compilation errors on iPhone

I'm trying to build libgcrypt so that I can build vpnc on the iphone,
but I'm running into a compilation/assembly error that I've not been
able to solve.

/usr/local/arm-apple-darwin/bin/gcc -DHAVE_CONFIG_H -I. -I. -I..
-I../src -I/usr/local/arm-apple-darwin/include -g -O2 -Wall -MT
mpih-div.lo -MD -MP -MF .deps/mpih-div.Tpo -c mpih-div.c -fno-common
-DPIC -o .libs/mpih-div.o
Bad $ operand number in inline asm string: '${:@} Inlined umul_ppmm
umull ${1:r}, ${0:r}, ${2:r}, ${3:r}'
make[2]: *** [mpih-div.lo] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

The iPhone is an arm processor, though I wasn't able to figure out how
mpih-dev.c got the correct #defines to figure out which assembly macro
was actually being called...

anyhow, I was hoping to get some suggestions on workarounds or
solutions so I can get this built.

config.log : http://eludicate.com/~bolen/tmp/gcrypt_iphone/config.log

thanks,

B

My guess is that the problem is in mpi/longlong.h

mpi/config.links is the script run from configure which figures out
these details and creates some macros.

Salam-Shalom,

iPhone toolchain's as doesn't like that % stuff in registers (sheesh, that's
apple-patched *gnu as*).

It does compile if rewritten this way:
__asm__ ( \
"umull r1, r0, r2, r3" \
: "=&r" ((USItype)(xh)), \
"=r" ((USItype)(xl)) \
: "r" ((USItype)(a)), \
"r" ((USItype)(b)) \
: "r0", "r1")

but later fails on:

/home/farcaller/develop/iphone/rootfs/home/farcaller/develop/iphone/toolchain/
lib/gcc/arm-apple-darwin/4.0.1/libgcc.a(_udivsi3.o)
has external relocation entries in non-writable section (__TEXT,__text) for
symbols:
___div0
collect2: ld returned 1 exit status

Have you tried building with ./configure --disable-asm?
