单龙芯3A3000-7A1000PMON研究学习-（10）撸起袖子干-pmoncfg Bonito 干了什么？（这是make cfg的部分）
1.前面留下了问题，第5条。
使用了pmoncfg命令，目录在 Targets/Bonito3a3000_7a/conf/中，执行命令pmoncfg Bonito
Bonito 是一个文件，但是里面只有一个包含语句：
include "Targets/Bonito3a3000_7a/conf/Bonito.3a3000_7a"
实际使用的还是 Targets/Bonito3a3000_7a/conf/Bonito.3a3000_7a这个文件，这个文件内容比较多，我先贴出来：

稍微看一下的话，可能意识到这是个功能配置文件，对于这个系统，你需要选择哪些功能，或者使用了哪些自带的部分等。
2.顾名思义，pmoncfg要根据这个文件中的一些选项，产生一些宏定义（用于控制代码的条件编译）。
要细看的话，还得仔细分析pmoncfg的源代码才行。这里必然会生成一些h文件或者其他的配置文件。
这里应该就是
a.创建软连接-----mksymlinks
static int
mksymlinks()
{
int ret;
char *p, buf[MAXPATHLEN];
const char *q;
sprintf(buf, "Targets/%s/include", machine);
p = sourcepath(buf);
(void)unlink("target"); //删除原来的链接
ret = symlink(p, "target"); //1.创建新的连接
if (ret)
(void)fprintf(stderr, "config: symlink(target -> %s): %s\n",
p, strerror(errno));
if (machinearch != NULL) {
sprintf(buf, "sys/arch/%s/include", machinearch);
p = sourcepath(buf);
q = "machine";
} else {
p = strdup("machine");
q = strdup("target");
}
(void)unlink(q); //删除原链接
ret = symlink(p, q); //2.创建新的链接
if (ret)
(void)fprintf(stderr, "config: symlink(%s -> %s): %s\n",
q, p, strerror(errno));
free(p);
return (ret);
}这里我注释了两个地方创建新的连接。
注释1的链接文件
注释2的链接文件，注意这个目录的位置
b.创建makefile----mkmakefile
int
mkmakefile()
{
register FILE *ifp, *ofp;
register int lineno;
register int (*fn) (FILE *);
register char *ifname;
char line[BUFSIZ], buf[200];
(void)sprintf(buf, "Targets/%s/conf/Makefile.%s", machine, machine);
ifname = sourcepath(buf);
if ((ifp = fopen(ifname, "r")) == NULL) { //1.输入文件
(void)fprintf(stderr, "config: cannot read %s: %s\n",
ifname, strerror(errno));
free(ifname);
return (1);
}
if ((ofp = fopen("Makefile", "w")) == NULL) { //2.输出文件
(void)fprintf(stderr, "config: cannot write Makefile: %s\n",
strerror(errno));
free(ifname);
return (1);
}
if (emitdefs(ofp) != 0)
goto wrerror;
lineno = 0;
while (fgets(line, sizeof(line), ifp) != NULL) { //3.从输入文件读1行，然后分析，然后继续循环读取
lineno++;
if (line[0] != '%') { //4.一行的第一个字符不是%，则出错，
if (fputs(line, ofp) < 0) //5.写入文件失败，结束
goto wrerror;
continue; //6.继续读取下一行
}
if (strcmp(line, "%OBJS\n") == 0) //7.这一行的内容是%OBJS
fn = emitobjs; //8.函数指针赋值
else if (strcmp(line, "%CFILES\n") == 0)
fn = emitcfiles;
else if (strcmp(line, "%SFILES\n") == 0)
fn = emitsfiles;
else if (strcmp(line, "%RULES\n") == 0)
fn = emitrules;
else if (strcmp(line, "%LOAD\n") == 0)
fn = emitload;
else {
xerror(ifname, lineno,
"unknown %% construct ignored: %s", line);
continue; //9.无法识别，下一行
}
if ((*fn)(ofp)) //10.调用刚刚赋值的函数，参数传入输出文件描述符
goto wrerror;
}
if (ferror(ifp)) { //11.检查退出循环的原因，读文件出错了么？
(void)fprintf(stderr,
"config: error reading %s (at line %d): %s\n",
ifname, lineno, strerror(errno));
goto bad;
/* (void)unlink("Makefile"); */
free(ifname);
return (1);
}
if (fclose(ofp)) { //12.关闭输出文件
ofp = NULL;
goto wrerror;
}
(void)fclose(ifp); //13.关闭输入文件
free(ifname);
return (0); //14.正常返回0
wrerror:
(void)fprintf(stderr, "config: error writing Makefile: %s\n",
strerror(errno));
bad:
if (ofp != NULL)
(void)fclose(ofp);
/* (void)unlink("Makefile"); */
free(ifname);
return (1);
}这里还有一些对应的函数要执行。
但是可以看出来，是生成了一个Makefile文件，看这个时间也是最新的，文件还不小。
内容非常多，我贴出一部分吧，前面这部分也是最重要的。

${NORMAL_C}这里涉及了一些目标。包括编译时的一些宏定义（第一行），应该说是非常重要的一个文件。
c.创建头文件----mkheaders
这一块似乎看不出啥。贴个代码吧，其实没啥意义
int
mkheaders()
{
register struct files *fi;
register struct nvlist *nv;
for (fi = allfiles; fi != NULL; fi = fi->fi_next) {
if (fi->fi_flags & FI_HIDDEN)
continue;
if (fi->fi_flags & (FI_NEEDSCOUNT | FI_NEEDSFLAG) &&
emitcnt(fi->fi_optf))
return (1);
}
for (nv = defoptions; nv != NULL; nv = nv->nv_next)
if (emitopt(nv))
return (1);
return (0);
}d.创建ioconf文件。 -----mkioconf
int
mkioconf()
{
register FILE *fp;
int v;
qsort(packed, npacked, sizeof *packed, cforder);
if ((fp = fopen("ioconf.c", "w")) == NULL) {
(void)fprintf(stderr, "config: cannot write ioconf.c: %s\n",
strerror(errno));
return (1);
}
v = emithdr(fp);
if (v != 0 || emitexterns(fp) || emitloc(fp) ||
emitlocnames(fp) || emitpv(fp) || emitcfdata(fp) ||
emitroots(fp) || emitpseudo(fp)) {
if (v >= 0)
(void)fprintf(stderr,
"config: error writing ioconf.c: %s\n",
strerror(errno));
(void)fclose(fp);
/* (void)unlink("ioconf.c"); */
return (1);
}
if (fputs("#endif /* NMAINBUS */\n", fp) < 0)
return (1);
(void)fclose(fp);
return (0);
}具体内容参考ioconf.c,这部分内容应该是比较重要的，c代码阶段就要用到了。留着下次分析吧。
