Hi, I encountered an issue while trying to follow the steps outlined in "MinGW-w64: GNU Fortran on Windows" and am unable to resolve it.I would be grateful if someone could offer assistance and help me resolve this issue！！

I suspect this happens because you are using version 8 of MinGW (gfortran). This version is too strict in its checking of array contiguity. You can work around this issue by switching FABM_USE_CONTIGUOUS to OFF in cmake (see also https://github.com/fabm-model/fabm/wiki/Building-and-installing#supported-compilers). And if you are indeed using version 8.x of MinGW, you could also upgrade to a later version instead.

Thank you for helping! I tried these methods but still going through the same problem. I think I'm gonna try to use Linux to install fabm and hope it can work well! !

Ok. Just to note: if FABM_USE_CONTIGUOUS is truly OFF, there are no contiguous arrays used by FABM at all, which means that this specific error ("Assignment to contiguous pointer...") can no longer occur. Thus, I suspect that FABM_USE_CONTIGUOUS=OFF was not recognized by cmake. Note that if you are using CMake-GUI, you'll have to first check "Advanced", and then you can switch off FABM_USE_CONTIGUOUS:

After that, you'll have to click "Configure" and "Generate" again before you rebuild.

Thank you for your patient help! This time it works. I only changed FABM_USE_CONTIGUOUS in the CMakelists file, and after checking in CMake-GUI the installation worked! Thank you so much!!
