vector warning

edw8 — Wed, 17 Oct 2018 18:45:21 GMT

For several MCUXpresso IDE versions now going back to 10.1.0, I see a bunch of notes in the build output regarding my code including the <vector> header file. This is a C++11 project using vectors. The notes are mostly annoying though suspicious. Seeing that subsequent build toolchain updates in MCUXpresso did not resolve or get rid of these notes, I wanted to ask the MCUXpresso design team about the plan to correct/remove them.

The sample below comes for just one .cpp file. I have a similar set for other .cpp files that include <vector>

Re: vector warning

This warning relates to an ABI compatibility issue between code built with GCC6 and GCC7. As long as you are building all code with the same GCC version, you should be able to ignore, and disable using the "-Wno-psabi" option.

For more information, do an internet search for something like "parameter passing for argument changed in GCC 7.1" which will give numerous hits, for instance: https://gcc.gnu.org/ml/gcc/2017-05/msg00072.html
