"unable to execute command: program not executable" on Windows
MyStupidUserName opened this issue · comments
llvm-mingw-20240404-msvcrt (both i686 and x64builds) for Windows fails with an error when using gcc.exe, g++.exe or clang.exe to perform a single-step compile/link.
gcc.exe hello.c
generates the error "clang-18: error: unable to execute command: program not executable".
g++ hello.cpp
does the same.
This error also occurs with llvm-mingw-20240320-msvcrt on Windows.
Compiler option -c works to generate a valid .o file.
This 2-step process works to build an executable:
gcc.exe -c sieve.c
gcc -o sieve.exe sieve.o
2-step g++ build works also.
Running as a stand-alone installation, no MSVC.
Running on Windows 7 Pro 64-bit.

Windows 10 here.
For one step you could try:
gcc.exe -o hello.exe hello.c
This sounds weird and surprising. Especially if separate compilation and linking succeeds, but one command to both compile and link fails.
I tested this on a Windows 7 VM, with llvm-mingw-20240404-msvcrt-x86_64, and it successfully compiled and linked with one command, just by executing e.g. gcc hello.c.
Aaaaand... I take it back.
I could not get it to work, no matter what I tried, a few days ago, but now it's all working, using clang.exe, gcc.exe, and g++.exe!
Maybe it's time to restart Windows. Kindly disregard my previous post.
Ok, let's close this one then.
