I stumble on the following error message after the shown command.
Is there any more fine-tuning needed to support the configuration variant that generated files will be stored in directories which are separate from the corresponding source directory hierarchy?
What distro are you using?
I am trying to build this configuration variant on my openSUSE 13.1/Tumbleweed system.
(Building the software works as epxected if only the source directories will be referenced by "an ordinary configuration".)
Looking at the errors above - this is easily fixed by adding the location of libfix8.so to your LD_LIBRARY_PATH and by adding additional -L specifications.
If you think this can be improved perhaps you could provide an updated configure.ac
Will revisit if more information is provided by reporter.
