Re: Success : Build OOT module for conda install

Hi Ralf,

Do you have your code/packaging publicly available somewhere that I can
look at? I'd be happy to support your aims of making a package available
for others to use, even to the point of including it in the next
radioconda release if that's appropriate.

I think there's potentially a couple problems that you're running into.

1. The package that you've created still has issues (e.g. finding the
module blocks). This is where seeing exactly what you're doing can help
me to debug.
2. You're building on Linux and want to also create a Windows package.
This is where you would probably need to take advantage of public build
infrastructure to make your package, after you've got it working locally.

What I do to solve (2) is either make a package for conda-forge
(preferred) or build the packages out of a GitHub repository using
GitHub Actions CI. You can find examples of the latter in the
"radioconda" organization:

https://github.com/radioconda

Particularly, these are OOT modules with repositories containing a
.conda directory with packaging information. See e.g. my gr-radar
repository for a concrete example:

https://github.com/radioconda/gr-radar/tree/conda/.conda

Cheers,
Ryan
