Comment(by drkirkby):
The method used to determine the target in {{{spkg-install}}} seems crazy
to me. First it tries using the the target {{{linux}}}, which
specifically forces a 32-bit build, with the {{{-m32}}} flag.
To me at least, on {{{sage.math}}}, I can compile with {{{-m32}}} and
create a 32-bit binary:
{{{
kir...@sage:~$ cat test.c
#include <stdio.h>
int main() {
printf("ddd");
}
kir...@sage:~$ gcc test.c
kir...@sage:~$ file a.out
a.out: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), for GNU/Linux
2.6.8, dynamically linked (uses shared libs), not stripped
kir...@sage:~$ gcc -m32 test.c
kir...@sage:~$ file a.out
a.out: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for
GNU/Linux 2.6.8, dynamically linked (uses shared libs), not stripped
}}}
So I would expect this to build 32-bit in most cases on Linux.
Only if the 32-bit build fails does it try a 64-bit build!!
Note for AIX and HP-UX, I did not bother with any such flags, but just let
it read CFLAGS, where one could add {{{-m64}}} or whatever flag one needs.
