This is part of the CMake update project #748
The README.md needs to be updated for CMake. This is my first step at it. Not all changes are done, but this may be a good start.
The standalone instructions are slightly updated, but may not be accurate and will need to be updated later on.
All of the makefile "options" still need to be sorted.
List files for multiple games in a single client-config.json file so
that com_basegame argument can pick different game data.
Use ioquake3.html?com_basegame=demoq3 (or tademo) to run the Quake 3 or
Team Arena demo. They require new QVMs from baseq3/missionpack to run.
Modify the client HTML file when copying it to the build directory to
apply current CLIENTBIN and BASEGAME. It always loads engine/data from
the current directory (no need to try to locate the build directory).
This mainly targets OpenGL ES 2.0 but it also supports compiling GLSL as
ESSL 3.00. It's missing support for framebuffer objects which should be
possible on ES 2. (Though using renderbuffers instead of textures.)
opengl1 cvars that are not supported will display a message and disable
the cvar. This has not been reviewed for new opengl2 cvars. Enabling
cvars may cause rendering issues. Some of the broken cvars may be
possible to support using OpenGL ES 3 features.
The game displays okay with the default cvars.
Update mingw and macOS SDL libraries to 2.24.0. (MSVC .lib files and
Xcode project haven't been updated.)
There is now a separate SDL dylib for macOS Universal Binary 1 and 2
because SDL 2.24.0 dropped support for macOS 10.6 (which is last to
support x86). Documentation says SDL 2.24.0 also dropped macOS 10.7
and 10.8 too. So UB2 is now 10.9 or later while 10.5 to 10.8 live in
UB1.
Compiled using osxcross with macOS 11.3 SDK. Ran "strip -x" on Windows
and macOS libraries. Ad-hoc signed dylib using PyOxidizer rcodesign to
fix digest checksums after strip.
Removed some language about the old mailing list, pointed to forums,
and more accurately to the
wiki, updated reference to SDL.
Zardoz speaks to you, His chosen ones.
A built-in GNU Make rule causes code/tools/lcc/lburg/gram.y to replace
gram.c if gram.y has a newer modified time. This causes git diff to
pick up changes to gram.c, which seems to have been manually modified
to fix warnings and may vary by Yacc used to create it. It also
requires installing a program to generate a file that already exists
in a usable state in the code repository.
So replace the built-in rule so it is only used if USE_YACC is 1
(defaults to 0). The Yacc executable name can be overriden using
`make YACC=yacc` like before.
I preferred to touch gram.c instead of installing Yacc because of the
problems it causes. It doesn't really seem like a good idea to recommend
others do that instead of disabling Yacc the Makefile though.
