[Openexr-devel] openexr

Hello,

I’m trying to build and install the openexr libs on ubuntu 14.04. (clean install with QT creator installed )

1) I have downloaded the 2.2.0 libs from openexr.com/downloads

2) Building Ilmbase and openexr is OK.

3) before building OpenEXR_viewer, I have to download some other libs:

3a)I have downloaded CTL from github.com/ampas/CTL

3b) I have downloaded fltk-1.3.3-source from www.fltk.org

3c) I have built both the fltk and CTL libs, this seems to build fine.

3d) Hower, CTL does report an error if I run the “sudo make check” command. part of the output (see CTL.txt for complete build output):

[ 81%] Building CXX object unittest/IlmCtl/CMakeFiles/IlmCtlTest.dir/testExamples.cpp.o

/home/nvdb/exr/CTL/unittest/IlmCtl/testExamples.cpp: In function ‘void testPrintExample(Ctl::Interpreter&)’:

/home/nvdb/exr/CTL/unittest/IlmCtl/testExamples.cpp:77:52: error: ‘memcpy’ was not declared in this scope

memcpy(fData, fDataOrig, dataSize*sizeof(float));

make[3]: *** [unittest/IlmCtl/CMakeFiles/IlmCtlTest.dir/testExamples.cpp.o] Error 1

make[2]: *** [unittest/IlmCtl/CMakeFiles/IlmCtlTest.dir/all] Error 2

make[1]: *** [unittest/CMakeFiles/check.dir/rule] Error 2

make: *** [check] Error 2

address@hidden:~/exr/CTL/build$

???? Question:

???? adding “string.h” to the source files, does fix the problem, however, is this normal that I have to change the source files ?????

????

4) I have troubles with the openexr_viewers-2.2.0:

4a) Next, I get a first error while running ./configure from the openexr_viewer directory .Part of the output (see log1.txt for complete build output):

checking for OpenEXR... no
*** Could not run the OpenEXR test program, checking why...
*** The test program compiled and staticly linked, but did not run. This
*** usually means that the run-time linker is not finding OpenEXR or finding
*** the wrong version of OpenEXR.
***
*** If the linker is not finding OpenEXR, you'll need to set your
*** LD_LIBRARY_PATH environment variable, or edit /etc/ld.so.conf to point
*** to the installed location Also, make sure you have run ldconfig if that
*** is required on your system.
***
*** Flags used by the test:
*** cflags: -g -O2 -pthread -I/usr/local/include/OpenEXR
*** ldflags: -L/usr/local/lib
***

4b) I have added the LD_LIBRARY_PATH to .bashrc

4c) I run again ./configure. Now I get the next error:

checking for pkg-config... (cached) /usr/bin/pkg-config

using pkg-config to set OPENEXR_CTL_CXXFLAGS and OPENEXR_CTL_LDFLAGS:

/usr/bin/pkg-config

OPENEXR_CTL_CXXFLAGS = -I/OpenEXR

OPENEXR_CTL_LDFLAGS = -L

OPENEXR_CTL_LIBS = -L -lIlmImfCtl

checking for OpenEXR... yes

Compiled and ran OpenEXR test program.

checking for OpenEXR_CTL... no

*** Could not run the OpenEXR_CTL test program, checking why...

*** The test program could not be compiled. Is OpenEXR_CTL installed?

*** Check that the cflags (below) includes the OpenEXR_CTL include directory

***

*** Flags used by the test:

*** cflags: -g -O2 -I/OpenEXR

*** ldflags: -L

***

*** You can also run configure with --disable-openexrctltest to skip this test.

The OpenEXR_CTL package could not be found. Will build and install playexr and exrdisplay without ctl support.

If I look at the content of /usr/local/lib/pkgconfig/openEXR_CTL_pc, then I see that all directory are empty:

Prefix =

Exec_prefix=

Libdir =

Includedir=

OpenEXR_includedir=/OpenEXR

4d) The error above is not preventing to build the project

I have run the “make” and the “sudo make” command from the openexr_viewer directory

5) exrdisplay

5a) from a console, I run exrdisplay rec709.exr -> viewer starts up and image looks fine, with the sliders I can change the image.

5b) from a console, I run exrdisplay rec709_YC.exr -> viewer starts up but Image is not ok I only see gray

???? Question ???

?????Is this because the CTL lib has not been found during the build of the openexr_viewer ???

????

6 ) In the openexr_viewer directory, I have opened the configure file and changed it a little bit so that the default directories are used instead of the pkgconfig info.

( I have put the pkgconfig lines in comment (lines 15700-15712).

I have done again :

./configure

Make

Sudo make install

Now, I don’t get errors anymore and the build output reports: CTL support YES (See log3.txt)

7) exrdisplay

However, If I startup the exrdisplay, I get errors that the program can’t find transform_RRT and transform_display_video

If I google these files, I can find the content of the files, but why are these missing in my build?

???? Question ???

?????I don’t think this is normal??? Could it be that I don’t have the correct version of the CTL ??? Where can I find the latest version, or could someone send the *tar.gz to me?

From the lib directory, I can see: libilmCtl.so.1.5.0

????

8) I have added these files manual to the usr/local/lib/CTL

Now the exrdisplay is starting up, but now the sliders on top of the viewer are missing !!?????

What is going on???

Kind regards,

Nick
