[fpc-pascal] ppcrossarm 220

[Carsten Bager]

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.

Regards

Carsten
