Hello everyone,

I cannot compile openmc due to the following error:  
$make

Scanning dependencies of target fox\_fsys  
[1%] Building Fortran object xml/fox/fsys/CMakeFiles/fox\_fsys.dir/fox\_m\_fsys\_realtypes.f90.o  
[2%] Building Fortran object xml/fox/fsys/CMakeFiles/fox\_fsys.dir/fox\_m\_fsys\_abort\_flush.F90.o  
/home/jlmiao/openmc/src/xml/fox/fsys/fox\_m\_fsys\_abort\_flush.F90:107.30:

make[3]: \*\*\* [xml/fox/fsys/CMakeFiles/fox\_fsys.dir/fox\_m\_fsys\_abort\_flush.F90.o] Error 1

make[1]: \*\*\* [xml/fox/fsys/CMakeFiles/fox\_fsys.dir/all] Error 2  
make: \*\*\* [all] Error 2

I find it’s because the f95 compiler is too old.  
$ f95 …/src/xml/fox/fsys/fox\_m\_fsys\_abort\_flush.F90 -c -o temp.o

…/src/xml/fox/fsys/fox\_m\_fsys\_abort\_flush.F90:107.30:

stop STDERR\_FAILURE\_STATUS

Error: Syntax error in STOP statement at (1)

My gfortran is up to date  
$ gfortran …/src/xml/fox/fsys/fox\_m\_fsys\_abort\_flush.F90 -c -o temp.o

But cmake chooses f95 by default, How can I change that to gfortan?

$ cmake …/src/  
– The Fortran compiler identification is GNU  
– Check for working Fortran compiler: /usr/bin/f95  
– Check for working Fortran compiler: /usr/bin/f95 – works  
– Detecting Fortran compiler ABI info  
– Detecting Fortran compiler ABI info - done  
– Checking whether /usr/bin/f95 supports Fortran 90  
– Checking whether /usr/bin/f95 supports Fortran 90 – yes  
– Found PythonInterp: /opt/python/2.7/bin/python (found version “2.7.3”)  
– Configuring done

Thanks!

You can force fortran by setting the FC environment variable. So run

> export FC=gfortran

before CMake
