Lack of installation / separate write directories

It looks like CBL is designed to be run in the same directory where it's compiled, and that read/write access is needed to the compile/run tree at runtime. Is this correct?

If so, this makes some ways of using CBL very difficult. In particular, I'm trying to use it inside a Docker container, with container managers on HPC systems and elsewhere that mount the Docker container's filesystem as read-only.

The first issue is the lack of installation options -- I have coped by just copying the whole compile tree into the container. It would be nice if there was a "make install" equivalent that allowed a runtime to be copied to something under (say) /usr/local.

The bigger problem is that CBL seems to need to read and write within its own tree, rather than having user files written to something (say) underneath a user's home directory. This means that it's not possible to have a "system" install of CBL, but that the only practical way to use it is for the user to compile it and run it in their own directory. And, this doesn't work if you build CBL in a container where the filesystem built into the container is not supposed to be writeable.

How hard would it be to separate this out? The first errors I hit were with a call to sed, and a quick grep suggests that there are a lot of these calls in the code.

Is it possible to find out which directories need to be written to? Then a hackaround might be possible where those directories are copied to a writeable volume inside the container.

EisensteinHu - with or without BAOs?

It is no clear to me whether the implemented EisensteinHu transfer function includes the BAO wiggles or not. From the reference in the class documentation, it seems that this is the no wiggle TF. It would be great if this could be clarified.

Compilation Error at read_pk2.f

Hi, I can't compile the code.
after verifying that all required dependencies (listed in documentation) were installed, I do a fresh checkout and make don't compile the code:

$ make
