errormsg = '''Tried to form an absolute path to a dir in the source tree.

You should not do that but use relative paths instead, for
|
|
|
|
|
directories that are part of your project.
|
|
|
|
|
|
|
|
|
|
To get include path to any directory relative to the current dir do
|
|
|
|
|
|
|
|
|
|
incdir = include_directories(dirname)
|
|
|
|
|
|
|
|
|
|
After this incdir will contain both the current source dir as well as the
|
|
|
|
|
corresponding build dir. It can then be used in any subdirectory and
|
|
|
|
|
Meson will take care of all the busywork to make paths work.
|
|
|
|
|
|
|
|
|
|
Dirname can even be '.' to mark the current directory. Though you should
|
|
|
|
|
remember that the current source and build directories are always
|
|
|
|
|
put in the include directories by default so you only need to do
|
|
|
|
|
include_directories('.') if you intend to use the result in a
|
|
|
|
|
different subdirectory.
|
|
|
|
|
|
|
|
|
|
Note that this error message can also be triggered by
|
|
|
|
|
external dependencies being installed within your source
|
|
|
|
|
tree - it's not recommended to do this.
