I have built a Win32 ppcrossarm.exe (2.20) compiler. The compiler works ok. The output from the Linux and the Win32 compiler when I use the -sh directive is exactly the same. The downside is I have some problems finding a Win32 linker that I can use.
If I compile a Hallow World program, it works ok, but when I try to compile a program that uses uLibc, the Win32 linker and the Linux linker dos not do exactly the same. When I run the output from the Win32 linker on my arm platform it stops with Segmentation fault The output from the Linux linker runs ok If I look in the map file the only difference I can see is (see at the end of this mail) Linux: 0x000080d4 . = (0x8000 + SIZEOF_HEADERS) Win32: 0x00008000 . = 0x8000 I have several versions of Win32 linkers (215,216,217) and Linux linkers (215,216,217,218). I have also seen this problem with a Linux linker (217) One of the Win32 linkers I have used if from ftp://ftp.freepascal.org/pub/fpc/contrib/cross/mingw/binutils-2.15.94-win32- arm-linux.zip Has anyone got a hint where to go from here.
