Upon upgrade to latest build I found chromium does not start up because environ external definition could not be found. While really the C library containing the symbol is on the system because a simple C program compiles, links and runs printing the environment successfully.
This is the runtime linkage error:
ld-elf.so.1: /usr/local/lib/libglib-2.0.so.0: Undefined symbol “environ”
When trying to rebuild port compilation fails due not finding appropriate x86intrin.h:
…/…/third_party/angle/src/common/platform.h:91:10: fatal error: ‘x86intrin.h’ file not found
which is located as follows upon GCC8 installtion from pkg:
Even when forcing to find it by creating symlink compilatin fails because a bunch of intrinsics are not declared.
