Re: USE_PKGSRC_GCC and circular dependency

[Zhiwen Zheng <zhiwen%40701.xyz@localhost>]

Thanks, it helped, now build starts without circular dependency. 
My understanding of USE_PKGSRC_GCC was wrong, I expected gcc will get bullt and all other packages get built using
the newly created gcc automatically.
I am preparing the package repo for my self-made illumos distribution, seems like I need two versions of mk.conf.
First, use "USE_NATIVE_GCC=yes;GCCBASE=path_to_native_gcc;" to build gcc and its dependencies.
Then, remove USE_NATIVE_GCC and GCCBASE from mk.conf and add "GCC_REQD;USE_PKGSRC_GCC=yes;USE_PKGSRC_GCC_RUNTIME=yes",
and rebuild gcc's dependences. 
This way all pacakges will not link with the native gcc runtime. Am I right?



Below is the mk.conf I used.
