gmt6 @6.5.0_0+gdal+nonfree+pcre build failure

[dimartino-uc]

I attempted to install gmt6, including its dependencies using the directions in the link below and was unable to do so.

​https://docs.generic-mapping-tools.org/dev/install.html#macos

I have also the log associated with the failure and was hoping to get some isight on the cause of the failure.

I hope I can shed some light on this and provide you with a way forward.

The specific error messages come from the piece of code that is specific to the "New Accelerate Framework" that was introduced in Darwin 22.4 (MacOSX 13.3) and provides lapack to the GMT build.

The GMT build checks for this Darwin version, and if this is larger or equal to 22.4 this snippet of code in gmt_vectior.c is activated. Now since the error suggests that __LAPACK_int is not defined, it would mean that your headers are not compliant with the "New Accelerate Framework" that was introduced in MacOS 13.3. This likely means that you have not recently updated Xcode or the Xcode Command Line Tools. In that case, the header files for the Accelerate Framework would be outdated.

So please check if you are indeed running MacOS 13.3 (Darwin 22.4) or later, and that your installation of Xcode or the Xcode Command Line Tools is recent.

I could not replicate your problem on my system (MacOS 14.2.1, Command Line Tools 15.1). I also checked if installing the macports lapack package made a difference: it did not. The GMT build faithfully took lapack from MacOS' Accelerate Framework.

That was it. Thank you for your assistance.

You're welcome. That closes this ticket then.
