Undefined references to QtSQL – Raspberry Pi

[DYN]

Hello,

I am having trouble using the SQL module of the qt framework and keep getting undefined reference errors in my code.

I have installed MySQL on the Pi using: sudo apt-get install libmysqlclient-dev mysql-client

Then proceeded to synchronise the sysroot directory in the VisualGDB properties.
Then I included the library name in the VisualGDB project properties, there isn’t a libmysql.a in my sysroot folders, only libmysqld.a and libmysqlclient.a.
I placed mysqlclient in “Library names” field, without the lib prefix and .a extension and  =/usr/local/include =/usr/include/mysql in “library directories” but not sure if this is necessary.
LDFLAGS is empty as I’m not sure what they do.

I have checked these links for info but nothing seems to work for me.

Not sure what else to try,  I’m sure this can be easily resolved but kinda running out of ideas. I’m quite new to VisualGDB and cross-compilation in general.
What am I missing ?
Thanks in advance.

I feel dumb. Just needed to include Qt5Sql in the Library names field.

Hi,

No problem. Library names can sometimes be confusing. Generally searching for *.so and *.a files containing the missing function name usually finds the correct one quickly.
