# Perlembedd and Qt

• Hi,

I have a project, that compiles and runs just perfectly in C++. Now I am trying to port it to Qt and I get alot of compiling errors:
../Parser/VSymTable.cpp:-1: error:undefined reference to `Perl_Gthr_key_ptr'

Mainly undefined references, so the linker seems to be the problem.

As I don't know how to append files, I just put the files on a server. Maybe someone can help me on how to fix this.

Thank you so much.

• You need to link against the perl libraries in your project. The "Declaring other Libraries":/doc/qt-4.8/qmake-project-files.html#declaring-other-libraries section of the qmake manual has the instructions. You will have to add the libs to the LIBS variable of your .pro file.
