Por que não consigo encontrar a biblioteca termcap quando eu construo o gdb?

Question

make e, em seguida, falhou com:

configure: error: nenhuma biblioteca termcap foi encontrada , mas a termcap lib está lá, por que não consegue encontrá-la?

Eu configuro o gdb com:

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

checking whether -fkeep-inline-functions is supported... yes
configure: creating ./config.status
config.status: creating Makefile

que a biblioteca tempcap está lá quando configurada para o gdb :

[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

Editar 1 : falhou, mesmo com a opção --includedir e --libdir ...

[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
    checking for library containing tgetent... no

Editar 2 : Agora eu construo como Patrice Tisserand disse, mas também falhei, com mensagem de erro diferente da seguinte forma.

Answer 1

Instalar o libncurses irá resolver o seu problema. Tente isto se você estiver usando qualquer sistema operacional Debian: 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 e - libdir são opções para diretórios de instalação .

Para usar bibliotecas de outros diretórios, você pode tentar fazer o seguinte:

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

Isso foi extremamente útil: link

This example shows how to succeed when you find a target-native termcap library is missing (cross building is somewhat different here -- use ./configure --help when in doubt):

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
