Apache交叉编译错误./gen_test_char：不能执行二进制文件 [英] Apache Cross Compilation Error ./gen_test_char: cannot execute binary file

问题描述

我看了很多时间找到这个bug的解决方案。当尝试交叉编译Apache的臂（我相信这可能发生在许多其他架构），我会得到这个错误从服务器文件夹中：

I looked quite some time to find a solution to this bug. When trying to Cross-Compile Apache for an Arm (I am sure that this could happen for many other Architectures), I would get this bug from with in the server folder:

 ./gen_test_char: cannot execute binary file

Apache正试图编译这个test_char.h生成器为实际的设备，而我需要它运行在我的Ubuntu，我是交叉编译。 Ubuntu不认可编译的gen_test_char作为可执行文件，所以我需要得到它正确编译Ubuntu。

This means that Apache is trying to compile this test_char.h generator for the actual device while I need it to run on my Ubuntu where I am Cross-Compiling. Ubuntu does not recognize the compiled gen_test_char as an executable so I need to get it compiled correctly for Ubuntu.

推荐答案

我搜索和搜索，发现几个尝试修补，但没有一个工作。这些大多数是直接从Apache开发组建议的补丁。

I searched and searched and found several tries to patch but none of them worked. Most of these were patches suggested directly from the Apache dev group.

但我终于遇到了这个 Apache邮件列表。它建议一个直接的解决方案，补丁不能提供。

But I finally came across this Apache mail list. It suggests a straight forward solution that the patches could not provide.

在尝试交叉编译Apache之前编译gen_test_char应用程序。所以我做了。

Compile the gen_test_char app before trying to cross-compile Apache. So I did. And followed the suggestions and it worked like a charm.

而是只是编译gen_test_char.c 1类似于：
gcc - Wall -O2 -DCROSS_COMPILE gen_test_char.c -s -o gen_test_char
然后运行它，并将其输出到include文件夹（或
放置normaly）;

instead just compile gen_test_char.c 1st with something like: gcc -Wall -O2 -DCROSS_COMPILE gen_test_char.c -s -o gen_test_char then run it and put its output into the include folder (or where its placed normaly);

之后，运行它以获得所需的输出：

and after this compilation run it to get the desired output with:

 ./gen_test_char > test_char.h
