Disable libctf?

Disable libctf?

[Sebastian Huber]

Hello,

a recent change broke the GDB build on my FreeBSD test machine:

gmake[2]: Leaving directory 
'/usr/home/user/rtems-source-builder/rtems/build/aarch64-rtems6-gdb-119e99b-x86_64-freebsd12.1-1/build/libctf'
configure: WARNING: libdebuginfod is missing or unusable; some features 
may be unavailable.

[...]

checking for libgmp... no
configure: error: GMP is missing or unusable

I guess I don't need libctf to debug non-Linux embedded systems? I tried 
to use --disable-libctf, but this didn't work.

Isn't the problem that GMP is missing? Or the pasted log may be misleading.

Sorry, the problem had nothing to do with libctf. It seems GMP is now 
required to build GDB:

commit 1b4ac058f7daeb9bac9ab0e63a7e73535208dfef
Author: Joel Brobecker <brobecker@adacore.com>
Date:   Sun Nov 15 03:08:40 2020 -0500

     gdb: Make GMP a required dependency for building GDB

     This commit modifies gdb's configure script to trigger an error
     if we cannot find a usable libgmp.

     For the record, making this a requirement was discussed in March 2018:
https://sourceware.org/pipermail/gdb-patches/2018-March/147373.html

     gdb/ChangeLog:

             * configure.ac: Generate an error if a usable GMP library
             could not be found.
             * configure: Regenerate.
