MDAL using debug versions of VS C++ redistributables

[runette]

It have become aware (i.e. when trying to distribute my application) that the Conda compile of MDAL and therefore I believe the standard compile as well (although I have not tested) creates a dependency to the Debug versions of the C++ redistributable on Windows - rather than the release version that most people have installed and is included in Conda.

I.e. it is dependent on :

• vcruntime140d.dll
• ucrtbased.dll
• msvcp140d.dll

rather than:

• vcruntime140.dll
• ucrtbase.dll
• msvcp140.dll

The conda build script see here is not significantly different from the one provided in the readme - except for having -DCMAKE_BUILD_TYPE=Release!

I did always think it was funny that the binaries end up in a Debug folder.

This is a bit of a pain when it comes to redistribution. Does anyone know how to change this?

it is problem of compilation, not CMake. On Windows I think you generate all types of builds (release, debug, ...) ini one folder (compared to linux/mac where you have one build folder per type) and you need to choose when building what you want to build. By default debug. see

this needs to be changed

to

cmake --build . --config Release

Thanks - I will take a look

Fixed in https://github.com/conda-forge/mdal-feedstock/pull/11.

PR #345 added to update docs

Note for the record - this is only fixed in Conda for the 0.8.0 build running on GDL 3.2.2 (and later). The earlier builds will not be fixed.
