Configuration for debugging - linux/clang

[Arbalest]

I have been using CodeLite with g++ in the windows environment without problems. I recently set up CodeLite under Ubuntu Linux 12.04 (in a virtual machine) and that work OK as well.

However, after installing and building a simple test program with the clang compiler -- in the Linux environment -- I can't seem get the debugger to work for me. The simple few line program that works in regular run mode. When I press F5 the debugger stuff starts, an output window opens and that is it. I can't single step, etc. Yes, compiler has the "-g" option and the active configuration is debug. The debugger output pane acknowledges that breakpoints are set or cleared. It must be a configuration issue or something simple, right? But what?

For what it's worth, I installed everything from binaries rather than build anything.

Sorry, I thought that since it was likely a configuration problem that I had already included all the relevant information. Also, I realize that this is not the latest version of CodeLite. But, again since it seemed like a config issue...

CodeLite: V2.8.0.4537
GDB: 7.4-2012.04
Clang: 3.1

OS: Unbuntu 12.04, under VMware

Self Compiled: NO, for nothing

Debug Log: below, but the relevant line seems to be this:

(Note, the program is a just a bit more than hello world, and it does run properly without the debugger.)

DEBUG>>00000219^error,msg="During startup program exited with code 1."

Indeed, your codelite version is quite old. I am not sure its configuration issue as it should work with the default settings.
Please try to upgrade your codelite as suggested here:

http://codelite.org/LiteEditor/Repositories#toc1

I suspect that it will solve your problem

THANKS! That did solve the problem.

One curiosity though: When I was using the previous version of CodeLite,
the compiler complained that it did not recognize the switch -std=c++0x

So, in Workplace > Active Project Settings, I changed it to -std=c++11
per the LLVM site documentation. After the CodeLite upgrade the compiler is
complaining about the -std=c++11 switch so I had to change it back to -std=c++0x.

That had me worried that I had somehow downgraded clang.
But /usr/bin/clang++ --version does indicate that it is version 3.1.

I know this is not a CodeLite issue.

[Arbalest]

Maybe I spoke too soon. After upgrading to clang 3.2 the build process is trying to include gcc headers and that results in errors.

Again, I know this is a user issue rather than a codelite issue but I have not found a possible cause for this after carefully looking at the information in this site. In fact I see this in older clang boards/fora so I will pursue it there mainly. Anyway, the error is

/usr/include/wchar.h:40:11: fatal error: 'stdarg.h' file not found


Rather than ask directly about this, I want to clarify the role (and differences) among the following configuration settings:

Settings > Build Settings > [compiler] > Compiler Switches (is this for help, or some tool tip type stuff?)

Settings > Build Settings > [compiler] > Compiler Options (although this looks like it would be for the actual settings it appears informational as well)

Workspace > Active Project Settings > Common Settings > Compiler (this seems to be the actual settings that are used by the compiler).

[eranif]

Your problem is clang compiler. You need to fix this.

Settings > Build Settings > [compiler] > Compiler Switches

Usually, in 99% of the cases you should not modify it. It contains the macros that used by codelite to generate makefiles cross compilers, again - you should not need to change it

Settings > Build Settings > [compiler] > Compiler Options (although this looks like it would be for the actual settings it appears informational as well)

This is a _global_ compiler options. It will affect all workspaces. You can add flags here that will be added to all of your projects

Workspace > Active Project Settings > Common Settings > Compiler (this seems to be the actual settings that are used by the compiler).

Not only. They are used in conjunction with the global ones. In the global settings (Settings -> Build Settings ..) you affect all workspaces and projects. While this affects only the current project (actually, only the current build configuration)
