fatal error: 'stdarg.h' file not found

I created a new lc environment and built it using the README.

I am getting the following error on macOS:

$ ./src/bin/lc integration_tests/array_09.cpp

I will try to share the zshrc configurations tomorrow morning. Its picking the wrong set of headers. That’s all. Path related issue.

[czgdp1807]

Oh I see.

[czgdp1807]

Use the installed lc and not the one from src/bin/lc. Installed one goes to CONDA_PREFIX/bin. Add it to PATH and everything should work fine. These are all path related issues. Also, pass, -I$CONDA_PREFIX/include in —extra-arg.

I see. When you install it, it works!

lc integration_tests/array_09.cpp

That means one must always install using "make install", until we fix all these path issues (here is another one: #32).
