ld cannot find cannot find -luser32 (from Eclipse)

I am trying do CPP development from Eclipse..

I've installed cgywin.. and when try to compile, link any simple Hello World App, I got the following while linking ...

/usr/lib/gcc/i68开发者_开发技巧6-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot find -luser32
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot find -lkernel32

/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot find -lshell32

I think the above libs required by ld is win specific ...

I've tried find / -name *user32*, the result were ..

.....
/usr/i686-pc-mingw32/sys-root/mingw/lib/libuser32.a
......

Is this can help?

From the notice above:

/usr/i686-pc-mingw32/sys-root/mingw/lib/libuser32.a

It really helped me..

The required libs are included under mingw but I am using cygwin in eclipse .. so, under the directory of cygwin which is: /usr/i686-pc-cygwin, I've did the following: ln -sf ../i686-pc-mingw32/sys-root/mingw/lib lib; So, now cgywin have the required libraries ...

I interrupted setup accidentally, and started to see these:

/usr/lib/gcc/x86_64-pc-cygwin/4.8.3/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lshell32
/usr/lib/gcc/x86_64-pc-cygwin/4.8.3/../../../../x86_64-pc-cygwin/bin/ld: cannot find -luser32
collect2: error: ld returned 1 exit status

Ran "cygcheck -c" resulted in all OK

Ran "cygcheck -p libuser32.a" and saw overlap between the two command outputs

Found 9 matches for libuser32.a

w32api-runtime-3.3.0-1 - MinGW-w64 Windows API import libraries for Cygwin

Ran setup again with Reinstall of w32api-runtime and problem solved.
