| |
| <p><a name="index-Solaris-2-options-2177"></a> |
| These ‘<samp><span class="samp">-m</span></samp>’ options are supported on Solaris 2: |
| |
| <dl> |
| <dt><code>-mimpure-text</code><dd><a name="index-mimpure_002dtext-2178"></a><samp><span class="option">-mimpure-text</span></samp>, used in addition to <samp><span class="option">-shared</span></samp>, tells |
| the compiler to not pass <samp><span class="option">-z text</span></samp> to the linker when linking a |
| shared object. Using this option, you can link position-dependent |
| code into a shared object. |
| |
| <p><samp><span class="option">-mimpure-text</span></samp> suppresses the “relocations remain against |
| allocatable but non-writable sections” linker error message. |
| However, the necessary relocations trigger copy-on-write, and the |
| shared object is not actually shared across processes. Instead of |
| using <samp><span class="option">-mimpure-text</span></samp>, you should compile all source code with |
| <samp><span class="option">-fpic</span></samp> or <samp><span class="option">-fPIC</span></samp>. |
| |
| </dl> |
| |
| <p>These switches are supported in addition to the above on Solaris 2: |
| |
| <dl> |
| <dt><code>-pthreads</code><dd><a name="index-pthreads-2179"></a>Add support for multithreading using the POSIX threads library. This |
| option sets flags for both the preprocessor and linker. This option does |
| not affect the thread safety of object code produced by the compiler or |
| that of libraries supplied with it. |
| |
| <br><dt><code>-pthread</code><dd><a name="index-pthread-2180"></a>This is a synonym for <samp><span class="option">-pthreads</span></samp>. |
| </dl> |
