交叉编译Apache用于ARM APR-util的库 - Linux平台

Question

的第一篇文章〜

我试图端口的ActiveMQ-CPP客户到ARM平台（Beaglebone/BeagleBoard的） - 因为我做我的开发在我的PC上，我需要交叉编译ActiveMQ-cpp库才能在ARM系统上运行。

我按照通过在其building instruction的步骤，不同之处予编译APR和APR-util的文库使用如下：

对于APR：

的./configure前缀=的/ usr /臂-linux-gnueabi/apr --host = arm-linux-gnueabi CC =“arm-linux-gnueabi-gcc”CXX =“arm-linux-gnueabi-g ++” 我运行make install，事情都很好。

对于APR-util的：

的./configure前缀=/USR /臂-Linux的gnueabi/APR-util的--host =臂-Linux的gnueabi -with-APR =的/ usr /臂-linux-gnueabi/APR CC = “武装-Linux的gnueabi-GCC” CXX = “武装-Linux的gnueabi-G ++” 我运行make安装并得到这个：

/home/peter/apache/Apache_apr/apr-util-1.5.1/xml/expat/.libs/libexpat.so: could not read symbols: File in wrong format 

一些搜索后，我认为”这个问题是在的libexpat格式错误作为

我的问题是（编译i386的？）：如何我正确编译的ActiveMQ-CPP库甲A RM-平台？有什么方法可以修复libexpat.so吗？或跳过Apr-util？或者Apr-util的./configure中的一些选项？

从我所看到的，XML /外籍配置正确。我想 - 也许我需要在gcc-arm-linux中编译expat库？我继续这样做，然后再次运行配置：

./configure --prefix =/usr/arm-linux-gnueabi/apr-util --host = arm-linux-gnueabi -with-apr =/usr/arm-linux-gnueabi/apr -with-expat =/usr/arm-linux-gnueabi/expat CC =“arm-linux-gnueabi-gcc”CXX =“arm-linux-gnueabi-g ++”

我得到了类似的结果在日志中，除了我现在有外籍1.95.x：

checking for odbc/sql.h... no 
    setting LDFLAGS to "-L/usr/arm-linux-gnueabi/expat/lib" 
    adding "-I/usr/arm-linux-gnueabi/expat/include" to CPPFLAGS 
    setting APRUTIL_INCLUDES to "-I/usr/arm-linux-gnueabi/expat/include" 
    setting APRUTIL_LDFLAGS to "-L/usr/arm-linux-gnueabi/expat/lib" 
checking Expat 1.95.x... yes 
    setting APRUTIL_EXPORT_LIBS to "-lexpat" 
    setting APRUTIL_LIBS to "-lexpat" 

运行make，发生同样的错误。

我搜索了与libexpat.so相关的错误。我注意到那些想要交叉编译的人通常会看到这个“libexpat.so”错误：centos 5.2 64bits，或至少64位的其他情况。

下面是实际导致错误的命令：

非常感谢您的帮助！

Answer 1

看来你有一些图书馆建立在不同的格式。由此你得到的错误： 文件格式错误 collect2：ld返回1退出状态 运行文件命令通过/usr/arm-linux-gnueabi/expat/lib/libexpat.so 如果它显示了一些不同格式，那么你需要重建它。 但它的奇怪，因为我认为它是一个预先建立的手臂库，它应该是在正确的格式。
