First off, to set expectations... this project is essentially unmaintained. I'm giving it a home on my GitHub, but I haven't used it in years, and never really used it that much.

The issue here is clearly that gcc is treating what is intended to be a path as an argument, because it starts with a dash. Many Unix commands will blow up in the same circumstances. There is a convention, with GNU tools at least, to support -- to end argument parsing. But that only works if the last arguments are non-options (e.g. files).

It's this that's the problem: -iframeworkwithsysroot /System/Library/Frameworks/-5185-11ef-9a51-9ab6d782fe32/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.0.Internal.sdk/System/Library/PrivateFrameworks/ -5185-11ef-9a51-9ab6d782fe32/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX15.0.Internal.sdk/System/Library/Frameworks/ That "iframeworkwithsysroot" feels like something that is Apple proprietary, but I don't know for certain.

I'm not really sure what this project could even do about it. src/Makefile.am is pretty barebones: https://github.com/rlaager/docsis/blob/master/src/Makefile.am

The problem arises from the net-snmp-config --cflags which is using the MacOS net-snmp package.

you can check with:

/usr/bin/net-snmp-config --cflags

which generates the gibberish.

I have installed the brew install net-snmp which gives us nice cflags. But it is (and should be) contained within /opt/homebrew/opt/net-snmp/. See:

/opt/homebrew/opt/net-snmp/bin/net-snmp-config --cflags

Now to the part I have no clue and thus did a hacky thing: Tell the autogen to use this bin.

So I modified (right after cloning) the configure.ac net-snmp path by prefixing before $PATH (line 56/57 in configure.ac is now:

AC_PATH_PROG([NETSNMP_CONFIG], [net-snmp-config], [/usr/libexec/net-snmp-config],
                   [/opt/homebrew/opt/net-snmp/bin:$PATH:${prefix}/bin:${exec_prefix}/bin:/opt/net-snmp/bin:/usr/local/bin:/usr/bin])

then do:

./autogen.sh
./configure
make
make install

and you should be good to go.

@rlaager maybe you can help us to do this e bit more elegantly?
