We recommend you use qcc instead of gcc. |

If you use exceptions, you must link with the -lang-c++ option to qcc. This option is the default for QCC. |
We recommend you use qcc or QCC instead of gcc to compile and link your programs.
For detailed documentation about gcc, see the GNU website at http://www.gnu.org/.
|
If you have trouble using the default debug format (-gdwarf), switch to -gdwarf-2 or -gstabs. |
