Hi,
I have been trying to build a hello world with nvcc.
nvcc -g file.cu
There are know compilation erros reported. And the executable runs fine without any issues.
But once i pass optimization options it reports a host of compilation errors.
nvcc -g -O2 file.cu
error: inline function ‘double fabs(double)’ cannot be declared weak
error: inline function ‘float fabsf(float)’ cannot be declared weak
error: inline function ‘double floor(double)’ cannot be declared weak
…
Tons of others are reported.
These erros come from maths_functions.h file in cuda installation directory
cuda/bin/…/include/math_functions.h
The same errors are reproducible with -deviceemu option also.
Following are the configuration of my machine and Cuda
Linux : 32 bit
Fedora 11
Cuda Version : 2.3
gcc version : 4.4.1
Can’t we pass optimization options through nvcc.
thanks
