[lttng-dev] FW: LTTNG-Tools-2.1.1 Support for PPC-32Bit/64bit; Unable to Resolve the Dependencies

Mon Apr 22 01:20:15 EDT 2013

Hi Lttng-Support,

I used following commands to compile and install the LTTng on PPC Board::

1. ./configure --host=powerpc-linux CC=/usr/bin/ppc-linux-gcc CFLAGS="-m32 -g -O2"

2. make

3. make install

4. ldconfig


Error Logs for LTTng-Tools-2.1.1 && lttng-ust-2.2.0-rc1 && userspace-rcu-0.7.2::


liburcu & lttng-ust installed but getting below error while trying to make LTTng-Tools

I also tried with the previous version of the tool

liburcu installed but getting below dependencies while trying to configure for lttng-ust

It seems there are many dependencies involved in the installation of the LTTng, some of them are as follows;



kernel image to 2.6.38 or higher


libpotp > 1.13





glib 2.34.0 and some more packages.

Do we have to download and cross compile them all for ppc or we can get some help from standard package managers for the same?

As of now the kernel used in machine is "3.4.3-rt13"

[root at]# uname -a

Linux 3.4.3-rt13 #1 SMP PREEMPT RT Sat Feb 23 09:46:06 CST 2013 ppc ppc ppc GNU/Linux

As per my observations it may take a lot of time to resolve them all as we have to decide all the correct supporting packages

with the correct releases in order to make them work for a particular Linux image, though its easy to resolve it by using

standard package managers in latest Linux e.g. UBUNTU.

Please suggest on the same.
