C/C++ runner fails: cannot open output file .../use/tmp/_acs_run (should be usr/tmp)

[Dankgowndove]

Description

When clicking Run on a .c or .cpp file, the linker fails with:

ld.lld: error: cannot open output file /data/data/com.acside/files/use/tmp/_acs_run: No such file or directory
g++: error: linker command failed with exit code 1

The temporary output path uses use/tmp instead of the correct usr/tmp. The directory use does not exist, so the linker cannot create the output file.

Steps to reproduce

1. Open or create a .c or .cpp file.
2. Click the Run button.
3. The linker fails with the error above.

Workaround

Creating a symlink from use to usr fixes the issue:

cd /data/data/com.acside/files
ln -s usr use

After that, running .c and .cpp files works normally.

Suggested Fix

• Use usr/tmp instead of use/tmp.
• Or ensure the use/tmp directory exists before running the compiler.
• Better: use $PREFIX and $TMPDIR, e.g. ${TMPDIR:-$PREFIX/tmp}/_acs_run.
