Hi,
I tried to reproduce this with gcc 7.0.1, but still no luck. It doesn't
matter whether I compile PoDoFo as a static library (the default) or as
a shared library, neither whether I use Boost or Lua or some other
optional dependencies on or off (my podofo_config.h currently shows
that I have all the development libraries installed and available).
I use the attached code, which is the same as yours, it only avoids a
memory leak and unused variable, thus neither gcc nor valgrind claim
any issue. The file contain my steps (note the missing `make install`,
the code is run out of the build tree) at the top of it.
Maybe I do something wrong?
Bye,
zyx
