HEW error and warning messages?

Is there a list of the HEW error and warning messages anywhere? Specifically linker warnings, but C compiler messages will also be useful. I've looked in the online help, and the PDF HEW documentation, and I can't find any such list.

My immediate problem is the OptLinker warning message 'L1100 (W) Cannot find "C" specified in option "start"'. I have sent code which I have compiled correctly with HEW to a client; he gets that message when he attempts to compile. We're using the same source and project files. And I have not been able to duplicate that message here. I can't advise him where to look, because I don't know where 'option "start"' is specified, or why "C" is specified.

The only information I've been able to find here is on a forum message http://www.renesasrulz.com/message/2646 which suggests that the warning can be ignored. I'd like to have something more solid to go on before telling my client that he can ignore that message...especially when I don't get that message.

Re: HEW error and warning messages?

C is the area of memory allocated to constants. If you have none, then it is empty and the compiler warns you.

Make it go away by declaring one constant value somewhere in the C code.

(This is explained in the compiler/linker manual. Look for "Manual Navigator" in the Renesas folder in your Start menu.

Or you download the manual from our homepage (follow the documentation link on the compiler page):

Re: HEW error and warning messages?

Thank you! Because I'm using the H8S, I had downloaded the H8 compiler manual, which doesn't have that information. I didn't think to download the SH compiler manual, which does:

L1100 (W) Cannot find "name" specified in option "option"
The symbol name or section name specified in option cannot be found. The name specification is
ignored.

Now I just need to find where that symbol/section is specified.

Re: HEW error and warning messages?

The H8 manual has a similar list of error and warning messages:

For compiler V7

http://documentation.renesas.com/eng/products/tool/rej10j2039_r0c40008xsw07rum.pdf

The manual for V6 is on your computer and easiest to find using the Manual Navigator as Calvin mentioned earlier.

Re: HEW error and warning messages?

Thanks for that link. The compiler manual I downloaded is http://documentation.renesas.com/eng/products/tool/apn/rej05b0464_h8s.pdf dated Sep. 12, 2005.

This was offered as an "application note" for the HEW, found at http://america.renesas.com/products/tools/ide/ide_hew/Application_Notes.jsp

It duplicates the information found in the HEW's on-line help.

I've downloaded the correct manual now.
