Comment:
Precisely.
Anyway, here's the start of a Portfile.
I patched the Configure script to remove incorrect warnings and errors and
to look in `${prefix}` first so that our newer version of `bison` gets
used. Actually I think `bison` is also used at runtime.
During configuration, it tries to use `nm` to figure out what's in the C
library. It uses `printf` as its litmus test, and `printf` doesn't seem to
be in OS X's C library—or `nm` isn't the right way to make that
determination. If we can fix this it might help it find some other
functions.
The configuration asks some questions I didn't know the answers to, like
in which ways the compiler supports the `void` type or how many bits of
randomness the `random()` function produces. (The
[https://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man3/random.3.html
random() manpage] says all bits are random, but it returns a `long`;
doesn't the size of a `long` vary based on the build architecture?) I left
those answers at the defaults.
After configuration, it runs `make depend`, which generates a lot of
warnings and one error, I believe because it uses `cpp` which doesn't
understand some things in the system headers. Using `$CC -E` wouldn't
encounter those errors but is not an option because rayshade needs to feed
things to the C preprocessor via stdin and it seems that only `cpp`
understands that.
Then the build fails with various errors like:
{{{
hf.c:470:1: error: static declaration of 'CreateHfTriangle' follows non-
static declaration
}}}
{{{
hf.c:670:1: error: static declaration of 'GetQueuedTri' follows non-static
declaration
}}}
{{{
extended.c:58:1: error: static declaration of 'ExtendedIntens' follows
non-static declaration
}}}
{{{
fog.c:31:2: error: function declared in block scope cannot have 'static'
storage class
}}}
{{{
texture.c:165:3: error: non-void function 'TextToUV' should return a value
[-Wreturn-type]
}}}
And then finally:
{{{
/usr/include/strings.h:76:7: error: expected parameter declarator
}}}
{{{
/usr/include/strings.h:76:7: error: expected ')'
}}}
