This is not a search and replace of __MING32__ with _WIN32. There are places where __MINGW32__ is still used and all changes are tested with MSVC 2019 compiler. Although, this commit alone will not work on MSVC because there are plenty of other things to be done which are seperated into multiple PR. PR OSGeo#289 is the one that "works" on MSVC and unix as well. But that contains too many changes which shouldn't in a single PR. Even though this PR alone won't compile GRASS GIS on MSVC, it sure will not break existing compilers which I think is very important. Complete support for MSVC will be ready after 2/3 PRs OSGeo#289
static int initialized is not working for MSVC and must export this with __declspec so that it appears in a DLL correctly. This change has been tested on Ubuntu and MSVC 2019 and is working as expected.
Below is a code from filldepr.cpp which throws error on msvc compiler
function has G_fatal_error() so it is 'normal' to have no return type.
But MSVC complains that function's return type is elevation_type*
and does not return anything.
elevation_type*
ext_fill_depression(AMI_STREAM<boundaryType> *boundaryStr,
cclabel_type maxWatersheds) {
G_fatal_error(_("Fill_depressions do not fit in memory. Not implemented yet"));
}
The MSVC compiler only supports C90, it does not support C99 and variable length arrays are a feature of C99.
g.list uses regex.h which is not available on MSVC. This PR fixes g.list by using pcre library on windows and use regex.h on other platforms. This is Work in progress. Need to test the functionality of pcre v. regex

I don't have a good suggestion on how to do it in this case because you need the CMake PR changes to make all the other things work. The only way I see is having the CMake changes in the source code uncommitted. However, given the current state, it might be sufficient to resolve this only after the CMake PR is merged. The CMake support might not be finished, but the PR is close to something which could be merged. |
