=== Dynamic linking === |
|||
If you want to support dynamic linking with your toolchain, you need to... |
|||
* Pass the <tt>"--enable-shared"</tt> flag to the <tt>./configure</tt> scripts of both binutils and gcc |
|||
* Set <tt>LINK_SPEC</tt> in your "gcc/config/myos.h" so the gcc driver will pass the correct flags to the linker: |
|||
<source lang="C"> |
|||
#undef LINK_SPEC |
|||
#define LINK_SPEC "%{shared:-shared} %{static:-static} %{!shared: %{!static: %{rdynamic:-export-dynamic}}}" |
|||
</source> |
