Build failed to compile on Raspberry Pi 4, with
clang: error: the clang compiler does not support '-march=native'
The build script checks $OS_ARCH for `arm64` to distinghuish between ARM
and X64 architecture. However on Raspberry Pi, the `uname -m` command
reports `aarch64` rather than `arm64`.
This change updates the EXTRAFLAGS of the `release-native` target to
check for both - `arm64` and `aarch64`.
1. if ran without choosing a build type (just `make` or
`build_odin.sh`), print out a message about it being a debug build
2. Add `make release-native` alongside `make release_native` to align
with `build_odin.sh release-native`
3. Only run the demo if it is a debug build (just like `build.bat`)
We copy the LLVM shared object when building Odin on Linux. Contrary the comment in `build_odin.sh`,
this is unnecessary, and Odin can be compiled and itself compile things just fine without this step.
This is then packaged up at release and leads to #4019 and #4033. The Linux release builds are built
on Ubuntu and not strictly supported on other Linux distributions. Building from source is preferred.
Got a report on Discord that the current way didn't work for a user,
this change did work and I confirmed with @harold-b (who initially added
this) that it also works for them and is actually a better way.
A few reports of either people not having this clang++ or having it but
it not finding system headers. On top of that, the reason we added this
in the first place was a bug that surfaced on clang-18 which we've since
fixed.
Order will now be clang++ from path, then the llvm bindir clang++, then an
error.
This can all still be overwritten with `CXX=blah make` like before.
This patch makes Odin to compile on Haiku which is a good first step.
Now, all that's needed to do is to figure out how to do futexes, which
I am blaming for the program crashing.
