Conflict between the pure function stdlib_iparam2stage and openmp #825
Description
Description
Environment
gfortran 13.2.0 (Built by MSYS2 project)
fpm 0.10.1, alpha
Detail
When OpenMP is enabled, an error will occur when calling functions in stdlib_linalg module.
If we create a new project via fpm and then add the following code in fpm.toml to enable OpenMP and stdlib
[dependencies]
openmp = "*"
stdlib = "*"
And then call the eye function in main program
program main
use stdlib_linalg, only: eye
real :: A(3,3)
A = eye(3)
end program main
Then building with fpm will result in the following error :
build\dependencies\stdlib\src\stdlib_linalg_lapack_aux.F90:1436:25:
1436 | !$ nthreads = omp_get_num_threads()
| 1
Error: Reference to impure function 'omp_get_num_threads' at (1) within a PURE procedure
Expected Behaviour
No errors when building.
Version of stdlib
Platform and Architecture
Windows, MSYS
