I am trying to compile software which requires unix.lib, but cannot find
unix.lib anywhere. Does anyone here know where I can find it?
Thanks,
Karen

Is this porting from QNX4? Have you tried linking without specifying
-lunix at all? You might find that most of the functions that were
in unix.lib are actually in our standard C library.
If not, on what functions does the link fail?

Actually, this is porting to QNX4, and the code is dying on a line reading
"bzero((void*)&start_tv, sizeof(start_tv)); bzero is undefined, and I’ve a
feeling it is supposed to belong to unix.lib. I may be wrong though. Any
ideas?

Hello,
If you’ve installed the QNX4 compiler package correctly you should have
a collection of unix*.lib also. The routine you’re referring to can be
found in the unix libs. With wlib you can check this:
/usr/watcom/10.6/usr/lib $ wlib unix3r.lib | grep bzero

brk_…brk bzero_…bzero
bzero Offset=00017000H
bzero_
However, there isn’t a specific “unix.lib” file. It depends on how
you’ve compiled your modules: 16 bit? 32 bit? register calling? stack
calling? (and in case of 16 bit) small/compact/medium/large model?
When you specify “-lunix”, the linker knows from your object model which
unix*.lib to select. Make sure the library search path is also correct.
(Perhaps by specifying this with the “-L” option)
One “gotcha” to look out for is mixed model linking. For instance if one
module is compiled with register calling (-3r), and the other with stack
calling (-3s), and you try to link them together, the linker will still
flag errors even though the routines are present. (IIRC, this even
happens when mixing “-5r” with “-3r” modules.)
good luck,
rick

bzero and friends were originally for sockets and friends so sometimes
they appear in socket libraries. The standard porting workaround is to
define a bzero macro like
#define bzero(b,len) memset(b, 0, (size_t)(len))
or
#define bzero(b,len) memset(b, 0, len)

Well, I should note than even when I try to use a simple hello world program
with the -lunix option, I get this error message:
cc warning: cc: cannot find library ‘unix’
the bzero substitution worked, but now I’m hitting the same problem on
different function names. Any suggestions?
Thanks,
Karen

The -lunix was a QNX4-ism that doesn’t exist on QNX6 so don’t bother
trying to link against it. We already support the masking of bzero
over to memset() in <strings.h>. What other issues are you hitting?

Can you post the entire command line that you pass to cc?
If you cd to /usr/lib, and do an “ls unix*” what do you see?
Do you set or modify the environment variable LIBQNX before invoking
cc?
