I have a meson project on the path /home/$user/foo/bar/project. I want to set a variable sys_root in a cross_compile.txt file. I don't want to hard code the path in case my project moves to another directory.

I don't want sys_root = /home/$user/foo/bar/project/prefix. I want i sys_root = project-dir/foo/bar/prefix

What is the variable for the current directory with the cross_compile.txt in case it is in the same directory with the meson.build file?

CodePudding user response：

The closest thing that currently exists is the [constants] section of the machine files, you can write something like:

[constants]
root_dir = "/home/$user"

and

[properties]
sys_root = root_dir   "/project_dir/..."

And layer them together with meson setup builddir --cross-file contants.ini --cross-file main.ini
