Hi~~
#include <cuda.h>
{
unsigned char* pArray;
int size = 100 * 100 * 4;
cudaError error = cudaMalloc(&pArray,size);
size_t offset = 0;
error = cudaBindTexture(&offset,tex,pArray,size); //Here returns 'invalid texture'
error = cudaUnbindTexture(&tex);
cudaFree(pArray);
return 0;
}
And it was compiled by the following command:
However, the cudaBindTexture function forever returns InvalidTexture. How can I resolve this problem? thanks!

Your code works for me, no errors.
I compiled it with nvcc test.cu -I/usr/local/cuda (linux)
Hi~~
here is my test program:
include
texture tex;
int main()
{
unsigned char* pArray;
int size = 100 * 100 * 4;
cudaError error = cudaMalloc(&pArray,size);
size_t offset = 0;
error = cudaBindTexture(&offset,tex,pArray,size); //Here returns ‘invalid texture’
error = cudaUnbindTexture(&tex);
cudaFree(pArray);
return 0;
}
And it was compiled by the following command:
“$(CUDA_BIN_PATH)\nvcc.exe” -ccbin “$(VCInstallDir)bin” -c -arch sm_13 -D_DEBUG -DWIN32 -D_CONSOLE -D_MBCS -Xcompiler /EHsc,/W3,/nologo,/Wp64,/Od,/Zi,/RTC1,/MTd -I…/SDK/CUDA/include -I…/ -I…/Include -I…/GPU -I./ -o $(ConfigurationName)\main.obj $(SolutionDir)\cudaTexTest\main.cu
However, the cudaBindTexture function forever returns InvalidTexture. How can I resolve this problem? thanks!
With this error, you might want to check if you are compiling for the correct hardware architecture, i.e. not computing for sm_11 with sm_10 hardware.
