[fpc-pascal] Linking Problems while cross compiling for arm

[Hartmut Eilers]

Hallo List,

thanks for your first and fast response. According to the suggestions
from Marco and Jonas I try it this way:

ubuntu at 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

DeviceServer.pas(609,2) Error: Error while linking
DeviceServer.pas(609,2) Fatal: There were 1 errors compiling module, stopping

If I run the above command with strace I see:
access("/usr/local/lib/fpc/2.4.0/units/arm-linux/rtl/ucprt0.o", F_OK)
= 0

so I assume that the compiler is aware of compiling for a uclibc system.
therefor I tried to pass the lib path to the linker:

>From my point of view the -k"-L..." is the correct path and libdl is
located there.

Can anybody enlighten me in this ?
After one weekend fiddeling with all this I'm very confused.
Thanks for your help
