为什么我在构建 gdb 时找不到 termcap 库？

Question

make 然后失败了：

配置：错误：没有找到 termcap 库，但是 termcap 库就在那里，为什么找不到它？

我使用以下命令配置 gdb：

[mirror@hugemeow gdb-7.5]$ ./configure --libdir=/var/lib/gforge/chroot/home/users/mirror/ins/ins-gdb/lib/

configure: creating ./config.status
config.status: creating Makefile

当我配置为 gdb 时，该 tempcap 库就在那里：

[mirror@hugemeow gdb-7.5]$ ls /var/lib/gforge/chroot/home/users/mirror/ins/ins-gdb/lib/
libtermcap.a
[mirror@hugemeow gdb-7.5]$ ls /var/lib/gforge/chroot/home/users/mirror/ins/ins-gdb/include/
termcap.h

编辑 1：即使使用 --includedir 和 --libdir 选项也失败了...

[mirror@hugemeow gdb-7.5]$ ./configure --includedir=/var/lib/gforge/chroot/home/users/mirror/ins/ins-gdb/include/  --libdir=/var/lib/gforge/chroot/home/users/mirror/ins/ins-gdb/lib/
make

编辑 2：现在我按照 Patrice Tisserand 所说的进行构建，但也失败了，错误消息如下。

Answer 1

安装 libncurses 将解决您的问题。试试这个，如果你使用任何Debian的操作系统： sudo apt-get install libncurses5-dev。

Answer 2

./configure --includedir=/var/lib/gforge/chroot/home/users/mirror/ins/ins-gdb/include/  --libdir=/var/lib/gforge/chroot/home/users/mirror/ins/ins-gdb/lib/

--includedir和--libdir是安装目录的选项。

为了使用其他目录中的库，您可以尝试执行以下操作：

CFLAGS="-I/var/lib/gforge/chroot/home/users/mirror/ins/ins-gdb/include/" LDFLAGS="-L/var/lib/gforge/chroot/home/users/mirror/ins/ins-gdb/lib/" ./configure
