 Description   

While trying to build MariaDB Connector ODBC 3.0.2 from source, got the following linking error:

[ 31%] Linking C executable result2
 
/usr/local/mysql/lib//libmariadbclient.a(ma_compress.c.o): In function `_mariadb_compress_alloc':

Editing the CMakeLists.txt file fixed the issue.

Attached the build steps used. Is editing CMakeLists.txt necessary?

We link C/ODBC against Connector/C library, which has zlib compliled in. Please try C/C v.3.0.3

Comment by Faiz Akhtar [ 2018-02-09 ]

Yes I am using using Connector-C 3.0.3. As you can see in build steps attached, I pasted its source code in libmariadb folder of mariadb server before building. Maybe I am missing some step here, or some configure parameter?

Could you please provide your mariadb_config output.

Comment by Lawrin Novitsky [ 2018-02-09 ]

And thank you for your report! We appreciate this

Server builds c/c without compiled in libz, but mariadb_config is supposed to have -lz then. Probably something went wrong in your scenario

-lz seems to be included.

C/C has been made a git sub-module. This should make such linking errors not possible
