Hello,
brief info:
got apache + mod_ssl(DSO) + mod_perl(DSO) + mod_frontpage(DSO) work!
Solution: compile everything with '-fPIC'
history and explanation:
Several people ran into problems with running apache and mod_ssl as
DSO unter Solaris, causing a SEGV within SSLeay after the first
restart.
After several discussions and trials Ralf (together with Fritz Elfert ?)
got the error: you have to use -fPIC (position independent code)
on certain platforms as documented within mod_ssl INSTALL file
since version 2.1.7:
[...]
Additionally SSLeay has problems under DSO situations on some
platforms. For instance under smart ix86 platforms like Linux
and FreeBSD when you compile a the standard SSLeay
libcrypto.a/libssl.a libraries and link those to a mod_ssl DSO
libssl.so all works fine. While on other platforms like Solaris
2.6 on a SPARC SSLeay's code will dump core under run-time. When
this is the case for you, then try to recompile SSLeay with
Position Independent Code (PIC) by adding a `-fPIC' (for GCC) or
`-KPIC' (for SVR4-style compilers) to the platform configuration
line in SSLeay's `Configure' script.
on the other hand, this helped just for mod_ssl itself, but not for
other modules dynamically linked against the apache core.
Maybe the solution is to compile just *everything* which is linked
to apache with '-fPIC'. IMHO this is a logically explanation to the
most trouble we had.
I just tried this unter Solaris 2.5.1 with gcc 2.8.1 and everything
works fine :-)
(yes, you have to recompile perl and at least replace 'libperl.a' with
the CORE directory)
best regards,
Jan
