SDL2 unable to set colors correctly

[wmcbrine]

Since it works in the general case (see the “testcurs” demo), I need a complete example program that works under ncurses and not under PDCurses.

Yes. I should have posted full context in the initial post, this is the project and relevant source file.
If it is not very helpful, I'll try to recreate it later into a smaller test case.

I'm going to look at the demo code following your suggestion and compare. Maybe pdcurses is sensitive to initialization order in ways that ncurses isn't.

I believe I have managed to reproduce a color problem out of the program.
Test case

This program will give two different color outputs in pdcurses and ncurses.
Ncurses backgrounds output in blue, like asked, whereas pdcurses outputs in red.

Yeah, that one's got nothing to do with init_color() per se, but with mixing symbolic and numeric color references (numeric in your init_color() calls, and symbolic in init_pair()). See, by default, PDCurses defines COLOR_BLUE as 1, and COLOR_RED as 4, while ncurses defines COLOR_RED as 1 and COLOR_BLUE as 4. You can change PDCurses' behavior by defining PDC_RGB at build time.

This is handled in testcurs via the colors[] table in colorTest(), which is just a list of the color symbols in the desired order, with init_pair() and init_color() referencing colors[i] instead of just i.

It works now! I have defined PDC_RGB and the colors are in order.
Thanks for your help. 👍
I close this issue since there isn't actually a bug.
