Dear All:

I have some trouble when I configure POVRAY-3.5 on Redhad 7.3

As I type make, some error messages coming up as following:

.....
In file included from bbox.cpp:47:
optout.h:76: syntax error before `extern'
.....

I had change line 49 in file "optout.h" like this:

#define DISTRIBUTION_MESSAGE_1 "This is an unofficial version compiled by:"
Jong
#define DISTRIBUTION_MESSAGE_2 "FILL IN NAME HERE...."
#define DISTRIBUTION_MESSAGE_3 "The POV-Ray Team(tm) is not responsible for
supporting this version."

Is there any error in my configuration?
How should I do to solve the problem?
Thanks for the Help!

Jong

Your syntax error is here :

#define DISTRIBUTION_MESSAGE_1 "This is an unofficial version compiled by:"
Jong   <=====

it should be :
#define DISTRIBUTION_MESSAGE_1 "This is an unofficial version compiled 
by: Jong"

Thanks a lot! I pass that problem.
But now new troble coming up.
The error message say that:

.....
jpeg_pov.cpp:142:21: jpeglib.h: No such file or directory
make[1]: *** [jpeg_pov.o] Error 1
.....

It looks like that I don't have jpeglib.h in my OS.
Is it possible to ignore this error message?
Where can I find jpeglib.h to make the install pass?

you'll need to install the jpeg, png and tiff libs with developpement 
(frequently named "-devel") packages otherwise you won't be able to 
compile/link povray. All these may be available on your distrib's CDs.
As config files are cached by ./configure, you may need to completly 
delete the directory and re-extract the archive.

	Given what you did above, I'd suggest you do not try compiling povray,
but rather use the official Linux binary that should work on your RedHat distro.

	No, the correct answer is to fill in DISTRIBUTION_MESSAGE_2,
which is clearly stated as "FILL IN NAME HERE....".

	Fortunately this *very basic and documented* stuff will simply
vanish in 3.6...

On the contrary, he should compile Povray because he doesn't it will bee 
very very slow (optimized for pentium 1) whereas using an optimized 
version can improve performances by 50% !!! (to do this, you'll need to 
modify the Makefile => ask for it when you'll be ready)


There is no matter in compiling povray or something else even if you 
don't know how to do ! remember that you didn't know how to do at the 
begining, but you have learn it ! why wouldn't he be able to learn it too ?

	You mean that the official binary was compiled with no optimization
at all ?  (frankly I never tried it)

	May I ?
	Ok, go on, I'm ready  ;-)

	I simply made a very straightforward assumption: if someone makes
such an obvious mistake (as seen in the initial post), it is very likely
that he/she will have lots of trouble to compile povray at all, given
that the build system in the source of 3.50c is far from being complete
is known to have serious flaws (especially if you try to use it on anything
but a Linux box, which is actually the case here).
	Yet I admit that trying is indeed a good way to learn things, but
it'll most likely take quite some time.  This is not necessarily what Jong
is asking for (just a guess from his posts).

	But I should not make assumptions anyway, that's not a good idea
in general, and when programming in particular  :-)

	I should not only avoid making assumptions, but also read again
before posting.  So, add an "and" at the end of the first line, and
replace "actually" by "fortunately not"  :-)

There has been an early 3.5 official binary version compiled without 
optimization but the current official version is compiled with -O3.  And 
as you also observed some time ago the speed advantage with using more 
fancy (processor specific and possibly faulty) optimizations is 
marginal.  There is absolutely no need to compile POV-Ray from source 
just for the speed advantage (to actually save time this way, even if 
you have experience compiling programs yourself, you will have to render 
quite a lot of very slow scenes).
