[MOAB-dev] MOAB in Windows (Cygwin/Msys) does not compile

[Vijay S. Mahadevan]

Manuel,

Great to hear that MOAB has been useful for your work. We currently do
not test on Cygwin and so I don't have a machine where I can test a
working build. However, the error due to MB_DLL_EXPORT looks strange.
This is defined in src/moab/Compiler.hpp. Also, I can't see
MB_DLL_EXPORT defined in ExoIIInterface. Do you have local changes
that differ from the latest version or Bitbucket master ?

If you would like to contribute back changes to get the Cygwin builds
working cleanly, we would much appreciate it if you can submit a pull
request in Bitbucket. The Windows support in MOAB is continuously
evolving and user contributions are critical to get this capability
working for different OS/compiler combinations.

Vijay
