How to debug binaries with cdtdebug.sh from command line? [message #1754588]

I try to debug a program not built with eclipse (but with some custom build system) using the standalone cdtdebug.sh script:
cdtdebug.sh -e /path/to/my_program some args

But when the GUI has started up, I cannot start debugging immediately:

Launching 'New_configuration' has encountered a problem. Program file does not exist

When I click on the /path/to/my_program in the Executable tab (the executable is automatically entered there), I get an error:

An internal error occurred during: "Reading Debug Symbol Information: boost".

Only after I enter the path to the executable manually in the Debug configuration, I can start debugging, which makes me wonder: shouldn't the -e switch provide that?

So my question is: is there an easy way I can start debugging just using some command from the command line?

The reason I want this is I have several different executables and would like to avoid having to enter their paths manually each time, or select some configuration, but rather jump-start to debugging each using my custom debugging launcher.
N.B.: It was possible to do this with the intel debugger idb (which was based on the eclipse framework) but they deprecated that, so I'm trying to switch to eclipse debugging.

It looks like there might be a bug in CDT's Dwarf parsing. Can you try with another executable with debug info, like a simple hello world? Also, is this using the new Dwarf 5 by any chance? I'm asking in case because the spec just came out Wink

I am getting the same DWARF parsing error, just when I click on some executable in the "Executables" view. Here's the full trace:

Oddly, this problem happens only with the "debug" version of my binary, not the release one (but debug info is included in both).

My binary is a mix of C and asm code, with the C code apparently writing DWARF 2 and the asm writing DWARF 3. The crash seems probably related to the asm code since changing the debug format to stabs for the asm avoids the crash.

The program I'm trying to debug is a mix of C/Fortran and it's a large executable. A simple hello-world-like fortran program can be debugged, however.
