castrophic error: cannot find open source file "include

I am having a problem when I am trying to accelerate my existing c++ code using pgi OpenACC compiler.

When I use an example code it compiles without any problem. For example I used nbody example and it compiled successfully as shown below;

root@prince-300E4C-300E5C-300E7C:/opt/pgi/linux86-64/2016/examples/OpenACC/samples/nbody# pgcc -fast -acc -ta=tesla -Minfo=all nbodyacc.c

PGC/x86-64 Linux 16.10-0: compilation completed with severe errors

But when I use compiler directives to parallelize existing loops in my existing C++ code its poping up the following error ;

oot@prince-300E4C-300E5C-300E7C:/home/prince/ceph_ajou/src/osd# pgc++ -fast -acc -ta=tesla -Minfo=all
“Dedup.h”, line 20: catastrophic error: cannot open source file
#include “include/types.h”

1 catastrophic error detected in the compilation of “”.
Compilation terminated.

Can anyone assist

Hi Prince Hama,

For the first error, you need to add “-Minline” to inline the “bodyBodyInteraction” function into the compute region. Alternately, you could add the “routine” directive to have the compiler create a device callable version of the function. Here’s the flags used in the Makefile:

pgcc -c -DFP64 -fast -Minline check.c
pgcc -DFP64 -fast -Minline -Minfo -acc  -o nbody.out nbodyacc.c check.o

For the second error, the compiler can’t find the types.h header file. For this, you’ll need to add the “-I<path_to_base_inlcude_dir>” flag to tell the compiler where to find the header file. Use the path where the “include” directory is located (most likely “/home/prince/ceph_ajou/” or “/home/prince/ceph_ajou/src”).

Hope this helps,
