After installing all dependencies, the very next step is to install IMAS itself. During this installation the cpp interface component is complaining about blitz not being compiled in thread-safe
manner and suggests that maybe the -pthread
flag was missing during Blitz compilation/installation. The bad news is that the whole eco-system was compiled using at least those two flags: '-fPIC -pthread'
, therefore the error is confusing. Below you can find an error message from reproduction attempt:

As you can see for some reason IMAS is complaining on Blitz being compiled with --enable-threadsafe
flag but at the same time no thread support for compiler is found:

How to reproduce issue
Solution
After a long search a solution has been found, however it is not very elegant. Requires editing pkg-config for Blitz, which by default is prepared by SPACK.
The change is subtle and affects only CFLAGS
which should look like this:

Cflags: -I${includedir} -pthread |
