[slurm-users] Need help with controller issues

[Dean Schulze]

I tried again with a completely new system (virtual machine).  I used the
latest source, I used mysql instead of mariadb, and I installed all the
client and dev libs (below).  I still get the same error.  It doesn't
build the /usr/lib/slurm/accounting_storage_mysql.so file.

Could the ./configure command be the problem?  Here's how I run it:

./configure --prefix=/tmp/slurm-build --sysconfdir=/etc/slurm --enable-pam
--with-pam_dir=/lib/x86_64-linux-gnu/security/ --without-shared-libslurm
