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

by

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++.
