Termux can not use emcc

[hyfhaozero]

Version of emscripten/emsdk:
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 4.0.1 (89ce854)

Failing command line in full:
emcc: warning: cannot check node version: [Errno 2] No such file or directory: '/data/data/com.termux/files/home/emsdk/node/20.18.0_64bit/bin/node' [-Wversion-check]

Full link command and output with -v appended:

Everything is okay before i run emcc,and i think it may was caused by different architectures(My system: arm64)

What happens if you try to run on of the executable directly, i.e. node or clang?

Can you run /data/data/com.termux/files/home/emsdk/node/20.18.0_64bit/bin/node --version?

What does file /data/data/com.termux/files/home/emsdk/node/20.18.0_64bit/bin/node say?

What does ldd /data/data/com.termux/files/home/emsdk/node/20.18.0_64bit/bin/node say?

Looks like you are somehow missing that needed shared libraries to run node.

What does file /data/data/com.termux/files/home/emsdk/node/20.18.0_64bit/bin/node say?

What does file /usr/bin/ls say?

What linux distro are you using?

~/emsdk $ file /data/data/com.termux/files/home/emsdk/node/20.18.0_64bit/bin/node

~/emsdk $ file ~/../usr/bin/ls

And I use termux so there's no any linux distro is used by me

[sbc100]

I have no idea want termux is.

What does file /data/data/com.termux/files/home/../usr/bin/ls say? The reason I'm asking is that it seems that maybe you have install the arm64 version of emsdk inside and environment that is not setup for arm64. At least it seems to be missing all of the core DLLs.

[sbc100]

It looks like you might not have the glibc libraries installed in termux. I see some instructions for getting starting with glibc packages here: https://github.com/termux/glibc-packages. Note that emsdk binaries are all linked against glibc and require glibc .so files it be available at runtime.
