make然后失败了：

我使用以下命令配置 gdb：

configure: creating ./config.status

当我配置 gdb 时，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/

编辑2：现在我按照 Patrice Tisserand 所说的进行构建，但也失败了，并出现了如下不同的错误消息。

答案1
安装 libncurses 将解决您的问题。如果您使用任何 Debian 操作系统，请尝试此操作：
sudo apt-get install libncurses5-dev。
答案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是选项安装目錄。
为了使用来自其他目录的库，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

这非常有帮助：http://archive09.linux.com/feature/121735
此示例显示了当您发现缺少目标本机 termcap 库时如何成功（这里的交叉构建略有不同 - 如有疑问，请使用 ./configure --help）：
cd ~/work/cross/gdb/downloads wget ftp://ftp.gnu.org/gnu/termcap/termcap-1.3.1.tar.gz cd .. tar xvzf downloads/termcap-1.3.1.tar.gz mkdir -p ~/work/cross/gdb/build/termcap cd ~/work/cross/gdb/build/termcap export CC=powerpc-7450-linux-gnu-gcc export RANLIB=powerpc-7450-linux-gnu-ranlib ../../termcap-1.3.1/configure --host=powerpc-7450-linux-gnu --prefix=$HOME/work/cross/termcap make make install
答案4
对于最后一个错误編輯2，
$ mkdir newbuild
$ 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
$ make
或者您可以先运行以前的配置命令，make distclean然后重试。
