Console window pops up when using Simd library on Windows in GUI application #268

Closed janrysavy closed 4 months ago

janrysavy commented 4 months ago

When invoking the std::string Execute(const char* cmd) function (during Simd initialization), which internally calls _popen, a console window briefly appears. This behavior is disruptive, especially in GUI application.

Hi! Thank you for bug report. I added this issue to roadmap.

Would you be interested in pull request? Use CreateProcess instead of _popen on Windows? Unfortunately it would by more verbose solution.

Lazy loading in this case would be probably also a good idea.

Hi! Certainly it will be greate if you make a pull request with solution of this issue. I think it will be something based on this:

Of course, if it doesn't cause any bothes for you.
