World: r3wp

Just being able to compile the host source with a C++ compiler would 
be sufficient - having declarations still work, for instance. The 
rest could be handled with shim code, basicaly what most of the host 
code is anyways.

So far, that is - see recent blogs for details.

I try all to keep away from C++ these days. It just gives to much 
hassles when going from one compiler to the next.

Guys, there's a trouble with OS-X or so it seems. Any experienced 
OS-X coder to help? Message from Carl on R3 Chat:


I must set OS X on the back burner... I've wasted far too much time 
on it.

There are three choices on it:
1. find a tool that does what 
I need
2. make a tool that does what I need
3. join all the sources 
into one large .c compile

Note that gcc -fvisibility=hidden does 
not work, nor does __private_extern__ wor
k either.

I've got to 
get on with other projects now. So, if you happen to find the soluti
on, 
let me know. (PS, yes, using GCC > 4.0.)

Some explanation:


Back to OS X, the problem is that they're not really libs, they're 
.a's. This ev
en appears to be the case when -dynamic-lib is used.

I 
should mention that I've had -dynamic-lib built OS X libr3 and host 
working fo
r several days. But, the libr3 isn't in the form I want, 
because it's not intern
ally linked and resolved. Examining it with 
nm it looks like just a concat of .o
 files.

Specifically, I want 
all internal symbols resolved, and I only want to export th
e library 
interface.

If OS X only builds libs (dynamic or otherwise) as concatenated 
.o files, that's
 a serious breach of coding ethics! There are two 
reasons:

1. it means I can link against the internal interfaces 
- a serious short circuit
 in code encapsulation rules.

2. it means 
I can discover the entire internal structure of any product... say 
I
 want to peek inside Photoshop to see how it does something.

If 
I nm a lib that's been properly prepared, I should only see its API, 
nothing
else. So far, this has not been possible on OS X.

I suppose 
I could easily confirm this by nm'ing some of the various apps I 
have
on OS X and checking if I can see their internals. Let's hope 
not.

Wow, that explains why Apple has to sue developers for using undocumented 
APIs instead of just not exporting them.

wow

Well, I think I found the solution - it looks like Carl's assesmenmt 
of dylibs was wrong. Solutions posted in reply to him in chat.

I've been under that impression myself... but haven't found an exact 
solution.
