[opensuse] Problem with libpam.so
Hi - I am wanting to track down and grok a really bad error message in vsftpd which I and a lot of other folks (as reported by Google) are having troubles with. So I decided to try and compile it from source but I ran into a snag, the loader is complaining about the symbols in libpam.so.0 I have verified that the x32 and x64 bit versions of libpam are installed as well as the developer packages. Any gurus around who know why I am getting this belly ache? For reference - OpenSuSE Leap 15.0 x64 bit system. I downloaded the source files for vsftpd as follows - First I determined the package info - marc@bigbang:~/vsftpd> rpm -q --qf '%{disturl}\n' vsftpd obs://build.opensuse.org/openSUSE:Maintenance:8566/openSUSE_Leap_15.0_Update/89aacae22103943e0d60bcb0d3c2b665-vsftpd.openSUSE_Leap_15.0_Update Then use this info with osc to get the source code - marc@bigbang:~/vsftpd> osc co -r 89aacae22103943e0d60bcb0d3c2b665 openSUSE:Maintenance:8566 vsftpd.openSUSE_Leap_15.0_Update I made a #define change in one of the header files to include SSL support (as directed in the documentation) which is the area I am having troubles with.

You'll want to link with the 64-bit version:
# file /lib64/libpam.so.0.84.2 /lib64/libpam.so.0.84.2: ELF 64-bit LSB shared object, x86-64,
Thanks Per, you pointed out the obvious and I am slapping myself on my head! I got to wondering why in the heck the make was trying to load the 32 bit version of the pam library so I dug into the make file. Turns out it uses a "cheesy" script to find and load libraries which defines a library macro to load most libraries with the gcc -l option, EXCEPT for the pam library which the script explicitly defines it to be loaded out of the /lib directory. (yeah this is a bug in the script and I will submit a bug report against it.) This script SHOULD have defined the load with a -lpam option which would have then loaded the right version. Ever onward to solve then next puzzle which seems to be a missing bunch of SSL stuff for vsftpd... I will puzzle on it some but may be back with more questions. ;-) Marc... -- Linux Counter -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Don't do that, you'll only end up bald, like me :-)

You said something about a bad error message from vsftpd - when you've made some progress, maybe keep us in the loop? -- Per Jessen, Zürich (-0.1°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Sure, but maybe I should start a new thread? I have now managed to get past the SSL compilation/link errors I mentioned also and gotten a clean compile/build of vsftpd. These were caused by more mistakes in the script I mentioned - vsf_findlibs.sh which incorrectly tries to determine if/when the SSL and Crypto libs should be linked in or not. I will explain what I have had to do so far to get vsftpd to build, and the problem with vsftpd that I am trying to chase down in a new thread that I will title - "Issues with vsftpd", but let me poke at it a little further first.
