Mark, It is quite evident that the conditional compilation is missing. However, for full verification of the bug I do require the info on OS, its version, and versions of cmake, make and C / C++ compiler. Thanks in advance.

Indeed, it is the error in missing a conditional compilation. Fully verified.

Noted in 5.7.6 changelog. The -DENABLED_PROFILING=0 CMake option resulted in compilation errors.
Description: I get this error from sql/mysqld.cc /s/bld/orig575/sql/mysqld.cc: In function ‘void my_init_signals()’: /s/bld/orig575/sql/mysqld.cc:2044:21: error: aggregate ‘my_init_signals()::rlimit rl’ has incomplete type and cannot be defined /s/bld/orig575/sql/mysqld.cc:2045:33: error: ‘RLIM_INFINITY’ was not declared in this scope /s/bld/orig575/sql/mysqld.cc:2046:21: error: ‘RLIMIT_CORE’ was not declared in this scope /s/bld/orig575/sql/mysqld.cc:2046:37: error: ‘setrlimit’ was not declared in this scope The 5.7.5 code is not protected by ifdefs: if (test_flags & TEST_CORE_ON_SIGNAL) { // Change limits so that we will get a core file. struct rlimit rl; rl.rlim_cur= rl.rlim_max= RLIM_INFINITY; if (setrlimit(RLIMIT_CORE, &rl)) sql_print_warning("setrlimit could not change the size of core files to" " 'infinity'; We may not be able to generate a" " core file on signals"); } The similar 5.6 code was protected and the file included <sys/resource.h> #ifdef HAVE_GETRLIMIT if (test_flags & TEST_CORE_ON_SIGNAL) { /* Change limits so that we will get a core file */ STRUCT_RLIMIT rl; rl.rlim_cur = rl.rlim_max = RLIM_INFINITY; if (setrlimit(RLIMIT_CORE, &rl) && log_warnings) sql_print_warning("setrlimit could not change the size of core files to 'infinity'; We may not be able to generate a core file on signals"); } #endif How to repeat: run cmake, make Suggested fix: include <sys/resource.h>
