Lapack: Bad LAPACK_DIR in lapacke-config.cmake

Created on 11 May 2021 · 3Comments · Source: Reference-LAPACK/lapack

Description

I've installed lapack v3.9.1 through homebrew w/ brew install lapack, and I'm trying to use it in a CMake project, but I have manually modify lapacke-config.cmake because the LAPACK_DIR appears to be malformed.

On fresh install with version 3.9.1, the line is:

set(LAPACK_DIR "${_LAPACKE_PREFIX}/lib/cmake/-3.9.1")

And it should be:

set(LAPACK_DIR "${_LAPACKE_PREFIX}/lib/cmake/lapack-3.9.1")

I've done a bit of digging and I believe the issue was introduced here: https://github.com/Reference-LAPACK/lapack/blob/2dafa3d2756a7825c23a8c8456781561e36668ae/LAPACKE/cmake/lapacke-config-install.cmake.in#L8 in the most recent commit.

Where perhaps @LAPACK@ is undefined (sorry I'm at the edge of my CMake knowledge)... should it be @LAPACKLIB@ instead?

@weslleyspereira Oops, sorry about this. Yes, this is a typo, it should've been @LAPACKLIB@.

As @5tefan has keenly spotted it, I'll let them make the PR :wink: .

Hi @5tefan. This is indeed a problem, and I think you got the answer.

The same problem occurs in my Linux machine.
The tag @LAPACK@ was introduced in 5dd47be6720f97182a240efb8363ed58518ed12f. Based on the changes there, I think this is a typo. Could you please review this, @epsilon-0 ? Thanks in advance.
