The STLport bundled with the SunStudio11 generates alot of warnings. I beleive most compilers have a way to disable warnings from certain source files, like this:
Sun C
#pragma error_messages off
#include <header.h>
// ...
#pragma error_messages on
gcc
#pragma warning(push, 0)
#include <header.h>
// ...
#pragma warning(pop)
How do you do this in the SunStudio C++ compiler? (btw, the sunstudio C pragmas don't work in sunstudio C++)
回答1:
In SunStudio 12, the #pragma error_messages work as documented in the C users manual.
You can see the tags with the -errtags=yes option, and use it like this:
// Disable badargtypel2w:
// String literal converted to char* in formal argument
#pragma error_messages (off, badargtypel2w )
and then compile with CC (the C++ compiler).
回答2:
If you'd rather use a command line option than #pragmas, a simple answer is that you can use -erroff=%all on your compile line.
You can suppress specific warning messages with -erroff=%tag
You can print out the tags for the warning messages by adding -errtags to your compile line. You can then define a set of comma-separated values for -erroff that suppress just those tags.
See http://docs.oracle.com/cd/E19205-01/820-7599/bkapa/index.html for more info.
Note that Sun Studio 12 update 1 is now available, and I'm referencing the SS12u1 doc here.
回答3:
Can't help with turning the warnings off, but when I last looked at SunStudio, it shipped with two STLs - an older one for backward compatibility with earlier compiler versions and STLport. Might be worth checking if you're using STLport before trying to trying to turn off the warnings.

add -w to your $CC or whatever var you use.
