# bsd.gcc.mk - Support for smarter USE_GCC usage.

|
# For port developers:
|
||
|
|
# If your port needs a specific version of GCC, you can easily specify
|
||
|
|
# that with the "USE_GCC=" statement. If you need a certain minimal version,
|
||
|
|
# but don't care if about the upperversion, just the + sign behind
|
||
|
|
# the version.
|
||
|
|
#
|
||
|
|
# For example:
|
||
|
|
# USE_GCC= 3.3 # port requires gcc 3.3 to build with.
|
||
|
|
# USE_GCC= 3.1+ # port requires gcc 3.1 or later to build with.
|
||
|
|
#
|
||
|
|
# If you are wondering what your port exactly does, use "make test-gcc"
|
||
|
|
# to see some debugging.
