gbd on Mavericks.... so close....

[JimKueneman]

I followed the direction here:

http://wiki.freepascal.org/GDB_on_OS_X_Mavericks_and_Xcode_5

All went as planned.... except

The GDB command:
"-exec-run"
returned the error:
",msg="Unable to find Mach task port for process-id 451: (os/kern) failure (0x5).\n (please check gdb is codesigned - see taskgated()""

It seems like it is signed so what could be wrong?

Jim-iMac:python jimkueneman$ codesign -vvv /usr/local/bin/gdb
/usr/local/bin/gdb: valid on disk
/usr/local/bin/gdb: satisfies its Designated Requirement

Tools->Options>Debugger->Debugger Path = /usr/local/bin/gdb

I do notice that this gdb file is a hardlink to the actual executable that homebrew compiled.

could you please try to "sudo" lazarus?

[JimKueneman]

Hi,

   No go.  I ran

sudo open lazarus.app

same error:

The GDB command:
"-exec-run"
returned the error:
",msg="Unable to find Mach task port for process-id 1121: (os/kern) failure (0x5).\n (please check gdb is codesigned - see taskgated()""

Any other thought what I can do?  If anyone is willing I am willing to run remote access of my iMac to try to figure this out. I am not well versed in OSX's internals so I am helpless. This will be a real roadblock for Lazarus on a Mac if this is an issue.

Thanks,
Jim

Try to run GDB directly, then use the new gatekeeper exceptions dialog described Here to forcedly allow the last run blocked application.

[sysrpl]

I have Mavericks installed and was able to setup debugging using macports:

curl https://distfiles.macports.org/MacPorts/MacPorts-2.2.1-10.9-Mavericks.pkg -o macports.pkg
sudo installer -pkg macports.pkg -target /
sudo port install gdb

The debugger will then be located at:

/opt/local/bin/ggdb

You will need to sign ggdb using the steps provided here:

http://www.opensource.apple.com/source/lldb/lldb-69/docs/code-signing.txt

Substitute ggdb for lldb and it should work.

Ok I ran:

open /usr/local/bin/gdb

and gdb opened right up:

I run Lazarus and hit the Run button and I get this:

The GDB command:
"-exec-run"
returned the error:
",msg="Unable to find Mach task port for process-id 2406: (os/kern) failure (0x5).\n (please check gdb is codesigned - see taskgated()""

I am lost...

sysrpl :
  I think the home-brew compile and signing did everything that macports would do.  gdb is compiled and will run off the command line but not through Lazarus.

BTW I am running the release candidate for 1.2.

Not sure if this is of any help but here is the console logging if I try to compile and run the debugger:

Then the Debugger Error dialog pops up.

Arrrggggg....  I missed this:

open the “Trust” item, and set “Code Signing” to “Always Trust”.

For others this took me a while to find...

[skalogryz]

good to know.

So even though gdb was signed, the certificate was not trusted enough.

[JimKueneman]

Correct, "Use System Defaults" was not trusted enough.  I also removed home-brew and used MacPorts but I am sure what fixed it was this as the MacPorts build of ggdb had the same problem until I changed it to Always Trust.

[danysz]

For me is still not working and the certificate is signed "always trust"
I just have gdb 7.7
