#26 SEGFAULT under Solaris

[Phillip Steinbachs]

I've compiled cpu 1.4.3 with openldap 2.1.25 and gcc
3.3.2, under Solaris 9 for Sparc. The compile is fine,
but trying to run cpu with any arguments yields an
immediate segfault.

For example:

# gdb
(gdb) set args useradd newuser
(gdb) exec-file /local/sbin/cpu
(gdb) run

Starting program: /local/sbin/cpu useradd newuser

Program received signal SIGSEGV, Segmentation fault.

763 globalLdap->dn = buildDn ((operation > 2) ?
GROUPADD : USERADD,

I thought the latest CVS might fix it, but it doesn't.
The same problem occurs.

Unfortunately I do not have access to a Solaris 9 machine
and the sourceforge compile farm is always down. Is there a
possibility that I could get an account on a Solaris 9
machine for a few days? If so, contact me at
bmatheny@purdue.edu. Someone did the same with FreeBSD and I
managed to get it working in a day.

Seems like I have the same problem under Irix 6.5.19m. gcc 3.3.

Running it in gdb seems to show that when
plugins/ldap/ldap.c:CPU_init() calls parseCommand(), it
really wants plugins/ldap/commandline.c:parseCommand() in
libcpu_ldap.so. Instead, it got main/cpu.c:parseCommand(),
so the globalLdap->dn does not exist.

Cheers,

OK. Here's what I did to make it work for me:

Edit configure file, I looked for the $archive_cmds
definition for Irix,
I then insert ${wl}-Bsymbolic before ${wl}-set_version.
This is for using gcc to link, which I presume it will pass
-Bsymbolic to the native Irix ld.

Anyway, it seems like different OSes behave differently when
searching for symbols from shared libraries using the
"default" linker option.

Irix: Symbols referenced from shared library is searched
for in the main executable first, then the shared library.
Solaris: Looks like Irix style.
hpux: Won't even search in main executable unless explicitly
told to do so.
AIX: Looks into shared library first.
Linux: Dunno, the debian cpu .deb package seem to work.

Another option is to rename the function names.

Just my $5.01 (not even worth $5.02).

Cheers,

Hey! sf.net changed my ONE CENT into FIVE DOLLARS AND ONE CENT?
Let's try again: ONE CENT $5.01

8^D
