Hello,

Since everyone started to do private compiles I thought I might give it a
try on Cygwin (unix enviroment under Windows). And I end up with the
following error:

g++ -DPREFIX=\"/usr/local\" -DPOV_LIB_DIR=\"/usr/local/share/povray-3.5\"
-DCOMPILER_VER=\".Linux.gcc\" -DSYSCONFDIR=\"/usr/local/etc\"     `if [
"Xgcc" = "Xgcc" ]; then echo "-Wno-multichar"; fi ` -I/usr/X11R6/include
-I/usr/X11R6/include/X11 -c unix.cpp
unix.cpp:101: libgen.h: No such file or directory
make: *** [unix.o] Error 1

And I don't seem to have libgen.h on my system at all, any clue where I
could find a copy of it?

TIA, Thomas

ps. Anyone tried AIX yet?

OK Solved that one... I found an answer here:

http://www.dgp.toronto.edu/~ravin/courses/csc428f01/tutorials/assignment2/faq.html

So that solves my basename problem. And the next one is:

g++ -DPREFIX=\"/usr/local\" -DPOV_LIB_DIR=\"/usr/local/share/povray-3.5\"
-DCOMPILER_VER=\".Linux.gcc\" -DSYSCONFDIR=\"/usr/local/etc\"     `if [
"Xgcc" = "Xgcc" ]; then echo "-Wno-multichar"; fi ` -I/usr/X11R6/include
-I/usr/X11R6/include/X11 -c unix.cpp
unix.cpp: In function `int subdir(const char *, char (*)[259], char
(*)[259])':
unix.cpp:970: implicit declaration of function `int dirname(...)'
unix.cpp:970: assignment to `char *' from `int' lacks a cast
make: *** [unix.o] Error 1

any clue? Where is dirname declared?

When I compiled under Mac OS X, I just commented the #include out and 
implemented my own basename() and dirname() functions. They haven't been 
tested, but here they are:

char * basename(char * path)
{
    int j = 0;
    int idx = 0;//current starting location of copy
    while(path[j])
    {
        if(path[j] == '/')
        {
            idx = 0;
        }
        else
        {
            path[idx] = path[j];
            idx++;
        }
        j++;
    }
    path[j] = '\0';
    return path;
}

char * dirname(char * path)
{
    int idx = -1;//index of last '/' in string
    for(int j = 0; path[j]; j++)
        if(path[j] == '/')
            idx = j;
    
    if(idx != -1)
        path[idx + 1] = '\0';
    
    return path;
}

Thanks Chris!

That did the trick. I had only one problem after that, one of the files is
compiled with the C compiler instead of the C++ compiler and not all the
path were inserted at the right places. Wich reminds me of a nother small
problem, the ./configure does not pick up the paths to the X-windows stuff
properly. I don't know whether this is a weird cygwin thing or that is
related to the script it self. Just copying the path into the make file did
the trick.

I haven't tried running it with a scene file yet, but compiling and linking
works fine and so does the normal output.

Tried that as well, had some problems with the I/O restrictions (just as
everyone else ;), but it runs fine, even with a X Windows display.
