ncpp is not using the right compiler or flags

Priority: Normal Milestone:
Component: ports Version: 2.7.1
Keywords: Cc:
Port: ncpp

Description

ncpp is not using the right compiler or flags therefore it fails to build on older systems that require those flags.

The port makes some effort to manually set build args for the compiler to use, but then overwrites those args with others. It doesnt seem to have any code to use the right flags.

Using the makefile 1.0 portgroup can help you use the right compiler and flags.

I tried to set it. I'll see what I can do. I have zero interest in ancient operating systems though.

Please do still have an interest in using the right compiler and flags, however. Doing so enables many MacPorts capabilities, only one of which is support for older operating systems.
