Re: Help cross compiling for MingW32 standalone executables.


You are right, I am using the -lm flag.  However, you are wrong in that I am
not using an "older" version of cygwin.  I just ran "setup" and all my
development packages are listed as "keep", meaning
they are the most current stable versions.  For example:

gcc is 3.2-3
gcc-mingw is 20020817-5

I've checked and my build does not like in cygwin1.dll if I edit the
Makefile's by hand to remove the -lm flag.  The problem is the
"AC_CHECK_LIB(m,sqrt)" autoconf macro always report -lm exists and is needed
for the sqrt function when the host target is i686-pc-mingw32.  So anybody
who tries to reproduce my build will have the same problem.
