It is a matter of perception regarding usability.
If almost all of the core developers use Linux as their main development environment and the end result for the Linux binary is a sif file, because of compilation/library/… issues, then there is an explicit usability issue for Linux users.
Whereas Windows 10 has native executables with Data Explorer.
The initial perception from the download page is the confidence in the Windows binary.
My initial experience with OGS was using it on a Windows machine.
From that perspective the OS gives an OK plug and chug effect.
But that OS is not the mainstay for reproducible research.
There are native Linux binaries available, which have been compiled but do not necessarily run on Ubuntu 20.04 without the issue of not finding the libraries. Again, a usability issue.
For some reason I have persevered, beyond the call of duty, to understand where and why the compilation fails. This can only improve the perception of usability.
From my perception over the last few days, the experience has been labyrinthine.
But I have solved an important step, getting OGS compiled where the issue was relatively minor.
