Hello, can somebody help me compiling mcpov ? I put the mcpov's 
"0.0.5/sources" files contained in the folder to the "megapov/sources" 
folder but I have error while compiling, like...
parse.cpp:(.text+0x17a9c): undefined reference to `pov::sort_portals_MC'
parse.cpp:(.text+0x17aa8): undefined reference to 
`pov::check_portal_overlap_MC'
collect2: ld a retourné 1 code d'état d'exécution
make[2]: *** [megapov] Erreur 1
make[2]: quittant le répertoire « /home/seb/Bureau/megapov-1.2.1/unix »
make[1]: *** [all-recursive] Erreur 1
make[1]: quittant le répertoire « /home/seb/Bureau/megapov-1.2.1 »
make: *** [all] Erreur 2
etc...
How can I dow ?
Thank for helping me :s

This looks like some modules were either not re-compiled after applying the
source code changes, or they were not linked in (and maybe not even compiled at
all).

IIRC MCPov not only replaces files from MegaPOV, but also adds one or two; for
the .cpp files among those, you need to add the respective modules to the
makefile so they are compiled and linked properly.

Ok, but I have still the same errors... I've modified Makefile.am and 
Makefile.in located in "megapov/sources" isn't enough ?

	You need to reconfigure again.
	(Makefile.am is a template to generate Makefile.in through automake.)

I did manage to compile MCPov on Linux Debian "Etch" - but without running into
the problem you reported, so I'm probably not much help on this issue ;)

1. Download megapov 1.2.1 sources for Unix and save to any folder; unpack the archive:

wget 'http://megapov.inetart.net/packages/unix/megapov-1.2.1.tar.bz2'
tar xvjf megapov-1.2.1.tar.bz2

2. Download the following patch and save to the parent directory of megapov-1.2.1/

wget 'http://pov4grasp.free.fr/download/megapov-1.2.1-mcpov-0.0.5.patch.bz2'
bunzip2 megapov-1.2.1-mcpov-0.0.5.patch.bz2

(NOTE: the patch is based on the MC-POV 0.0.5 sources by Fidos available at:
http://pagesperso-orange.fr/fidos/MCPov/MCPov.html)

3. Patch the megapov sources -- no error/warning should be displayed; build megapov as
usual:

patch -p0 < megapov-1.2.1-mcpov-0.0.5.patch
cd megapov-1.2.1
./configure COMPILED_BY=you && make

	HTH,
	- NC

Basically all I did was...

(1) Unpack the MegaPOV 1.2.1 source code to somewhere
(2) Make sure I could compile original MegaPOV from that source
(3) Copy the MCPov source files (overwriting some of the MegaPOV source files)
(4) Add the new modules to the makefile
(5) Hack a few files to make sure MCPov would in *some* way identify itself as
such when run, so I'd be able to tell it apart from MegaPOV
(6) Compile, test and run

I'll try to elaborate more on steps (2) and (4) later, but I may need to retrace
(no pun intended) my own steps.

BTW, I think I didn't really install it, so I wouldn't risk messing up my
MegaPOV installation (official Linux AMD 64-bit binary from MegaPOV homepage).
Instead, the MCPov binary is just sitting somewhere in my home directory tree,
using MegaPOV's resources (include files and such) if I'm not mistaken.
