SystemC CCI Build Issues

[AmeyaVS]

Hi,

I tried using the SystemC CCI draft release.(cci-0.9.0_pub_rev_20171219.tgz)

Currently the following examples fail to compile:

• ex07_Parameter_Information
• ex16_User_Defined_Data_Type

Please find the failure logs attached.

I have also noticed that the CCI source contains systemc.h (src/cci_core/systemc.h)header file, from a cursory look it looks as if a wrapper around the header file (systemc) from SystemC library.

Would it cause build issues when using SystemC CCI with legacy models which includes the systemc.h header file?

Thanks and Regards,

Hi Ameya,

thanks for the feedback!  Can you please provide the following details:

• Platform (Cygwin?)
• GCC version used
• Logs of verify.pl with -v enabled (to see the full command-lines)

The file cci_core/systemc.h is an internal header which is only included through this path.  A conflict could only occur, should you add cci_core/ directly to the compiler include path (which is not supported), or if you'd install SystemC below cci_core/ (which would be very weird ;-)).  

The errors in ex07_Parameter_Information indeed look like the SystemC installation is not correctly resolved.  For this, the full command-lines would really help.

The error in ex16_User_Defined_Data_Type is indeed a bug (at least before C++14(?)).  The fix is to explicitly open the cci namespace around the cci_value_converter specialization in ex16_user_datatype.h.

Hope that helps and thanks again,
  Philipp

Hello @Philipp A Hartmann,

Following is my testing development environment:

• Platform: Cygwin 64-Bit
• GCC Version: 6.4.0-5

And I have attached the verbose logs for build.

I tried your suggestions for wrapping the specialization of the cci_value_converter class with the CCI namespace in the ex16_User_Defined_Data_Type and it seems to fix the issue.

Also for the ex07_Parameter_Information example the following patch fixes the issue currently on Cygwin 64-bit.

You can also have a look into the verify logs after introducing these fixes.

I will also try to build and test on other environments and provide other feedback for the CCI release.

Update: Only for the ex16_User_Defined_Data_Type I need to make changes on Linux 64-Bit with g++(5.4.0 C++11 enabled).
