The issue was the same as you pointed out: that is, the version of the
compiler. It worked for me
only with gcc-6. Trying with gcc-7 the build process ends upwith the
mentioned non declared functions.
No idea about a possible solution so far.About the missing symbols you
say you're getting,
they might be related with the use of-jN together with higher versions
of gcc. It happened to me building
bulmages a few years ago,an accounting program, when we were migrating
it from Qt4 to Qt5: using -j1 it worked.
All the same, i tried with gcc-7, and the strtol function (declared in
<stdlib.h> without any precompiler directive)
was not recognized.

Cheers,

Aitor.
