While it might be interesting to find why that isn't working as expected, development of Octave 5 has stopped at the meantime.
Any possible change would go on Octave 6 or later (where this seems to be fixed already).

Fwiw, can you test if you see the same if you use the MSYS2 shell that you can start with "cmdshell.bat" in the folder where Octave is installed?

That file contains the following line for me (maybe related):

set PATH=%OCTAVE_HOME%qt5\bin;%OCTAVE_HOME%bin;%OCTAVE_HOME%python;%PATH%

Thanks for the quick answer. I can confirm that the bug is fixed in the nightly octave-2020-11-15-00-16-w32.

Using octave-5.2.0_1 I still observe the error. I tried this three variations and I don't understand why only the 3rd works:

    1. Start CMD
    2. add mingw32/bin to path
    3. start executable (in tmp folder) -> fail (error message as in initial bug report)
    1. Start CMD
    2. navigate to mingw32/bin,
    3. start executable which is located in tmp folder-> fail (same error as inital bug report)
    1. Start CMD
    2. navigate to mingw32/bin
    3. copy executable to mingw32/bin, start executable -> success

When I use octave-2020-11-15-00-16-w32 all 3 variations work.

I tried to reproduce with a nightly from Kai's buildbots (octave-2020-11-15-00-16-w32.7z):
https://buildbot.octave.space/#/download

The 32bit standalone executed as expected (on a 64bit Windows). This might have been fixed in the meantime...

Building an executable with the Octave 32-Bit Windows release does not work for me. However, using the 64-Bit Windows release works.

Error Message

When I launch the 32-bit exe I get the following error message:

Der Prozedureinsprungpunkt "glBegin@4" wurde in der DLL "C:\Octave\Octave-5.2.0\mingw32\bin\libgl2ps.dll" nicht gefunden.

Which is German (I don't know why this message is in German) for:

The procedure entrypoint "glBegin@4" was not found in "C:\Octave\Octave-5.2.0\mingw32\bin\libgl2ps.dll".

The 64-bit exe doesn't produce a error message.

How to Reproduce

Compile attached test.cpp (taken from the documentation) with the following command in octave-cli:

mkoctfile --link-stand-alone test.cpp

Launch the produced a.exe with the CMD as follows:
When using the 32-bit installation:

set PATH=C:\Octave\Octave-5.2.0\mingw32\bin;%PATH%
a.exe

When using the 64-bit installation:

set PATH=C:\Octave\Octave-5.2.0\mingw64\bin;%PATH%
a.exe

Expected Behavior

The 64-bit variant works as expected and the program outputs the following to the commandline:

GCD of [10, 15] is 5

I would expected that the built standalone executable of the 32-bit release behaves in the same way as the built standalone executable of the 64-bit release does.
