Hi, Stefan!

Thanks! Reported as https://jira.mariadb.org/browse/CONC-303 and fixed at once

This is my favourite reaction to issues in OSS. Thank you very, very much! :-) Stefan

Hi all,

the output of "mariadb_config --libs[_r]" is faulty if the AUTH_GSSAPI plugin is configured as static:

I built mariadb-connector-c 3.0.2 on Fedora 26 with this command:

mkdir build cd build cmake -DAUTH_GSSAPI=STATIC .. make

The output of "mariadb_config" then looks like this:

$ mariadb_config/mariadb_config --libs_r -L/usr/local/lib/mariadb/ -lmariadb -lpthread -ldl -lm -lssl -lcrypto -l-lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err

All libs should be named like "-l<name>" but gssapi_krb5 has a double "-l-l" prefix.

This problems becomes more apparent when I build mariadb-connector-c as a Python Conda package.

Without the "AUTH_GSSAPI=STATIC" flag, I get the following libs:

-L/opt/emsconda/conda-bld/mariadb-connector-c/env/lib/ -lmariadb -lpthread -ldl -lm -lssl -lcrypto

With the "AUTH_GSSAPI=STATIC" flag, I get the following libs:

-L/opt/emsconda/conda-bld/mariadb-connector-c/env/lib/ -lmariadb -lpthread -ldl -lm -lssl -lcrypto -l-L/opt/emsconda/conda-bld/mariadb-connector-c/envplaceho/lib -Wl,--enable-new-dtags -Wl,-rpath -Wl,/opt/emsconda/conda-bld/mariadb-connector-c/envplaceho/lib -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err

The problematic part there is the "-l-L/opt/emsconda/.../lib" part which confuses other tools like Mydumper when they are compiled against mariadb-connector-c.

Is this an issue with mariadb-connector-c or can I fix it in my build process somehow?
