lua - How to compile srlua?

Question

I made a program today, and I was wondering on how exactly to make it an executable. I've researched and I've came up with using srlua. I've asked this previously, but I usually mess up on the same instruction. I was told to 'compile srlua' While I know exactly what to do right after I compile srlua, I don't know how to compile them right now.

I've gone through a few YouTube tutorials, and I managed to find one but only in Spanish. I was able to slightly follow along until he downloaded a precompiled version of srlua, where the download link is no longer there at the same page he was at.

Would anyone be able to explain what they're trying to say?

You need to tell CMake where the Lua files it needs are.

For me, the Lua includes are in /usr/include/luaX.X, where X.X is your version number, e.g. 5.3. The Lua libraries may be in /usr/lib (with filenames like libluaX.X.so).

If the locations differ for you, you can try find / | grep "lua.h" and find / | grep "liblua".

Once you've located the folder which lua.h is in, and the appropriate library file like liblua5.3.so, you need to add these to the CMakeLists.txt file in the srlua folder. For example, using lua5.3, you might replace this line:

include_directories(${LUA_INCLUDE_DIR})

with this one:

include_directories(/usr/include/lua5.3)

And for the libraries, you might replace this:

target_link_libraries(glue ${LUA_LIBRARIES})
target_link_libraries(srlua ${LUA_LIBRARIES})

with this:

target_link_libraries(glue /usr/lib/liblua5.3.so)
target_link_libraries(srlua /usr/lib/liblua5.3.so)

After this, run cmake ./ in the srlua folder, then run make. srlua should be built.

Note: you may also have to remove the line find_package ( Lua REQUIRED ), it was a false error for me (it only built when I removed that line).
