[Xenomai-help] Compiler Options

Hi all,
 
I start by apologising for asking what I imagine is a very basic question but it's been driving me nuts all day!  I am currently trying to build and compile one of the sample programs - msg_queue.c.  I'm using the Code::Blocks IDE with GCC underneath it to compile the program.  I have linked in the include directory /usr/xenomai/include but when I compile and link my code I get a load of 'undefined reference' errors relating to all of the xenomai functions.  On my old RTAI setup I have never had to link explicitly to any libs only include header files - what am I doing wrong with xenomai? 
 
My setup is 2.6.27 kernel, Xenomai latest stable, Ubuntu 8.10
 
Apologies again for what I imagine is a very simple question, but it's driving me nuts!
 
Thanks for your help,
 
Steve

I haven't compiled the msg_queue.c example, but i do use the native skin
with rtdm under Code::Blocks with
Ubuntu 8.04.

To use the Xenomai realtime framework in  Code::Blocks IDE,

1. Add these commands to "Project build options", "Compiler settings",
"Other options"

`/usr/xenomai/bin/xeno-config --xeno-cflags`
`/usr/xenomai/bin/xeno-config --xeno-ldflags`

 [you can type the commands on the command line without the apostrophes to
get an idea of the output]

2. Under "Project build options", "linker settings" add libraries as
required

eg native, rtdm ...

[See /usr/xenomai/lib for available libraries]

3. Under "Project build options", "Search Directories", "Linker" add

/usr/xenomai/lib


Hope this helps to get you going

Keep well
Vicki

Try /usr/xenomai/bin/xeno-config { --xeno-cflags, --xeno-ldflags, etc. }
