Description bergerkos 2018-12-29 21:53:22 UTC
When I'm using the Makefile fields "USE_GCC=yes GCC_COMMAND=/usr/local/bin/gcc8" in my port's Makefile the resulting packages installs the specified gcc compiler package as a dependency.

However, the Porter's Handbook at https://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook/makefile-depend.html explicitly mentions the meaning of the "USE_GCC=" optiona as:

The port requires GCC (gcc or g++) to build. [...]

To build, it says, and adds nothing about installing it together with the compiled port package. In reality, though, this usage ends up in the gcc-$version package being installed along with the port itself. The only way to avoid this currently is to only specify gcc in BUILD_DEPENDS.

What is it? Inconsistency in the documentation? Or a bug in the ports building framework?

Technically a documentation issue. The current documentation is not incorrect, it is just not explicitly complete, mentioning also the fact that its a RUN_DEPENDS too

The ability to specify gcc as a build *only* dependency is being handled in bug 211154, with workarounds in ports in the meantime taking the form of something like ports r464059 (removing gcc from RUN_DEPENDS)

  Note that USE_GCC is a build and a run-time dependency.
