Very Computer

Hello,

I'm experiencing a problem when linking a third party library
into my code. Does anyone know what the following linker error
message means?

/usr/bin/ld: Reference to <var> in file <filename> needs 3-instruction
sequence - Use +k to recompile
/usr/bin/ld: Data address is out of range for short load or store
   Reference from: <filename>
...
... <repeats>
...
/usr/bin/ld: Invalid fixups exist

Where <var> is some variable (eg. errno) and <filename> can be a system
file (e.g. /usr/lib/crt0.o) or one of our own.

If anyone has seen this linker error, I would greatly appreciate any
suggestions
they might have.

Thanks in advance,

Ciaran.

See the compiler man page for +k.

The message means you have more than ~2K or so globals.  You must recompile
with +k.  You may be able to compile only some of your objects or you
may have to do all of them.

I'm not sure if ordering the ones you recompile with +k first or last will
do the most good.

I have not seen this with HPs linker, but I have seen the equivalent with
other systems. Basically the linker is not able to do the linking requested
by the compiler. There are several possible causes:

Compiler error : compiler generating wrong link information or to restrictive
    link information.
Compiler and linker incompatible: Is the third party library built for a later
    version of the OS and linker or specifically for a different processor
    varient? Possibly mixing specific compilation/linking options might cause
    problems. I can't think of any off the top of my head for HP.
Object file mangled: Try reinstalling.
Linker error: linker has got it self in a mess.
Exceptional size of executables or object modules: can sometimes cause problems
    if they exceed the size of the addressing format used by the compiler.
    I doubt if this is the case here.

 Are you using ISO8859-1? Do you see ? as copyright, as division and ? as 1/2?

I looked up the +k option in our HP documentation. The problem is, we're
compiling
with gcc (2.6.3) not cc. gcc doesn't support the +k option. Looking at
the gcc
man page, I can't seem to find an equivalent option.

Thanks again for your help.

Ciaran.

Newer versions of gcc (I believe starting from 2.7.1) no longer need this.

[that is: at least I no longer needed to supply +k (cc) or -mlong-calls (gcc),
but you mileage may vary....]

gcc-2.7.2 has been out for almost a year.

Try gcc 2.7.2 (with gas), maybe obtain a newer /bin/ld.
