Programming

I want to compile all files in my directory i wrote
find *.c | gcc -o * *.c
but it dosent work Help pliz

Well, if every is a main:

Code:

#!/usr/bin/ksh
 
for f in *.c
do
 gcc -o ${f%.c} $f
done

If they are all subroutines but one with a main, use this:

Code:

gcc -c *.c
ar all.a *.o
gcc -o my_name all.a

Not sure at all about the ar command line being correct, just a hint. Subroutine order in a *.a is not important like on a cc/link, so linking from all.a always works. Since it is an ar from scratch, you want the anti-quadratic option!

Does gcc even take piped input? I don't think I've ever seen any compiler used that way.

What are you trying to accomplish? Compile a bunch of C files into one executable? There's an even simpler way than the examples DGPickett provided:

Code:

gcc *.c -o yourBinaryFileName

The "*.c" argument is expanded by your shell to every file in your current directory that ends in ".c", no matter what it begins with (as long as it doesn't start with a "." character, anyway), and the "-o" argument tells gcc that the next argument is the name of the file it's to use to write its output to.

What about using Makefile(s) ?

Make is great, except nobody seems to keep it clean enough to work right, and so has to purge and build from scratch all the time, or has n different versions of the same source file in production. I noticed in Ant they said don't bother, just make it all again. Of course, it is nice if you can do that quickly, like in parallel, but with clean logging and error handling, so you can tell if it ran, and if not, why not, and where.

PS: If the files are subroutines but one or no mains, and you compile them all at once, some compilers can optimize between files, like inlining.

That might be a good down-to-earth comment for many SW-development teams... But with such an answer, you won't get any vacancy in my team *LOL*

I have made my living cleaning up make files, an endless task, even with the cc support and even with dynamic libs. I used to run all prod through a what script to see the multiple versions installed. However, many make a good living chasing this butterfly!
