Error 127 during compiling

[AmirrezaHBSH]

Hello, I would appreciated if you could help me with this problem.

I am using this command in Putty "git clone [email protected]:firemodels/fds.git" to get FDS, then when I am trying to compile it, I am getting an error which is error 127 (ignored) and this is occurring for all the source file such as:

make: [../makefile:144: main.o] Error 127 (ignored)

Could you please explain me how I need to address this problem?

Can you be more specific? For example, what is your operating system? Which compiler do you have? What script did you invoke?

My operating system is Windows in my local computer and linux for the supercomputer. I trying to compile make_fds.sh file located in ompi_gnu_linux

Error 127 is a path error.

In the window where you are trying to build FDS:

1. Make sure you are building inside the build subdirectory for your compiler, operating system, and build type (e.g. release, debug) and not in the main Build folder. You want to be running a make_fds.sh or make_fds.bat script file and not just typing make at the command line.
2. Make sure git is in your path for that window.

A detailed set of compilation instructions can be found here:

Yes I am trying to build FDS inside the ompi_gnu_linux which is located in Build folder and also I am running make_fds.sh.

I have tried the exactly same steps to the other account and there was no issue with it

Fatal error, no input file.

I have done this compilation and downloading several times. I am exactly following the same steps that I did before. But error 127 is occurring

I have the same problem. It is located in the /usr/bin/ directory, and the version is GNU Fortran 8.5.0.

[gforney]

what is the output of
which mpifort

[SaharRasoulpour]

Here is the output of the which mpifort:
/usr/bin/which: no mpifort in (/apps/x86 64/apps/lua_5.4.4/bin:/usr/share/Modules/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sysopt/pbs/bin:/scripts:/sysopt/pbs/bin:.)

[gforney]

thanks. that is the problem. go to this page
https://github.com/firemodels/fds/wiki/Setting-up-Linux-environment
and install openmpi and other missing packages

[SaharRasoulpour]

I installed OpenMPI, and the output of which gfortran is:
/apps/x86-64/apps/spack_0.21.2/spack/opt/spack/linux-rocky8-zen3/gcc-12.2.0/gcc-12.3.0 rwmy6jlsobgceqlfioja7crnnpbz2s7v/bin/gfortran
The output of which mpifort is:
/apps/x86-64/apps/openmpi_4.1.7_gcc12/bin/mpifort
However, when I navigate to the build directory for OpenMPI_gnu and run the build script using ./make_fds.sh, I still encounter the same error 127.
