Hi,
after installation of cudpp to /usr/local, the compilation of jcuda 0.4.2 fails in linking libjCudpp; here is the complete log, Please help:

The error message does not say much, only reporting “Undefined symbols”. Did the CUDPP compilation work without any issues? (At least on Windows, there was some hassle: Even for 32bit, it reuqires a 64bit machine for building). Note that CUDPP has to be compiled as a library, and not as an application.
However, the “Undefined symbols” are all referring to the new hashing functions that have been introduced in CUDPP 2.0 (and no “Undefined symbols” are reported for the other CUDPP functions). CMake should ask for two CUDPP libraries during the configuration: The main ‘cudpp’ library, and the ‘cudpp_hash’ library. Did you specify the latter as an input?
BTW: If you don’t specifically need JCudpp, you may also omit it (in doubt, by just removing the line
add_subdirectory(JCudppJNI)
from the main CMake file)
Hello,
the library cudpp was compiled and installed without any errors.
teh $DYLD_LIBRARY_PATH was modified to add /usr/local/lib where cudpp libraries were installed

OK, I can’t see what might be wrong there. It seems to properly generate the cudpp_hash library.
And when you start cmake-gui for configuring the JCuda build, it should print something like
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_CUDPP_HASH_LIBRARY (ADVANCED)
linked by target "JCudpp-linux-x86" in directory /home/user/Develop/JCuda-All-0.4.2-src/JCudppJNI
CUDA_CUDPP_INCLUDE_DIR (ADVANCED)

CUDA_CUDPP_LIBRARY (ADVANCED)
linked by target "JCudpp-linux-x86" in directory /home/user/Develop/JCuda-All-0.4.2-src/JCudppJNI
Did you change the appropriate entries in the parameter list from
CUDA_CUDPP_INCLUDE_DIR-NOTFOUND —to—> The complete path to the cudpp include directory
CUDA_CUDPP_HASH_LIBRARY-NOTFOUND —to—> The complete path to the cudpp_hash.a file and
CUDA_CUDPP_LIBRARY-NOTFOUND —to—> The complete path to the cudpp.a file
?
(I still don’t understand why it should only complain about the hash-functions, and not about the other CUDPP functions…)
(I’ll probably omit JCudpp in future releases. It’s always a hassle compiling it, and probably not used by many people anyhow. It might be one of several, so to say, “extension” libraries, which could include CUDPP, NPP, and probably others in the future…)
