Hello,
I have been trying to compile the example (without any editing) from Michael Wolfe’s article(Account Login | PGI ), but, I got error when executing the saxpy_test_data target in his Makefile. Here is the error message from pgc++ 13.2 compiler:
$ make saxpy_test_data
pgc++ -fast -acc -Minfo=accel -c saxpy.cpp
_Z5saxpyifPfS_:

Compilation terminated.
make: *** [saxpy_main_data.o] Error 2
The saxpy.cpp was compiled sucessfully. But, pgc++ 13.2 met problem with iostream ? How to solve this? Any suggestion are welcome.
Thank you!

Hi Minh,
This is an odd error and seems to be a problem with your installation. Can you check that the iostream file exists and that you have read permissions? Also, what version of Linux are you using?
$ ls -l /opt/pgi/linux86-64/13.2/include/CC/iostream
-rw-r--r-- 1 colgrove sw 2751 2013-03-04 08:21 /opt/pgi/linux86-64/13.2/include/CC/iostream
Note that you may need to change the root PGI directory, “/opt/pgi”, to match how it’s installed on your system.

Hi Mat,
Thanks for reply. I have checked my permission to iostream header file.
-rw-rw-r-- 1 mw445520 install 2751 Feb 11 16:14 /rwthfs/rz/SW/PGI/PGI_13.2_SCIENTIFIC_64/linux86-64/13.2/include/CC/iostream
I use Scientific Linux release 6.3 (Carbon).
I have tried with -I to include the CC folder in compiling command, but it failed to link the object files.

Is there any environment variable which I need to set?
Sorry, I am new to pgi compiler.

Hi Minh,
This seems to be some type of installation issue. Do you mind sending this issue to PGI Customer Service (trs@pgroup.com )? They’ll be better to help with this issue.
Best Regards,
Mat
