libgcc13 @13.2.0: error: expected ')'

[tcwan (TC Wan)]

Running on Sonoma 14.0 on M2 Mini. The build fails with an error, but it is too verbose for me to parse the cause.

The mention of "/opt/local/include/ansidecl.h" may be the relevant bit. The binutils and gdb ports install this file. Do you have either of those installed? If so, try deactivating them (sudo port deactivate binutils or sudo port deactivate gdb), then cleaning libgcc13 (sudo port clean libgcc13) and trying again. Having binutils installed is known to cause some ports to fail to build; I don't recall if gcc is one of them.

Yes, I had gdb installed. Thanks, the workaround managed to solve the error when building libgcc13.
