4.6.3.3 Ext Option
The -mext=extension option controls the language
extension used during compilation. The allowed extensions are shown in the following
Table.
| Extension | C Language Description |
|---|---|
xc8 |
The native XC8 extensions (default). |
cci |
A common C interface acceptable by all MPLAB XC compilers. |
Enabling the cci extension requests the compiler to check
all source code and compiler options for compliance with the Common C Interface (CCI). Code
that complies with this interface can be more easily ported across all MPLAB XC compilers.
Code or options that do not conform to the CCI will be flagged by compiler warnings.
