Can’t trigger breakpoints on macosx maverick

[Tristan Rybak]

Hello,
Just purchased the ultimate edition. I am really impressed how it flawlessly integrates with visual studio :).
I am trying to compile a c++ hello world project on mac mini with maverick 10.9.2.
I updated to the latest xcode, installed command line tools (by trying to execute gcc from the terminal).
the latest tools use lldb instead of gdb so I had to compile and install gdb 7.7 from sources using this link:
http://panks.me/blog/2013/11/install-gdb-on-os-x-mavericks-from-source/
I am able to compile the hello world project using remote llvm and I am able to run it from
visual studio remotely on macosx. I had to check “run debugger as root with sudo” to make it work,
The only problem is breakpoints set in visual studio don’t work, program just executes to the end. (I tried using gdb from the terminal on mac and the breakpoints work there).
When app starts I get this warning:
&”warning: GDB: Failed to set controlling terminal: Operation not permittedn”
then the output from the app
Hello, World!
and it quits (I tried to press F11 or set breakpoint manually).

The log from gdb sesson below.
Please help.

Hi,

This looks very strange. Could you please start GDB manually and run the following commands:

b main
run

Will the breakpoint be hit? If yes, please run GDB in MI mode (gdb –interpreter mi ) and run the following commands:

-break-insert main
-exec-run

Will this break in main()? In either case please provide us with the relevant GDB logs so that we could diagnose the problem further.

BTW, are you building a 32-bit version of the app or a 64-bit version? You may need to specify ‘-arch xxx’ in GDB command-line arguments to select the bitness manually.

Hi,
Just tried again and breakpoints in VS started to work… I have no idea why. Maybe macmini reboot helped.
I did the tests you requested, so posting them here in case breakpoints stop working :).
Thanks for the great tool!

Tristan
