Things will break if you try and link with C libraries but building the compiler itself with softfloat options should work. If you want patches for hardfloat with 2.6.2 you can find them at https://code.google.com/p/bollin/source/browse/#svn%2Ffpc%2Ftrunk%2Fdebian%2Fpatches the hardfloat releated patches are armhf.diff armhf-linker-path.diff armhf-build-with-2.6.0.diff (only needed if bootstrapping with 2.6.0) and regenerate_messages.diff Once the patches are applied use -dFPC_ARMHF instead of -dFPC_ARMEL to get a hardlfoat build.

[fpc-devel] fpc 2.6.2 gives AV on arm
Hi all, I've cross-compiled a ppcarm, and now I try to use that compiler on qemu to build fpc (2.6.2). But the compiler crashes on compiling the system-unit. But with trunk (2.7.1) this all works. Thing is that I'm trying to get fpc 2.6.2 working on the new arm-target of Fedora (armv7, hardware float, little endian). Maybe someone knows in which revision this could have been fixed, so that I can apply that fix to 2.6.2 on Fedora?
