UNIX cc executable location
When I compile a .c
file using the cc
command, it creates an a.out
executable. I've noticed that it creates the a.out
file inside my current directory. Is there a way to make the a.out
file be created in the same directory as the .c
file wherever I happen to be开发者_开发技巧 on the system?
for example if my current path is ~/desktop
and I type in the command:
cc path/to/my/file/example.c
It creates the a.out
file in the ~/desktop
directory. I would like it to create the a.out
file in path/to/my/file/a.out
You will have to use the -o switch each time you call cc:
cc -o path/to/my/file/a.out path/to/my/file/example.c
or you can make a wrapper script like this:
mycc
#!/bin/bash
dirname=`dirname "$1"`
#enquoted both input and output filenames to make it work with files that include spaces in their names.
cmd="cc -o \"$dirname/a.out\" \"$1\""
eval $cmd
then you can invoke
./mycc path/to/my/file/example.c
and it will, in turn, call
cc -o "path/to/my/file/a.out" path/to/my/file/example.c
of course you can put mycc in $PATH so you can call it like:
mycc path/to/my/file/example.c
You can give the "-o" flag to define the output file. For example:
cc path/to/my/file/example.c -o path/to/my/file/a.out
Yes, with -o
.
cc path/to/my/file/example.c -o path/to/my/file/a.out
It may be not what you're looking for, but you can easily redirect the output of a compilation using the -o
siwtch like this:
cc -o /a/dir/output b/dir/input.c
I don't know, how to archieve, what you want (auto replacement), but I guess you can do it with some bash like this: (I'm poor in scripting, untested and may be wrong):
i = "a/path/to/a/file.c" cc -o ${i%.c} $i
This should compile a file specified in i into an output file in same dir, but with the .c-suffix removed.
