Re: perl DynaLoader.a exports dlclose and dlsym.

Dumb question: is there a drop-in patched version for dl_dyld.xs available somewhere?

... I'm not quite sure if I understand all the changes it's making when I look at the existing dl_dyld.xs. (I'm a newbie, sorry.) Thanks!

I am similarly unsure of exactly what you want to do :)

However, I'll make some assumptions and propose this solution:
1) Make a copy of /System/Library/Perl/darwin/auto/DynaLoader/DynaLoader.a somewhere.
2) Edit your makefiles so that they link against this copy.
3) make a file (call it something like rmsym.txt) with two lines. "_dlclose" on one and "_dlsym" on the other.
4) run nmedit -R rmsym.txt /path/to/your/special/DynaLoader.a
5) make

You may have to run ranlib once or twice in there on your DynaLoader.a copy.

(of course, if you are just doing this for yourself, you could run nmedit on the system DynaLoader.a, but I suggest you don't)

Hope this helps,
Peter
