I am successfully cross-compiling stuff (although no LCL) from Linux32 to Linux64. I assume the other way around should also be possible. It looks like you are almost there, you only need to satisfy the library dependencies. Getting the cross compiler set up and running was easy, I did it from source, not using any apt-get at all to not compromise my system. It turned out that as and ld on Ubuntu 32 bit are already capable of working with 32 and 64 binaries, all that was needed are the correct command line switches, i found two small one-liner wrapper scripts for as and ld somewhere in the wiki. Then I got FPC working, I assume you have mastered this first step already. The next problem are the linker errors. My concrete library that I am cross compiling (its a libpurple plugin) depends on far less libraries than lcl but I still got a whole bunch of linker errors, then I did he following: I made a new empty folder /usr/lib64 (I guess you might want to make a folder /usr/lib32) and make sure it is on the library search path for ld, then I went through each of the errors one by one and searched which deb package (the libsomething and the corresponding libsomething-dev) would contain these libs on the target platform, downloaded the .deb and extracted them manually (NOT with dpkg!) and copied the libs (and the symlinks from the -dev packages) to my new lib folder, made sure all symlinks were working and tried to compile and link again and each time I added more needed libraries the errors got less until it finally succeeded. It looks like this is the only thing that is still missing and you are only a few hours away from success. -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
