I’m using a Linux license to remote debug a remote linux program. When I start debugging and set a breakpoint in the multi-threaded application, VS2012 cannot find the current stack frame in a loaded module. The source cannot be shown for this location.

I’m using VGDB 3.1, Windows 7, Visual Studio 2012, Linux target with GDB 7.2-52

This is the log file:

Hi,

Looks like gdb cannot find the file for the frame, each of the frames below without the file defined cannot find the source file.
```

```
Translated through c++filt, the mangled function names are (in order of appearance):
```
Lib::ImgProc::CLightBar::DetectEdgesFast(Camera::TImageInfo*), Lib::ImgProc::CLightBar::DetectEdges(Camera::TImageInfo*), Application::CApplication::ThreadMain(), Application::CApplication::ThreadMain_Static(void*)
```
.

Find out where these functions are defined and why those files were compiled without debugging symbols for GDB (GCC flag -ggdb). Then recompile them with debugging symbols to be able to set breakpoints in those files.

Hi Ket,

Thanks for your fast reply. These files already have debug symbols. The following makefile options are set:

Makefile Debug symbols:
Lib::ImgProc::CLightBar::DetectEdgesFast(Camera::TImageInfo*) :
$(BINARYDIR)/LightBar.o : ../Lib/ImgProc/Src/LightBar.cpp $(all_make_files) |$(BINARYDIR)
$(CXX) $(CXXFLAGS) -c $< -o $@ -MD -MF $(@:.o=.dep) Lib::ImgProc::CLightBar::DetectEdges(Camera::TImageInfo*) :
$(BINARYDIR)/LightBar.o : ../Lib/ImgProc/Src/LightBar.cpp $(all_make_files) |$(BINARYDIR)
$(CXX) $(CXXFLAGS) -c $< -o $@ -MD -MF $(@:.o=.dep) Application::CApplication::ThreadMain() :

Hi,

The flags look to be set correctly. Firstly, are you building and debugging on different machines or using a cross-compiler?

Try the following:
1. Start debugging, pause the debugging or stop at a breakpoint.
2. Enter into the GDB Session window for each of the function names:
```
info line 
```
Copy the responses here.
3. Enter into the GDB Session window:
```
info sources
```
Are the source files for these functions listed there?

If the functions cannot be found or the source files are not listed, then gdb cannot find debugging symbols for these functions/files. Then run objdump for your project executable on the Linux machine to see if the debugging symbols are there (source code lines for the functions). Use the following command, and then look into the result to see whether these functions have symbols:
```
objdump -d -S 
```
You can also run the same command on individual o files, the symbols should be present in both the o files and the executable.

Hi ket,

Yes I’m building and debugging remotely on a different Linux machine.

GDBSession can’t find a function line, see the message:
info line int i = mPixel2MM.Initialise(((char *)CPixel2MMap::STR_INI_FILE.c_str()), ((char *)CPixel2MMap::STR_INI_SECTION.c_str()));
&”info line int i = mPixel2MM.Initialise(((char *)CPixel2MMap::STR_INI_FILE.c_str()), ((char *)CPixel2MMap::STR_INI_SECTION.c_str())); n”
&”Function “int i = mPixel2MM.Initialise(((char *)CPixel2MMap::STR_INI_FILE.c_str()), ((char *)CPixel2MMap::STR_INI_SECTION.c_str()));” not defined.n”
Function “int i = mPixel2MM.Initialise(((char *)CPixel2MMap::STR_INI_FILE.c_str()), ((char *)CPixel2MMap::STR_INI_SECTION.c_str()));” not defined.
-var-create: unable to create variable object

info sources shows the file of the source function :

I don’t know where to find the problem, but it seems it cannot find the source of some funtions in a file and other function he can find in the same file. 😮

Hi,

According to the log you posted, GDB can find the symbols for Application::WidthMonitor::CApplication_WidthMonitor class and cannot find symbols for Lib::ImgProc::CLightBar::DetectEdgesFast(Camera::TImageInfo*).
Please check whether the Lib::ImgProc::CLightBar::DetectEdgesFast(Camera::TImageInfo*) function (can be also mentioned as _ZN3Lib7ImgProc9CLightBar11DetectEdgesEPN6Camera10TImageInfoE) contains the source code in the disassembly file. If no, please run objdump on the .o file corresponding to the cpp file containing the Lib::ImgProc::CLightBar::DetectEdgesFast(Camera::TImageInfo*) function and see whether the source is displayed when dumping the .o file.

Please note that when running the “info line” command you should put the function name, not the function calling statement, e.g.:
```
info line Lib::ImgProc::CLightBar::DetectEdgesFast
```
The “info line” command will display the source line number that corresponds to a given function and can be used to determine whether the source line information is available for the given module.

Hi,

I have changed the location of DetectEdgesFast to the Application_WidthMonitor class. I can debug function like ProcessImage(), but i can’t debug DetectEdgesFast() of same class Application_WidthMonitor.
When I call info line, the gdb session can’t find the function:
info line DetectEdgesFast
&”info line DetectEdgesFastn”
&”Function “DetectEdgesFast” not defined.n”
Function “DetectEdgesFast” not defined.

When I search in the objdump of application_withmonitor.o I found the following that looks like he can find the symbol:

Hi,

When using info line, please use the full name including the namespace and class, otherwise the function cannot be found. If you changed the location to the CApplication_WidthMonitor class, then you probably need to use the following command:
```
info line Application::WidthMonitor::CApplication_WidthMonitor::DetectEdgesFast
```
The objdump you have included shows that there are symbols for the CApplication_WidthMonitor::ProcessImage(TImageInfo* apImageInfo) function, but it does not show the symbols for the DetectEdgesFast function. Having a call to DetectEdgesFast inside another function does not mean that there are symbols for DetectEdgesFast. Please find where the DetectEdgesFast function is defined inside the objdump of the o file.

Hi Ket,

Sorry for posting the wrong info. For now the info line works and result in the following:

info line Application::WidthMonitor::CApplication_WidthMonitor::DetectEdgesFast
&”info line Application::WidthMonitor::CApplication_WidthMonitor::DetectEdgesFastn”
No line number information available for address 0x804c190 <_zn11application12widthmonitor25capplication_widthmonitor15detectedgesfastepn6camera10timageinfoe>
OK

Here is the DetectEdgesFast function in Application_WidthMonitor.o:

Disassembly of section .text._ZN11Application12WidthMonitor25CApplication_WidthMonitor15DetectEdgesFastEPN6Camera10TImageInfoE:

Hi,

Based on the info line command, gdb cannot find the function source file. However, based on the o file, the symbols of the function are there. Now run the objdump command on your executable, not the o file, look if symbols for CApplication_WidthMonitor::DetectEdgesFast are present:
```
objdump -d -S 
```
If yes, this could be a GDB bug. If no, the symbols are discarded during your build process and analyzing the exact commands ran to build the executable from the .o files should provide enough clues.

Do you got a solution for this GDB bug?

Hi,

Try updating your gdb to a newer version, if there is no built newer version available, then build one from the latest sources (version 7.6 is latest currently).

Hi Ket,

Ii already had build the newest version of GDB, I am using version 7.6.

Hi,

In that case try understanding what causes the problem.

You say that you can set breakpoints and see the source of other functions in the same file, stop the execution at some breakpoint and try the info line command on all the other functions in the file DetectEdgesFast is declared. Is source for all the other functions found, is there a pattern?

Secondly, try renaming the DetectEdgesFast function to something else.

Last but not least, is your gdb and gcc compatible i.e. is gcc adding symbols that gdb can understand? Make sure that your gcc and gdb are meant for the same target and that their versions are roughly the same age i.e. not that the gdb is newest and gcc is ancient.

Hi Ket,

Before I want to update GCC , I updated the bin-utils (ld linker).
This fixed my debugging issue, to find the source files while debugging.

I was using ld version 2.20 and updated it to 2.23.

Thanks for all your help!
