OSL 1.2 Compile errors on Ubuntu 12.04

[Thomas Dinges]

Hi everyone,
Firt of all congratulations on the OSL 1.2 release! :)

I compiled OSL 1.1 Trunk in June on my Ubuntu 12.04 system and already then I had several issues. Back then I had to disable accum_test, testshade and shaders. Afterwards I got the libs at least to work with.
Was that not a good idea? If these 3 things are optional, it would be great if there would be a simple On/Of switch in cmake, I could not find one and had to comment several lines.

I tried to compile OSL 1.2 now and again have the same issues, here are the errors and my config:

Thanks in advance,
Thomas Dinges

Can you do a full 

make nuke

make VERBOSE=1 > output.log

and forward that to me?

Also, which version of OIIO are you compiling against?

Hi Larry,
sure, thank you.

Attached the output.log.

I am compiling against a OIIO Trunk revision from June 4th.

Regards,
Thomas

[Thomas Dinges]

Hi again,
after you asked for my OIIO version I compiled fresh libraries of OIIO from trunk. And it seems that fixes a lot! :)

But I am getting these errors now, any idea here? I already found this https://github.com/OpenImageIO/oiio/issues/421 but not sure where to add this -ldl flag, tried in cmake of osl (Linker Flags) but no improvement.

Best regards,
Thomas

Hi, Thomas!

Regarding your "undefined reference to" problem, here's a stripped down
example of how to fix this error in any CMake project:
https://gist.github.com/3595733

I would avoid adding -ldl manually to the linker flags. CMake can do
this for your in a platform independent manner.

I hope this helps.

Best regards,
Konrad

Hi Konrad,
thanks for the link! I managed to compile osl now, thanks a lot!

OSL already has a bunch of these ${CMAKE_DL_LIBS} flags in cmake, but
there was one missing:

src/liboslcomp/CMakeLists.txt, I had to add the ${CMAKE_DL_LIBS} here too.

Larry would that be something to fix in osl itself, or is it platform
specific?

Best regards,
Thomas

You have to edit the following CMakeLists.txt files to add the dynamic
linker target:


diff --git a/src/oslc/CMakeLists.txt b/src/oslc/CMakeLists.txt

-TARGET_LINK_LIBRARIES ( oslc oslcomp oslexec ${OPENIMAGEIO_LIBRARY}
${Boost_LIBRARIES} ${CMAKE_DL_LIB
===============================================================
+TARGET_LINK_LIBRARIES ( oslc oslcomp oslexec dl
${OPENIMAGEIO_LIBRARY} ${Boost_LIBRARIES} ${CMAKE_DL_INSTALL ( TARGETS
oslc RUNTIME DESTINATION bin )



diff --git a/src/libOpenImageIO/CMakeLists.txt
b/src/libOpenImageIO/CMakeLists.txt

-target_link_libraries (OpenImageIO ${Boost_LIBRARIES})
=============================================
+target_link_libraries (OpenImageIO dl ${Boost_LIBRARIES})
