i'm stacked with this java c++ integration thing for 4 days. need some help to solve this. thanks in advance

Answer 1

Cygwin and gcc has remove the support of -mno-cygwin flag. Thus, you have to built the source after removing flag.

Another thing due to removal of flag you must have cygwin1.dll available along with your binaries.

If you doesn't want to attach cygwin1.dll then download Mingw compiler and compile through it.
