A :: environment setup
-----------------
# download and install MSYS2

/!\ **ALWAYS** launch MSYS2 32bits (you must see MINGW32 into the prompt)


# update pacman and other packages
pacman -Syu

# exit console
# update other packages
pacman -Syu

# install gcc and dev toolchain
# /!\ don't install iconv for OpenSP
# DONOT: pacman -S mingw-w64-i686-binutils mingw-w64-i686-gcc mingw-w64-i686-gcc-libs mingw-w64-i686-gcc-objc mingw-w64-i686-make mingw-w64-i686-pkg-config
pacman -S mingw-w64-i686-toolchain


B :: compile libopensp 1.5.2
-----------------------
# get source code :: https://sourceforge.net/projects/openjade/files/opensp/1.5.2/OpenSP-1.5.2.tar.gz/download
# unzip into /home/<user>

cd ./OpenSp-1.5.2

#1) apply those gnucash patch (by patch or by hand with text editor)
wget https://github.com/Gnucash/gnucash-on-windows/blob/master/opensp-1.5.2.patch
wget https://raw.githubusercontent.com/Gnucash/gnucash-on-windows/master/patches/OpenSP-1.5.2-non-posix-functions.patch

#2) configure
# options taken from gnucash https://github.com/Gnucash/gnucash-on-windows/blob/master/gnucash.modules#L208
./configure --disable-static --enable-shared --disable-doc-build --disable-nls --prefix=/mingw32

#3) AFTER, WE MUST modify with text editor : Makefile line 105/106 (/lib/MakeFile.in)
- Fixed4CodingSystem.lo memcmp.lo memmove.lo strerror.lo 
+ Fixed4CodingSystem.lo memcmp.lo memmove.lo strerror.lo \
+ WinInetStorage.lo WinApp.lo Win32CodingSystem.lo

#4) build it !
make

# we have a lot of warning here 
# and the build fail on ospcat.exe
# BUT we don't care as we do have what we need into /libs/.libs

#5) install
make install

# IF it fails, copy by hand into:
#- C:\msys64\mingw32\bin\lib\libosp-5.dll
#- C:\msys64\mingw32\include\OpenSP (145 files)
#- C:\msys64\mingw32\lib
#	libosp.dll.a
#	libosp.la
#	libosp.lai
#- C:\msys64\mingw32\share\OpenSP (28 files)

#6) we are ready to compile libofx !

# =============================================================================

C :: Compile libofx
---------------------
# get source code from https://sourceforge.net/projects/libofx/files/libofx/ 
(taken 0.9.14)

#1) configure
./configure --prefix=/mingw32 --with-opensp-includes=/mingw32/include/OpenSP --with-opensp-libs=/mingw32/lib

# DONOT other option: 
#   --with-iconv=/mingw32 
# not usefull as OpenSP is compiled with SP_MULTI_BYTE 1 
#   --with-no-opensp-multibyte

#2) build !
make

#3) make package
make dist

#this failed with infinite loop on 'y' on the console
#so I maked a package by hand

# ** THE END **

A) force some 'const char' as 'char' in \lib\ofx_preproc.cpp
  - line ~315 replace the 2 const char** with char**

3) comment line in win32.hh and win32.cpp
