Version discovery from git not working in tests

[sannant]

Not sure this is relevant once SurfaceTopography is installed properly in devel version, but the following line will raise an error if the tests are run in the test subdirectory.

I think a better option would be to call git and check that the package name is SurfaceTopography

Hi @sannant - can you check whether this is still the case in master. Version discovery now explicitly checks for those directories to exist.

I saw changes in Discoverversion that address this.

However I have issues testing this because I have errors when building with meson.

meson setup build
cd build
meson compile
meson install

c/meson.build:10:16: ERROR: 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.

A full log can be found at /home/asanner/Repositories/SurfaceTopography/build/meson-logs/meson-log.txt

Hi @sannant - place your venv outside the source folder and this works.

The c-extension module is including numpy's headers. If you have a venv in the source directory those headers are in the source directory and Meson does not like this.

PS: I am planning to move to the whole codebase to pybind11 which fixes this, but this won't happen within the next weeks.
