Build failing on Solaris

[Karl Hanzel]

I've tried to google-up an answer but am not finding it, even tho i have
seen passing reference to what sounds like the same problem from others.

On a Solaris-8 machine i'm trying to build Python-2.3.2. Using gcc-3.2.
All seems to go pretty well for a while, but them i'm getting the
following:

--------------------
$ make
....
case $MAKEFLAGS in \
*-s*) CC='gcc' LDSHARED='gcc -shared' OPT='-DNDEBUG -g -O3 -Wall -Wstrict-prototypes' ./python -E ./setup.py -q build;; \
*) CC='gcc' LDSHARED='gcc -shared' OPT='-DNDEBUG -g -O3 -Wall -Wstrict-prototypes' ./python -E ./setup.py build;; \
esac
running build
running build_ext
Segmentation Fault - core dumped
gmake: *** [sharedmods] Error 139
--------------------

I've confirmed the seg fault is coming from

./python -E .setup.py build

'Utterly unsure how to proceed. Thanks for any/all help.

Certain versions of binutils do not correctly support dynamic linking on
Solaris, which gives rise to symptoms similar to the ones you are seeing. I
am pretty sure that binutils 2.13.2.1 works. To find out whether the
version on your machine works, you can execute the following shell script:

#! /bin/sh
mkdir /tmp/t.$$ || exit 3
cd /tmp/t.$$ || exit 3
cat >main.c <<'EOF'
#include <stdio.h>
#include <dlfcn.h>
int main(void)
{
void *handle, *sym;
char *error;
puts("calling dlopen");
handle = dlopen("./dyn.so", RTLD_NOW);
if (!handle) {
printf("%s\n", dlerror());
return 1;
}
puts("calling dlsym");
sym = dlsym(handle, "sym");
if ((error = dlerror()) != 0) {
printf("%s\n", error);
return 1;
}
puts("calling sym");
((void (*)(void))sym)( );
puts("done");
return 0;
}
EOF
cat >dyn.c <<'EOF'
#include <stdio.h>
void sym(void)
{
puts("in sym");
}
EOF
[ -n "$SHFLAGS" ] || SHFLAGS="-fPIC -shared"
[ -n "$CC" ] || CC=gcc
set -x
$CC $CFLAGS $SHFLAGS dyn.c -o dyn.so
$CC $CFLAGS main.c -o main -ldl
../main || exit $?
cd /tmp
rm -rf t.$$

Thanks, Andrew. As you suspected, your script generates the seg fault &
returns the same errant "139" observed during the build of Python. I'll
install an updated 'binutils' package and try again.
