I am able to compile FPC 2.6.1 (rev 22778) under Ubuntu 11.04 32 bits.
However cross compiling to win32 fails with the error: /usr/bin/ld:
cannot find -lgcc

I was able to cross compile successfully about 2 weeks ago.

The relevant part of the log:

What could have gone wrong?

There were changes merged. I wonder however how a crosscompile to win32 can
reach "fastcgi" still being target linux.

Could you post your build cmdline please?

The build command line (part of a script) is:
${MAKE} clean all LIBDIR=${BASELIBDIR}/${MCPU}-${MOS} CROSSBINDIR=${CROSSTOOLSROOT}bin OS_TARGET=${OS} CPU_TARGET=${CPU} BINUTILSPREFIX=${MCPU}-${MOS}- OPT="-Xd -Xt ${EXTRAOPT}" 


Upon closer inspection of the log (relevant portions in bold):
- Some make code is seeping into the command line
- fastcgi is being compiled using ppc and not ppcross386.

I can attach the whole log if needed.
