Problem compiling examples

Accelerated Computing CUDA CUDA Programming and Performance

Hi.

I followed the guide “GettingStartedLinux.pdf” to set up the CUDA environment, but unable to compile the sample codes using “make”. Here is the error:

nitj@nitj-desktop:~$ cd NVIDIA_GPU_Computing_SDK/C/

nitj@nitj-desktop:~/NVIDIA_GPU_Computing_SDK/C$ sudo make

make[1]: Entering directory `/home/nitj/NVIDIA_GPU_Computing_SDK/C/common'

make -C src/boxFilter/ 

make[1]: Entering directory `/home/nitj/NVIDIA_GPU_Computing_SDK/C/src/boxFilter'

/usr/bin/ld: cannot find -lXi

collect2: ld returned 1 exit status

make[1]: *** [../../bin/linux/release/boxFilter] Error 1

make: *** [src/boxFilter/Makefile.ph_build] Error 2

nitj@nitj-desktop:~/NVIDIA_GPU_Computing_SDK/C$

what is this “cannot find -lXi” ??

My environment variables are as follows:

declare -x PATH="/usr/local/cuda/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"

declare -x LD_LIBRARY_PATH="/usr/local/cuda/lib:"

Any inputs ?

-lXi requires for linker to find file called libXi.so.

To be more general - -lXXX tries to find library file called libXXX.so

In my system (Debian 64-bit, mixture of unstable and experimental) file /usr/lib/libXi.so is (according to dpkg):

libxi-dev: /usr/lib/libXi.so

libxi6: /usr/lib/libXi.so.6.1.0

libxi6: /usr/lib/libXi.so.6

So you need to install package libxi-dev.

To avoid problems with other libraries, install packages xorg-dev and mesa-common-dev, which depend on most of the packages for compiling X programs.

For future reference:

dpkg -S NAME

looks for file NAME in all installed packages

apt-cache search NAME

looks for NAME in descriptions of all packages (including non-installed ones)
