Hello,

I am completely new to the CCS, please accept my apologies for possibly simple questions.

I have to profile a codec (in .cpp) in terms of latency for a CPU. I am not sure if I am in the correct path, but I have created a new CCS project, and created the folders and files corresponding to the codec. I have chosen C6000 family, Generic C64x+ Device, and rts64plus.lib as the general configurations. But I am completely uncertain about all of  the settings.

I have also created a .ccxml file in which the connection is Texas Instruments Simulator with C64x+ CPU Cycle Accurate Simulator, Little Endian as the device.

When I try to build the application, I encounter an error:

fatal error #5: could not open source file "sys/time.h"

Do I have to choose another compiler? What are the best settings to keep the codec running?

Please let me know if I have to provide more information.

Thank you in advance.

Do you have a line in your code something like #include "sys/time.h"?  If so you will want to edit the include paths for your project.  Basically the compiler needs to know where to look for this file.  In your case it is already if the file is in C:\stuff\stuff\stuff\sys\time.h then you would want to setup the include path as C:\stuff\stuff\stuff as you already have \sys in your #include statement.

You can edit your include paths by right clicking on your project.  Select Properties.  Under CCS Build you should see C6000 compiler.  Expand that and look for the Include Options group.  Click on it and then on the right hand side you will be able to setup the include paths

Regards,

Hello John,

I really appreciate your help.
Actually I have found two versions of "time.h", one in "C:/ti/ccsv5/tools/compiler/c6000/include", and the other one in

"C:/cygwin/usr/include".

I got the impression that the required "time.h" file, is the second one (located in "C:/cygwin/usr/include"),

but I am not certain though.

So, I tried these settings:
1. I added "C:/cygwin/usr/include", in the Include Options for C6000 compiler, just as you told me.
But I encountered some compilation errors, such as:

"C:/cygwin/usr/include/sys/_types.h", line 36: error #78-D: this declaration has no storage class 
or type specifier
"C:/cygwin/usr/include/sys/_types.h", line 36: error #66: expected a ";"
"C:/cygwin/usr/include/sys/types.h", line 116: error #268: "time_t" is ambiguous
"C:/cygwin/usr/include/sys/time.h", line 18: error #268: "time_t" is ambiguous
"C:/cygwin/usr/include/sys/time.h", line 38: error #268: "timeval" is ambiguous
"C:/cygwin/usr/include/sys/time.h", line 39: error #268: "timeval" is ambiguous
"C:/cygwin/usr/include/sys/time.h", line 74: error #268: "timeval" is ambiguous
"C:/cygwin/usr/include/sys/time.h", line 75: error #268: "timeval" is ambiguous
"C:/cygwin/usr/include/sys/time.h", line 76: error #268: "timeval" is ambiguous
"..\XFramework\XUtilities\..\..\Project\..\Tools\HRTimer.h", line 53: error #268: "timeval"
is ambiguous
"..\XFramework\XUtilities\..\..\Project\..\Tools\HRTimer.h", line 54: error #268: "timeval"
is ambiguous

2. Then I removed "C:/cygwin/usr/include" from the Include Options, and decided to make a new folder named "sys"

in this path: "C:/ti/ccsv5/tools/compiler/c6000/include", and copied "time.h" from "C:/cygwin/usr/include" to this

new folder.

This is the error in this case:
"C:/ti/ccsv5/tools/compiler/c6000/include/sys/time.h", line 8: fatal error #5: could not open source file "_ansi.h"
And I can't find this "_ansi.h" file anywhere!

I would be so grateful if you could guide me to resolve these errors.

Best regards

Are you including cygwin in your application?  If not then the time.h file you need is the one in C:/ti/ccsv5/tools/compiler/c6000/include

Can you show the full error code that says "fatal error #5: could not open source file "sys/time.h"  It should have a source file associated with it.

Since I'm just using this codec (it has been developed by other people), I am not sure whether I have to include 
cygwin or not.
