I'm not sure if this is a confgure script problem or not. Please take a look at the related configure error message.
$ configure .... checking for LIBFFI... configure: error: Package requirements (libffi) were not met: No package 'libffi' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables LIBFFI_CFLAGS and LIBFFI_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. # # However when I do: $ ls /bin/*ffi* /bin/cygffi-4.dll This location is standard in my opion. it shows that the ffi library is installed. This is a cygwin platform and library names by convention us 'cyg' as a filename prefix. I'd appreciate any informatio that would help get this built. Thank you.
