So with this patch applied we would get this CFLAGS on sysconfigdata on the
build directory:
'CFLAGS': '-fno-strict-overflow '
'-Wsign-compare '
'-DNDEBUG '
'-g '
'-O3 '
'-Wall '
'-O2 '
'-g '
'-fcanon-prefix-map '
'-fmacro-prefix-map=/build/tmp/work/core2-64-oe-linux/python3/3.13.2/Python-3.13.2=/usr/src/debug/python3/3.13.2
'
'-fdebug-prefix-map=/build/tmp/work/core2-64-oe-linux/python3/3.13.2/Python-3.13.2=/usr/src/debug/python3/3.13.2
'
'-fmacro-prefix-map=/build/path/unavailable/=/usr/src/debug/python3/3.13.2 '
'-fdebug-prefix-map=/build/path/unavailable/=/usr/src/debug/python3/3.13.2 '
'-fdebug-prefix-map=/build/tmp/work/core2-64-oe-linux/python3/3.13.2/recipe-sysroot=

'-fmacro-prefix-map=/build/tmp/work/core2-64-oe-linux/python3/3.13.2/recipe-sysroot=
'
'-fdebug-prefix-map=/build/tmp/work/core2-64-oe-linux/python3/3.13.2/recipe-sysroot-native=
'
'-fmacro-prefix-map=/build/tmp/work/core2-64-oe-linux/python3/3.13.2/recipe-sysroot-native=
'
'-pipe '
'-O2 '
'-g '
'-fcanon-prefix-map '
'-fmacro-prefix-map=/build/tmp/work/core2-64-oe-linux/python3/3.13.2/Python-3.13.2=/usr/src/debug/python3/3.13.2
'
'-fdebug-prefix-map=/build/tmp/work/core2-64-oe-linux/python3/3.13.2/Python-3.13.2=/usr/src/debug/python3/3.13.2
'
'-fmacro-prefix-map=/build/path/unavailable/=/usr/src/debug/python3/3.13.2 '
'-fdebug-prefix-map=/build/path/unavailable/=/usr/src/debug/python3/3.13.2 '
'-fdebug-prefix-map=/build/tmp/work/core2-64-oe-linux/python3/3.13.2/recipe-sysroot=

'-fmacro-prefix-map=/build/tmp/work/core2-64-oe-linux/python3/3.13.2/recipe-sysroot=

'-fdebug-prefix-map=/build/tmp/work/core2-64-oe-linux/python3/3.13.2/recipe-sysroot-native=
'
'-fmacro-prefix-map=/build/tmp/work/core2-64-oe-linux/python3/3.13.2/recipe-sysroot-native=
'
'-pipe',
After replacing buildpaths and DEBUG_PREFIX_MAP on the package directory with
`py_package_preprocess()`:
'CFLAGS': '-fno-strict-overflow '
'-Wsign-compare '
'-DNDEBUG '
'-g '
'-O3 '
'-Wall '
'-O2 '
'-g '
'-fmacro-prefix-map=/build/path/unavailable/=/usr/src/debug/python3/3.13.2 '
'-fdebug-prefix-map=/build/path/unavailable/=/usr/src/debug/python3/3.13.2
'
'-pipe '
'-O2 '
'-g '
'-fmacro-prefix-map=/build/path/unavailable/=/usr/src/debug/python3/3.13.2 '
'-fdebug-prefix-map=/build/path/unavailable/=/usr/src/debug/python3/3.13.2
'
'-pipe',
There are still some 'prefix-map' stuff that is not properly being replaced
because the do_install() task is
doing this sed expression `-e "s,${B},/build/path/unavailable/,g"`. We could
probably move that to
`py_package_preprocess()` and remove DEBUG_PREFIX_MAP entries altogether. I can
put a v2 doing
that if you agree with that.

Apologies, but I don't fully understand what you say. You show how the
entry in sysconfigdata looks before and after without your patch, but
I am not seeing how it looks before and after *with* the patch.
Without it, it's really hard to understand what the problem is, and
how it is being fixed.
