In Carbide 2.0.2, if I set active configuration to be "Phone Debug GCCE", build the project, go to Debug perspective, choose "Executables" tab, and select the executable file, Source File Name/Location window will list all the files I am able to use while debugging.
The problem is that the list does not contain all files from the project, even though their code is successfully linked and executed on a device. As a consequence of the issue, I am not able to set break points in these files.
What is the catch and how can I fix it?
Thank you.
This is a problem with the version of GCCE that is used by default with Symbian. It has a number of bugs with debug information, including sometimes missing line information for some files.
The alternatives are (a) the commercial RVCT compiler, or (b) follow the in-progress work to move to a newer GCCE compiler. A good start for that is here:

I have a question regarding the nunit3-console. When running tests through it I am observing a generation of log files like internal-trace and nunit-agent text files.
I was able to disable the generation of the internal-trace with the --trace=off option but for each run having the test .dll specified I am noticing a nunit-agentNumber.txt file generated.
My question is, is this a problem? More specifically for CI/CD and is there an option to disable this? Or clean it at least after each run.
Version 3.15 of the engine introduced a new internal feature, allowing code to change the level of debugging dynamically. (Not yet exposed to users, but intended to be eventually)
As a side effect, it looks as if empty log files are being created. For the moment, the only way to avoid this is to go back to the previous release.
A fix was created in the development code for version 4.0, but has not been ported back to the version 3 code. A bug report might help with that. :-)
An "Errors exist in the active configuration of project X. Proceed with launch?" dialog appears while debugging code in Eclipse. Hitting the "Proceed" button results in successful debugging. There are no apparent errors with the launch configuration. A similar Run Configuration does not generate the error.
This is caused by an invalid path somewhere in your Eclipse project settings. There are a couple common sources for this kind of error.
You're working on a shared (version controlled, copied, etc) project where someone has hardcoded a path that doesn't exist on your machine, or uses an environment variable that you've not set.
Sometimes, you can find the offending path by looking at the full list of Error messages. If not, look in your project file.
The Discovery Options in your project properties has 'Automate discovery of paths and symbols' enabled - but the process is generating an error.
If you're using a version of Eclipse that warns you this option is deprecated, uncheck the option to disable it and fix any includes in 'Preprocessor Include Paths' instead. If not. . .try it anyway.
Depending on your path changes, restart Eclipse and try again.
It starts the executable that was built last before you broke the build. That executable will be older then your source files. The reason you were able to debug is because your line numbers did not change for the code you've debugged - e.g. you may try break in main then introduce a compilation error and move main a couple lines below - the debug will highlight the wrong lines when it stops.
I'm trying to debug a program written using Go inside eclipse. I can set and hit breakpoints pretty consistently, but I cannot view the contents of my variables. When I start debugging the program, I always get the following error on my console.
warning: File "/usr/local/go/src/pkg/runtime/runtime-gdb.py" auto-loading has been declined by your `auto-load safe-path' set to "$debugdir:$datadir/auto-load".
To enable execution of this file add
add-auto-load-safe-path /usr/local/go/src/pkg/runtime/runtime-gdb.py
line to your configuration file "/home/johnlawrie/.gdbinit".
To completely disable this security protection add
set auto-load safe-path /
line to your configuration file "/home/johnlawrie/.gdbinit".
For more information about this security protection see the
"Auto-loading safe path" section in the GDB manual. E.g., run from the shell:
info "(gdb)Auto-loading safe path"
Thinking that the problem might be due to the error message, I put the entry into my .gdbinit file as instructed. However, I get the same message every time I run as if I did nothing at all. This is the contents of my /home/johnlawrie/.gdbinit file
add-auto-load-safe-path /usr/local/go/src/pkg/runtime/runtime-gdb.py
Any ideas what I need to do to make this change take effect? I have tried logged off and back in.
Thanks,
John Lawrie
It did learn what was happening. When gdb is started from Eclipse/CDT, it is started with option -nx, which means it doesn't load .gdbinit in the home directory.
I was able to get this to work by creating a .gdbinit file as a peer to the src, bin, and pkg directories in my workspace and adding the following line to it
set auto-load safe-path /usr/local/go/
It should be add-auto-load-safe-path /usr/local/go/src/pkg/, not the path to the script.
Also keep in mind that gdb doesn't really work with Go, specially v1.3.
From http://golang.org/doc/gdb:
GDB does not understand Go programs well. The stack management,
threading, and runtime contain aspects that differ enough from the
execution model GDB expects that they can confuse the debugger, even
when the program is compiled with gccgo. As a consequence, although
GDB can be useful in some situations, it is not a reliable debugger
for Go programs, particularly heavily concurrent ones. Moreover, it is
not a priority for the Go project to address these issues, which are
difficult. In short, the instructions below should be taken only as a
guide to how to use GDB when it works, not as a guarantee of success.
In Eclipse(version 3.6.2.M201102101200/Helios service release 2). I am getting a strange error when I run a large Java project called ACE toolkit. Below is a picture:
What are possible reasons it would do this?
can it be that Java runtime version is incompatible? The project was built for Java 1.5, but I have 1.6 running.
I appreciate any tips or advice.
There could be any number of reasons for eclipse crashing, from insufficient memory to a misbehaving plugin. The first place to start troubleshooting would be the C:\path\to\your\workspace\.metadata\.log file. You might find something helpful if you examine the end of this file soon after eclipse crashes.
From the documentation:
Eclipse has a log file where problems are recorded and usually this is the first thing that an Eclipse developer asks for when you report a problem. The log file can be found in a couple of places:
Workspace log - This is the most common location for the log file, It is stored in your workspace in the meta-data directory. Check out
workspace/.metadata/.log.
Configuration log - Sometimes information is recored in the configuration log file instead of the workspace log. (especially if
the workspace hasn't been created yet, there isn't one, or it cannot
be created) Check your configuration area for a configuration log
file. (configuration/.log)
Startup - Occasionally problems happen in the system really early before there is a workspace and before there is a configuration area.
This means that there is nowhere to write the log file so information
is written to the console, See the notes below on running with a
console to get these messages.
So, I now know what to save from nightly builds. What about when I give something to customers?
For example, I probably want to save debugging information (e.g. PDB).
What else?
We use:
installers
binaries
pdbs
tag of source files
any other source files that might not be in svn - for example config.status
build log
You made me wonder if I'm missing anything important
Compiler and library version information (it may not be part of the build log). Somebody else mentioned the whole binaries.
Linker map file (it can sometimes help the remote debugging of a problem).
Unstripped executable (if on a Unix system you strip it the executable before making it available to clients).
For the SDK releases we do include:
PDB and XML for the libraries (packaged with the latest snapshot of the samples)
Packaged snapshot of sources from SVN (just because we can)
Link to the online documentation (docs are generated from the source automatically)
Trace messages don't necessarily need to be generated by default but the possibility to enable them can be very helpful.
Results and Information generated from ATPs that are run on the build (probably as part of the build process).
