To Reproduce

Clone the git repository:

git clone --recurse-submodules https://github.com/ezQuake/ezquake-source.git

Switch to ezquake-source path:

cd ~/ezquake-source/

Initialize/update git submodules:

git submodule update --init --recursive --remote

Run the compilation (replace 5 with the number of cpu cores you have +1):

make -j5

You can add -jN as a parameter to make to build in parallell. Use number of cpu cores plus 1 (e.g. -j5 if you have a quad core processor).

Copy the compiled binary to your Quake folder, on 64bit linux the binary will be called ezquake-linux-x86_64.

Expected behavior
binary ezquake-linux-x86_64

Try to remove from src/sv_mod_frags.c:181:51: pcre2_substring_list_free((const PCRE2_UCHAR8**)buf); substring const: pcre2_substring_list_free((PCRE2_UCHAR8**)buf); and build again.

@VVD Thanks a lot! Build done.

[12sunflowers]

@VVD sorry have yet questions

again make clone git with no editing src/sv_mod_frags.c :181:51:

pcre2_substring_list_free((const PCRE2_UCHAR8**)buf); substring const: pcre2_substring_list_free((PCRE2_UCHAR8**)buf);

and its build good with no errors, why?

game working well, but what this mean at console?

home:[freeartist-artix]:~/Downloads/ezquake-source$ ./ezquake-linux-x86_64
**Error: Couldn't load gfx/palette.lmp**

This is typically caused by being unable to locate pak0.pak.
Copy pak0.pak into 'id1' folder, in same directory as executable.

1. Another compiler? Other build options?
2. Read this:

You need file pak0.pak with game data.

Another compiler? Other build options?

Only add to env, do git clone and build again with no errors
export CFLAGS="-march=native -O3"
from advice at nQuake/client-linux#15 (comment)

Read this:

already present at dir with builded bin ezquake-linux-x86_64

home:[freeartist-artix]:~/Downloads/ezquake-source/id1$ ls
id1  pak0.pak  pak1.pak
home:[freeartist-artix]:

and what this mean? i am at old g92 nvidia card with 340.108 driver patched for new kernels

Get nQuake, install it and replace ezquake with just compiled.
