[fpc-pascal] Cross-compiling from 64-bit Linux to 32-bit Linux
Hi I'm running Ubuntu 9.04 (64-bit) and have FPC 2.4.1 installed. I cross-compiled a 32-bit version of FPC as well. I'm not trying to compile my fpGUI based projects under my 64-bit system to 32-bit Linux executables. But I am getting the following linking errors. Does anybody know how to resolve this? What compatibility packages (*.deb) do I have to install so I can compile and link GUI applications. - Linking Bin/i386-linux/tutoradmin /usr/bin/ld: skipping incompatible /usr/bin/../lib/libdl.so when searching for -ldl /usr/bin/ld: skipping incompatible /usr/bin/../lib/libdl.a when searching for -ldl /usr/bin/ld: skipping incompatible /usr/bin/../lib/libpthread.so when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/bin/../lib/libpthread.a when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/bin/../lib/libX11.so when searching for -lX11 /usr/bin/ld: skipping incompatible /usr/bin/../lib/libX11.a when searching for -lX11 /usr/bin/ld: skipping incompatible /usr/lib/libX11.so when searching for -lX11 /usr/bin/ld: skipping incompatible /usr/lib/libX11.a when searching for -lX11 /usr/bin/ld: cannot find -lX11 tutoradmin.lpr(89,1) Error: Error while linking tutoradmin.lpr(89,1) Fatal: There were 1 errors compiling module, stopping Fatal: Compilation aborted - Regards, - Graeme - -- fpGUI Toolkit - a cross-platform GUI toolkit using Free Pascal http://opensoft.homeip.net/fpgui/ ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Install the ia32-libs package. also check if your fpc.cfg contain the following lines, I not remember if I add them: #ifdef cpui386 -Fl/usr/lib32 -Xd #endif Patrick ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Beware the path are not the same with Redhat! /usr/lib is 32bit and /usr/lib64 for 64bit.

It seems the linker can't find the libX11 library to link against. Your reply about 'locate crti.o' gave me an idea. I did the following... $ locate libX11.so /usr/lib/libX11.so /usr/lib/libX11.so.6 /usr/lib/libX11.so.6.2.0 /usr/lib32/libX11.so.6 <-- missing unversioned libX11.so /usr/lib32/libX11.so.6.2.0 I noticed the "unversioned" libX11.so is missing from the /usr/lib32/ directory. I manually added a symbolic link and it solved the linking -lX11 problem, but then prompted about -lXft. I did a another locate and it had the same problem. Added another "unversioned" symbolic for libXft.so and now my project successfully links!!! :-) Thanks for getting me onto the right track. What location in the wiki will be appropriate for such information, in case somebody else gets stuck with cross-compiling and a similar linking problem? I used packages.ubuntu.com to search for packages that contain libX11.so. I noticed that only from Ubuntu 9.04 (Jaunty) does the ia32-libs include the unversioned symbolic link. I made a mistake in my original post, I am actually running Ubuntu 8.04.2 (Hardy) 64-bit.
