Hi, After updating my system, libmcal broke. This resulted in apache not starting on my system, which was a major disapointment :-( Reproducible: Always Steps to Reproduce: 1. # emerge --deep --update world 2. # /etc/init.d/apache2 start Actual Results: root@caronia plp $ /etc/init.d/apache2 start * Apache2 has detected a syntax error in your configuration files: Syntax error on line 5 of /usr/lib/apache2/conf/modules.d/70_mod_php.conf: Cannot load /usr/lib/apache2/extramodules/libphp4.so into server: /usr/lib/libmcal.so: undefined symbol: pam_end root@caronia plp $ ld /usr/lib/libmcal.so ld: warning: cannot find entry symbol _start; not setting start address /usr/lib/libmcal.so: undefined reference to `pam_end' /usr/lib/libmcal.so: undefined reference to `pam_authenticate' /usr/lib/libmcal.so: undefined reference to `pam_setcred' /usr/lib/libmcal.so: undefined reference to `cc_login' /usr/lib/libmcal.so: undefined reference to `pam_set_item' /usr/lib/libmcal.so: undefined reference to `cc_searched' /usr/lib/libmcal.so: undefined reference to `cc_vlog' /usr/lib/libmcal.so: undefined reference to `cc_vdlog' /usr/lib/libmcal.so: undefined reference to `pam_start' To quick-and-dirty fix this, I had to do: # USE="-pam" emerge libmcal Expected Results: Apache should start. No undefined references in libmcal.so.

please specify WHAT you upgraded that broken libmcal, and if re-merging libmcal (with your normal USE flags) works.
Same thing here. I upgraded libmcal to the latest release in portage as of August 28th 2004, and mod_php broke. I had "pam" in my USE flags for libmcal and mod_php. Even re-emerging mod_php after mcal update, the compilation dies when building the mcal extension (with some undefined references to pam_***).
please sync and then attach the full output of 'emerge mcal'.

Sorry for taking so long guys. I was away from computers all weekend. Attached above are the outputs of "emerge libmcal". The problem happens when you try to emerge libmcal without the -pam flag.
pantelis: could I please get the output of /usr/lib/libmcal.so
typod that. ldd /usr/lib/libmcal.so is the output I want

Same output here, if emerged with pam. With -pam, there are still undefined references, but Apache works OK: root@caronia plp $ emerge libmcal . . . root@caronia plp $ ld /usr/lib/libmcal.so ld: warning: cannot find entry symbol _start; not setting start address /usr/lib/libmcal.so: undefined reference to `cc_login' /usr/lib/libmcal.so: undefined reference to `crypt' /usr/lib/libmcal.so: undefined reference to `cc_searched' /usr/lib/libmcal.so: undefined reference to `cc_vlog' /usr/lib/libmcal.so: undefined reference to `cc_vdlog' root@caronia plp $ USE="-pam" emerge libmcal . . . root@caronia plp $ ld /usr/lib/libmcal.so <same output as Romang's>
Sorry, I forgot about ldd. Output is the same as Romang's in all cases.
Created attachment 38684 [details] Modified libmcal ebuild Please find attached a modified ebuild for libmcal that fixes this problem for me. Robin: what I did was to add a -lpam to the CFLAGS of the library make.
does your fix allow you to successfully compile php as well afterwards?
Both php and mod_php compile and work properly.
fixed in cvs.
