Details on this package are located in Section 8.28.2, “Contents of Ncurses.”
The Ncurses package contains libraries for terminal-independent handling of character screens.
First, ensure that gawk is found first during configuration:
sed -i s/mawk// configure
Then, run the following commands to build the “tic” program on the build host:
mkdir build pushd build ../configure make -C include make -C progs tic popd
Prepare Ncurses for compilation:
./configure --prefix=/usr \ --host=$LFS_TGT \ --build=$(./config.guess) \ --mandir=/usr/share/man \ --with-manpage-format=normal \ --with-shared \ --without-normal \ --with-cxx-shared \ --without-debug \ --without-ada \ --disable-stripping \ --enable-widec
The meaning of the new configure options:
--with-manpage-format=normal
This prevents Ncurses installing compressed manual pages, which may happen if the host distribution itself has compressed manual pages.
--with-shared
This makes Ncurses build and install shared C libraries.
--without-normal
This prevents Ncurses building and installing static C libraries.
--without-debug
This prevents Ncurses building and installing debug libraries.
--with-cxx-shared
This makes Ncurses build and install shared C++ bindings. It also prevents it building and installing static C++ bindings.
--without-ada
This ensures that Ncurses does not build support for the Ada compiler which may be present on the host but will not be available once we enter the chroot environment.
--disable-stripping
This switch prevents the building system from stripping the programs using strip program from the host. Using host tools on cross-compiled program can cause failure.
--enable-widec
This switch causes wide-character libraries (e.g.,
libncursesw.so.6.3
) to be built
instead of normal ones (e.g., libncurses.so.6.3
). These wide-character
libraries are usable in both multibyte and traditional 8-bit
locales, while normal libraries work properly only in 8-bit
locales. Wide-character and normal libraries are
source-compatible, but not binary-compatible.
Compile the package:
make
Install the package:
make DESTDIR=$LFS TIC_PATH=$(pwd)/build/progs/tic install echo "INPUT(-lncursesw)" > $LFS/usr/lib/libncurses.so
The meaning of the install options:
TIC_PATH=$(pwd)/build/progs/tic
We need to pass the path of the just built tic able to run on the building machine, so that the terminal database can be created without errors.
The libncurses.so
library is
needed by a few packages we will build soon. We create this
small linker script, as this is what is done in Chapter 8.
