_compress2 referenced in function "...
This is a function in zlib, a compression library. We only call it if we could
find zlib during the run of cmake, and have the following code at the top of
the file:
#ifdef DEAL_II_WITH_ZLIB
# include <zlib.h>
#endif
The fact that this code compiled to begin with means that the header file
zlib.h exists on your system. It's not clear to me, however, why it doesn't link.
When you compile the tutorial program, can you do
make VERBOSE=1
to get the complete command line for the linker? Or get this information in
some other way when linking the tutorial? I'm asking because there should be
an indication that it actually links with the zlib and I'd like to understand
how exactly it does that and what may go wrong in the process.
Best
