Boost.Dll Compile error with VxWorks, but not Linux?

Boost - Build mailing list

Hi Experts,

I’m able to run the Dll tests with <link>static on Linux,

>    cd status

>    ../b2 <link>static –limit-tests=”dll”

But when I’m cross compiling for VxWorks I get compile errors in the dependent filesystem library.

I can solve this by adding an explicit <link>shared to the test .. e.g.

 

From dll/build/Jamefile.v2

        [ run cpp_import_test.cpp   : : cpp_plugin : <target-os>vxworks:<link>shared ]

 

But I’m wondering why?

How did both conditions in filesystem get defined i.e :

 

From filesystem/build/Jamefile.v2

    : usage-requirements # pass these requirement to dependents (i.e. users)

      <link>shared:<define>BOOST_FILESYSTEM_DYN_LINK=1

      <link>static:<define>BOOST_FILESYSTEM_STATIC_LINK=1

 

Many Thanks,

 

Brian Kuhl

I suspect that you've managed to link to both static filesystem
and dynamic filesystem, but I'm unsure of the exact reason.
To verify this theory, run with -n and check the link command(s).
