--- Comment #7 from Peter VARGA <developm...@faf-ltd.com> --- This is the original version: #include <algorithm> #include <atomic> #include <chrono> #include <cmath> #include <condition_variable> #include <cstdlib> #include <forward_list> #include <fstream> #include <functional> #include <iostream> #include <map> #include <mutex> #include <regex> #include <set> #include <string> #include <thread> #include <vector> #include <execinfo.h> #include <gnu/libc-version.h> #include <libgen.h> #include <locale.h> #include <signal.h> #include <stdarg.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <sys/poll.h> #include <sys/resource.h> #include <sys/socket.h> #include <sys/stat.h> #include <sys/syscall.h> #include <sys/sysinfo.h> #include <unistd.h> #include <mysql/my_global.h> #include <mysql/mysql.h> Before I found now finally a solution I had to sort out the order - it was not really that trivial and very annoying. This is now how it works and - as it should be - the order of the include files in the project does NOT matter anymore. BUT, it is very important that /usr/include is last in the list, otherwise it won't compile: -nostdinc -I /FaF/curl/include -I /usr/include/mysql -I /FaF/lib64/gcc/x86_64-suse-linux/7.3.0/include-fixed -I /FaF/include/c++/7.3 -I /FaF/include/c++/7.3/x86_64-suse-linux/ -I /FaF/lib64/gcc/x86_64-suse-linux/7.3.0/include -I /FaF/glibc/include/ -I /usr/include
