Mariadb-10.4.8 configure error - Plugin AUTH_PAM cannot be built
 

Slackware-current 64 bit, last updated this morning 9/16/2019.

I'm trying to build Mariadb-10.4.8 from source, using their mysql config:

cmake ../ -DBUILD_CONFIG=mysql_release

And it gives this error

CMake Error at cmake/plugin.cmake:284 (MESSAGE):
Plugin AUTH_PAM cannot be built

Comparing the file mysql_release.cmake to the 2.4.7 version, I find this line has been added:

SET(PLUGIN_AUTH_PAM YES)

If I change it to NO, then it builds up to this point:

[ 52%] Building CXX object storage/rocksdb/CMakeFiles/rocksdblib.dir/rocksdb/env/io_posix.cc.o
[ 52%] Building CXX object storage/rocksdb/CMakeFiles/rocksdblib.dir/build_version.cc.o
[ 52%] Linking CXX static library librocksdblib.a
[ 52%] Built target rocksdblib
make: *** [Makefile:163: all] Error 2

At which point it dies. Line 163 of the Makefile is

$(MAKE) -f CMakeFiles/Makefile2 all

Makefile2 exists, and at this point idk wtf is up or why it won't continue to build...

I tried the SlackBuild for 10.4.7, same thing. On the same box, Mariadb-10.4.7 builds just fine, both manually and with the SlackBuild.

Anyone else tried to build Mariadb-10.4.8?

PS I'm running Slackware-current, last updated this morning 9/16/2019.

Slackware has no LinuxPAM support.

I know. That is why I disabled it. I don't think that is why it died when it did, but since it didn't tell me why, I can't be sure.

This seems to be where it dies:

/usr/bin/ld: skipping incompatible /usr/lib/libtinfo.so when searching for -ltinfo
/usr/bin/ld: cannot find -ltinfo

In the past, I would symlink libtinfo to libncurses to get past this, but this seems to no longer work.

Slackware -current has a proper libtinfo, and also ships already with mariadb-10.4.8. The patch for the cmake config is the same as what you found in the OP. Not sure what's wrong with your box, but the -ltinfo issues don't happen here. I'd suggest reinstalling the ncurses package as any libtinfo hacks aren't needed anymore and would probably just cause breakage.

So I removed my libtinfo hacks, and reinstalled the ncurses package, as you suggested. I then ran into problems with the mariadb build provided by mariadb:

mysql
mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

Looked a bit closer and found:

ldd mysql
libncurses.so.5 => not found
libtinfo.so.5 => not found

The build provided by Mariadb appears to have been compiled against the .5 version of libncurses and libtinfo. I looked at the version that comes with Slackware:

ldd mysql
libncurses.so.6 => /lib64/libncurses.so.6 (0x00007f9e2624a000)
libtinfo.so.6 => /lib64/libtinfo.so.6 (0x00007f9e26219000)

So I built mariadb using the slackbuilds script, and it worked. I then built it from source, modifying the mysql_release.cmake to not use PAM, and again it works. Cleaning up my ncurses and libtinfo mess seems to have fixed the problem.

Lesson learned: Don't rely on the build provided by Mariadb. This is not the first time I got bit by trying to use their build, I guess I did not learn my lesson the first time.

That's the thing about running other people's binaries, they aren't compiled for your distribution. It's probably built on an older Ubuntu or something.

I expect that more often than not, with third party binaries and if I take such a shortcut, I expect it to fail one day after library changes. It's best to compile, or use a package built for the correct version of your distro.

Agree 100%. For my production systems, I always compile from scratch. That way it's not only compiled for my build, but it's compiled *my way. I manage several Linux servers used for fax, web, email and apps, and they are pushing 100% uptime. The only downtime I can think of that was attributed to a linux problem was when they broke an ssh2 lib for php and I had to scramble to find/compile/install an older version to get it working again. That is the *only botched update I've ever seen for Slackware.

I wish i could have a dollar for every botched Windows update I've seen...

I want $100 for every one, for the unbillable time it has cost me :-)
