Re: [photran] Problems trying to debug in Mac OSX
Hi,

a colleague of mine had the exact same problem that Peter described (he also uses Snow Leopard 10.6.7):
programs compile and run (both with and without debug information), but don't stop at breakpoint.

Solution: Install latest GCC / gfortran from macports (I am not a mac guy myself). In particular, it didnt work with GCC 4.2.3 but it did with 4.5!

Hope that helps.

Ferran,

Not much help here but;

I have been unable to debug with a hand-written makefile as well, with no optimisation and debug/symbols etc.
Program simply executes with no regard to breakpoints. Tried a lot of things with no success. Can not see anything
in the Photran make that should make a difference.

Same Photran base as yourself and Snow Leopard 10.6.7.

I leave all [default] error parsers checked .

If I let Photran handle the make all is well and debugging works.

Cheers

Hi folks,

let me start saying that this is my first post here
and that I'm absolutely new to eclipse itself so 
please excuse me if i start to ask stupid questions
that anybody knows hot to solve...

The fact is that I'm trying to use Photran on Eclipse
under Mac OSX. I'm running that under Snow Leopard
10.6.7 with gfortran. I jave had partial success in 
the sense that I can compile simple programs, but not
debug them in any sense. Compiling and running works
fine (apparently), but I can't make the debugger work.

I run into troubles when i try to follow the Photran 6.0
guide example. So i go to the guide:
download 
eclipse-SDK-3.6.2-macosx-cocoa-x86_64.tar.gz
which I can install with no apparent problems following 
the instructions given on the guide. I can then execute
eclipse from the terminal and it shows up nicely.
Then I go to section 'Starting a New Project'->
'Starting a Project with a Hand-Written Makefile'
and follow the steps listed there. A few details change,
for instance:

Step 7: when I go to 'Binary Parsers Tab' I check 
'Mach-O 64 Parser' and not 'Mach-O Parser (deprecated)' 
as mentioned in the guide. 

Step 8: In the 'Error parser' Tab many options appear actually
checked by default. I check also 'Photran error
parser for GNU fortran (gfortran)' and uncheck all
the others... is that right?

I actually follow the instructions and I can run my hello.f90
example code right. However when i try to debug it, I just go to 
Run -> Debug As -> Local Fortran Application 
and it tries yo compile, but then opens up an Error window
with the message:
'Failed to set program arguments, environment or working directory.
Unable to set working directory: "/Users/mazzanti/Documents/workspace/HelloFortran": No such file or directory.
Unable to set working directory: "/Users/mazzanti/Documents/workspace/HelloFortran": No such file or directory.
Unable to set working directory: "/Users/mazzanti/Documents/workspace/HelloFortran": No such file or directory.'
..while the folder does exist and have write permissions, etc.
Also the console spits
'"/Users/mazzanti/Documents/workspace/HelloFortran": No such file or directory.

warning: `/var/folders/NZ/NZ5z7FgcGviD8PoqN6bz4k+++TI/-Tmp-//ccNcHp7I.o': can't open to read symbols: No such file or directory.
.gdbinit: No such file or directory.
Reading symbols from /Users/mazzanti/Documents/workspace/HelloFortran/hello.exe...(no debugging symbols found)...done.'

...and that's the end of the story.

Can anybody please help me with this? HHow could I make it work?

Thanks in advance :)
