Coz install fails on CentOS8 Stream

[michaelcordero]

Building from source:

Tried to run the command in the benchmarks directory:
cmake . && make && cd ../..

and got:

fatal error: coz.h: No such file or directory
#include "coz.h"

Unfortunately, you can't build Coz that way. Please follow the instructions given here:

https://github.com/plasma-umass/coz#building-coz-from-source

I just followed them on Ubuntu and everything works as anticipated.

Full instructions copied here:

Building Coz From Source

To build Coz from source, you will need:

• A copy of the source code for this project
• A compiler with C++0x support (clang++ or g++)
• A Python interpreter (Python 3.x is required)
• OPTIONAL: for building the profiler viewer, you need NodeJS and npm -- sudo apt-get install nodejs npm

Once you have all dependencies in place, build Coz with CMake. On Debian-based distributions, the following commands should take care of the entire process:

sudo apt-get install build-essential cmake docutils-common git python3 pkg-config
git clone https://github.com/antoyo/libelfin && cd libelfin && make && sudo make install && cd ..
git clone https://github.com/plasma-umass/coz && cd coz && cmake . && make && sudo make install && cd ..

Next, you need to change the "perf_event_paranoia" level so Coz can run.

sudo sh -c 'echo 1 >/proc/sys/kernel/perf_event_paranoid'

Now you can test Coz. Build the benchmark suite and run one of the benchmarks (the SQLite3 benchmark takes a while to build).

sudo apt-get install libbz2-dev libsqlite3-dev
cd coz/benchmarks && cmake . && make && cd ../..
coz run --- ./coz/benchmarks/toy/toy

Finally, use the Coz viewer to see the results. This command will open up a browser tab, from which you will need to load the file profile.coz.

How can you close this as completed? Those instructions maybe work on Debian-based distributions, not on Fedora/RHEL/CentOS. If Coz does not support the other family of Linux distros that's fine. (I tried to translate them to dnf install btw, but to no avail. The code snippet I listed is how far I got in the installation. I of course ran the previous commands.)

[emeryberger]

I apparently misread your report as just having run cmake . && make && cd ../..; apologies. I'll see if I can install another distro locally to test.

Any updates on this? I'm also trying to build with CentOS Stream 8.

I'm trying to install on Fedora. libelfin installed just fine through make && sudo make install but cmake . fails for coz afterward with the below error (and pkg-config does not find libelf++), though I can verify that /usr/local/lib/libelf++.so exists. Is there a step missing?

$ cmake . && make

Same failure on Fedora 43. This helped:

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

This is probably because libelfin got installed into the wrong place (not in /usr/local/lib64/pkgconfig).

The warning from cmake can be fixed by this:

diff --git a/cmake/Findlibelfin.cmake b/cmake/Findlibelfin.cmake

(following the example here: Kitware/CMake@56d949f)

Sounds like it'd be better to fix this in libelfin, because there is also an error about libdwarf++ not being found, unless I do export LD_LIBRARY_PATH=/usr/local/lib
