This package is nearly unmaintained upstream. Use the zpaq package if you want to compress with it, otherwise use some modern, maintained stream compressor.

I get a different error:

Same here, and if I change that line to libzpaq::compress(&in, &out, "3");

it builds, but segfaults.

Same with adding -fpermissive to the CXXFLAGS.
