Dear all,
I am trying to build the windows versions of the openbabel library, so
that I could build a windows
version of my program that uses openbabel.
I use msys/mingw64.
I downloaded version 2.4.1 of the sources, followed the instructions I
could find, somehow the
compilation is a success but I am stuck at some point by the gamess
input file that requires
things that are already installed ... and for some reason not found ...
At the cmake stage I used:
cmake -G "MSYS Makefiles" ../openbabel-2.4.1 -DBUILD_GUI=OFF
To pass that stage I had to delete some lines in
"openbabel-2.4.1/CMakelists", lines that were ensuring to use GXX
version > 4.2,
indeed the Cmake wasn't able to parse string result of the g++ version
inquiry for msys/mingw ... too long or unexpected symbols ...
after deleting the lines it works, up to some point in the compilation
process:
Here is the output of "make" at this error point:

---------------------------------------------------------------------------------------------------------------------------------------------------------------
The file "regex.h" in "mingw64/include" define "recomp", "regexec" and
"regfree" (I checked),
is there anyway to require _not to build_ the gamessukformat ?
Any other option to build the devel lib/files for windows ?
Thanks in advance for you help.
Sébastien
