3.17.52 VxWorks Options

The options in this section are defined for all VxWorks targets. Options specific to the target hardware are listed with the other options for that target.

-mrtp
GCC can generate code for both VxWorks kernels and real time processes (RTPs). This option switches from the former to the latter. It also defines the preprocessor macro __RTP__.
-non-static
Link an RTP executable against shared libraries rather than static libraries. The options -static and -shared can also be used for RTPs (see Link Options); -static is the default.
-Bstatic
-Bdynamic
These options are passed down to the linker. They are defined for compatibility with Diab.
-Xbind-lazy
Enable lazy binding of function calls. This option is equivalent to -Wl,-z,now and is defined for compatibility with Diab.
-Xbind-now
Disable lazy binding of function calls. This option is the default and is defined for compatibility with Diab.
