As the title indicates, macOS' (and other BSDs, I assume) mkdir command does not support the --verbose option. However, the -v short version is supported.

jeremies-mbp:bin jgalar$ ./vlttng -p urcu-master /Users/jgalar/test
# Create LTTng virtual environment
mkdir --verbose -p /Users/jgalar/test
Error: Command exited with status 64

Dear vlttng devs

trying to install popt through the vlttng tool fails since the TAR file on the rpm5 website seems to be in a bad state
or the wget command on my machine doesn't work properly

i ran
vlttng -p popt-1.16 lttng -j 48
which outputs

# Create LTTng virtual environment
mkdir -v -p /home/ec2-user/tools/lttng
mkdir -v -p /home/ec2-user/tools/lttng/home
mkdir -v -p /home/ec2-user/tools/lttng/usr/bin
mkdir -v -p /home/ec2-user/tools/lttng/usr/lib
mkdir -v -p /home/ec2-user/tools/lttng/usr/include
mkdir -v -p /home/ec2-user/tools/lttng/usr/opt
mkdir -v -p /home/ec2-user/tools/lttng/usr/share/java

Fetch sources
mkdir -v -p /home/ec2-user/tools/lttng/src
cd /home/ec2-user/tools/lttng/src
wget http://rpm5.org/files/popt/popt-1.16.tar.gz -O popt-1.16.tar.gz
mkdir -v -p /home/ec2-user/tools/lttng/src/popt
tar -xvf popt-1.16.tar.gz -C popt --strip-components=1
Error: Command exited with status 2

when i downloaded the popt tar file manually it was a HTML file, not a tar file.
This happened also when i downloaded with a browser
in general it seems like the popt pages in rpm5 is broken as many of the other version files are missing (404)

is there a way to use the yum installed popt instead of installing popt in the environment ?
i have popt 1.13 installed on my machine

The dependency on popt was removed in Babeltrace 2.x. However, vlttng still warns that the system version will be used.

Similar to the pip freeze.

It should print everything you need to know to recreate the exact same environment.
Maybe in the form of a command line that can be copy-pasted directly or some MI format that can be passed to vlttng.

The --without-lttng-ust option of the LTTng-Tools configure script was introduced in commit a069e9a.
Before that, --disable-lttng-ust was used.

LTTng-Tools profiles with versions before 2.8 will fail if UST is not included.

dat branche: http://git.lttng.org/?p=urcu.git;a=shortlog;h=refs/heads/stable-0.11

It will be great if lttng can be cross compiled with this tool.

When creating a env with Babeltrace with Python bindings on a Ubuntu, we need to change the PYTHON variable to point to the Python3 binary. As mentionned in the Babeltrace README:

export PYTHON="python3"                                
export PYTHON_CONFIG="/usr/bin/python3-config"

Without those exports, the configure script uses the /usr/bin/python binary which is python2.7 on Ubuntu. The make install target will then installs the Babeltrace module in the
virtenv/usr//lib/python2.7/dist-packages directory rather then in the python3.X directory that we need it to be in.

Here is the env I am using :

vlttng --jobs -p lttng-ust-no-man-pages  \
    -p lttng-tools-no-man-pages \
    -p lttng-tools-master \
    -p lttng-ust-master \
    -p babeltrace-stable-1.4 \
    -p babeltrace-python \
    /root/virtenv

If you are not on Ubuntu you can recreate this issue with this LXD configuration: http://paste.ubuntu.com/23631618/

I am not quite sure how to fix this issue yet but I wanted to create this report to not forget about it.
