The reason of not supporting arm Linux.

[leaf-potato]

The official website document states that GreptimeDB only supports amd64 Linux. As far as I know, rust supports cross-platform and GreptimeDB can run on Mac M1. When I compile GreptimeDB in the Ubuntu virtual machine installed on Mac M1, the compilation fails. I am curious about the reason.

Try to manually delete these two lines, and re_compile.

GreptimeDB is definitely can be built on ubuntu, both arm64 and amd64. We know it because we release the binaries. The documents are wrong, would you kind enough to submit a PR? You can paste the compile errors here, let's try to figure out the reason.

Try run cargo clean before build.

It seems that the cause of the build error is that an incorrect linker is specified.
aarch64-linux-gnu-gcc is a cross compiler for ARM64 target. If specify linker as aarch64-linux-gnu-gcc on the arm linux platform, it obviously cannot be found and go wrong.

aarch64-linux-gnu-gcc is installed in the system.

My quick guesses are ld got killed by OOM. Try cargo build with "-j 4".

I found the reason! The linux installed in the virtual machine only has 8g of memory allocated and the program was killed at the linking stage. I changed the configuration to use the mold linker with no problems.

The solution was found in this discussion:

waynexia: 确保你有足够的内存。或者尝试使用 mold，它在链接阶段需要更少的内存。

We provide pre-built arm64 binaries for Linux. https://greptime.com/download

I found the reason!

Great!

aarch64-linux-gnu-gcc is installed in the system.

It looks like the Ubuntu installed on the Mac M1 is an x86 architecture. 😅 I thought it was an arm64 architecture before.
