I am trying to install GDB to work with LiteIDE, on Mavericks.
After some research, I found out that GDB does not come with Xcode anymore, and that you have to install it yourself. Short of actually installing GDB from source, and self code signing (id rather not do this), I would like to use MacPorts to get this done.
I did port install gdb, which ran and succeeded as far as I know. After the install, I closed terminal and then typed gdb and I get -bash: gdb: command not found
Does anyone have a solution for this, using MacPorts???
You should use the command "ggdb" to start the MacPorts' build of gdb.
I don't know why they have renamed it, probably a transient bug/change that will be fixed somehow, I suspect they wanted to avoid a collision with the alias "gdb" launching LLDB.
Edit: Reworded the answer to avoid ambiguities as reported by #trojanfoe
I finally figured it out, with some help from #xryl669. His tip that you have to use the command "ggdb" in order to access this port from macports, is correct. Also, however, I missed a command that displayed after the port installed:
You will need to make sure
/System/Library/LaunchDaemons/com.apple.taskgated.plist has the '-p' option,
e.g.
<key>ProgramArguments</key>
<array>
<string>/usr/libexec/taskgated</string>
<string>-sp</string>
</array>
To do this, type
sudo nano /System/Library/LaunchDaemons/com.apple.taskgated.plist
And then add the "p" after -s. I don't really know what this does, but after this "ggdb" command started working for me
Edit: Adding the p is recommended but simply using "ggdb" should do the trick
I don't have Mavericks yet, but since Xcode 4.3, the command-line tools are optional: https://developer.apple.com/library/ios/documentation/DeveloperTools/Conceptual/WhatsNewXcode/Articles/xcode_4_3.html
"The command-line tools are not bundled with Xcode 4.3 by default. Instead, they can be installed optionally using the Components tab of the Downloads preferences panel.".
I have Xcode 5.0.1 on OSX 10.8.5 and gdb is definitely there after doing the optional command-line tools install:
$ which -a gdb
/usr/bin/gdb
$ gdb --version

I spent some time and figured it out with help of great documentation.
1. Install ggdb using MacPorts: sudo port install gdb, the file will be /opt/local/bin/ggdb.
2. Follow tutorial https://www.ics.uci.edu/~pattis/common/handouts/macmingweclipse/allexperimental/mac-gdb-install.html and it works.
I spent number of days and many various tutorials, this one actually works !
Good luck.

I'm trying to install a cross-compiled gdb on an Apple M1 MacBook. I downloaded gdb 11.1 and did:
/tmp/src/gdb-11.1/configure --enable-targets=all
make
sudo make install
The commands seemed to have completed without error. All the relevant files seems to be installed when I check /usr/local/include, /usr/local/lib, etc., but the actual binary for gdb is nowhere to be found.
Ideas?
GDB is not supported on MacOS/m1 (aarch64).
You can track (authoritative) updates on the GDB discussion lists. The link below is latest status (July 2022). Currently there are no contributors working on it, only option appears to be LLDB (which should be able to handle "-O0" code).
https://inbox.sourceware.org/gdb/3185c3b8-8a91-4beb-a5d5-9db6afb93713#Spark/
I searched online about how to install gdb on macOS Sierra 10.12.2 but failed on the methods I could find. Then I figure out the following way which is easy and works fine on my machine. hope it may help you too:)
download the most recent GDB from https://www.sourceware.org/gdb/download/
expand the gdb-7.12.1.tar.xz file: tar xopf gdb-7.12.1.tar.xz
cd gdb-7.12.1 in terminal to open the gdb folder
then follow the instructions in the README file in the gdb folder, or simply follow the following steps:
./configure, wait for the terminal
make and wait again (which can take some time)
sudo make install
Now gdb is installed at /usr/local/bin/
Note that you might want to try/use LLDB (lldb) instead. This is now the default (don't know about 10.12, but on 10.13 it is installed, when you install the Xcode utilities). It even comes with a nice curses GUI, but otherwise a shell very similar to GDB.
You can also use homebrew to get gdb in mac os:
install-gdb-macos-sierra
Surprised no one mentioned:
brew install gdb
How to install brew?
I installed GDB 7.8.1 and GCC 4.9 through Homebrew.
When I open a core file generated by a GCC-compiled (gcc-4.9 -g xxx.c -o xxx) program, it reports:
→ gdb ./list_test /cores/core.1176

"/cores/core.1176": no core file handler recognizes format
I googled and found someone suggested to use LLDB instead of GDB.
Is is possible to use GDB to debug the core file? And is it because GDB does not support the binary format on Yosemite?
Based on the long GDB developers' discussion thread on this issue, it seems Apple did not merge their changes back to the official GNU mainline, and instead chose to publish the modified source code on their own site. As a result, the Homebrew GDB install (which uses the stock GDB sources) can't load OS X core files.
At this point, I see three choices:
Give in and learn LLDB. There's a GDB to LLDB cheat sheet to help.
Install Apple's custom GDB from MacPorts. I've long forsaken MacPorts, so I can't test it, but if you have MacPorts installed, try the following:
$ sudo port install gdb-apple
$ codesign -s <your_GDB_cert_id> /opt/local/bin/gdb-apple
$ /opt/local/bin/gdb-apple ./list_test /cores/core.1176
Translate MacPorts' GDB patches and build spec into a Homebrew formula. It's theoretically possible, but I don't have the time to do it myself.
Personally, I've opted to just learn LLDB. Apple has moved permanently to LLVM, so it's probably just a matter of time before the old patched GDB stops working with the latest-and-greatest Xcode tools.
I am a new Mac user and wonder how to install the latest version of GDB (> 7.1). I prefer to use Homebrew, but I could not find GDB listed.
brew install gdb
Error: No available formula for gdb
What is the best way to do it?
When installed Xcode, it may have installed an older version. Currently,
$ which gdb
/usr/bin/gdb
$ gdb --version
GNU gdb 6.3.50-20050815 (Apple version gdb-1705) (Fri Jul 1 10:50:06 UTC 2011)

But I need version > 7.1
System version,
Model Name: MacBook Air
System Version: Mac OS X 10.7.1 (11B2118)
Homebrew does not provide gcc and the associated development tool formulas over concerns that custom/non-system compilers could break builds. Two possibilities for easiness:
Use http://www.macports.org/
Look here https://github.com/mxcl/homebrew/wiki/Custom-GCC-and-cross-compilers
This is probably the command for you:
brew install https://raw.github.com/Homebrew/homebrew-dupes/master/gdb.rb
Some new users may find themselves in the same situation given the Mac OS X v10.9 (Mavericks) upgrade.
Solution
Install the development tools and Xcode
Then install Homebrew
Then do:
brew install homebrew/dupes/gdb
You will notice that some applications will not allow you to use the newly added GDB.
This is because it is not signed by Apple any more.
To side step this issue: Follow this; thanks to #andre
I've had some people hit me up on IRC for more detailed instructions for this. I made a post on my site. You can find it here.
This does not directly answer the given question, but if you're like me, what you really want is a simple way to run (something very much like) gdb.
Apple now uses Clang as its compiler, and it turns out that the clang debugger, lldb, is installed along with the other command-line tools. It appears that lldb is designed with a user interface that mimics gdb very closely.
So, the answer to your question may in fact be:
just use lldb!
I have a MacBook Pro that I'm trying to do some development on.
I have a program I want to build, and when I went to use make to build it, I got a "command not found" error. I did some googling and Stack Overflow searches and it doesn't look like this is a common problem. Why don't I have make installed and how do I get it?
I'm extra confused, because I know I used it relatively recently (in the past month or so) when I was on this laptop.
For those of you who get to this page using Xcode 4.3 and Lion, the command line tools are no longer bundled by default, and there is no /Developer anymore. To install them, open Xcode, go to Preferences -> Downloads -> Components -> Command Line Tools. This should install make, gcc etc.
Have you installed the Apple developer tools?
What happens if you type gcc -v ?
It look as if you do not have downloaded the development stuff. You can get it for free (after registration) from http://developer.apple.com/
There is now another way to install the gcc toolchain on OS X through the osx-gcc-installer this includes:
GCC
LLVM
Clang
Developer CLI Tools (purge, make, etc)
DevSDK (headers, etc)
The download is 282MB vs 3GB for Xcode.
You will have to install the "Developer Tools" that are provided as optional packages in OS X installation disks.
For Xcode 4.1 you can simply add /Developer/usr/bin to the PATH environment variable. This is easily done:
$ export PATH=$PATH:/Developer/usr/bin
Also be certain to update your ~/.bashrc (or ~/.profile or ~/.bash_login) file.
In addition, if you have migrated your user files and applications from one mac to another, you need to install Apple Developer Tools all over again. The migration assistant does not account for the developer tools installation.
If you've installed Xcode 4.3 and its Command Line Tools, just open Terminal and type the following: On Xcode 4.3, type the following in Terminal:
export PATH=$PATH:/Applications/Xcode.app/Contents/Developer/usr/bin
#Daniel's suggestion worked perfectly for me. To install make, open Xcode, go to Preferences -> Downloads -> Components -> Command Line Tools.You can then test with gcc -v
I agree with the other two answers: install the Apple Developer Tools.
But it is also worth noting that OS X ships with ant and rake.
I believe you can also get just the Xcode command-line tools which is about 170 MB.. It's described in the 'brew' setup guide: https://github.com/mxcl/homebrew/wiki/installation and can be found here: https://developer.apple.com/downloads/index.action#
Edit: this was already mentioned above by #josh
I found the Developer Tools not as readily available as others. In El Capitan, in terminal I just used gcc -v, it then said gcc wasn't available and asked if I wanted to install the command line Apple Developer Tools. No downloading of Xcode required. Terminal session below:
Pauls-MBP:~ paulhillman$ gcc -v
xcode-select: note: no developer tools were found at '/Applications/Xcode.app', requesting install. Choose an option in the dialog to download the command line developer tools.
Pauls-MBP:~ paulhillman$ gcc -v
