我对C没有太多经验，但是我正在尝试为ESP8266写一个基本的解释器，但是我无法编译它，这给了我一个错误，我无法修复。
这是我的代码：
static void testTimerCb(void *arg) {
webprog_init();
}
void user_init(void) {
...
os_timer_disarm(&testTimer);
os_timer_setfn(&testTimer, testTimerCb, NULL);
os_timer_arm(&testTimer, 10000, 0);
}
在另一个文件中：
void webprog_init(){
init("#1;2;0");
scanCommand();
print_result();
}
在另一个文件中：
#include <xml_parser.h>
#include <stdlib.h>
#include <mem.h>
#include <ctype.h>
#include "osapi.h"
char look[2] = "";
int indexx = 0;
char * input;
void init(char* code){
input = code;
indexx = 0;
next();
}
void next(){
if (indexx >= strlen(input))
{
look[0] = '\0';
}else{
look[0] = input[indexx];
indexx = indexx + 1;
}
}
Command scanCommand(){
Command c;
c.type = 0;
c.arg1 = 0;
c.arg2 = 0;
if (look[0] == '\0') {
return c;
}
else if (look[0] == '#') {
int delimiterCount = 0;
while (look[0] != '\0') {
switch (look[0]) {
case ';':
delimiterCount++;
break;
case '0':
case '1':
case '2':
case '3':
case '4':
case '5':
case '6':
case '7':
case '8':
case '9':
if (delimiterCount==0) {
c.type = appendCharToInt(c.type, look[0]);
}
else if(delimiterCount==1){
c.arg1 = appendCharToInt(c.arg1, look[0]);
}
else if(delimiterCount==2){
c.arg2 = appendCharToInt(c.arg2, look[0]);
}
else{
c.type = 0;
c.arg1 = 1;
c.arg2 = 0;
findEndOfCommand();
return c;
}
break;
case '$':
next();
return c;
//break;
default:
break;
}
next();
}
}
else{
c.type = 0;
c.arg1 = 2;
c.arg2 = 0;
return c;
}
return c;
}
int charToInt(char c){
return c-'0';
}
int appendCharToInt(int n, char c){
return n*10 + charToInt(c);
}
void findEndOfCommand(){
while (look[0] != '\0') {
if (look[0] == '$') {
next();
return;
}
next();
}
}
void print_result(){
while (look[0]!='\0') {
os_printf("%s, %d, %d, %c \n", token, kind, position, look[0]);
next();
}
}
错误是：
/卷/区分大小写/esp-open-sdk/xtensa-lx106-elf/lib/gcc/xtensa-lx106-elf/4.8.5/../../../../xtensa- lx106-elf / bin / ld： build / httpd.out部分
.text' will not fit in regioniram1_0_seg' collect2：错误：ld返回1退出状态make：*** [build / httpd.out] 错误1
我也正在使用esphttpd project，但是它可以工作，并且在我编写了上面的代码之后，它显示了此错误。我发现，当我注释掉scanCommand方法时，错误消失了。你能帮我吗？
编辑： 这是我的makefile的内容：
