Incompatible display to run linuxdoom

[HotCoffee]

I'm trying to port the original linuxdoom released in 1996 to Ubuntu, I've got the source to compile after making some changes but now it won't run because it requires a screen with 8 bit color depth, and a "PseudoColor" display, I've tried changing the depth in the source code but the problem is the images that are getting drawn are 8 bits depth so I really don't know how I could convert them.

Not sure if it's of any help to you, but I had this issue too.

Have a look, this can be helpful as well: http://sauparna.sdf.org/Doom/Compile_Doom ("XEPHYR: A 'NESTED' X SERVER, RENDERS 8 BPP" section).

DoomLegacy is related to linuxdoom.

DoomLegacy is developed on Linux Slackware, so that should not be a problem.

Our 8bit draws work on current Linux Slackware.

The code has a ports for SDL, and X-windows direct drawing, as selected at compile-time by make_options.

 

It has added draw routines for 8bit, 15bit, 16bit, 24bit, and 32bit screens.  The user can select which draw mode they want.

It has been heavily modified for readability, bug fixes, has added features, but is still C code, and can be visually compared to PrBoom source.

I suggest you borrow what code you need.  LINK: doomlegacy_home_page
