remark #342-D: value copied to temporary, reference to temporary used

Terje Nilsen

Other Parts Discussed in Thread: OMAP3530

Using the c6000 tools for Linux, and writing software using the dsplink for OMAP3530 (all in Fedora Linux), I tend to get this "remark":

"remark #342-D: value copied to temporary, reference to temporary used"

It's OK, but fustrating as the printout gets confusing. I can avoid it by makeing all parameters a variable, but that makes no sense...

How can I make the compiler to not print thes messages ???

Best regards

Terje,

Please take a look at the code generation tools tips & tricks presentation at http://processors.wiki.ti.com/index.php/CGT_Tips_%26_Tricks_for_Beginners

The section on "Diagnostics" discusses the value of these diagnostic remarks, and how to suppress them if desired.

This remark is trying to tell you that there is a reference that doesn't refer to what it appears to refer to, because a temporary object was needed. This means if you try to modify the reference, you aren't actually changing what appeared on the right-hand-side of the assignment (or passed in as a parameter to a function), you are really modifying the temporary object, which will be thrown away. Try changing the reference into a reference to a const object. If that doesn't work, could you post a cut-down test case?
