Error compiling mfemm - R2022a Windows

[pierrepesc]

Hi,

First time xfemm user. I tried to set up the matlab interface to xfemm by running mfemm_setup(). It started compiling nicely (see below) but then I got an error

>> mfemm_setup()

mex -c -O -D_GLIBCXX_USE_CXX11_ABI=1 -I"../cfemm/fmesher" -I"../cfemm/fmesher/triangle" -I"../cfemm/libfemm" -I"../cfemm/libfemm/liblua" -DCPU86 -DNDEBUG  GCC="$GCC" OPTIMFLAGS="" CXXFLAGS="$CXXFLAGS -std=c++11  -fpermissive" LDFLAGS="$LDFLAGS -static-libstdc++ '-Wl,--no-undefined'" C:\Users\hp\Downloads\xfemm-master\xfemm-master\mfemm\..\cfemm\libfemm\liblua\femmcomplex.cpp -outdir C:\Users\hp\Downloads\xfemm-master\xfemm-master\mfemm\..\cfemm\libfemm\liblua
Building with 'MinGW64 Compiler (C++)'.
MEX completed successfully.

... on and on until I got the following error

mex -c -O -D_GLIBCXX_USE_CXX11_ABI=1 -I"../cfemm/fmesher" -I"../cfemm/fmesher/triangle" -I"../cfemm/libfemm" -I"../cfemm/libfemm/liblua" -DCPU86 -DNDEBUG  GCC="$GCC" OPTIMFLAGS="" CXXFLAGS="$CXXFLAGS -std=c++11  -fpermissive" LDFLAGS="$LDFLAGS -static-libstdc++ '-Wl,--no-undefined'" C:\Users\hp\Downloads\xfemm-master\xfemm-master\mfemm\..\cfemm\libfemm\femmversion.cpp -outdir C:\Users\hp\Downloads\xfemm-master\xfemm-master\mfemm\..\cfemm\libfemm
Building with 'MinGW64 Compiler (C++)'.
Error using mex
C:\Users\hp\Downloads\xfemm-master\xfemm-master\cfemm\libfemm\femmversion.cpp:1:25: fatal error: femmversion.h: No such file or directory
 #include "femmversion.h"

when I looked in C:\Users\hp\Downloads\xfemm-master\xfemm-master\cfemm\libfemm I saw that the file was actually called femmversion.h.in ? I tried to rename it to simply femmversion.h and ran again mfemm_setup but then got this issue (only pasting below the beginning of the error:

Error using mex
In file included from C:\Users\hp\Downloads\xfemm-master\xfemm-master\cfemm\libfemm\LuaInstance.cpp:21:0:
C:\Users\hp\Downloads\xfemm-master\xfemm-master\cfemm\libfemm\femmversion.h:21:28: error: stray '@' in program
 #define FEMM_VERSION_MAJOR @XFEMM_VERSION_MAJOR@

I'm a bit stuck with that, would appreciate a hand.

Thanks

@reos-rcrozier ?

Yes, you need to first run cmake on the cfemm folder to generate this file, then mfemm_setup will work

[pierrepesc]

Thanks a lot, didn't read the instructions well enough...

So not sure I compiled it correctly as Matlab is consistently crashing when running mexfmesher...

Below is the summary of the cmake

Would you have any suggestions? Could it be linked to the "CMake Warning at fmesher"?

Thanks!
