compilation issues in Ubuntu 24

[cbz20]

Running make causes errors in Ubuntu 24.04.2 LTS. The compiler, clang, appears to have troubles finding all of the relevant files. The problem seems to be worse if g++ is used instead of clang.

Temporary Fix

Replace
%.o : CPPFLAGS = -std=c++17 -O3 -fPIE -Wall $(LIBS) -MD -DNDEBUG -DVERSION=\"$(GIT_VERSION)\"
in the makefile by
%.o : CPPFLAGS = -std=c++17 -include stdint.h -O3 -fPIE -Wall $(LIBS) -MD -DNDEBUG -DVERSION=\"$(GIT_VERSION)\"
