Mailing List Archive: Error Compiling GNUPGP-0.9.5 under AIX 4.1.5

Maybe somebody can help:

I tried to compile the current version on an AIX-4.1.5 ( I know it is an
old version, but I still have to use it).
I build myself a late version of the gcc compiler using egcs-1.1.2 and it
build quite a lot of packages fine.
When applying it to the gnupgp package I get the following error.
Any idea?

make
make all-recursive
Making all in intl
Target "all" is up to date.
Making all in zlib
Target "all" is up to date.
Making all in util
Target "all" is up to date.
Making all in mpi
gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include -g -O2 -Wall
-Wcast-align -Wshadow -Wstrict-prototypes -c mpih-div.c
mpih-div.c: In function `mpihelp_mod_1':
mpih-div.c:86: warning: implicit declaration of function `__udiv_w_sdiv'
mpih-div.c:189: fixed or forbidden register 64 (mq) was spilled for class
MQ_REGS.
This may be due to a compiler bug or to impossible asm
statements or clauses.
make: The error code from the last command is 1.

Stop.

Stop.

Any help appreciated,

Yes. ;-)

Gcc has a bug with ASM statements which cause to compile wrongly
defined ASM statements correctly. However, in egcs this bug isn't anymore
but most ASM statements in existing programms are not correct so egcs will
fail to compile them.
I'm not sure if the ASM statements in gnupg are fixed or not. But I think
they aren't which will result in this problems. I don't know much about
this issue but I think the problem domain is called `register clobbing' or
like.

As a solution you may try to use `--disable-asm' when you configure gnupg.
I don't know if this help.
