Nice name, but the sm command on OpenSuse and Ubuntu refers to screen-message.
the cxx tool fails to handle CXX or CXXFLAGS environment variables correctly,
even for a hello.cpp
Examples:
CXX="g++ -DHELLO_FROM_CXX" cxx
CXX="g++" CXXFLAGS="-DHELLO_FROM_CXXFLAGS" cxx
Instead of building the example, scons prints the scons commandline help.
When avoiding a "-D" in CXXFLAGS and using a "-I" instead (with a script for CXX),
the failure is different:
Example with "scriptname":
CXX="scriptname" CXXFLAGS=" -I/$HOME/dummy_include_dir " cxx
scriptname -o hello.o -c -std=c++20 -O2 -pipe -fPIC -fno-plt -fstack-protector-strong -Wall -Wshadow -Wpedantic -Wno-parentheses -Wfatal-errors -Wvla -Wignored-qualifiers hello.cpp
sh: 1: scriptname: not found
*** [hello.o] Error 127
Using export makes no difference:
export CXX="scriptname"
export CXXFLAGS=" -I/$HOME/dummy_include_dir "
cxx
scriptname -o hello.o -c -std=c++20 -O2 -pipe -fPIC -fno-plt -fstack-protector-strong -Wall -Wshadow -Wpedantic -Wno-parentheses -Wfatal-errors -Wvla -Wignored-qualifiers hello.cpp
sh: 1: scriptname: not found
*** [hello.o] Error 127
$ cxx export
make: *** No rule to make target 'export'. Stop.
Hello Alexander,
I got a Python warning and some Error on MacOS Sonoma (on all Projects). Here an Example:

Perhaps something with the new Python version?
