Bug #: 54631
Summary: vxworks.c fails to compile
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: r...@verizon.net
I just pulled in the latest changes, and vxworks.c no longer compiles. The
error is at bottom.
I think this has to do with the upgrade to C++. The code in question does
this:
elt = VEC_quick_push(constructor_elt, v, NULL);
The problem with this is that NULL is not convertible to const constructor_elt
&. I think that with the old C API this would just construct a new object, but
that doesn't work anymore.
Changing the code to construct the object first and then add it to the vector
should work, but I don't know enough about the code to be sure.
As a question, should these files be changed to use the C++ API? Or should
they stick with pretending that they're straight C?
Thanks!
