Unable to link openal during compilation

gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0
cmake version 3.19.2

And what about changing OFF to FALSE ?

@nbohr1more, also try this: add the following lines at the end of the "include" commands sequence:

include(CheckPIESupported)
check_pie_supported()

It is quite likely that this command sets up a variable, and if it is not called, then PIC setting is simply ignored.

Do you have CMake newer than 3.14?
It should pass -no-pie automatically to linker.

My version is 3.20, and I still need to pass "-no-pie".

If people will uninstall + install the game every year, they will generate unnecessary traffic spikes.

The program is intended to create packages. The download will be from the server containing those packages.

TDM installation is designed as user-only: it does not need admin rights, and is installed to one directory. Trying to turn this into system-wide installation is fragile and pointless.

What it does is recreating the game in the user home folder. But the pk4 files, instead of being copied, are linked to a system wide directory. So one folder with those pk4 serve all the users in the system, keeping each individual user installation quite small and isolated.

Try to change this line OFF to FALSE in the line with POSITION_INDEPENDENT_CODE

Try to add line after minimum required version: cmake_policy(SET CMP0083 NEW)

Post your GCC version.

Changing OFF to FALSE works.

I changed FALSE back to OFF and added these lines and it completed the compile but I think I need to remove the previous executable to be sure?

The engine can repack core pk4 files in principle.
I think it won't happen for your installation, just keep in mind that this way is not reliable.

I don't think it is OFF vs FALSE.
Cmake has Off/False/0/No. It would be hell if they were not equivalent.

I have committed CheckPIESupported to SVN trunk.
I hope it works for you out-of-the-box now.

Ok, changed it again, and now it seems to work (at least on appveyor).

Not only CheckPIESupported is necessary, but it must also be put after "project" command.
