Here are the requirements for "gcc-core": binutils, cygwin-devel, libatomic1, libgomp1, libisl15, libmpc3, libquadmath0, libssp0, w32api-headers, w32api-runtime, windows-default-manifest
and for "w32api-runtime": w32api-headers Here are the requirements for "mingw64-x86_64-gcc-core": libisl13, libmpc3, mingw64-x86_64-binutils, mingw64-x86_64-headers, mingw64-x86_64-runtime, mingw64-x86_64-windows-default-manifest, mingw64-x86_64-winpthreads and for "mingw64-x86_64-runtime": libisl13, libmpc3, mingw64-x86_64-binutils, mingw64-x86_64-gcc-core, mingw64-x86_64-headers, mingw64-x86_64-windows-default-manifest, mingw64-x86_64-winpthreads so "mingw64-x86_64-gcc-core" and "mingw64-x86_64-runtime" require each other. I think that the requirements for "mingw64-x86_64-runtime" should be adjusted on so that they are similar to "w32api-runtime". -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
