Component: ports Version:
Keywords: Cc:
Port: gcc-devel

Description (last modified by ryandesign (Ryan Carsten Schmidt))

the gcc/g++ that come with gcc-devel are unable to find the system headers due to a mismatch in the name of the SDK: 

~/tmp/c++>gcc -v -v -v str.c -o str
Using built-in specs.

We have no good plan for this just yet.

We have up until now tried to use an SDK that matches the system version we are building on, but that plan no longer seems viable.

While we debate the alternative, you will have to rebuild gcc (and many other ports) from source to pick up the name of your current SDK.

And whenever you upgrade your Xcode / CLTs, the same thing will happen.

We may decide to bake in MacOSX.sdk instead of a system-specific sdk, but this is still under debate.
