I tried to compile in centos7 with gcc4.8 installed. But failed to build, got the error:

running: "cc" "-O0" "-ffunction-sections" "-fdata-sections" "-fPIC" "-gdwarf-4" "-fno-omit-frame-pointer" "-m64" "-I" "c_src/mimalloc/include" "-I" "c_src/mimalloc/src" "-Wall" "-Wextra" "-ftls-model=initial-exec" "-DMI_DEBUG=0" "-o" "/root/ql/kubectl-watch/target/debug/build/libmimalloc-sys-83bf035ad26abe40/out/c_src/mimalloc/src/static.o" "-c" "c_src/mimalloc/src/static.c"

  exit status: 1

  --- stderr

And I found glibc version must be greater than 4.9.

This file is missing. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58016
It was fixed only in gcc 4.9, as its release notes says (http://gcc.gnu.org/gcc-4.9/changes.html)
