atlas @3.10.2: error: implicit declaration of function 'dgeqlf_' is invalid in C99

[gsarrouh]

I am trying to install Source Extractor v.2.19.5 using the terminal command: >> sudo port install source-extractor

Three dependencies are required: i) atlas; i) fftw-3; iii) fftw-3-single

When I execute the command i get the following output:

gsarrouh$ sudo port install source-extractor

I really have no idea why altas is failing the build stage, but I cannot use a different software package other than Source Extractor for my work so I really need this to work!

Thanks for your help in advance,

The issue is that implicit function declarations used to be considered warnings, but are now considered errors with Xcode 12. The canned response is to downgrade to Xcode 11.x to avoid the errors until MacPorts addresses them.

Existing upstream ticket regarding these implicit function declarations (no feedback yet from developer): ​https://sourceforge.net/p/math-atlas/support-requests/1082/
