I need to use gdb.
ps-MacBook-Air:AcoustoExport pi$ gdb
-bash: gdb: command not found
ps-MacBook-Air:AcoustoExport pi$ sudo find / -iname "*gdb*"
Password:
/usr/local/share/gdb
/usr/local/Cellar/isl/0.12.1/share/gdb
:
and:
ps-MacBook-Air:AcoustoExport pi$ ls -la /usr/local/share/gdb
lrwxr-xr-x 1 pi admin 30 14 Jan 22:01 gdb -> ../Cellar/isl/0.12.1/share/gdb
Not quite sure what to make this, clearly it is something installed by homebrew. I don't know why it's there, I don't know whether I could use it instead. It isn't in the search path.
So I figure I need Xcode commandline tools.
Xcode is not currently available from the Software Update server
^ my current problem exactly. Comment on that question says "you can get this error if you have them already"
But how do I check whether I have them already?
This question is related to
xcode
command-line
installation
If for some reason xcode is not installed under
/usr/bin/xcodebuild
execute the following command
which xcodebuild
and if it is installed, you'll be prompted with it's location.
Thanks to the folks on Freenode's #macdev, here is some information:
In the old days before Xcode was on the app-store, it included commandline tools.
Now you get it from the store, and with this new mechanism it can't install extra things outside of the Xcode.app, so you have to manually do it yourself, by:
xcode-select --install
On Xcode 4.x you can check to see if they are installed from within the Xcode UI:
On Xcode 5.x it is now here:
My problem of finding gcc/gdb is that they have been superseded by clang/lldb: GDB missing in OS X v10.9 (Mavericks)
Also note that Xcode contains compiler and debugger, so one of the things installing commandline tools will do is symlink or modify $PATH. It also downloads certain things like git.
I was able to find my version of Xcode on maxOS Sierra using this command:
pkgutil --pkg-info=com.apple.pkg.CLTools_Executables | grep version
as per this answer.
if you want to know the install version of Xcode as well as Swift language current version:
Use below simple command by using Terminal:
1. To get install Xcode Version
xcodebuild -version
2. To get install Swift language Version
swift --version
For macOS catalina try this : open Xcode. if not existing. download from App store (about 11GB) then open Xcode>open developer tool>more developer tool and used my apple id to download a compatible command line tool. Then, after downloading, I opened Xcode>Preferences>Locations>Command Line Tool and selected the newly downloaded command line tool from downloads.
First of all, be sure that you have downloaded it or not. Open up your terminal application, and enter $ gcc
if you have not installed it you will get an alert. You can verify that you have installed it by
$ xcode-select -p
/Library/Developer/CommandLineTools
And to be sure then enter $ gcc --version
