• Errors related to undefined reference to `hcLaunchKernel*__grid_launch_parm

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
