the Bin records with a null StoreID before performing an update later to set the correct StoreID. This violates the Unique Key If I persist two stores with a Bin of the same name because The Name columns are the same and the StoreID is null for both. Is there something I can add to the mapping to ensure that the correct StoreID is included in the INSERT rather than performing an update later? We are using HiLo identity generation so we are not relying on DB generated identity columns Thanks James

• Semantic Diff Utilities

  - by rubancache

  I'm trying to find some good examples of semantic diff/merge utilities. The traditional paradigm of comparing source code files works by comparing lines and characters.. but are there any utilities out there (for any language) that actually consider the structure of code when comparing files? For example, existing diff programs will report "difference found at character 2 of line 125. File x contains v-o-i-d, where file y contains b-o-o-l". A specialized tool should be able to report "Return type of method doSomething() changed from void to bool". I would argue that this type of semantic information is actually what the user is looking for when comparing code, and should be the goal of next-generation progamming tools. Are there any examples of this in available tools?

• Does another version control system has a clearcase like filesystem access to file versions?

  - by Vijay

  In clearcase If I am working on some file X and want to also see its previous version(say version 5) it is available as X@@/main/5. Is something similar available with other (preferably free) version control systems? HG has hg cat and hg co. but they still do not come close to clearcase's feature above... Regards Vijay

• Changing Name Associated With Past Commits In Mercurial

  - by Sean M

  A friend recently had the occasion for a legal name change, which made me wonder about how to cope with that in a development environment, especially in regards to source control. Their legal name changed, so naturally their login name and associated identity stuff changed. If they were a team member of mine, I'd like to change the record of their past commits to the project to be consistent with their new name. Is that possible in Mercurial? In other version control systems?

• My Excel template is corrupted

  - by Prasanna

  I am using an Excel template (2003) for report generation. The workbook is of 4 sheets. The original template file works fine. But when I change the template (just remove a single static char), the report is getting generated but with some junk format. When I try opening the Excel file, I get this message: The following is a list of repairs: Damage to the file was so extensive that repairs were not possible. Excel attempted to recover your formulas and values, but some data may have been lost or corrupted. Please advise.

• 404 Error using Flash Builder 4 BlazeDS wizard

  - by codeflayer

  Hello again Stackoverflow! My issue this time around is trying to use the new DCD BlazeDS wizard in Flash Builder 4. If I set my project up as a combined Java/Flex app I am unable to connect to the RDS servlet using the wizard. I get a 404 error every time. I'm certain the service is set up correctly since my app can access the exposed java classes and BlazeMonster can see the exposed services. Is anyone else having this issue and if so has anyone found a work-around? I'd very much like to use the code generation features of the wizard for my project. Thanks as always, Codeflayer

• Rails: Convert HTML to PDF?

  - by rip747

  What is the best and easiest way of taking HTML and converting it into a PDF, similar to use CFDOCUMENT on ColdFusion? UPDATE: I really appreciate all the comments and suggestions that people have given so far, however I feel that people leaving their answers are missing the point. 1) the solution has to be free or open sourced. one person suggested using pricexml and the other pd4ml. both of these solutions costs money (pricexml costing an arm and a leg) which i'm not about the fork over. 2) they must be able to take in html (either from a file, url or a string variable) and then produce the pdf. libraries like prawn, rprf, rtex are produced using their own methods and not taking in html. please don't think i'm ungrateful for the suggestions, it's just that pdf generation seems like a really problem for people like me who use ColdFusion but want to convert to Rails.

• Basic concepts in file system implementation

  - by darkie15

  I am a unclear about file system implementation. Specifically (Operating Systems - Tannenbaum (Edition 3), Page 275) states "The first word of each block is used as a pointer to the next one. The rest of block is data". Can anyone please explain to me the hierarchy of the division here? Like, each disk partition contains blocks, blocks contain words, and so on...

• JXMapViewer change orientation to Heading Up

  - by Charlie

  I am trying to use JXMapViewer (from swingx-ws) with Open Street Maps. I was wondering if it would be possible to display the map tiles in the JXMapViewer based on heading up, rather than on North up. For example, the normal car GPS navigation systems let you do that. I've looked through the documentation and there doesn't seem to be a straightforward way to do this. Is there something else that accomplish this, besides JXMapViewer?

• how can I share a project-specific configuration between Aquamacs and gnu-emacs

  - by Arthur Ulfeldt

  I have a .emacs.d directory shared (via git) with branches for various projects and Aquamacs seems to be ignoring it completely. All the other development systems work very well with this system so I would prefer to keep it if it can be made to work with Aquamacs.

• How do I write a std::codecvt facet?

  - by Billy ONeal

  How do I write a std::codecvt facet? I'd like to write ones that go from UTF-16 to UTF-8, which go from UTF-16 to the systems current code page (windows, so CP_ACP), and to the system's OEM codepage (windows, so CP_OEM). Cross-platform is preferred, but MSVC on Windows is fine too. Are there any kinds of tutorials or anything of that nature on how to correctly use this class?

• Phantom updates due to decimal precision on calculated properties

  - by Jamie Ide

  This article describes my problem. I have several properties that are calculated. These are typed as decimal(9,2) in SQL Server and decimal in my C# classes. An example of the problem is: Object is loaded with a property value of 14.9 A calculation is performed and the property value is changed to 14.90393 When the session is flushed, NHibernate issues an update because the property is dirty Since the database field is decimal (9,2) the stored value doesn't change Basically a phantom update is issued every time this object is loaded. I don't want to truncate the calculations in my business objects because that tightly couples them to the database and I don't want to lose the precision in other calculations. I tried setting scale and precision or CustomType("Decimal(9,2)") in the mapping file but this appears to only affect schema generation. My only reasonable option appears to be creating an IUserType implementation to handle this. Is there a better solution?

• Robust unit-testing of HTML in PHP

  - by asbja

  I'm adding unit-tests to an older PHP codebase at work. I will be testing and then rewriting a lot of HTML generation code and currently I'm just testing if the generated strings are identical to the expected string, like so: (using PHPUnit) public function testConntype_select() { $this->assertEquals( '<select><option value="blabla">Some text</option></select>', conntype_select(1); // A value from the test dataset. ); } This way has the downside that attribute ordering, whitespace and a lot of other irrelevant details are tested as well. I'm wondering if there are any better ways to do this. For example if there are any good and easy ways to compare the generated DOM trees. I found very similar questions for ruby, but couldn't find anything for PHP.

• is there a way to create an item template (t4) installer like the POCO generator?

  - by bryanjonker

  Subject says it all. I want to modify the POCO generation adapter (http://code.msdn.microsoft.com/EFPocoAdapter) to generate my own code. I have the .tt adapters done, but I want to be able to distribute this to coworkers, so they right-click on the model, choose "Generate Code", and my t4 templates appear in the options along with the other choices. Is there an easy way to do this? I found some articles at http://msdn.microsoft.com/en-us/library/tsyyf0yh(VS.80).aspx but it was focused on generic templates, and I'm looking for specifically model templates.
