Hallo List, I try to crosscompile one of my projects to the arm based USB9263 from Calao Systems (http://www.calao-systems.com/articles.php?lng=en&pg=5932)
I get the following linking error: ubu...@kubuntu904:~/OpenLabTools/DeviceServer$ /usr/local/bin/ppcrossarm -CfFPA -dUSB92 -CaARMEB -CpARMV5 -darm -dFPC_ARMEL -gl -Fu../webserver -Fu../PhysMach -Fu../divLibs/pwu-1.6.0.2-src/main/ -FL/usr/xtools/arm-unknown-linux-uclibc/arm-unknown-linux-uclibc/lib/ld-uClibc.so.0 -Fl/usr/local/xtools/arm-unknown-linux-uclibc/arm-unknown-linux-uclibc/lib/ -XParm-unknown-linux-uclibc- -Xd -Xr/usr/local/xtools/arm-unknown-linux-uclibc/ DeviceServer.pas Free Pascal Compiler version 2.4.0rc1 [2009/12/07] for arm Copyright (c) 1993-2009 by Florian Klaempfl Target OS: Linux for ARM Compiling DeviceServer.pas DeviceServer.pas(538,10) Warning: Function result does not seem to be set Assembling deviceserver Linking DeviceServer /usr/local/lib/fpc/2.4.0/units/arm-linux/rtl/cprt0.o: In function `_start': (.text+0x4c): undefined reference to `__libc_start_main' /usr/local/lib/fpc/2.4.0/units/arm-linux/rtl/cprt0.o: In function `_haltproc_eabi': (.text+0x88): undefined reference to `_fini' /usr/local/lib/fpc/2.4.0/units/arm-linux/rtl/cprt0.o: In function `_haltproc_eabi': (.text+0x90): undefined reference to `_init' DeviceServer.pas(609,2) Error: Error while linking DeviceServer.pas(609,2) Fatal: There were 1 errors compiling module, stopping Fatal: Compilation aborted I have built my own crosscompiler with fpc 2.2.2. Here are the steps I did: + download the toolchain from http://free-electrons.com/labs/tools/arm-unknown-linux-uclibc-gcc-4.3.2.tar.bz2 and uncompress it as root in /. Then, add the cross-compiler directory to the PATH export PATH=/usr/local/xtools/armunknownlinux-uclibcgnueabi/bin:$PATH + download a recent version of fpc svn checkout http://svn.freepascal.org/svn/fpc/tags/release_2_4_0_rc1 ./fpc240 + compile the compiler patch sdl mixer to avoid error, so no sdl lib is included cd ./fpc240 vi packages/sdl/src/sdl_mixer.pas change lines starting at 450 {$IFNDEF DARWIN} 5 : ( mp3 : PSMPEG ); {$ENDIF} with these lines, the sdl lib is removed ! {$IFNDEF DARWIN} {$IFNDEF no_smpeg} 5 : ( mp3 : PSMPEG ); {$ENDIF} {$ENDIF} make clean make crosszipinstall CPU_TARGET=arm CROSSOPT='-CfFPA -dUSB92 -darm -dno_smpeg -dFPC_ARMEL -O- -gl' CROSSBINDIR=/usr/local/xtools/arm-unknown-linux-uclibc/bin/ BINUTILSPREFIX=arm-unknown-linux-uclibc- + Installation of the binaries cd /usr/local/ tar -xzvf /home/ubuntu/fpc240/fpc-2.4.0rc1.arm-linux.tar.gz cd /usr/local/bin ln -s /usr/local/lib/fpc/2.4.0/ppcrossarm ppcrossarm Compiling programs: /usr/local/bin/ppcrossarm -CfFPA -dUSB92 -CaARMEB -CpARMV5 -darm -dFPC_ARMEL -gl -Fu../webserver -Fu../PhysMach -Fu../divLibs/pwu-1.6.0.2-src/main/ -FL/usr/xtools/arm-unknown-linux-uclibc/arm-unknown-linux-uclibc/lib/ld-uClibc.so.0 -Fl/usr/local/xtools/arm-unknown-linux-uclibc/arm-unknown-linux-uclibc/lib/ -XParm-unknown-linux-uclibc- -Xd -Xr/usr/local/xtools/arm-unknown-linux-uclibc/ DeviceServer.pas Can anybody give me hints what to do or check what I did wrong. Especially the steps building the crosscompiler. I also tried to use the -k ... with sys-root but the the linker complains that he couldn't find the dl lib. I guess I have something wrong with the pathes of the -F* parameters. ubu...@kubuntu904:~/OpenLabTools/DeviceServer$ /usr/local/bin/ppcrossarm -CfFPA -dUSB92 -CaARMEB -CpARMV5 -darm -dFPC_ARMEL -gl -Fu../webserver -Fu../PhysMach -Fu../divLibs/pwu-1.6.0.2-src/main/ -FL/usr/xtools/arm-unknown-linux-uclibc/arm-unknown-linux-uclibc/lib/ld-uClibc.so.0 -Fl/lib/ -XParm-unknown-linux-uclibc- -Xd -Xr/usr/local/xtools/arm-unknown-linux-uclibc/ -Fi /usr/local/xtools/arm-unknown-linux-uclibc/arm-unknown-linux-uclibc/include/c++/4.3.2/ -k"--sysroot=/usr/local/xtools/arm-unknown-linux-uclibc/arm-unknown-linux-uclibc/include/c++/4.3.2/sys-root/" DeviceServer.pas Warning: Only one source file supported, changing source file to compile from "/usr/local/xtools/arm-unknown-linux-uclibc/arm-unknown-linux-uclibc/include/c++/4.3.2/" into "DeviceServer.pas" Free Pascal Compiler version 2.4.0rc1 [2009/12/07] for arm Copyright (c) 1993-2009 by Florian Klaempfl Target OS: Linux for ARM Compiling DeviceServer.pas DeviceServer.pas(538,10) Warning: Function result does not seem to be set Assembling deviceserver Linking DeviceServer /usr/local/xtools/arm-unknown-linux-uclibc/bin/arm-unknown-linux-uclibc-ld: cannot find -ldl DeviceServer.pas(609,2) Error: Error while linking DeviceServer.pas(609,2) Fatal: There were 1 errors compiling module, stopping Fatal: Compilation aborted Thanks for your help regards Hartmut _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
