I just downloaded v3.3beta015 and tried to compile it on a NeXT (a black one and a white one, same problems on both :-). The libtiff.a makes like a charm without problems, but tiffdump gives me a headache:
cc -o tiffdump -g -I../libtiff tiffdump.c
tiffdump.c:158: illegal function call, found `0'
tiffdump.c:239: illegal function call, found `off'
tiffdump.c:239: illegal expression, found `)'
tiffdump.c:243: illegal external declaration, found `if'
tiffdump.c:243: illegal external declaration, missing `;' after `*'
and so on and on.After some investigation I found that the type off_t is unknown. In complete ignorance I added the line
#define off_t int
at the beginning of the file and now it makes without errors. However, I don't know if this change of mine is reasonable at all...
off_t is the type of a file offset, usually long or unsigned long. If sizeof (int) == sizeof (long) on your system then it's ok.
The next problem is with fax2ps:
cc -O -ansi -I../../libtiff -c fax2ps.c
../../libtiff/tiffiop.h:42: undefined type, found `u_long'
../../libtiff/tiffiop.h:57: undefined type, found `u_long'
../../libtiff/tiffiop.h:92: undefined type, found `u_char'
../../libtiff/tiffiop.h:93: undefined type, found `u_char'
../../libtiff/tiffiop.h:94: undefined type, found `u_char'
../../libtiff/tiffiop.h:201: undefined type, found `u_short'
and so on and on.Here it helps to remove the -ansi from the compiler options, but then I have a more serious problem:
cc -O -I../../libtiff -c fax2ps.c
fax2ps.c: In function `printTIF':
fax2ps.c:425: structure has no member named `white'I checked into this: line 425:
fax.b.white = (photometric == PHOTOMETRIC_MINISBLACK);
and fax.b is of type Fax3BaseState which is defined in tif_fax3.h as
typedef struct {
short data; /* current i/o byte */
short bit; /* current i/o bit in byte */
u_long rowbytes; /* bytes in a decoded scanline */
u_long rowpixels; /* pixels in a scanline */
enum { /* decoding/encoding mode */
G3_1D, /* basic 1-d mode */
G3_2D /* optional 2-d mode */
} tag;
const u_char *bitmap; /* bit reversal table */
u_char *refline; /* reference line for 2d decoding */
} Fax3BaseState;which does not include any white member, in deed! Being bold, I tried adding such a white member, but this then leeds to a lot more trouble (many missing functions and so on), so I am stumped here.
Is there s.th. I am doing wrong or can anyone help??
The fax2ps code that "leaked out" in beta015 was old code. I'll include a working a version in the next beta that should come out next week.
