error compiling with gcc 4.8.5

[aspitaleri]

Hi there,
ViennaRNA 2.5 compiling was dying here:

../dlib-19.22/dlib/all/libRNA_concentrations_la-source.lo
with no error at all.
Update to gcc version > 7 everything went smoothly.

My configure is
./configure --prefix=/SOFTW/ViennaRNA-2.5 --with-kinwalker --with-cluster --with-python3 --without-cla-pdf --without-cla

[B199944-2021]

In my case, some error message would pop out. The dlib 19.22 has dropped support for GCC 4.85, which was the default compiler for centos 7 and some other Linux systems. I think they'd better update this issue on the install page next time.

That is unfortunate! We added dlib to our source tree for version 2.5.0 to efficiently compute concentration dependencies upon multi-strand interactions. Apparently, dlib requires a more recent compiler that actually implements the C++17 standard, which is only available since GCC 5.
I'll see whether I can put a more prominent note in the build requirements section.
