Subject: Re: "undefined ref to 'flock'" when compiling 1.8 under cygwin

Hi,

Thanks. With latest CVS it now works fine to compile for cygwin
(configure --enable-shared) but when I try to make it use mingw32
there is still a problem:

$ ./configure --with-gcc='gcc -mno-cygwin' --enable-shared
<snip>
$ make
<snip>
gcc -mno-cygwin -g -O2    main.o dmyext.o libmsvcrt-ruby18-static.a
-lwsock32
-o miniruby.exe
libmsvcrt-ruby18-static.a(numeric.o): In function `flo_to_s':

undefined ref
erences to `__fpclassify' follow
collect2: ld returned 1 exit status
make: *** [miniruby.exe] Error 1

Any ideas?

Thanks,

Karsten
