Hi I am new to MAC Lazarus but have used Delphi in past.
Running Lazarus 1.4.0
FPC 2.6.4 and FPCSRC 2.6.4.
having found debugger was missing downloaded via home-brew and set
certificate as required.
Simple project with button compiled ok but then failed on run with
different errors on each run

The GDB command:
"-exec-run"
returned the error:
",msg="Unable to find Mach task port for process-id 3146: (os/kern)
failure (0x5).\n


The GDB command:
"-exec-run"
returned the error:
",msg="Unable to find Mach task port for process-id 3157: (os/kern)
failure (0x5).\n


The GDB command:
"-exec-run"
returned the error:
",msg="Unable to find Mach task port for process-id 3169: (os/kern)
failure (0x5).\n

Can anyone suggest anything to try please?

It appears you've missed the GDB signing step. It's not just setting
up a certificate, it's also "codesign" gdb.

Hi Thanks, I have checked that I have set up the certificate and set
trust to
Code signing always allow.When I try to codesigb I got the error

Johns-iMac:~ johnpayton$ codesign -s gdb-cert /usr/local/bin/gdb
gdb-cert: this identity cannot be used for signing code
Johns-iMac:~ johnpayton$

What have i done wrong?

I have rerun setting the certificate and signed it.
Terminal says gdb-cert is already signed but Lazarus says it isn't?
Where do I go from here?

Johns-iMac:~ johnpayton$ codesign -s gdb-cert /usr/local/bin/gdb
/usr/local/bin/gdb: is already signed
Johns-iMac:~ johnpayton$


"-exec-run"
returned the error:
",msg="Unable to find Mach task port for process-id 482: (os/kern)
failure (0x5).\n (please check gdb is codesigned - see taskgated()""
