Hello,
I am running under Suse Linux and am putting together some code written
in C. I am not clear on how to create makefiles and was wondering if
there were any "makefile tools" out there. If so, what are the best
ones?
If you don't want to get into autoconf etc, it's trivial to generate your
own simple makefiles by writing a program in elementary ISO C. Here's a
really, really simple one which you can hack to your heart's content.
#include <stdio.h>
void genflags(void)
{
puts("CC=gcc");
puts("CFLAGS=-W -Wall -ansi -pedantic -O2");
puts("DFLAGS=-g -pg");
}
void makeprg(int argc, char **argv)
{
int i = 0;
printf("%s: %s.o", argv[1], argv[1]);
for(i = 2; i < argc; i++)
{
printf(" %s.o", argv
);
}
printf("\n\t$(CC) $(CFLAGS) $(DFLAGS) -o %s %s.o", argv[1], argv[1]);
for(i = 2; i < argc; i++)
{
printf(" %s.o", argv);
}
putchar('\n');
}
void makeobjs(int argc, char **argv)
{
int i = 0;
for(i = 1; i < argc; i++)
{
printf("%s.o: %s.c\n", argv, argv);
printf("\t$(CC) $(CFLAGS) $(DFLAGS) -c -o %s.o %s.c\n", argv,
argv);
}
putchar('\n');
}
void makeclean(int argc, char **argv)
{
int i = 0;
printf("clean:\n");
for(i = 1; i < argc; i++)
{
printf("\trm %s.o\n", argv);
}
printf("\trm %s\n", argv[1]);
putchar('\n');
}
void makeinstall(int argc, char **argv)
{
printf("install:\n");
printf("\tcp %s /usr/local/bin\n", argv[1]);
putchar('\n');
}
int main(int argc, char **argv)
{
if(argc > 1)
{
genflags();
makeprg(argc, argv);
makeobjs(argc, argv);
makeclean(argc, argv);
makeinstall(argc, argv);
}
else
{
fputs("Usage: makegen progname [sourcename*]\n", stderr);
}
return 0;
}
