how to do static linking of libwinpthread-1.dll in mingw?

Question

I use mingw from here: http://sourceforge.net/projects/mingwbuilds/files/host-windows/releases/4.7.2/32-bit/threads-posix/sjlj/x32-4.7.2-release-posix-sjlj-rev2.7z/download

And I've sucessfully managed to link statically libstdc++-6.dll and libgcc_s_sjlj-1.dll by using -static-libgcc -static-libstdc++ parameters, but I cannot find a command for doing the same with libwinpthread-1.dll.

Answer 1

If your toolchain includes the static winpthreads, adding the option

-static 

Will pull in static versions of all libraries it can.

Alternatively, you can remove libwinpthread.dll.a and the DLL itself from the toolchain directories. This might mess up programs linking with libstdc++ and libgcc DLLs though, so be careful.

A third option is to use -Wl,-Bdynamic and -Wl,-Bstatic to select which version you want linked in (which is what -static internally does when ld is called). An example:

gcc -o someexec someobject.o -Wl,-Bdynamic -lsomelibIwantshared -Wl,-Bstatic -lsomelibIwantstatic 

If you run your link command with -v added, you should see these options appearing in the ld/collect2 invocation when you use -static-libgcc and -static-libstdc++.

Answer 2

Try this:

-static-libgcc -static-libstdc++ -Wl,-Bstatic -lstdc++ -lpthread -Wl,-Bdynamic 

Notice the -lstdc++ before -lpthread. It worked for me.

Make sure to add this to the very end of your g++ command line.
