Perché non riesco a trovare la libreria termcap quando creo gdb?

make e poi fallito con:

configure: error: nessuna libreria termcap trovata , ma quella termcap lib è proprio lì, perché non riesci a trovarla?

Configuro gdb con:

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

configure: creating ./config.status

quella libreria di Tempcap è proprio lì come ho configurato per 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

Modifica 1 : fallito, anche con opzione --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

Modifica 2 : Ora costruisco come ha detto Patrice Tisserand, ma ho anche fallito, con diversi messaggi di errore come segue.

L'installazione di libncurses risolverà il tuo problema. Prova questo se stai usando un qualunque sistema operativo Debian: sudo apt-get install libncurses5-dev.

./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 sono opzioni per installazione le directory.

Per poter utilizzare librerie da un'altra directory, puoi provare a fare quanto segue:

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 

Questo è stato estremamente utile: http://archive09.linux.com/feature/121735

Questo esempio mostra come avere successo quando trovi un target nativo   manca la libreria termcap (la costruzione incrociata è un po 'diversa qui   - usa ./configure --help in caso di dubbio):

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
