Unable to locate suitable (>=1.7.1) PDAL library.(MacOS m4)

[tangelll]

Hi,

I am trying to build the project on a MacBook M4 with Python 3.12.12, but I am unable to bypass the following error during the configuration stage:

error: *** Unable to locate suitable (>=1.7.1) PDAL library.

Even though PDAL is installed via Homebrew and the paths are correctly specified, the build process fails to detect the library. Any guidance on how to resolve this for the M4 architecture would be appreciated.

Configure depends on pkg-config to find the necessary compilation information to build against PDAL. If you build GRASS using dependencies in a distribution system like Homebrew (but not as part of that system) you may need to give a nudge to help the configuration to find certain things.

pkg-config is looking for *.pc files, you need to find out where the pdal.pc is located (in MacPorts it is /opt/local/lib/pkgconfig/pdal.pc). Then something like:

export PKG_CONFIG_PATH="[path-to-directory-containing-pdal.pc]:${PKG_CONFIG_PATH}"

might work out your problem.
