README for this repository

The change has already been commited to the GDB main branch: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=7ff917016a203cdff3074abfcf96c1553944af94

You can now build from the main working branch of GDB instead of building from this repo. I am archivin this repository.

The repository is the modification of the GNU GDB-11.2: Source code: https://ftp.gnu.org/gnu/gdb/gdb-11.2.tar.gz

The bug of GDB hang on Mac OS X has been reported a long time ago and it still persists in the latest GDB 11.2 release. There is a solution from domq for GDB 10.2: https://github.com/domq/homebrew-gdb/blob/master/Formula/gdb.rb

In this repository, I simply moved part of the change from the domq to GDB 11.2 and seems like the GDB 11.2 can work most of the time. I have tested it under OS X 12.2 Intel-based macbook pro. It is still possible that the gdb will hang waiting of the new forked process due to the

gdb/nat/fork-inferior.c: 488 target_wait()

How to build GDB from source

  • Go to the source directory and run
mkdir build
cd    build
../configure --prefix=/usr
make
  • GDB should now build in build/gdb, change directory to folder gdb and then codesign the gdb executable
cd gdb
codesign --entitlements ../../darwin_gdb_xml/gdb-entitlement.xml -fs gdb-cert ./gdb
  • You should now be able to run the build/gdb/gdb and debug your code.

Original README for GNU GDB

The following is the README from the original GNU GDB Repository

	   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.:

./configure 
make

To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install

(If the configure script can't determine your type of computer, give it the name as an argument, for instance ./configure sun4''. You can use the script config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.)

If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh):

CC=gcc ./configure
make

A similar example using csh:

setenv CC gcc
./configure
make

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
