Libftdi1 fails with option DOCS=on with: [25/45] cd /ram/usr/ports/devel/libftdi1/work/libftdi1-1.4 && /usr/local/bin/cmake -E make_directory /ram/usr/ports/devel/libftdi1/work/libftdi1-1.4/doc && /usr/local/bin/doxygen /ram/usr/ports/devel/libftdi1/work/libftdi1-1.4/Doxyfile ninja: build stopped: subcommand failed. ===> Compilation failed unexpectedly. Try to set MAKE_JOBS_UNSAFE=yes and rebuild before reporting the failure to the maintainer. *** Error code 1 compiles fine with DOCS=pff on 10.3amd64
I would say set DOCS by default off with a comment like "Does not compile on 10.3".
same on 11.1. Maybe related https://trac.macports.org/ticket/53242 Over to port maintainer for evaluation
will commit shortly *** This bug has been marked as a duplicate of bug 219022 ***
