Hi,<br>
<br>
i again bitten by inability to access global symbols of VM module at run time..<br>
while on unixes, it is fairly easy to do:<br>
<br>
dlsym('foo', RTLD_DEFAULT);<br></blockquote><div> </div><div>Only because the linux VM is linked with -export-dynamic</div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
on windows, compiler/linker does not exposing any symbols :(<br></blockquote><div><br></div><div>But it can be asked to.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

so what i doing now is adding shitty primitives which just return<br>
pointers to variables....<br>
this smells bad..<br>
i wonder , is this impossible in principle, or it is just a<br>
win-specific default linker/compiler setting which<br>
different from unix one?<br></blockquote><div><br></div><div>I think I'm right in thinking it's the latter. If you're using the mingw cygwin compiler then, depending on version, you either use --export-dynamic or --export-all-symbols.
