cc-fullversion
|
||||
cc-fullversion is useful when the exact version of gcc is needed.
|
||||
One typical use-case is when a specific GCC version is broken.
|
||||
cc-fullversion points out a more specific version than cc-version does.
|
||||
|
||||
Example:
|
||||
#arch/powerpc/Makefile
|
||||
$(Q)if test "$(cc-fullversion)" = "040200" ; then \
|
||||
echo -n '*** GCC-4.2.0 cannot compile the 64-bit powerpc ' ; \
|
||||
false ; \
|
||||
fi

In this example for a specific GCC version the build will error out
