program interpreter for arm eabi is wrong

Terry Kemp4-16-2009 21:35 UTC

I can't seem to find the secret sauce that gives me program interpreter = ld-linux.so.3 for my arm eabi prgrams so I am having to symlink /lib/ld-linux.so.2 to /lib/ld-linux.so.3 on my gumstix.

It used to work for me with the FPC_ARMEL ifdef in tlinux.pas
{$ifdef arm}
{$ifdef FPC_ARMEL}
     defdynlinker:='/lib/ld-linux.so.3';
{$else FPC_ARMEL}
     defdynlinker:='/lib/ld-linux.so.2';
{$endif FPC_ARMEL}
{$endif arm}

but not it seems any more.
Any clues as to what is overriding this?

thanks

Terry

toolchain is..
arm-angstrom-linux-gnueabi-

fpc-svn arm eabi built with...

make clean crosszipinstall CPU_TARGET=arm CROSSOPT='-CaEABI -dFPC_ARMEL -dFPC_ABI_EABI -CfSOFT -gl -O-' FPC=ppcx64-2.2.2
cd ./utils/fppkg
make clean all CPU_TARGET=arm CROSSOPT='-CaEABI -dFPC_ARMEL -dFPC_ABI_EABI -CfSOFT -gl -O-' FPC=../../compiler/ppcrossarm cd ../../
make crosszipinstall CPU_TARGET=arm CROSSOPT='-CaEABI -dFPC_ARMEL -dFPC_ABI_EABI -CfSOFT -gl -O-' FPC=ppcx64-2.2.2

(I don't usually use the -CaEABI -dFPC_ABI_EABI and -FD options but I'm covering all bases here)

compile command...
ppcrossarm-2.3.1 -a -B -Xd -MObjFPC -darm231qt -dUSE_QT_44 -dQTOPIA -CfSOFT -dFPC_ARMEL -dFPC_ABI_EABI -O- -Fl~/bin/Qt-arm -CaEABI -FD/build/gumstix/gumstix-oe/tmp/cross/arm-angstrom-linux-gnueabi/bin -gl dbtest.lpr
