ncurses库移植到arm平台

1、从ncurses官网下载源码 https://ftp.gnu.org/pub/gnu/ncurses/

2、解压后进入源码目录，初始化交叉编译环境，imx6系列的CPU初始化方法如下：

. /opt/fsl-imx-fb/4.1.15-2.1.0/environment-setup-cortexa9hf-neon-poky-linux-gnueab

查看配置参数 

tuo@ncurses-6.2$ echo $CONFIGURE_FLAGS 
--target=arm-poky-linux-gnueabi --host=arm-poky-linux-gnueabi --build=x86_64-linux --with-libtool-sysroot=/opt/fsl-imx-fb/4.1.15-2.1.0/sysroots/cortexa9hf-neon-poky-linux-gnueabi

 3、配置ncurses源码，可直接使用上述变量作为配置参数，由于默认使用系统自带的strip命令（X86-64）裁剪目标文件（ARM），会导致编译失败，这里先禁止使用strip命令裁剪（--disable-stripping）。如果因为存储空间有限，需要裁剪，可以在Makefile中指定使用arm-poky-linux-gnueabi-strip命令，或者等编译通过后，再手动用arm-poky-linux-gnueabi-strip命令裁剪，这里不过多展开。

tuo@ncurses-6.2$ ./configure $CONFIGURE_FLAGS --disable-stripping --prefix=/home/tuo/sdb1/ncurses-6.2/build --with-shared

 配置成功后的输出：

4、编译，make -j4，编译成功后输出：

5、make install

由错误日志

/opt/fsl-imx-fb/4.1.15-2.1.0/sysroots/x86_64-pokysdk-linux/usr/bin/tic: 1: /opt/fsl-imx-fb/4.1.15-2.1.0/sysroots/x86_64-pokysdk-linux/usr/bin/tic: Syntax error: word unexpected (expecting ")")
? tic could not build /usr/share/terminfo 

可知：tic命令格式不对，无法执行，这里要用系统自带的tic（x86），而不是交叉编译器的tic命令（arm）

PC中包含arm平台和本机x86平台的tic命令

 从PATH内容可以看出，/opt/.../usr/bin在PATH中的位置比/usr/bin前。因此，在搜索tic时，最先找到的是/opt/.../usr/bin/tic，而不是/usr/bin/tic，这才引起了先前的错误。解决方法：只要让先找到的tic是/usr/bin/tic就可以避免该错误。

6、make distclean后重新configure并make，然后继续make install，报错如下： 

查看系统的 ncurses版本：

 

不知道是不是跟系统的ncurses版本有关系，先换成5.9版本的ncurses源码编译：

1、前面步骤相同，当make 的时候，报错：

解决办法：

export CPPFLAGS="-P"

2、重新执行configure，make编译通过

3、 make install时报错：

 跟上面编译6.2版本的解决方法相同：

4、make distclean后重新configure并make，然后继续make install，编译通过：

5、验证输出文件是否为arm平台：

tuo@ncurses-5.9$ file build/lib/libncurses.so.5.9 
build/lib/libncurses.so.5.9: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, BuildID[sha1]=344449c1a62612c5f8c86dce8b7f7be9cd5eaf1d, not stripped

6、拷贝输出文件到交叉编译工具（方便移植其它库）及开发板的文件系统中：

tuo@ncurses-5.9$ sudo cp build/* /opt/fsl-imx-fb/4.1.15-2.1.0/sysroots/x86_64-pokysdk-linux/usr/ -rf
