Thanks for the reply.
Several things to clear:
1. I have successfully passed the "make && make test && make install" phase.
2. I have moved into "Server configuration" phase and was doing the "mod_perl rocks" thingy, where the error happens.
3. Before seeing your reply, I already found a solution: I renamed Const.so to Const.so.bak (there are several other xxx.so mod_perl complains about, I removed them as well). It works, mod_perl did rock.
4. However this put me into a bigger misery, I can't explain why!!!
After reading the thread, I delved into my setting and found:
- my perl installation doesn't have libperl.so (libperl.a only).
Meaning that you perl is compiled without shared library support.
Currently mod_perl builds itself as static and dynamic, no matter what you choose, so at the later point you can simply link the static archive.- my httpd is DSO enabled. - my mod_perl is mod_perl.so (mod_perl.a is not used).
So it must have the perl library linked in. do you have that symbol that was reported missing in mod_perl.so? (hint: use 'nm')- my mod_perl.so is not linked against ibperl.so.
So I assume that httpd loads mod_perl.so, which loads other xxx.so, such as Const.so, but when does mod_perl load libperl.so (from the thread I assume those undefined symbols would be resolved by libperl.so)? before laoding Const.so? but why did it not complain about no libperl.so on my system?see above.
I suppose that we have a problem here of installing dynamic .so objects, when the static build is used and perl trying to load them. But it's also possible that you've the leftovers from an older install as you suggest below.
Now I start to have some ideas, it must have to do with my Perl installation, which contains some leftovers that should have been cleaned up before I made numerous rebuilds, .... everytime Perl uses a package it looks for *.so by going through @INC, lots of library files with same names.Have you installed mod_perl using the shared libperl.so before into the same directory?
I will let you after I clean up my perl.
