Do you have any idea how to tell gcc to read in additional options from a file? Some stuff on the web indicates it should be doable by saying @file or -@file, but gcc (I've tried both 4.1 and 3.4) just doesn't recognize it.

The closest solution I've come up with is `cat file`, but this is... suboptimal.

[Asher]

Why not just use a makefile or cat?

I loathe gcc and I'm no expert in it, but the following should work:

gcc $(cat yourfile)

gcc `cat yourfile`

And of course it's sub-optimal. The word essentially defines gcc.

I am using a makefile.

The use case is I have a configuration tool that generates a file compiler.opt based on my build target (a variety of TI ARM processors), and I want to have a make rule a la:

progname.out : progname.obj compiler.opt
gcc -@compiler.opt ...

I'm sort of pissed you didn't ask me or JM this. Not that I knew, but still.

[Kuciwalker]

That's possibly one of the most ridiculous things I've ever seen you say.

I'm pretty sure physicists are the worst programmers on Earth.

I have seen worse programming on the net.

I admit some physicists are poor programmers... despite how bad I am (and I am better than last year, but still not great), I am better than average.

Thank you for providing the workaround I'VE ALREADY STATED I'D FOUND.

BC is a problem child.

But have you tried data compression?

[BlackCat]

yeah, he could try to zip it

I've seen some references to a @file parameter for gcc, but if it doesn't work for you, it doesn't work.

The beauty of Unix programming is if it works on one system, it won't work on another.
