[eq-dev] Xubuntu 14.04 2-node local config fails

[Petros.Kataras]

Hi all,

I am trying the latest github version of Equalizer and I am having some
issues when trying to run the examples on a 2-node local config.

Tried both seqPly and eqPly.

More specifically the application node fails with :

7204.Draw0 q/client/glx/windowSystem.cpp:110 1854 Can't load font

I am on Xubuntu 14.04 and the relevant examples run fine with just an app
node.

Has anyone experienced something similar ??

Thanks for any hints.

[Petros.Kataras]

So It appears that this issue was related to an 'un-clean' build of the
library / examples .

I think that this was caused because the project fetched updates from git
but not all of them at once.

i.e I noticed a fast-forward on Equalizer today morning when I first tried
to compile the repo that I had cloned last week and just now by doing a
clean build I noticed a fast-forward on Collage also that didn't happened
earlier today and from the commits I can see that they where updated at the
same point 4 days ago.

Which leads me to the next question:

What would be the recommended way to disable this mechanism ?

Best,

Petros

Use 'make Equalizer-make' target, which will not update source. It needs all the projects configured, i.e., you have to run at least once 'make Equalizer' beforehand.

[Petros Kataras]

Hi Stefan,

thanks for your prompt reply.

Now that we are on the cmake side of things I had a couple of general
questions.

I have some time from the office now to work on the latest eq stuff and
try to see what it would require to rewrite from scratch this wrapper
that exists here since 2009 ( auuutss.. ) but this time based on the sequel.

In order to organize the project for local dev here, ideally I would
like to be able to keep the necessary libs ( EQ, CO, LB etc ) as
separate projects ( something like what the structure of eq and co used
to look back in the day.. :)

Is there a recommended workflow / structure to achieve something like
this or the usage of Buildyard is a prerequisite ??

Buildyard has worked fine for me some times and some times other not.

Right now what I found to work out of the box for me was to clone
Equalizer and make which then caused Buildyard to fetch the dependencies
and build everything but ideally I would like to avoid this and be able
to compile and link the projects individually..

So, is there a recommended way of achieving this and if not what would
be your suggestion ??

Thanks!

Petros

What I do on my end is clone and maintain the various eq libraries in
independent directories. The new versions of the source allow you to disable
buildyard. At that point, you can treat each library as a standard CMAKE
project. Obviously you'd have to maintain any dependencies manually but its
not that bad to be honest, you can do a basic build of LB, CO and EQ just by
having Boost and vmmlib.

What I would like to know is how to disable the auto-pull from the repos
when re-cmaking each of the individual projects :P.

Cheers,

Harris

Any hints on where I can disable this option ?

This would basically be all I need .. Actually this is one of the reasons
that I would like to avoid Buildyard if possible.. I would like to avoid all
optional dependencies and setting of options in favor of something more
straightforward. That would make sense internally as tomorrow maybe someone
else wants/needs to build the project without necessarily having much of
cmake experience or the internals - actual dependencies of EQ.

That could come handy for me also in the future :)!

If you turn on advanced options in cmake-gui, there should be a flag for
DISABLE_BUILDYARD :).

No, Buildyard is not a prerequisite. You can set up the projects independently, install them someplace and the point the downstream's CMAKE_MODULE_PATH there. Ubuntu packages are build this way, for example. In the end you'll do what Buildyard does manually. BY now also has BUILDYARD_BUILD_OPTIONAL which you can set to OFF to get way fewer dependencies build.



Cheers,

Stefan.

'make Equalizer-make' from Buildyard or 'make all' from Buildyard/src/Equalizer.

BUILDYARD_BUILD_OPTIONAL doesn't seem to significantly affect the amount of
dependencies that BY wants to make:

BUILDYARD_BUILD_OPTIONAL OFF:

Building: Collage Equalizer GLStats Lunchbox hwsd pngs vmmlib
[ CMake EqDocs Poppler Qwt TUIO VRPN VTK Wiiuse apitrace
equalizergraphics eyescale eyescalePorts gmock libzmq zeromq zeromqcpp
zmqcpp ]


BUILDYARD_BUILD_OPTIONAL ON:

Building: Collage Equalizer GLStats Lunchbox hwsd pngs vmmlib
[ CMake EqDocs Qwt VRPN VTK Wiiuse apitrace equalizergraphics
eyescale eyescalePorts gmock libzmq zeromq zeromqcpp zmqcpp ]

Actually turning to OFF just adds Poppler to the build :p.

The actual 'make Equalizer' build will only do Lunchbox, Collage and Equalizer.

Yeah that seems to be working although BY still doesn't respect the
architecture flags (trying to force a 64 bit build on it). It seems that I
have to stick with my independent build approach.

Strange, that should work. Whatever you set in BY's CMakeCache gets propagated to all projects. I'm using it to force a 32 bit only build.

The BUILDYARD_BUILD_OPTIONAL worked fine together with make Equalizer.

As far as I see this defaults to a Debug build. Is there a proper way to
enable a Release build ? Right now I am forcing it by explicitly setting
-DCMAKE_BUILD_TYPE=Release on the Buildyard makefile.

Is there a target already set for this ??

Thanks !

Petros

'make release' to configure a release build in Buildyard/Release, then 'make BUILD=Release <target>'.

Hi,

Is there a CMakeLists.txt missing from:

v1.7.2/Buildyard/Build/Equalizer/


in particular, i'm trying to add linking flags (-zmuldefs) to the linking step
(shown in red during the build):

  Linking CXX shared library ../../lib/libEqualizer.so

But they don't turn up during the linking of this lib. I'm wondering whether
it's because there ought to be a CMakeLists.txt file, but it's missing and so
the Makefile is not modified.

with "export VERBOSE=1", and the "/xxxxxx" prefix subsituted to protect the innocent(tm),
make -d reveals:

the flag i'm looking for (-zmuldefs) isn't in there.
I've added "-zmuldefs" to every cmake variable with LINKER in the name,
and even made an LDFLAGS variable with "-zmuldefs". So now i'm wondering
if cmake-gui run from the top build directory is affecting the Makefiles, and
if it is not, then is this because there is a missing CMakeLists.txt file  (?)

Also, when i set CMAKE_VERBOSE_MAKEFILE on in the top cmake-gui operation
(with 'configure' and 'generate' to follow) the build did not report verbosely.

any thoughts?

ah. Still groking cmake & buildyard.. The file

v1.7.2/Buildyard/Build/Equalizer/examples/CMakeLists.txt

made it look like there should be one in the parent dir.

find(1) shows all the CMakeLists.txt files live in ./v1.7.2/Buildyard/src
with the top one in Buildyard dir itself. ok!

btw, is there any reason not to use "cmake-gui" ?
(to configure and generate builds using ./v1.7.2/Buildyard/CMakeLists.txt)

Also, is there an easy way to confirm new CMake compile options are being passed
into packages? (other than with verbose makes & greps etc). can't see -zmuldefs ...

thx! b.

Hi,

There's been a bit of trouble (reported on this list) with
"multiple definition errors" (due to glew v1.9) when building.

I'm happy to report Equalizer v1.7.2 just successfully built with:

media-libs/glew-1.10.0-r2

This version is still considered "unstable" on gentoo, so to install it
you need to first add this to:

/etc/portage/packages.accept

   # allow new version of glew for Equalizer
   media-libs/glew ~amd64

then
