如何为ARM arch交叉编译Microwindows

对Microwindows的交叉编译有一些问题。 以下是我的步骤： 0下载交叉编译工具链

wget http://www.codesourcery.com/sgpp/lite/arm/portal/package5383/public/arm-none-linux-gnueabi/arm-2009q3-67-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 sudo mkdir –p /opt/toolchain sudo cp arm-2009q3-67-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 /opt/toolchain cd /opt/toolchain sudo tar –jxvf arm-2009q3-67-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 export PATH=/opt/toolchain/arm-2009q3/bin:$PATH 跑牌 之后，我有下一条消息：

怎么回事？如何修复它？

首先，您需要所有依赖项库的源代码，并交叉编译libjpeg-dev-libpng-dev-python-dev-libfreetype6-dev和其他依赖项库

---

然后，在编译microwindow时，必须在交叉编译库所在的Makefile中更新include和library的路径。

您正在为include目录指定主机的环境，即本地环境，而不是目标环境。你以前有没有用你的工具链交叉编译过其他东西，例如hello_world.c？考虑使用开发环境，比如OpenCube。是的，Hello World和我的工具链中的一些其他源编译成功。谢谢 sudo apt-get install libjpeg-dev libpng-dev python-dev libfreetype6-dev cd microwindows-0.92/src nano config
