Troubleshooting Visual Studio Command Prompt Integration Issue

Issue Description

Nmake and ifort are not recognized from a command window, however using Intel Fortran under Visual Studio works perfectly.

Troubleshooting

Follow below checklist to troubleshooting Visual Studio command environmental issues:

1. Verify whether ifort and nmake are installed correctly:

    For Visual Studio 2017, nmake is installed at:

    C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.10.25017\bin\HostX64\x64\nmake.exe

    Find this by running below commands from a system ifort or nmake setup correctly:

> where nmake
  > where ifort

    Also check whether the location is included from PATH environment:

> echo %PATH%

2. If nmake can be found, verify if VS setup script runs properly.
    Start a cmd window, and run Visual Studio setup script manually:

> "C:\Program Files (x86)\Microsoft Visual Studio\2017 \Professional\VC\Auxiliary\Build\vcvars64.bat"

    An expected output is as below

> "C:\Program Files (x86)\Microsoft Visual   Studio\2017\Professional\VC\Auxiliary\Build\vcvars64.bat"
  \Common was unexpected at this time.

> set VSCMD_DEBUG=3

> "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Auxiliary\Build\vcvars64.bat"> setup.log 2>&1
