 HIP codes can be compiled as well using the `hipcc` AMD compiler:
 ```
-hipcc --offload-arch=gfx90a streams.cpp
+hipcc --offload-arch=gfx90a  `CC --cray-print-opts=cflags` <source>.cpp `CC --cray-print-opts=libs` 
 ```
-The flag `--offload-arch=gfx90a` indicates that we are targeting MI200 GPUs.
+The flag `--offload-arch=gfx90a` indicates that we are targeting MI200 GPUs. If the code uses some libraries we need extract from the `CC` wrapers. This is doen via the flags `CC --cray-print-opts=cflags` and  `CC --cray-print-opts=libs`.
 
+A more elegant solution would be to use:
+```
+export HIPCC_COMPILE_FLAGS_APPEND="--offload-arch=gfx90a $(CC --cray-print-opts=cflags)"
+export HIPCC_LINK_FLAGS_APPEND=$(CC --cray-print-opts=libs)
+
+hipcc <source.cpp>
+```
+This is helpful when using make.
