specifying X11 location

radiance-dev
1

Hello,

I am trying to install radiance on Linux 64 (in a docker container based on
https://hub.docker.com/_/amazonlinux/)

When I run ‘makeall install’ I get 10 errors of the following type: *fatal
error: *X11/Xlib.h: No such file or directory

I believe this is because I don’t have X11 installed. I have a /usr/lib64/X11
directory but it is empty.

There is a library for amazonlinux called libX11 (https://aws.amazon.com/
amazon-linux-ami/2017.09-packages/), so I installed it: yum install
libX11-1.6.0.

I can ask what was installed:

sh-4.2# repoquery --list libX11

/usr/lib/libX11-xcb.so.1

/usr/lib/libX11-xcb.so.1.0.0

/usr/lib/libX11.so.6

/usr/lib/libX11.so.6.3.0

/usr/lib64/libX11-xcb.so.1

/usr/lib64/libX11-xcb.so.1.0.0

/usr/lib64/libX11.so.6

/usr/lib64/libX11.so.6.3.0

sh-4.2#

How do I now change the -L option of the rmake command to reflect my
environment?

The current value is ‘-L/usr/X11R6/lib’

I tried changing it to ‘-L/usr/lib64’ but I still get the X11-related
fatal errors.

I also tried copying the libX11 files from /usr/lib/ to /usr/lib64/X11 and
setting -L to '-L/usr/lib64/X11' but I get the same errors.

Have you come across this problem before?

Any suggestions as to how to address the problem?

Thank you in advance for your help.

Hello,

In https://github.com/NREL/Radiance/blob/master/noX11.help I see the
following:

   If you have X11 installed but in a non-standard location, you only need
to edit the rmake script to add the needed -I and -L options.

I think that by 'add the needed -I and -L options." it really means modify
the existing -I and -L options to reflect the location of X11.
Is that right?

In https://github.com/NREL/Radiance/blob/master/makeall#L113 I see

set mach="-Dlinux -D_FILE_OFFSET_BITS=64 -L/usr/X11R6/lib
-I/usr/include/X11 -DNOSTEREO"

Am I right in thinking that I just need to replace /usr/X11R6/lib and/or
/usr/include/X11 with alternative absolute paths, and the build should work?

My X11 installation consists of the following four files:

/usr/lib64/libX11-xcb.so.1

/usr/lib64/libX11-xcb.so.1.0.0

/usr/lib64/libX11.so.6

/usr/lib64/libX11.so.6.3.0

How should I change the -L and -I options. Do I need to have both -L and -I
or just one of them?

Is this what I need?:

set mach="-Dlinux -D_FILE_OFFSET_BITS=64 -L/usr/lib64 -I/usr/lib64
-DNOSTEREO"

When I run makeall install, I am given the opportunity to change the line
interactively. Is that all I need to do, or should I make the change myself
directly to the makeall file?

Thank you in advance for your help.

Philip Schwarz

P.S. If the solution involves setting up symbolic links (preferably not),
can you please go into details? Thanks.

If you're compiling Radiance yourself, you not only need the X11 libs, but also the X11-development libs, as well as a few other build dependencies. Is there something like libX11-dev for Amazon LINUX?

I think you need at least the "xorg-x11-proto-devel-7.7” package, or whatever the current version is. That has at least some of the headers. You may need some other packages, but that’s a place to start.

Might want to try asking on Amazon’s developer forums or Amazon technical support directly, if Amazon offers any.

Hello Axel,

thank you very much! There is such a library: libX11-devel. I
installed it and ran 'makeall install' without editing the -L and -I
options, and the 10 X11-related compilation errors are no longer
occurring.

I'll follow up in a separate email to talk further about this.

Philip

Hello,

should I be concerned about the fact that installing libX11 and
libX11-devel seems to have been sufficient in order to eliminate the
X11-related compilation errors?

I expected to also have to change the -L option to point to /usr/lib64 in
the following

set mach="-Dlinux -D_FILE_OFFSET_BITS=64 -L/usr/X11R6/lib
-I/usr/include/X11 -DNOSTEREO"

That's because I don't have a /usr/X11R6/lib directory (but I have some X11
files in /usr/lib64 instead, due to having installed libX11).
I didn't expect to have to edit the -I option because I do have a
/usr/include/X11
directory, due to having installed libX11-devel.

Thoughts?

Also, our application uses Radiance in headless mode (no UI).
Am I right in thinking that whilst installing X11 is necessary in order to
get a clean build, many of the resulting binaries can be run without X11.

E.g. am I right in thinking that I can run oconv and rtrace without X11?

Is there some resource that can be used to determine which Radiance
binaries rely on X11 and which don't?

Thank you in advance for your help.

No. There’s probably a symlink that’s covering that.

Also, our application uses Radiance in headless mode (no UI).
Am I right in thinking that whilst installing X11 is necessary in order to get a clean build, many of the resulting binaries can be run without X11. E.g. am I right in thinking that I can run oconv and rtrace without X11?

That’s correct. If you want to use any of the X11 programs remotely, you can run an X server on the system you are accessing your Amazon system from.

Is there some resource that can be used to determine which Radiance binaries rely on X11 and which don't?

Mmmm…”ldd” will probably tell you, if the build script uses shared libraries. But only the programs that have graphical interfaces use X11 anyway.

Hi Philip,

as far as I understand you, the aim is to get a minimalistic Radiance rendering node. For that, I would propose to exclude all the X11, tcl-tk and tiff stuff. You will probably not work interactively on the node but get the results transferred to a local work-station, where you could do all file conversion and display work. You may also remove all the example files from the lib directory. The question is how to best implement all this in a makefile, so that you do not get all the errors. I have to admit that the many build systems around in Radiance are confusing... Maybe editing the rmakefiles, and setting up a new target such as "minimal-install" would be a good start.

Cheers, Lars.

Thanks Lars,

If I look at the contents of rad5R1supp.tar.gz
<https://www.radiance-online.org/download-install/radiance-source-code/latest-release/radR51supp.tar.gz>
(I
would look at the equivalent for 5.0, the version I am targeting, but it
doesn't seem to exist - it looks like core and auxiliary files are bundled
together in

rad5R0all.tar.gz
<https://www.radiance-online.org/download-install/radiance-source-code/archived-releases/radiance-5.0/rad5R0all.tar.gz>),
I see the following:

doc 102KB

lib 371 MB

obj 2.6MB

src 9.3 MB

src just contains px/tiff, which you explained I can exclude

doc is just documentation so can be excluded

lib is the large one - what do you mean when you say "You may also remove
all the example files from the lib directory" - can the whole directory be
excluded?

what about the obj directory? You didn't mention it: can all of it be
excluded? It contains the following subdirectories:

alpha

cabin

misc

office

texture

virtual

Also, in a context in which I am only running binaries oconv and rtrace, is
it the case that none of the auxiliary files are needed? If not, which ones
are needed?

Your help with the above would be greatly appreciated.

Thanks,

Philip

Hang on, if you're really only using oconv and rtrace, not only do you not
need libtiff, you don't even need X11 at all. And the obj directory can be
ignored as well, those are all sample scenes and stuff.

Yes, initially at least, we plan to use just oconv and rtrace. We probably
want to use additional binaries in future.

you don't even need X11 at all.

Do you just mean that we could have ignored the X11-related compilation
errors? (we bothered to include X11 libraries at build time to get as clean
a compilation as possible, to be sure that the binaries we get out of the
build are in a healthy state). Or do you mean this implies certain
auxiliary files can be excluded?

And the obj directory can be ignored as well, those are all sample scenes

and stuff.
good to know

@Rob @Lars

"You may also remove all the example files from the lib directory"

The majority, if not all of the files in the lib directory seem to be
example files which we are unlikely to need:

What about these subdirectories of lib (odd: a lib dir within a lib dir) ?

Is there anything in these that is not aimed at providing examples, or that
is otherwise needed to run radiance binaries?

Thanks,

Philip

X11 is just for rvu, the Radiance scene viewer, and holodeck. IMO rvu is very helpful for playing with options and for setting up views to be rendered, but if you're focused on point calcs you really don't need it.

    src 9.3 MB
    
    src just contains px/tiff, which you explained I can exclude
    
    doc is just documentation so can be excluded
    
    lib is the large one - what do you mean when you say "You
     may also remove all the example files from the lib directory" - can the whole directory be excluded?
    
    what
     about the obj directory? You didn't mention it: can all of it be excluded? It contains the following subdirectories:
    alpha
    cabin
    misc
    office
    texture
    virtual
    
    Also, in a context in which I am only running binaries oconv and rtrace, is it the case that none of the auxiliary files are needed? If not, which ones are needed?
    
    Your help with the above would be greatly appreciated.
    
    Thanks,

    Hi Philip,
    as far as I understand you, the aim is to get a minimalistic Radiance rendering node. For that, I would propose to exclude all the X11, tcl-tk and tiff stuff. You will probably not work interactively on the node
     but get the results transferred to a local work-station, where you could do all file conversion and display work. You may also remove all the example files from the lib directory. The question is how to best implement all this in a makefile, so that you do
     not get all the errors. I have to admit that the many build systems around in Radiance are confusing... Maybe editing the rmakefiles, and setting up a new target such as "minimal-install" would be a good start.
    
    Cheers, Lars.
    
    Hello,
    
    should I be concerned about the fact that installing libX11 and libX11-devel seems to have been sufficient in order to eliminate the X11-related compilation errors?
    
    I expected to also have to change the -L option to point to
    /usr/lib64 in the following
    
    set
     mach="-Dlinux -D_FILE_OFFSET_BITS=64 -L/usr/X11R6/lib -I/usr/include/X11 -DNOSTEREO"
    
    That's
     because I
     don't have a /usr/X11R6/lib
    directory (but
     I have some X11 files in /usr/lib64 instead, due to having installed libX11).
    I didn't expect to have to edit the -I option because I do have a
    /usr/include/X11 directory, due to having installed libX11-devel.
    
    Thoughts?
    
    Also, our application uses Radiance in headless mode (no UI).
    Am I right in thinking that whilst installing X11 is necessary in order to get a clean build, many of the resulting binaries can be run without X11.
    
    E.g. am I right in thinking that I can run oconv and rtrace without X11?
    
    Is there some resource that can be used to determine which Radiance binaries rely on X11 and which don't?
    
    Thank you in advance for your help.
    
    Philip Schwarz

Hi Philip,

don't worry about the "healthy state" of the executables. Make sure that you have oconv ("pre-sorting" your geometry), vwrays (generating rays for given projections), rtrace (the fundamental ray-tracer), rpict (a ray-tracer for images), rcalc (a calculator for tabular data), and the various generators (especially gensky). As long as they build, they will do, and you may simply ignore build errors as long as you get what you need.

From the lib directory, you will at least need rayinit.cal. If you are aiming at CBDM, you also need the directional basis definitions according to Klems, Reinhart et al. These are somewhat scattered over directorys, best is to check your particular commands and collect them from the source tree in one central lib-directory which you would include in your RAYPATH. The various .cal-files have descriptions of their intended use included as comment lines, they are useful (e.g. for interpolation, mapping, color conversions) and definitely worth browsing, but not critical for plain ray-tracing.

Cheers, Lars.

Do you just mean that we could have ignored the X11-related compilation
errors? (we bothered to include X11 libraries at build time to get as clean
a compilation as possible, to be sure that the binaries we get out of the
build are in a healthy state). Or do you mean this implies certain
auxiliary files can be excluded?

As far as specifying X11 location; if this is a need – and I have found it
sometimes useful – the usual way this is done is via an X server running on
your desktop system and ssh. The specifics depend on the details of the
desktop system. If it is a Windows system, the inexpensive solution is the
Xming X server and the PuTTY application. This page gives a summary of the
setup procedure: http://www.geo.mtu.edu/geoschem/docs/putty_install.html.
On a Mac, one uses XQuartz and the usual Mac terminal application.
Unix-like systems run X11 natively, and one can simply use ssh from a
window. For all of these, you may have to turn X Windows ssh access on on
your Amazon LInux instance.

I see I didn't make clear that in these procedures ssh sets the DISPLAY
variable on the Amazon Linux instance, so that one need only connect and
ideally everything else just works.
