buildroot file system & cross compiling: dynamically linked application fails but static ok. How to link against uClibc
我有一个 buildroot 创建的文件系统，我正在尝试在 lighttpd 服务器上执行一些 c 代码。
我创建了一个简单的 C 模块，它只打印出几行 html。代码如下所示：
|
1
2 3 4 5 6 7 8 9 10 |
#include"stdio.h"
int main(void) { |
我正在使用来自 Ubuntu 存储库的编译器来编译它
但是在没有静态标志的情况下编译，执行失败如下：
|
1
2 |
# ./test.cgi
–sh: ./first.cgi: not found |
我想知道原因是否是 c 库错误，我应该链接到由 buildroot 编译的 uClibc。

要构建您的应用程序，您必须使用 Buildroot 生成的交叉编译器，位于
在这里，您使用的是 Ubuntu ARM 交叉编译器，它针对使用
只需使用 Buildroot 为您生成的交叉编译器即可。
