Title: compiler/debug problem with adding flag option (no debugging symbols found)
Post by: Tommi on March 12, 2017, 12:50:14 pm
Hello guys,

i've got a problem while trying to debug the program i wrote.

I can't use "watches", after long search i figured out that this is a cause of missing debug symbols.
So i searched how to fix this. Unfortunately i have no idea where and how to add this -g,
cause i use code blocks for the first time and the flag "produce debug symbols(-g)" is not listed in "Settings -> compiler -> compiler flags"

So i tried to add this flag by hand, not working, i add it in "other compiler options" and just receive the message:

Code
||=== Build: Debug in Complexe_rechnung (compiler: Borland C++ Compiler (5.5, 5.82)) ===|
||Error E2074: Value after -g or -j should be between 0 and 255 inclusive|
||Error E2075: Incorrect command line option: -g|
||=== Build failed: 2 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

I'm using Win7 64bit
Code::Blocks 16.01

Thanks for your help!

Post a full re-build log.

Edit: I do NOT think Code::Blocks supports debugging with Borland Compiler.

I guess u mean this log? Copyed out from "build log" after re-build, as explained in the FAQ

Code

Cleaned "Complexe_rechnung - Debug"

Process terminated with status 0 (0 minute(s), 0 second(s))

Well, that would explain a lot, if Borland is non debug compatible.

EDIT:

This happen, if i add a -g in "Settings -> compiler -> other compiler options"

why do you use bcc and not gcc?

Thanks for the answer! Our Prof. want us to use Borland BCC ....

EDIT:

After a short look it seems that there is no command to creat such a "Symbol Table"? Am i right?

Did you try -v (instead of -g) ?

Well, this option is listed as "debug on, inline expansion off", unfortunately i can't switch from "Release" to "Debug" without getting this error message:

Code
Error: Unresolved external '_strtod' referenced from D:\PROJEKTE\CODE_BLOCKS\COMPLEXE_RECHNUNG\OBJ\DEBUG\INPUT.OBJ

in fact string.h is included. In "Release" mode this error doesn't appear.

EDIT: Figured the undo of the checkbox out on my own.

EDIT 2:

With the -v the log show

Code
Registered new type: wxString
Registered new type: STL String
Registered new type: STL Vector
Setting breakpoints
Debugger name and version: GNU gdb (GDB) 7.6.1
Starting the debuggee failed: No executable specified, use `target exec'.

I don't know, but is it possible to use gdb for debugging bcc applications?

You messed something up in the project settings... Easiest way would be to create a new project and copy the souces.

Is your application created? What is under Project->Properties->Build target->Debug->Output File name?

It could be possible, that something went wrong. I should creat a new project.
Anyway, i tested the -v option on another pc, with right settings. This option doesn't creat a symbol table, so debug is still not working with -v.

The output file name is "Complexe_rechnung.exe" like the project is called.
Seems the debug is not working with Borland. For simple projects i can still use "printf"  ;D

Thanks for helping anyway, guys :)

For easy debugging of programs created with the borland compiler, you need the borland debugger and this is not supported by C::B
