Porting another tcl/tk tool to NetBSD 1.0/i386, I found what seems
to be problem with PSIX compilance. Could somebody tell me where
exactly is the problem?
cc -c tkcanvas/tkCanvArc.c -o tkcanvas/tkCanvArc.o -O3 -I/usr/local/test/tcl-tk/tk3.6 -I/usr/local/test/tcl-tk/tcl7.3 -I/usr/local/install/tcl-tk/include -I/usr/X11R6/include -I/usr/local/install/pbmplus/include -I. -DPicassoLib=\"/usr/local/install/tcl-tk/picasso3.8/lib/tcl\" -DHAS_INRIM=0
In file included from /usr/local/test/tcl-tk/tk3.6/tkConfig.h:73, from tkcanvas/tkCanvArc.c:29:
/usr/local/test/tcl-tk/tcl7.3/compat/unistd.h:57: conflicting types for `lseek'
/usr/include/sys/types.h:84: previous declaration of `lseek
So, I looked tcl7.3/compat/unistd.h, and it says:
* Strict POSIX stuff goes here. Extensions go down below, in the
* ifndef _POSIX_SOURCE section.
extern long lseek _ANSI_ARGS_((int fd, long offset, int whence));
typedef quad_t off_t; /* file offset */
* This belongs in unistd.h, but is placed here to ensure that programs
* casting the second parameter of lseek to off_t will get the correct
* version of lseek.
off_t lseek __P((int, off_t, int));
So, what is wrong? Has this something to do with ``our'' bigger
off_t. Isn't this defined by POSIX? (I saw some days ago a discossion about
the type for off_t, but since I'm not a POSIX nor ANSI C guru, I didn't paid
a lot of attention... Sorry.
