Question

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/i686-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 -ladvapi32
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot find -lshell32

Full output:

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 …
