error: call can not be configured compile error "call can not be configured"

I’m trying to compile a CUDA program that throws “error: call can not be configured”. I’m new to CUDA programming and am not able to figure out what the problem could be. I searched the forums for similar problems, but had no luck.

Following is the CUDA program in brief:

[codebox]#define BLOCK_SIZE 16

int getline(FILE *fp, char line, int max);

void compareSeq(char *fragseqlist_d, int pitch, int *matches_d, int fragcount);

int main(int argc, char *argv)


char **fragseqlist;

int *matches;

char *fragseqlist_d;

int *matches_d;

long fragcount = -1;

int i, width, pitch;

dim3 dimGrid, dimBlock;

/* Code to assign string array to fragseqlist */

/* Allocate host memory */

matches = (int *) malloc((fragcount+1) * sizeof(int));

/* Allocate device memory */

cudaMalloc((void **) &matches_d, (fragcount+1) * sizeof(int));

cudaMemset(matches_d, 0, (fragcount+1) * sizeof(int));

width = 37;

cudaMallocPitch((void **) &fragseqlist_d, (size_t *) &pitch, width * sizeof(char), (fragcount+1));

/* Copy memory from host to device */

cudaMemcpy2D(fragseqlist_d, pitch, fragseqlist, pitch, width * sizeof(char), fragcount+1, cudaMemcpyHostToDevice);

/* Call device function */

dimBlock.x = BLOCK_SIZE;

dimBlock.y = BLOCK_SIZE;

dimGrid.x = (fragcount+1) / BLOCK_SIZE;

dimGrid.y = (fragcount+1) / BLOCK_SIZE;

compareSeq<<<dimGrid, dimBlock>>>(fragseqlist_d, pitch, matches_d, fragcount);

/* Copy device memory back to host memory */

cudaMemcpy(matches, matches_d, (fragcount+1) * sizeof(int), cudaMemcpyDeviceToHost);

/* Free resources */

for (i = 0; i <= fragcount; ++i)






return 0;


int getline(FILE *fp, char s, int lim)


// some code


global void compareSeq(char *fragseqlist_d, int pitch, int *matches_d, int fragcount)


// code for parallel execution


I’m running CUDA 2.1 on Ubuntu 8.04.

I’ll really appreciate any help you could offer. Thanks in advance!

I was able to solve the problem. The problem was that I did not put “global” in front of the forward declaration of the kernel function “compareSeq”.

So instead of:

void compareSeq(char *fragseqlist_d, int pitch, int *matches_d, int fragcount);

It should be:

global void compareSeq(char *fragseqlist_d, int pitch, int *matches_d, int fragcount);

Hope this helps others having similar problems.

Great, I got the same problem with you. Thank you for your solution :)

Thanks ! it helped me.
