Question

I am using ubuntu to build a project that uses mysql. To compile the project from the command line I use the following flags:

$(mysql_config --cflags)$(mysql_config --libs)

However, when I am trying to build from Qt, I get that undefined reference to mysql_close and the rest of mysql connection functions.

I tried adding the representation of the previous command line flags to QMAKe in Qt and still same errors.

Any Help?

Answer 1

Add the output of “mysql_config –cflags” to the compiler flags with:

QMAKE_CFLAGS += $$system(mysql_config --cflags)
QMAKE_CXXFLAGS += $$system(mysql_config --cflags)

Likewise for LIBS:

LIBS += $$system(mysql_config --libs)

All of the above goes into your project file (*.pro) of course.
