pg 7.01 and cygwin environment

Accelerated Computing HPC Compilers Legacy PGI Compilers

Dear all

I try to compile a program package to run under cygwin. I compiled the package under linux -with some problems- , however, with a considerable gain in execution speed. All programs are c++ coded.
Using pgi under windows (not the SUA or SFU version) in the pgi supplied cygwin enironment the following problems and questions occur:

  1. the compiler does not find all the header files in the include dirs. When I simply replace pgcpp with gcc, it works.
  2. Cygwin wants *.a lib files, the windows pgi wants *. lib lib files. There is a wrapper for lib files supplied, but ar creates *.a libs in my programs. Can I simply rename the *.a libs to *.lib? Can I generally switch to *a.libs somehow? The drivers in the pgi/man directory seem to do something like that.
  3. Can I link cygwin gcc generated *.a libs with pgcc files?

Thanks a lot

Hi a_bra,

You will need to pass the drive in a : format.
For example:

% pgcc -Ic:/tmp main.c

/c/tmp wouldn’t work.

  1. Cygwin wants *.a lib files, the windows pgi wants *. lib lib files. There is a wrapper for lib files supplied, but ar creates *.a libs in my programs. Can I simply rename the *.a libs to *.lib? Can I generally switch to *a.libs somehow? The drivers in the pgi/man directory seem to do something like that.

This is the same as (1), if you link with .a , you will need to give a full path to .a unless it is in local directory. I compile: pgcc main.c libme.a and it works just fine.

  1. Can I link cygwin gcc generated *.a libs with pgcc files?

Maybe. Is your gcc from SUA? You can compile using cl and link with pgcc.

Dear Hongyon

Thank you, the path issue is solved.
Could you shortly specify the cl option from quote 3. Is meant for gcc or pgcpp. I did not find it in either.

I have another problem now. I get errors during compilation in the cygwin environment that do not occur for the same code with Linux. I mostly get errors 307, 256 792 and 20, all some definition problems more or less. They seem not to be related to the windows headers. Any idea?

How can I suppress an error? The error_suppress option seems not to work. I tried -error_supress 307 or #307 without any effect.

Thank you

Hi,

You will need to have Microsoft Visual studio to have cl. It is Microsoft C/C++ compiler.

You will need to post the error her as I am not sure what those errors are.

Dear Hongyon

Thanks for the answer

These are the error messages from 2 files I get under cygwin. All this does not happen with Linux.

I would appreciate your help

Hi,

Before I investigate further, I would like to get more information about the application you compile. I assume this is not your own application. Is this publicly available program? What is it? You might want to check with the author if they have ported to windows and have windows version available. From the error below, I am guessing that the version you have is not ported to windows.

Dear Hongyon

Thank you for the reply. Your questions are absolutely o.k, but can I contact you directly for them?

Hi,

Are you them? Of course, we are happy to help if this is a compiler issue.
