Code:

bash-5.1$ cmake -S src -B build
CMake Warning (dev) in CMakeLists.txt:
No project() command is present. The top-level CMakeLists.txt file must
contain a literal, direct call to the project() command. Add a line of
code such as

project(ProjectName)

near the top of the file, but after cmake_minimum_required().

CMake is pretending there is a "project(Project)" command on the first
line.
This warning is for project developers. Use -Wno-dev to suppress it.

i think about "build from source error"

The Steam version is listed as "PLATINUM." https://www.protondb.com/app/1241950

Have you tried the Slackbuild? https://slackbuilds.org/repository/1...search=warzone

i think about "build from source error", src is preferred for Slackware.

The Slackbuild on SBo DOES build from source. Also the official warzone 2100 source is here: https://github.com/Warzone2100/warzone2100/releases as are the compile instructions. The official site is: https://wz2100.net/

Add you didn't consult the build docs since you are using the wrong cmake command line.

Based on the build instructions, you should do something like the following once in the source code directory:

Code:

mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX:PATH=~/wz/install -GNinja ../warzone2100
cmake --build . --target install

Or you could just follow what's in the SlackBuild:

Code:

mkdir -p build
cd build
  cmake \
    -DCMAKE_C_FLAGS:STRING="$SLKCFLAGS" \
    -DCMAKE_CXX_FLAGS:STRING="$SLKCFLAGS" \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_INSTALL_MANDIR=/usr/man \
    -DCMAKE_INSTALL_BINDIR=games \
    ..
  DESTDIR=$PKG cmake --build . --target install
cd ..

Try running the SlackBuild (ponce doesn't have any modifications for it in his repo) and see if you get any errors there.
