[lttng-dev] Errors compiling converted tp file

[Yan Grange]

Hi,

I try to reproduce the examle of tracing an application in user space as present in the documentation. The conversion of the .tp file, which is a copy paste of the example in the docs provides me with many errors…

I am using gcc 4.6.3 on Ubuntu 12.04 (LTS). I have the following lttng-packages installed:
liblttng-ctl-dev			
liblttng-ctl0				
liblttng-ust-dev			
liblttng-ust0				
lttng-modules-dkms			
lttng-tools

Am I doing something wrong or is there some issue with my environment?


The following errors occur:

~/lttng$ lttng-gen-tp hello-tp.tp
