Troubles compiling llvm

Steven Truppe
Hi everyone,

i'm trying to compile llvm with ExternalProject_Add and get the
following error:

-- Installing: /usr/lib/ocaml/llvm/llvm.mli
CMake Error at bindings/ocaml/llvm/cmake_install.cmake:49 (file):

   to "/usr/lib/ocaml/llvm/llvm.mli".

I followed the instructions from llvm.org but i still get this error
during installation (the build process works fine but during install i
get this error).


best regards!

Hi Steven,

I would assume the problem is that you do not have write permissions for /usr/lib. You either need to give yourself the appropriate rights, our run the build as root (which is probably a very bad idea). If you don't want to actually install to /usr/lib, you can pass a different CMAKE_INSTALL_PREFIX to the build via ExternalProject_Add's CMAKE_ARGS argument, i.e. something like

ExternalProject_Add(xxx
  ...
  CMAKE_ARGS -DCMAKE_INSTALL_PREFIX=<where to install LLVM to>
  ...

This sounds like you need access rights, you probably need to use:

$ sudo make install

(unless the file doesn't exist, but I assume this would be another error
message)

To answer myself:

I just saw that you already set CMAKE_INSTALL_PREFIX, so ignore that part of my answer. Unfortunately, as far as I am aware it is not possible to split building with ExternalProject_Add into separate build and install steps, so your options essentially boil down to:

1) Give yourself write permissions for ${OUTPUT_PATH} and run the build. You should then probably remove write access for ${OUTPUT_PATH} again once you are done.

2) Run the entire build as root.

Since you should be doing as little as possible as root, I would strongly suggest option 1.
