###################### NOTES #####################

# - This file goes together with MakeCoq_ForMignGW.bat, which sets up cygwin
#   with all required packages and then calls this script.
#
# - This script uses set -o errexit, so if anything fails, the script will stop
#
# - cygwin provided mingw64 packages like mingw64-x86_64-zlib are installed to
#   /usr/$TARGET_ARCH/sys-root/mingw, so we use this as install prefix
#
# - if mingw64-x86_64-pkg-config is installed BEFORE building libpng or pixman,
#   the .pc files are properly created in /usr/$TARGET_ARCH/sys-root/mingw/lib/pkgconfig
#
# - pango and some others uses pkg-config executable names without path, which doesn't work in cross compile mode
#   There are several possible solutions
#     1.) patch build files to get the prefix from pkg-config and use $prefix/bin/ as path
#         - doesn't work for pango because automake goes wild
#         - mingw tools are not able to handle cygwin path (they need absolute windows paths)
#     2.) export PATH=$PATH:/usr/$TARGET_ARCH/sys-root/mingw/bin
#         - a bit dangerous because this exposes much more than required
#         - mingw tools are not able to handle cygwin path (they need absolute windows paths)
#     3.) Install required tools via cygwin modules libglib2.0-devel and libgdk_pixbuf2.0-devel
#         - Possibly version compatibility issues
#         - Possibly mingw/cygwin compatibility issues, e.g. when building font or terminfo databases
#     4.) Build required tools for mingw and cygwin
#         - Possibly mingw/cygwin compatibility issues, e.g. when building font or terminfo databases
#
#   We use method 3 below
#   Method 2 can be tried by putting the cross tools in the path before the cygwin tools (in configure_profile.sh)
#
# - It is tricky to build 64 bit binaries with 32 bit cross tools and vice versa.
#   This is because the linker needs to load DLLs from C:\windows\system32, which contains
#   both 32 bit and 64 bit DLLs, and which one you get depends by some black magic on if the using
#   app is a 32 bit or 64 bit app. So better build 32 bit mingw with 32 bit cygwin and 64 with 64.
#   Alternatively the required 32 bit or 64 bit DLLs need to be copied with a 32 bit/64bit cp to some
#   folder without such black magic.
#
# - The file selection for the Coq Windows Installer is done with make install (unlike the original script)
#   Relocatble builds are first configured with prefix=./ then build and then
#   reconfigured with prefix=<installroot> before make install.
