ncurses交叉编译

1.环境

编译环境：ubuntu18.04虚拟机

板端：移远AG550平台编译链aarch64-oe-linux

2.ncurses下载

ncurses库下载地址：Index of /pub/gnu/ncurses

下载5.9的版本

3.解压并且编译 tar xvf ncurses-5.9.tar.gz cd ncurses-5.9

执行configure命令后出现如下错误：

./configure --prefix=/home/share/work/code/v2xapp_ql/v2xstack/opensource/ncurses-5.9/install --host=aarch64-oe-linux --with-shared configure: WARNING: If you wanted to set the --build type, don't use --host. If a cross compiler is detected then cross compile mode will be used. configure: loading site script /opt/ag215_crosstools/crosstools/site-config-aarch64-oe-linux checking for egrep... grep -E Configuring NCURSES 5.9 ABI 5 (Wed Dec 7 20:38:01 CST 2022) checking build system type... x86_64-unknown-linux-gnu checking host system type... Invalid configuration `aarch64-oe-linux': machine `aarch64-oe' not recognized configure: error: /bin/sh ./config.sub aarch64-oe-linux failed

其中： –prefix 是指定生成文件的路径 –host 指定的是交叉编译工具链的前缀 –with-shared 生成动态库

解决方法：

sudo apt-get install libtool cp /usr/share/libtool/build-aux/config.sub . cp /usr/share/libtool/build-aux/config.guess .

安装后配置完成

make编译出现错误

In file included from ../ncurses/curses.priv.h:283, from ../ncurses/lib_gen.c:19: _91379.c:835:15: error: expected ‘)’ before ‘int’ ../include/curses.h:1594:56: note: in definition of macro ‘mouse_trafo’ #define mouse_trafo(y,x,to_screen) wmouse_trafo(stdscr,y,x,to_screen) ^ Makefile:794: recipe for target '../obj_s/lib_gen.o' failed make[1]: *** [../obj_s/lib_gen.o] Error 1 make[1]: Leaving directory '/home/share/work/code/v2xapp_ql/v2xstack/opensource/ncurses-5.9/ncurses' Makefile:109: recipe for target 'all' failed make: *** [all] Error 2

解决方法：

根据出错提示，找到ncurses目录下，include文件夹里的curses.h文件，查找mouse_trafo，锁定在1584行： 1583 extern NCURSES_EXPORT(bool) wmouse_trafo (const WINDOW*, int*, int*, bool); 1584 extern NCURSES_EXPORT(bool) mouse_trafo (int*, int*, bool); /* generated */ 应该是由后面的一行注释引起的，具体原因不详。由于代码的部分是由另一个文件curses.tail导入的，所以要修改curses.tail： sudo vim curses.tail 查找mouse_trafo，定位到104行，去除104行后面的注释： 103 extern NCURSES_EXPORT(bool) wmouse_trafo (const WINDOW*, int*, int*, bool); 104 extern NCURSES_EXPORT(bool) mouse_trafo (int*, int*, bool); /* generated */ 保存后退出，重新make即可。

make后还是出现错误：

../c++/cursesp.h: In member function ‘T* NCursesUserPanel::UserData() const’: ../c++/cursesp.h:256:43: error: no matching function for call to ‘NCursesUserPanel::get_user() const’ return reinterpret_cast(get_user ());

网上搜索后发现：

出错的原因是编译器版本过高。解决方法有两个，一是更新ncurses到6.2版本，或者降低编译器版本。

下载6.2版本的源码重新按照上面的步骤编译一次，就可以完成编译了。
