windows - Chocolatey generated VS 2015 Compiler not found on docker image

Question

I tried to install visual studio 2015 build tools on a Docker Container using the chocolatey packet manager. I need it for a Matlab code gen build operation. The chocolatey steps works fine. But my docker container can't find the compiler. Any Hints?

Docker

RUN powershell -command choco install -y vcredist140
RUN powershell -command choco install -y vcbuildtools -ia "/Full"

Using mex -v -setup I have:

Did not find installed compiler 'Microsoft Visual C++ 2015 (C)'.

Answer 1

After some exploration, I found that:

1. mex -v -setup lookup table is in C:Program FilesMATLABR2017binwin64mexoptsmsvcpp2015.xml

2. Matlab needs specifics VS7 registry values to say that a VS 2015 compiler is installed.

3. Chocolatey only Install VC7 registry values.

If you add this to a docker file or run line in CLI container:

RUN reg add  HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftVisualStudioSxSVS7 /v 14.0 /t REG_SZ /d "C:Program Files (x86)Microsoft Visual Studio 14.0VC"

It fixes the issue.

msvcpp2015.xml

        <VSINSTALLDIR>
            <or>
                <hklmExists path="SOFTWAREMicrosoftVisualStudioSxSVS7" name="14.0" />
