为ARM - Linux平台交叉编译Apache apr-util库

先发帖〜

我正在尝试将ActiveMQ-cpp客户端移植到ARM平台（Beaglebone / BeagleBoard） - 因为我正在我的PC上进行开发，所以我需要交叉编译ActiveMQ-cpp库以便它运行在ARM系统上 .

我按照building instruction中的步骤进行操作，除了使用以下代码编译APR和APR-util库：

对于APR：

./configure --prefix = / usr / arm-linux-gnueabi / apr --host = arm-linux-gnueabi CC =“arm-linux-gnueabi-gcc”CXX =“arm-linux-gnueabi-g”我跑make install，一切都很好 .

对于APR-util：

./configure --prefix = / usr / arm-linux-gnueabi / apr-util --host = arm-linux-gnueabi -with-apr = / usr / arm-linux-gnueabi / apr CC =“arm-linux- gnueabi-gcc“CXX =”arm-linux-gnueabi-g“我运行make install并得到了这个：

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

经过一番搜索，我认为'问题是libexpat是错误的格式（为i386编译？）

我的问题是：如何为ARM平台正确编译ActiveMQ-cpp库？有什么办法可以修复libexpat.so吗？或者跳过Apr-util？还是./configure中的Apr-util的一些选项？

后续：这是运行configure的日志文件：

从我所看到的，xml / expat配置正确 . 我想 - 也许我需要在gcc-arm-linux中编译expat库？我继续，做到这一点，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”

我在日志中得到了类似的结果，除了我现在有Expat 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，发生了同样的错误 .

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"libexpat.so"错误：centos 5.2 64bits，或者是Xeon 64bit的另一个案例 .

以下是实际导致错误的命令：
