Use GNUARM tool chain (arm-elf-) may occur when this error.
May be due to:
a) Use-mthumb-interwork compiled. s
b) compile. c generated. o in the link on. s generated. o file in front of the
Generally need to press the main menu Project-> Clean ...
Makefile dependency mechanism may result in part. O not cause the error changes
CDT determine whether the debug version of elf:
If you are creating a pure Makefile project requires the project properties -> C / C + + Build-> Settings in check the Elf Parser
While ensuring Makefile to compile each. O use-g3-O0 (third level debugging, the zero level optimization)
As both build and run the vba is difficult to judge the rom gba is normal (for example, some missing. O files)
Some ways to determine:
Start with a relatively high CPU when the screen is white layer model viewer can not see what is
Hou occur when debugging Source not found the problem:
Mode debugging using gdbserver debugger and found that this situation can not add a direct result of the breakpoint.
Observed Debug window, find the path name changed because the original C: \ xx \ xx into \ xx \ xx \ xx.
CDT do not know which disk partition should be to find. C file.
The solution is to Debug Configurations-> Source-> Add-> Path Mapping Add Mapping.
For example, debugging code in the D drive, on the set \ maps D: \
Added: If you open the same port more than 55,555 debugging causes errors
So, step through attention to a single instance of the run before.
Also, select gdbserver debugger, select the tcp 55555 port
And manually specify the arm-elf-gdb.exe.
Debugging before opening vba, for example, start with a batch VisualBoyAdvance-SDL
@ Echo off
set DEBUG_PATH = D: \ software \ mingwdev \ gba \ gbadev
set DEBUG_ELF = step2.elf
set DEBUG_FLAGS =- Gtcp
% DEBUG_PATH% \ common \ bin \ VisualBoyAdvance-SDL.exe% DEBUG_FLAGS%% DEBUG_PATH% \% DEBUG_ELF%
@ Echo on
Then double-click the Start CDT.
Or refer to the official testing method http://vba.ngemu.com/faq.shtml .
1) http://akkera102.sakura.ne.jp/gbadev/ the Step 2
I offer Step 2. On the basis of the source code written in Makefile, used for CDT debugging.

Although no expert in this Makefile to write a technical content, but after all upgraded (for compiling. O files need to be individually specified)
2) I compiled with GNUARM tool chain, because there is no specific gba GNUARM development libraries and tools, you can take that from devkitPro.
For example gbafix.exe:
3) run the CDT environment variables used to set the batch is
@ Set path =% cd% \ eclipse-cpp-galileo-SR2-win32 \;% path%
@ Set path =% cd% \ devkitPro \ bin;% path%
@ Set path =% cd% \ GNUARM \ bin;% path%
