Re: any file -- symbol in .o file
Take a look at file2c. You'll need to run the source through the compiler first, but that is easy to do with make. E.B.

Re: any file -- symbol in .o file
JM Date: Sun, 19 May 2002 21:41:05 -0700 JM From: Jonathan Mini JM Take a look at file2c. You'll need to run the source through JM the compiler first, but that is easy to do with make. H. Definitely produces the desired results for the simple case that I mentioned. In fact, more complex things (hash functions, tries, etc.) can be accomplished by writing a quick bin to perform the proper transform, then feeding that to file2c; a shell script can orchestrate everything. I guess I'll run with that for now. Off the top of my head, the only feature file2c can't provide is user-specified data alignment. (Unless, of course, someone corrects me and alerts me to a C preprocessor directive similar to assembly's .align.)

You probably also want to look at objcopy. You can skip the compile step
if you're prepared to use a bit of linker magic:
peter@overcee[10:28pm]/tmp-192 cat p.c
extern char __start_buf[]; /* magic */
extern char __stop_buf[]; /* more magic */
main()
{
printf(%.100s\n, __start_buf);
}
peter@overcee[10:28pm]/tmp-193 cc -c p.c
peter@overcee[10:28pm]/tmp-194 objcopy --add-section buf=/etc/termcap \
--set-section-flags buf=load,alloc p.o p2.o
peter@overcee[10:28pm]/tmp-195 cc -o p2 p2.o
peter@overcee[10:29pm]/tmp-196 ./p2
# Copyright (c) 1980, 1985, 1989, 1993
# The Regents of the University of California. All rights re
The trick is that __start_[sectionname] and __stop_[sectionname] are magic.
The other trick is that you have to set the flags to load,alloc or you will
be somewhat disappointed.
Bear in mind that the sections are verbatim, ie: not null terminated. You
would have to do address arithmetic on the delimiter symbols to get the
size.
