make seems to produce debug version of odin, but just after that: paul@fedora:~/Odin$ make ./build_odin.sh debug

Also happens when trying to run hello.odin:

paul@fedora:~/myodin/hello$ ls
hello  hello.odin
paul@fedora:~/myodin/hello$ rm hello
paul@fedora:~/myodin/hello$ odin run .

LLVM/clang 18 is not supported yet

I have tried on an other of my HD with Kubuntu. Previously this morning, was on 23.10, and was working fine.

Now after update to 24.04 Beta... I got:

paul@rafulos:~/Odin$ make

I realize I need to test with an older version of clang.

Did:

sudo apt remove clang
git clean -dfx
paul@rafulos:~/Odin$ CC=clang++-17 make
./build_odin.sh debug

paul@rafulos:~/Odin$ whereis clang++-17

Is there an easy web to force the use of clang++-17 ?

With:

that works! So it really seems to be linked to the use of clang version 18.

I have been able to make Fedora 40 works with odin by:

git clean -fdx

paul@fedora:~/Odin$ ln -s /usr/lib64/llvm17/bin/clang  ~/.local/bin/clang
then make

odin then report "badly" version 18.1.1
