Description hanetzer 2017-12-03 20:18:45 UTC
As the title states, you cannot build ncurses with crossdev's
mingw-w64 toolchain without --enable-term-driver passed to the
./configure script. You will end up with the following errors:

../obj_s/lib_kernel.o:lib_kernel.c:(.text+0xe3): undefined reference to `_nc_mingw_tcflush'
../obj_s/lib_kernel.o:lib_kernel.c:(.text+0x12a): undefined reference to `_nc_mingw_tcflush'
../obj_s/lib_ttyflags.o:lib_ttyflags.c:(.text+0x5f): undefined reference to `_nc_mingw_tcgetattr'
../obj_s/lib_ttyflags.o:lib_ttyflags.c:(.text+0x118): undefined reference to `_nc_mingw_tcsetattr'
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:850: ../lib/libncurses6.dll] Error 1

This bug is mostly for documentation purposes, as my pull request
for it (https://github.com/gentoo/gentoo/pull/5734) will address
this issue and also fix bug https://bugs.gentoo.org/631468

    sys-libs/ncurses: fix mingw-w64 build and runtime
    
    *.dll.a files are required for linking on mingw-w64 targets, only delete
    normal static libraries.
    
    --enable-term-driver is required on mingw-w64, otherwise you get a host
    of undefined reference to `_nc_*' errors, and possibly other windows
    platforms/runtimes/toolchains.

    profiles/prefix/windows: p.use.mask tinfo for ncurses
    
    On KERNEL=Winnt, ncurses requires the term-driver option (#639670),
    which conflicts with the termlib option (use.forced by #487844).
