running bootstrap.sh fails

hi
I try to install Luax on my mac (macos 14.5 ), here are the errors I get when running ./bootstrap.sh. Looks like something isn't found in my PATH


sh ./bootstrap.sh

Hello,

I think the problem is the stat command in macos, its output may differ from linux.

Could you please run these commands:

LC_ALL=C gstat tools/bang.luax
LC_ALL=C gstat -c '%s;%Y;%X;%W;%F;%f' tools/bang.luax
LC_ALL=C stat tools/bang.luax
LC_ALL=C stat -c '%s;%Y;%X;%W;%F;%f' tools/bang.luax

I previously had to use gstat on macos since the stat command does not work as on linux. You can also check that gstat is installed (the error message could be more explicit...)

I'm afraid that installing gstat won't be enough and some other commands may fail when building luax on non linux OS.
In this case, you can download binaries from https://cdelord.fr/pub#luax-light

_fs.lua should be rewritten to handle the case of macos (well, my assumption that macos is like linux is obviously wrong...)

Can you try to build the dev branch? It has been modified to use the default stat command of macos.

LC_ALL=C stat tools/bang.luax

From all those commands this is the only one that yields no errors

LC_ALL=C stat tools/bang.luax

oops, the new dev branch should work better...

yes, thank you, now it worked and I now have a functioning luax binary under

.build/dist/macos-x86_64/bin/luax

really cool!

just a note: it created also the artefacts for the other platforms (linux and windows), this is not really needed, I think most users just want their binary native to the host platform

Thanks for testing ;-)

If you just want to compile LuaX for the host you can just run ./bootstrap.sh clang. It requires clang and will just compile luax without cross-compilation capabilities.

Ok, I've tried that but somehow I get errors:

You may have an older version of clang. You can try to compile without strict compiler checks with ./bootstrap.sh clang lax (warnings will be ignored)

I'm glad bootstrap.sh is now working on macOS, thank you. To make ninja build also working on macOS you need to change

luax/tools/bang.luax

Line 1048 in 2dad970

command = { "install -v -D -t", "$${PREFIX:-$prefix}"/target_name, "$in" },

to command = { "install", "$in", "$${PREFIX:-$prefix}"/target_name },.

@KernelKinetic Thanks, I've fixed bang and luax to be able to install files on macos.

Thank you, works perfectly. Also thank you for your work in luax, nice tool!
