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[i]);
}
printf("\n\t$(CC) $(CFLAGS) $(DFLAGS) -o %s %s.o", argv[1], argv[1]);
for(i = 2; i < argc; i++)
{
printf(" %s.o", argv[i]);
}
putchar('\n');
}
void makeobjs(int argc, char **argv)
{
int i = 0;
for(i = 1; i < argc; i++)
{
printf("%s.o: %s.c\n", argv[i], argv[i]);
printf("\t$(CC) $(CFLAGS) $(DFLAGS) -c -o %s.o %s.c\n", argv[i],
argv[i]);
}
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[i]);
}
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;
}
