I don’t think this has been mentioned elsewhere, see the [release notes](https://cmake.org/cmake/help/latest/release/3.31.html#compilers) for CMake 3.31 Lfortran is now supported in CMake! 😃 ---

Yes. Please report all bugs. This is a new feature and some things might break. ---

How to use it? I tried lfortran-0.63.0\examples\project1 on Win 10 with cmake 4.3.2. The readme.md says: ```auto To compile with LFortran: FC=lfortran cmake . ``` Have to changed to: ```auto cmake FC=lfortran . ``` The error is: ```auto D:\00masterLib\lfortran-0.63.0\examples\project1>cmake FC=lfortran . -- Selecting Windows SDK version 10.0.26100.0 to target Windows 10.0.19045. -- The Fortran compiler identification is IntelLLVM 2025.1.0 with MSVC-like command-line CMake Error at CMakeLists.txt:3 (project): The CMAKE_Fortran_COMPILER: lfortran is not a full path and was not found in the PATH. Perhaps the extension is missing? ``` I have Intel Fortran on my pc. It found IntelLLVM first, then says lfortran not found. In that folder, I do can start lfortran. My lfortran.exe is at D:\00masterLib\lfortran-0.63.0\inst\bin\lfortran.exe and it is in the PATH. Thanks for help Cean ---

I don’t know how to fix it. I don’t have time right now to debug it myself, but if somebody can help with setting up cmake+lfortran on Windows, that would be highly appreciated. It works on linux/macOS. ---

I uploaded my lfortran\_0.63.0.exe to my google drive. 20.54MB [https://drive.google.com/file/d/11GRJIIPredV8lLlsPljtQHL0FDObDxM6/view?usp=drivesdk](https://drive.google.com/file/d/11GRJIIPredV8lLlsPljtQHL0FDObDxM6/view?usp=drivesdk) After unzip, all under an inst folder. Need to set the inst/bin into Windows 10’s PATH. If lfortran asks some Dlls to run, upzip these into the bin folder. 9.49MB. [https://drive.google.com/file/d/1NWAF8EqfsKtw8uyMTnPC2eQMtaeyPrE8/view?usp=drivesdk](https://drive.google.com/file/d/1NWAF8EqfsKtw8uyMTnPC2eQMtaeyPrE8/view?usp=drivesdk) Because lfortran needs VS’s link to generate exe file, you must have VS installed and run lfortran inside the X64 native terminal. Hope that will help. ---

it might be a CMake for windows thing? Can you use the WSL? ---

Not really want to use wsl. What file and where cmake look for lFortran? Never tried to figure out how the find package works. ---

you can use `cmake --debug-find ../` to see what it is looking for ---

Put full path worked. ```auto cmake -DCMAKE_Fortran_COMPILER="D:/bjbin/lfortran/bin/lfortran.exe" . ``` ---

This generates sln file. When loaded in VS, it is actually build by Intel Fortran on my computer. I should add the -G “Unix Makefiles”. Then it generates makefile file and then can be build by lfortran. Disable my Intel Fortran first, then no need for full path of lfortran.
