Hi,

As noted in another thread (http://forum.abinit.org/viewtopic.php?f=17&t=1609), there is a build bug in all recent versions of Abinit. The m4 macro AX_PROG_MKDIR_P from util_fixes in both the fallbacks subtree and the tests subtree incorrectly tries to assign MKDIR_P a prefix of "fallbacks_srcdir", which isn't set anywhere. This is still a problem in 6.12.3.

The incorrect assignment leads to build failures if fallbacks are required and a fail during installation of the tests.

The quick workaround for users is simply to change fallbacks_srcdir to srcdir in every instance in the configure files in each subdirectory (it appears to be a relic variable).

The proper fix for developers is to update the AX_PROG_MKDIR_P macro. Just changing fallbacks_srcdir to srcdir might work here but I don't know if this breaks something on autoreconf (or whatever process is used by the abinit devs to generate the configure.ac files and so on).

Is there a higher purpose to the existence of the fallbacks_srcdir variable?

Thanks for reporting this problem. I'll fix it ASAP.

Hi Yann,

You'll need to apply that patch against tests/config/m4/util-fixes.m4 as well. It has the same problem.

You're just plain right. Same in doc/ as well.

Ah it's in ./tests as well.
