如果stdlib.h文件存在但编译器仍然报错,可能是编译器的包含路径设置不正确。你可以通过检查编译器的命令行选项或环境变量来确认包含路径。例如,在使用GCC编译时,你可以通过-I选项来指定额外的包含路径: bash g++ -I/usr/include your_file.cpp -o your_program 重新编译代码: 在进行了上述更改后,尝试重新编译你...
对比上面的正常情况,这种情况下为什么会出错,就很好理解了:因为在搜索列表中,/usr/include被移到了/usr/include/c++/7之前,所以在/usr/include/c++/7/cstdlib中遇到#include_next<stdlib.h>,就找不到stdlib.h了。 解决方法 事实上,/usr/include(交叉编译情况下是sysroot/usr/include)本来就在编译器默认的搜索...

int main(int argc, const char *argv[]) { return 0; } 在vim中打开该文件,通过ycm添加的YcmDiags命令,可以看到错误中有下面信息,直观的说就是cstdlib这个文件包含的stdlib.h文件找不到 1 /include/c++/7/cstdlib|75 col 15 error| 'stdlib.h' file not found 2 /include/c++/7/bits/std_abs.h|38...
CC++STL之#includecstdlib头⽂件在进⾏编程时,有时需要⽤到头⽂件cstdlib中的⽅法，cstdlib中⽅法有如下类型：<1> 字符串转换 atof: 字符串转浮点型；atoi：字符串转整型；atol：字符串转长整型 #include <stdio.h> #include <stdlib.h> int main (){ char str[] = "256";int f_result, ...
注意到 2 跟 3 会有一些交集，比如 C 的 <stdlib.h> 与 C++ 的 <cstdlib>，选哪个都可以，保持...
