I use autoconf and when the target is mingw I was using the -mno-cygwin flag. This has been removed so I'm trying to using the mingw tool chain. The problem is the linker isn't finding my libraries
/bin/sh ../../../libtool --tag=CXX --mode=link mingw32-g++ -g -Wall -pedantic -DNOMINMAX -D_REENTRANT -DWIN32 -I /usr/local/include/w32api -L/usr/local/lib/w32api -o testRandom.exe testRandom.o -L../../../lib/Random -lRandom
libtool: link: mingw32-g++ -g -Wall -pedantic -DNOMINMAX -D_REENTRANT -DWIN32 -I /usr/local/include/w32api -o .libs/testRandom.exe testRandom.o -L/usr/local/lib/w32api -L/home/Tam/src/3DS_Games/lib/Random -lRandom
D:\cygwin\opt\MinGW\bin\..\lib\gcc\mingw32\3.4.5\..\..\..\..\mingw32\bin\ld.exe: cannot find -lRandom
To link this from the command line using the mingw linker the -L
path needs the drive letter i.e
mingw32-ld testRandom.o -LD:/home/Tam/src/3DS_Games/lib/Random -lRandom
works. The -L
path is generated from the makefile.am
's which have
LDADD = -L$(top_builddir)/lib/Random -lRandom
However I can't find how to set top_builddir
to a relative path or to start it with the drive letter (my autoconf skills are weak).
As a tempoary "solution" I have removed the use of libtool. I could hack a $(DRIVE_LETTER)
infront of every -L option, but I'd like to find something better.
