Add library linker command line

[jvillain]

I get the following and the money line would appear to be

/usr/bin/ld: /tmp/ccOBy7h6.o: undefined reference to symbol 'sem_timedwait@@GLIBC_2.2.5'
/usr/bin/ld: note: 'sem_timedwait@@GLIBC_2.2.5' is defined in DSO /lib64/libpthread.so.0 so try adding it to the linker command line

How do I add /lib64/libpthread.so.0 to the linker line?

I am running Fedora 13. I had successfully built a previous version on Fedora 12.

Thanks

Try to add "-lpthread" to CFLAGS or CXXFLAGS or LDFLAGS in Makefile, whichever is used for the final gcc linking command (I don't have the Makefile here right now to check myself).

[jvillain]

Thanks for your help. Adding -lpthread moved the goal post and -lrt got it to build clean. The full line is below for when the Fedora guys upgrade to 13 and start running into this.

-I/usr/include/qt4 -I/usr/lib/qt4/include -L/usr/lib/qt4 -L/usr/lib/qt4/lib -lc -lstdc++ -lQtGui -lQtCore -lpthread -lrt

[mike admin]

Can you please check what happens if you add "-lpthread -lrt" before "-lQtGui -lQtCore", right after "-lc -lstdc++"?

I get this error when compiling in debian. Where are you putting that line?

edit ** nevermind. jvillain's adjustment fixed it.
