Xively C库与ubuntu eclipse（gcc/g+；+；）32位交叉编译应用程序连接

我已经优化了运行64位机器的Ubuntu13.04，以交叉编译32位ARM，并通过开发c/c++代码检查代码是否在32位ARM上成功运行（BBBlack）。现在我想要实现的是与Xively服务器的连接，从数据流更新和检索提要/数据点

因此，我想在我的Ubuntu eclipse开发环境中使用Xively中的c库它能工作吗？

是否会出现交叉编译问题？或一切正常吗？

以下是我运行>>make-csrc CC=arm-linux-eabi-gcc-AR=arm-linux-eabi-gcc示例时得到的信息

Xively C库应适用于任何32位和64位POSIX操作系统，以及带有lwIP的各种RTO

要使用

arm linux eabi gcc

交叉编译库，需要在顶级目录中运行以下命令：

make -C src CC=arm-linux-eabi-gcc AR=arm-linux-eabi-gcc libxively
make -C src CC=arm-linux-eabi-gcc AR=arm-linux-eabi-gcc examples

详细说明 下面我将描述如何编译一个简单的示例C程序，并将其与Xively库静态链接。这应该提供足够的背景信息。尽管如此，我不能提供关于如何修复EclipseIDE的信息，因为我怀疑这是可能的

创建目录并克隆库：

mkdir hello_xively
cd hello_xively
git clone --recursive https://github.com/xively/libxively

现在添加

test.c

文件，如图所示：

#include "xively.h"

int main() {

  xi_context_t* ctx = xi_create_context( XI_HTTP, "DUMMY_API_KEY_STRING", 123 );
  xi_delete_context( ctx );
  return 0;
};

构建库本身（请注意，目标的

CC

和

AR

值可能不同）：

编译test.c，并将其与静态库链接：

$CC test.c \
  -I./libxively/src/libxively \
  libxively.a -o xively_static_test

---

您现在可以尝试将

xively\u static\u测试

可执行文件复制到目标设备的文件系统并执行它，因为这是一个测试示例，因此不会产生任何输出。不，您可以扩展上述示例以提供所需的功能

所以我只需要做一次就可以了，这个Xively C库已经配置好了吗？并以Conevential的方式将其添加到linux？好吧，如果您不对库进行更改，那么您就不需要重新构建它。否则，您需要教导您的IDE这是干净构建的一部分。因此，通常您希望使您的IDE链接到静态库，您可以在

libxively/src/obj/libxively.a

下找到它。我的意思是什么样的库。C语言的扩展？我运行了make-C src CC=arm linux eabi gcc AR=arm linux eabi gcc libxively和make-C src CC=arm linux eabi gcc AR=arm linux eabi gcc示例，但感觉这些语句已经完成了我在libxively目录中运行“makeall”，在上面添加了返回提示

$CC test.c \
  -I./libxively/src/libxively \
  libxively.a -o xively_static_test
