Hello!

I am trying to install the Accelerad by source.

I have already download the NVIDIA-OptiX-SDK-5.1.0-linux64_24109458.sh and I have run it, in order to have the NVIDIA-OptiX-SDK-5.1.0-linux64 folder on my Desktop.

When I download the folder with the source code, I have compiling problems in the src/rt folder. (I have already change the path in CMakeLists.txt there, to the correct path of my NVIDIA-OptiX-SDK-5.1.0-linux64 folder so to recognize the Optix libraries).

The problem is the following:

gcc -I../common -L../lib -O2 -Dlinux -D_FILE_OFFSET_BITS=64 -L/usr/X11R6/lib -I/usr/include/X11 -DNOSTEREO -o ./rtrace rtmain.o rtrace.o duphead.o persist.o ../lib/libraycalls.a ../lib/libradiance.a -lrtrad -lm

duphead.o: In function `openheader':

duphead.c:(.text+0x4a): warning: the use of `mktemp' is dangerous, better use `mkstemp' or `mkdtemp'

rtmain.o: In function `main':

rtmain.c:(.text.startup+0xb74): undefined reference to `printRayTracingTime'

rtmain.c:(.text.startup+0xc71): undefined reference to `printRayTracingTime'

rtrace.o: In function `rtrace':

rtrace.c:(.text+0xe29): undefined reference to `computeOptix'

collect2: error: ld returned 1 exit status

make: *** [rtrace] Error 1

And indeed when I check for example at the file rtrace.c file I find this:

extern void computeOptix(const size_t width, const size_t height, const unsigned int imm_irrad, const double alarm, RAY* rays);

but I do not find the code of this function.

How can I fix it?

Or if I can't how can I find the source code of those finctions?

Thank you,

Eva

Hi Eva,

Are you using CMake? I have not updated any of the other build scripts included with Radiance, so at the moment CMake is the only way to set up the Accelerad project to compile.

Within src/rt/CMakeLists.txt, you'll see that rtrace is built with a number of extra source files and libraries:

add_executable(rtrace rtmain.c rtrace.c duphead.c persist.c ${ACCELERAD_rtrace_files})
target_link_libraries(rtrace ${ACCELERAD_LIBRARY} ${optix_LIBRARY} ${CUDA_CUDART_LIBRARY} raycalls radiance rtrad)

Your gcc command does not include any of the files contained in the lists ${ACCELERAD_rtrace_files}, ${ACCELERAD_LIBRARY}, ${optix_LIBRARY}, or ${CUDA_CUDART_LIBRARY}. That explains your undefined references. Make sure that these files are part of your command. The easiest way to do this is to run CMake.

Hello,

no I tried to build it with the command ./makeall install (as I show in the README.txt file).

I tried to run the command 'cmake .' in every directory I have CMakeLists.txt and then run the Makefile (make) but I still do not get the executables I want (executable of rcontrib for example).

Everything I found about building the source code of Accelerad was talking about running the './makeall install' command.

Is there any clear guide for building it with cmake?
Or could you please tell me the correct way, because with the way I tried I did not achieve it.

Thank you,

Eva

Hi Eva,

There are many resources you can use to learn about CMake. It is helpful to have some knowledge of it before compiling Accelerad. For Windows and Mac, you can follow the instructions on the Daysim site for the most part. For Linux, you can do it as follows:

git clone https://github.com/nljones/Accelerad.git

mkdir AcceleradBuild

cd AcceleradBuild

cmake ../Accelerad

make

Note that CMake is only called on the top level Accelerad directory and is called from outside of that directory.

Accelerad is a fork of Radiance and attempts to deviate as little from Radiance as possible. As such, the README that you see on Github is currently the Radiance README file. It's instructions will not work for Accelerad.

Hello,

I typed the commands below, but Accelerad is still not built.

The error message is :

CMake Error at src/rt/CMakeLists.txt:133 (find_package):

By not providing "FindOptiX.cmake" in CMAKE_MODULE_PATH this project has

asked CMake to find a package configuration file provided by "OptiX", but

CMake did not find one.

Could not find a package configuration file provided by "OptiX" with any of

the following names:

OptiXConfig.cmake

optix-config.cmake

Add the installation prefix of "OptiX" to CMAKE_PREFIX_PATH or set

"OptiX_DIR" to a directory containing one of the above files. If "OptiX"

provides a separate development package or SDK, be sure it has been

installed.

-- Configuring incomplete, errors occurred!

I have changed the path to the correct NVIDIA-OptiX-SDK-5.1.0-linux64 folder and I cannot understand why it is not working.

I cannot find a CMAKE_PREFIX_PATH in the CMakeLists.txt.

Do I have to store somewhere specifically the Radience folder too?

Thank you,

Eva

Hi Eva,

CMAKE_MODULE_PATH is set in src/rt/CMakeLists.txt line 130, immediately before the call to find_package. In the unedited version, it will look for this path:

~/NVIDIA-OptiX-SDK-3.9.2-linux64/SDK/CMake/FindOptiX.cmake

I understand that you have edited the path to the OptiX SDK folder and have installed it in a different location (your desktop). Can you check that FindOptiX.cmake exists and that you have entered the correct path to find it?

You may save yourself some difficulty by using the configuration that was already set in the CMakeLists.txt file: Install OptiX 3.9.2 and save it in the default location (not your desktop). Once you know it is working, then you can experiment with changes.

Hello!
Unfortunatelly I have not achieved it yet. The folder is in the same location as mentioned in the src/rt/CMakeLists.txt.
Now whaen I type cmake ../Accelerad I get this error:

CMake Warning (dev) at src/rt/CMakeLists.txt:336 (get_target_property):
