pkgsrc GCC failed to build any packages

["hung.nguyengia" <hung.nguyengia%protonmail.com@localhost>]

Both GCC10 and GCC8.

The GCC10 case:

The GCC8 case:

checking for %lld and %llu printf() format support... ^C*** Error code 1
*** Signal 2
*** Signal 2

(I have to cancel it).

You could see. All of the GCC installed by pkgsrc (lang/gcc10 and lang/gcc8) failed to serve as the compiler for pkgsrc itself. They always fail mysteriously when they are expected to work.

Meanwhile pkgsrc Clang (installed by lang/clang) could serve as the pkgsrc compiler just fine.

It's getting ridiculous with the GCC8 case. I have these on my mk.conf:

#PKGSRC_COMPILER=	GCC
#GCC_REQD=              8
GCCBASE=                /test/pkg1/gcc8
CC=                     /test/pkg1/gcc8/bin/gcc
CXX=                    /test/pkg1/gcc8/bin/g++

You could see the problem here. You have to comment out the two beginning lines, if you don't any port will fail to build with this error message:

ERROR: This package has set PKG_FAIL_REASON:
ERROR: No acceptable compiler found for joe-4.6.
*** Error code 1

Stop.
