The linux executable is x86 only, I received this error on trying to run it on a raspberry pi

Failed to execute process './v'. Reason:
exec: Exec format error
The file './v' is marked as an executable but could not be run by the operating system.

Trying to build from source bugged out for some reason and tried tcc.exe on a linux machine

==================
C error. This should never happen.

If you were not working with C interop, this is a compiler bug, please raise an issue on GitHub:

the file is only called tcc.exe, it is still an ELF executable
the problem might be that it downloaded the x86_64 version of tcc

Will installing tcc from my system package manager prevent the installer from doing this.

I also already have gcc and g++ installed and on PATH as well

[spaceface777]

try setting the env variable VFLAGS to -cc gcc.

Not really - it'll make tcc actually run, but our tcc version contains patches that are most likely not in the system package so you'll hit other errors instead.

make: *** [Makefile:86: all] Error 1

A different error with the environment variable set and using the weekly release version.

What I noticed:

• make: *** [Makefile:86: all] Error 1 that it isn't identifying my machine correctly.
• And from cd ./thirdparty/tcc && git clean -xf && git pull --quiet it seems like it's still trying tcc but it's not an exe now

[medvednikov]

we will provide arm64 tcc builds soon
