Solve the problem of compiling and installing gdb-10.1 unistd.h:663:3: error: #error “Please include config.h first.”

​   Recently installed the C++ compilation environment in Arch, I thought it would be solved directly by pacman -S cmake gdb, but when I configured the environment in clionIt was prompted that the versions of cmake and gdb are too high, so I had to download them from the official websites of cmake and gdb. The official website of cmake provides binary files, and you can directly call them by decompressing them in a directory.And gdb needs to be compiled by itself, here is gdb-10.1.

​   As usual, pass ./configure, make, make install, compile error...

 CXX nat/amd64-linux-siginfo.oIn file included from /usr/include/bits/sigstksz.h:24,from /usr/include/signal.h:315,from ../gnulib/import/signal.h:52,from /ironwood1/sourceware-git/rawhide-gnulib/bld/../../worktree-gnulib/gdbserver/../gdb/nat/amd64-linux-siginfo.c:20:../gnulib/import/unistd.h:663:3: error: #error "Please include config.h first."663 | #error "Please include config.h first."^~~~~

​ The reason is because the header file introduced by glic-2.33 has changed. To solve this problem, you only need to open ./gdb-10.1/gdb/nat/amd64-linux-siginfo.c , put

#include #include "gdbsupport/common-defs.h"

​   Modified to

#include "gdbsupport/common-defs.h"#include 

Recompile and install, the problem is solved.
