c - Creating .exe that needs no DLLs or Libraries -

i have project requires use of pthreads. on own computer, have pthread-win32 setup, , can compile project follows, , have work fine.

gcc -o3 engine.c -o engine.exe -lpthread 

the problem is, want able send .exe else not have gcc, , not have pthreads. tried sending computer of mine, , unable run it, throwing error message lpthreads not being installed.

any appreciated, thanks

this may generate gigantic .exe, anyway, use static linking...

gcc -o3 engine.c -o engine.exe -wl,-bstatic -lpthread 

note: strange -wl,-bstatic necessary and correctly typed (it's argument linker).

you need specify -wl,-bstatic before -lmystaticlibrary may specify library want statically-linked. if want other libraries dynamically-linked, pass -wl,-bdynamic after static libraries.

docs (long , boring) here.
