[fpc-devel] Building cross-compiler for arm-linux on win32

[Nikolai Zhubr]

Hi all,

Ok, apparently the binutils-2.15.94-win32-arm-linux.zip (provided on the 
fpc website) is somewhat outdated to be really usable for arm target.
Retrying with (self-built) binutils-2.28 apparently solves the previous 
problem but now I have another: ld yells something about VFP instructions:

T:/_tmp/fpcbuild-3.0.4/fpcsrc/compiler/ppcrossarm.exe -Tlinux -Parm 
-XParm-linux- -Xr -Ur -Xs -O2 -n -Fuarm -Fusystems 
-FuT:/_tmp/fpcbuild-3.0.4/fpcsrc/rtl/units/arm-linux -Fiarm -FE. 
-FUarm/units/arm-linux -dRELEASE -darm -dGDB -dBROWSERLOG -Sew    -darm 
-dGDB -dBROWSERLOG  -Sew pp.pas
C:\FPC\3.0.4\bin\i386-Win32\arm-linux-ld.exe: warning: .\link.res 
contains output sections; did you forget -T?

..... [lots of similar lines follow]

Any ideas?

Thank you!
