lcutil Where is this file?

On compilation of the BlackScholes code, I get the following message.

/usr/bin/ld: cannot find -lcutil

Now, I have compiled this code before on different systems so I know it compiles.

Where is -lcutil.

Is it in the …/common/inc directory?

Is this the lcutil.h file?

I cannot do a full search on the remote computer and grep (to search for this file) is not helping.

I gave the the answer to this in your other thread. It is a library. It will be here:

avidday@cuda:~$ ls ~/NVIDIA_GPU_Computing_SDK_3.0/C/lib/

libcutil_x86_64.a  libparamgl_x86_64.a  librendercheckgl_x86_64.a

Hello,

The -lcutil flag is for the linker, not the compiler, so it’s not in the inc/ directory but in the lib/ one (usually). As a rule of thumb, adding -lfoo to linker’s flags means that it should be linked with a file named libfoo.a (or libfoo.so). So just look for libcutil.a for instance.

I do not have a version of libcutil.a on my pc hard disk. I found file that might work. Here is the latest output:

errol@fermi:~/NVIDIA_GPU_Computing_SDK/C/lib$ pwd

/home/errol/NVIDIA_GPU_Computing_SDK/C/lib

errol@fermi:~/NVIDIA_GPU_Computing_SDK/C/lib$

As you can see the file is libcutil_i386.a. it is very similar to libcutil.a with an added i_386 at the end. It does not work as you can see above.

Adding the directory on the include list has no effect, it still cannot find -lcutil.

I did try copying libcutil_i386.a to -libcutil.a and got a different set of errors when I compiled. I am not showing those.

Someone on the forum simply renamed libcutil_i386.a to libcutil.a and they said it worked.

I am still not sure what is wrong. In the 3.0 32 bit CUDA where should the libcutil.a file be?

Try -lcutil_i386 instead of -lcutil
