VxWorks Options (Using the GNU Compiler Collection (GCC))

#### 3.20.55 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__`.

`-msmp` ¶

  Select SMP runtimes for linking. Not available on architectures other than PowerPC, nor on VxWorks version 7 or later, in which the selection is part of the VxWorks build configuration and the library paths are the same for either choice.

`-mvthreads` ¶

  Link against the VxWorks AE vThread runtime environment.

`-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 Options for Linking); `-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.
