Building gmp library for the iPhone-Update

[Pierre-Henri Jondot]

Hi,

Following some of the advice in http://latenitesoft.blogspot.com/2008/10/iphone-programming-tips-building-unix.html
I managed to get a bit further in the building of gmp. (At least I got  
past the configure step...)

I tried two configurations, one for iPhoneOS 2.2 (gcc 4.0.1)
and one targetting iPhone OS 3.0. (gcc 4.2.1)

In both cases, build fails with at the same spot (here for OS 3.0)  
with :

  /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple- 
darwin9-gcc-4.2.1 -c -DHAVE_CONFIG_H -I. -I. -I.. -D__GMP_WITHIN_GMP - 
I.. -DOPERATION_invert_limb -I/Developer/Platforms/iPhoneOS.platform/ 
Developer/SDKs/iPhoneOS3.0.sdk/usr/lib/gcc/arm-apple-darwin9/4.2.1/

include/ -I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/ 
iPhoneOS3.0.sdk/usr/include/ -pipe -no-cpp-precomp -isysroot / 
Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk  
tmp-invert_limb.s -o invert_limb.o
tmp-invert_limb.s:56:unsupported relocation on symbol invtab
tmp-invert_limb.s:56:FATAL:Internal error: incorrect fx_r_type (17)  
for fx_subsy != 0 in fix_to_relocation_info()
make[2]: *** [invert_limb.lo] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

Does it ring a bell ?

Regards,

Pierre-Henri
