"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

$ make

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': /tmp/ruby/numeric.c:280: undefined reference to__fpclassify’
libmsvcrt-ruby18-static.a(numeric.o): In function flo_is_infinite_p': /tmp/ruby/numeric.c:731: undefined reference to__fpclassify’
libmsvcrt-ruby18-static.a(numeric.o): In function flo_is_finite_p': /tmp/ruby/numeric.c:744: undefined reference to__fpclassify’
libmsvcrt-ruby18-static.a(bignum.o): In function dbl2big': /tmp/ruby/bignum.c:786: undefined reference to__fpclassify’
libmsvcrt-ruby18-static.a(bignum.o): In function rb_big2dbl': /tmp/ruby/bignum.c:827: undefined reference to__fpclassify’
libmsvcrt-ruby18-static.a(marshal.o):/tmp/ruby/marshal.c:198: more
undefined ref
erences to `__fpclassify’ follow
collect2: ld returned 1 exit status
make: *** [miniruby.exe] Error 1

Any ideas?

Thanks,

Karsten

I think that your gcc is old. It has not taken adjustment
with the mingw-runtime. I suggest you upgrade to the latest
version of the gcc package.
