[Solved] How to replace -D_FORTIFY_SOURCE=3 with -D_FORTIFY_SOURCE=2

Hi, I'm working on a pkgbuild for the intel NPU driver (for the sake of packaging; I don't have the hardware for testing)

the last issue I'm having is that it fail with -D_FORTIFY_SOURCE=3 while with -D_FORTIFY_SOURCE=2 build

How can I replace or change it?

Something along the lines of

export CFLAGS="${CFLAGS/D_FORTIFY_SOURCE=3/D_FORTIFY_SOURCE=2}"

in the PKGBUILD should work.

That dind't work but I found a solution while casually looking into openvino pkgbuild which have the same problem

export CFLAGS="${CFLAGS/-Wp,-D_FORTIFY_SOURCE=?/}"
export CXXFLAGS="${CXXFLAGS/-Wp,-D_FORTIFY_SOURCE=?/}"

That removes it altogether, which isn't what you want.

OK, got it to work extending WorMzy suggestion to CXXFLAGS, this is mostly written in c++, didn't think about it at the first try

export CFLAGS="${CFLAGS/D_FORTIFY_SOURCE=3/D_FORTIFY_SOURCE=2}"
export CXXFLAGS="${CXXFLAGS/D_FORTIFY_SOURCE=3/D_FORTIFY_SOURCE=2}"

Edited with the last suggestion

You should change the instance of 'CFLAGS' to 'CXXFLAGS' in the second line, otherwise you'll lose any c++-specific flags (like '-Wp,-D_GLIBCXX_ASSERTIONS').
