This is the preferred use of USE_GCC. # It uses the canonical version of GCC defined in bsd.default-versions.mk. # # If your port needs a specific (minimum) version of GCC, you can easily # specify that with a USE_GCC= statement. Unless absolutely necessary # do so by specifying USE_GCC=X+ which requests at least GCC version X. # To request a specific version omit the trailing + sign. # # Optionally comma-separated arguments follow the version specifier. # Currently we support: # build ... which adds GCC as a build dependency (BUILD_DEPENDS) only. # # If no arguments are specified, GCC is added as both a build dependency # and a run time dependency. # -# (USE_GCC=any is deprecated, must not be used for new ports, and should -# be migrated to USE_GCC=yes or completely removed if possible.) +# (USE_GCC=any is deprecated - and now an odd way to write USE_GCC=yes. +# Do *not* use! It will be removed shortly.) # # # Examples: # USE_GCC= yes # port requires a current version of GCC # # as defined in bsd.default-versions.mk. # USE_GCC= 11+ # port requires GCC 11 or later. # USE_GCC= 9 # port requires GCC 9. # USE_GCC= yes:build # port requires a current version of GCC at # # build time only. # USE_GCC= 10:build # port requires GCC 10 at build time only. # USE_GCC= 11+:build # port requires GCC 11 or later at build # # time only. # # If you are wondering what your port exactly does, use "make test-gcc" # to see some debugging.
