Passing list of objects to GNU ld...

Passing list of objects to GNU ld...

[Berend Ozceri]

This is somewhat of a generic GCC question rather than a cygwin32 one, but I 
couldn't find anything in the man pages and info docs, so I figured I'd take a 
shot anyway...

Is there any way to get GNU ld to read the list of object files to be linked 
from a text file containing the names of the object files, one per line?

Thanks,

Berend

Not as such.  However, writing a file foo.t which contains lines like
    INPUT(foo.o)
    INPUT(bar.o)
and then linking against foo.t ought to work.  In general, if the
linker can not recognize an input file as an object file or archive,
it will attempt to read it as a linker script.

I couldn't have said it any better. Thank you Eric.

And thanks to everyone that suggested solutions. The most promising one seems 
to be that of generating a linker script that specifies the input files, but I 
haven't gotten around to trying it out.

In the meantime, I share Eric's belief that this would be a very desirable 
feature for the GNU linker.

No, the same problem doesn't exist.  You can append one file at a time
to the library.  One could create the library with a script file one
file at a time.

The same problem exists in the course of creating the library. If you have
lots of object files needed to link together for a program, then you may also
have lots of object files to place in the library.

I for one would like a feature of being able to list the object files in a
text file. On a daily basis I use this feature in commercial tool-chains.

How about:
 
 gcc `cat file`
