Hi, everyone there:
I need to build gcc with a different vendor string, eg.
x86_64-vendor-linux. Now i have a gcc as x86_64-redhat-linux, how can
I do that?
As far as i know, in the native build case, the new gcc will be
'x86_64-redhat-linux'. If I specify --target=x86_64-vendor-linux, the
build will become a cross build. It seems that I am building a cross
compiler, which is not the case. Since the only difference is the
'vendor' part.
Is there a guide about how to build gcc with different vendor string
in native build way?
Did you try specifying --build instead of --target?
Yes, I have specified --build, --host and --target, where --host euqals
--target. But, it seems that some environment variables, such as LD, AS,
AS_FOR_TARGET, LD_FOR_TARGET are also need to be override. This time,
build goes much more further, but faild with:
../../../../gcc-4.6.2-20111027/libgcc/../gcc/libgcc2.c:1809: warning:
implicit declaration of function ‘__builtin_huge_valq’
../../../../gcc-4.6.2-20111027/libgcc/../gcc/libgcc2.c:1809: error: size
of array ‘compile_type_assert’ is negative
In normal build, this error can not happen. So, it seems there is also
something more to do .
