### Errors related to undefined reference to `__hcLaunchKernel__***__grid_launch_parm**
|
|
|
|
Some common code practices may lead to hipcc generating a error with the form :
|
|
undefined reference to `__hcLaunchKernel__ZN15vecAddNamespace6vecAddIidEEv16grid_launch_parmPT0_S3_S3_T_
|
|
|
|
To workaround, try:
|
|
- Avoid calling hcLaunchKernel from a function with the __host__ attribute
|
|
__host__ MyFunc(…) {
|
|
hipLaunchKernel(myKernel, …)
|
|
- Avoid use of static with kernel definition:
|
|
static __global__ MyKernel
|
|
- Avoid defining kernels in anonymous namespace
|
|
namespace {
|
|
__global__ MyKernel …
|
|
- Avoid calling member functions
