My breakpoints are not used [message #778575]

Hello,

When I modify a source file, the program doesn't stop anymore at the breakpoints located in this source file. I have to do a make clean and recompile everything so that it does work again.

binary file is what build after your compile,it is the one which executes.When you modify your source file your editor cannot notify binary where the breakpoint is in binary(source file doesn't sync with the binary), so you need to sync you source file with binary file for breakpoints

Yes, but I compile again my modified file before debugging.

when you compile,Makefile just compiles the file which you have modified and even the binary of that file , but the problem is your other supporting files (other than source) are linked with your source file and which are not updated with its links , so when you make clean and build it , it will create a new binaries for all the files which completely syncs with your source and other files too..

Actually, the problem seems more complicated.

I tested several releases of gdb, and it doesn't change anything.
I use distcc for compiling. The gcc versions are same, but the CentOS releases are different between my workstation and the distcc server.
I have no problems when compiling everything on my workstation.

I am still investigating...

If you are using distcc for local build it should always generate the same results, but if it is using several machines on network it will surely vary. I'm little less concern about different releases of CentOS from your workstation and distcc server because it doesn't going to make much difference on the result

Why, if the gcc release is same ?

All machines on network must all have exactly the same compiler, headers and libraries installed, their clocks must be in sync, and typically that they must all have the same OS and CPU architecture, then it will produce same results all the time.

some programs which both call themselves "gcc 3.2.1" behave differently, presumably because of vendor patches or because vendors have shipped pre-release code.

I have changed the distcc server so that the OS distribution and gcc are same than the ones on my workstation. And I still have the problem.

I don't understand...

Here is what are the gdb messages in Eclipse CDT :

[color=red]No source file named foo.cpp.

Error in re-setting breakpoint 1: No line 127 in file "///////////////////////////////foo.cpp".

warning: Can not parse XML OS data; XML support was disabled at compile time[/color]
