Hi,
after trying to install the library, I encountered initially the following error:
... LELA-master/install-sh: ./html/* does not exist.
It seems that the doc/Makefile.am tries to locate the html folder instead of the reference. After renaming it to html and re-executed the./configure; make; make install;the installation process went on smoothly.
I also renamed the reference.doxy file to html.doxy ; not totally sure if needed.
Thank you!
