problem with linking

[EM Suijker]

Dear Mr./Madam,

Can you help me with the following problem. When I use the command: "
g++ -v -shared ....", I see that collect2 also sets the option "-z
text". I would like to set this option to "-z textoff" as is the default
for dynamic shared libraries with ld. Can you tell me how to do this? I
cannot find the solution in the manual pages. Thank you in advance.

With kind regards,
Erwin Suijker

Note:
I am using Solaris 7 on a Sparc machine.

IIRC, there is an option to pass to GCC to specify options to be passed to 
the linker. You ca use those, to override "-z text" w/ "-z textoff".
Have a llok at the GCC manual, I don't remember the option.

BTW, I don't know if what I'm saying is sane to do or not...

almost. '-Wl,-z textoff'
I believe the quotes are necessary.

It's quite sane.

Re: problem with linking

[EM Suijker]

Thank you for the replies. 

The option -Wl,-ztextoff results in a message that not both options
-ztext and -ztextoff can be used. So this does not override the option.
But I looked in the manual again and found a chapter about spec files.
It is possible to write your own spec file. For me it was enough to look
into the spec file. You have to use the flag -mimpuretext so -ztext will
not be passed to the linker. If you leave out this flag the spec file
automatically passes this the option -ztext to the linker.

Best regards,
Erwin Suijker

I think you mean  -Wl,-z,textoff

I have no idea if this will help Mr. Suijker, either.

Hi,

youd have to type:

gcc -L [libpath] -lsql .........

instead.

problem with linking

[Preeti Gopalan]

Hi 
This is a bit basic. 
I am trying to use a Math.h function

So I compile my program  as gcc fname.c -lm -time 

Is the -ltime part right ? 
If not , How do I do it? 
It says undefined reference to function

Thanks a lot

Why are you trying to add -ltime?  It shouldn't be necessary.

> It says undefined reference to function

Which function?
