[odb-users] Cannot Compile ODB Compiler on RHEL 8.5

[Tyler Lytle]

I think I am going down a rabbit hole of RPM issues. The RHEL 8.5 ISO that
contains the RedHat provided repository does not seem to have a plugin
support package for GCC 8. But, weirdly, it has plugin support packages for
GCC 9, 10, and 11. I don't quite understand what I'm looking at or how to
find things so I went a different route. I instead downloaded the
precompiled ODB 2.4.0 RPM from the Code Synthesis website and installed
that and I am now making headway. The runtime ODB library was able to be
built and installed correctly. Now, I am trying to build and install the
MySQL runtime library. I am getting the following error during
configuration:

[tlytle at localhost libodb-mysql-2.4.0]$ ./configure
...
configure: error: libmysqlclient_r is not found; consider using
CPPFLAGS/LDFLAGS to specify its location

Looking in /usr/lib64/mysql, the only MySQL related libraries are
these: libmysqlclient.so  libmysqlclient.so.21  libmysqlclient.so.21.1.26

Looking around on the web, the libmysqlclient_r library is no longer
distributed with newer versions of MySQL as the libmysqlclient.so library
is now re-entrant, rendering the libmysqlclient_r.so library meaningless.
To bypass this, I just created a symlink named libmysqlclient_r.so to
libmysqlclient.so.

After doing this, I can now get configure to work. However, when trying to
make the libodb-mysql runtime library, I get a mountain of errors. If you
want, I can copy-paste these in a separate e-mail or get them to you some
other way, but it is a lot of compilation errors. The make commands are as
follows:

[tlytle at localhost libodb-mysql-2.4.0]$ make
Making all in odb/mysql
make[1]: Entering directory
'/home/tlytle/repos/common/odb/libodb-mysql-2.4.0/odb/mysql'

-DLIBODB_MYSQL_DYNAMIC_LIB -g -O2 -D_REENTRANT -MT connection.lo -MD -MP
-MF .deps/connection.Tpo -c connection.cxx  -fPIC -DPIC -o
.libs/connection.o

Just one example of the errors in the output:

                 from ../../odb/mysql/database.hxx:18,
                 from connection.cxx:8:
