libncurses.so link required to build util-linux

[Tiago Koji Castro Shibata]

While building util-linux-2.24.1 in SVN for the temporary system (step 5.33), make links using -lncurses. Since the links from ncurses to ncursesw are only created in step 6.21 (inside the final system), the compilation fails. Creating libncurses.so as a soft link to libncursesw.so before step 5.33 solves the problem: ln -s libncursesw.so $LFS/tools/lib/libncurses.so

Did you rebuild ncurses with --enable-widec as now specified in Chapter 5?

I'll leave open for a while until I get an answer. If not, I'll then close as invalid.

[Tiago Koji Castro Shibata]

Yes, and the wide character libraries were built. The problem is util-linux using -lncurses instead of -lncursesw. It can be solved with the links from 6.21, but they must be created before compilation.

My log has:

checking for NCURSESW... yes
checking ncurses.h usability... yes
checking ncurses.h presence... yes
checking for ncurses.h... yes

I don't have a verbose build log, but I got no failures. Perhaps this is a host issue. Does your host have /usr/lib/libncurses.so?

[Tiago Koji Castro Shibata]

The host has /usr/lib/x86_64-linux-gnu/libncurses.so. I'll build a clean LFS and get the logs (didn't save them, I feel stupid now). I had no problem in the configuration, only when linking to the library.

[Tiago Koji Castro Shibata]

Yeah, it's a host issue. ld from /tools isn't detecting the host's libraries. The following works:

LIBRARY_PATH=/lib/x86_64-linux-gnu:/usr/lib/x86_64-linux-gnu make

[bdubbs@…]

What host distro are you using? What are the contents of /etc/ld.so.conf?

The paths you mention are definitely non-standard. Perhaps the fix to #3482 fixes the issue.

[Tiago Koji Castro Shibata]

Distro is Lubuntu 13.04. The fix to #3482 proposed by pierre.labastie fixes the problems :) . /etc/ld.so.conf has "include /etc/ld.so.conf.d/*.conf" and the configuration files have:

/usr/lib/i386-linux-gnu/mesa
# Multiarch support
/lib/i386-linux-gnu
/usr/lib/i386-linux-gnu
/lib/i686-linux-gnu
/usr/lib/i686-linux-gnu
# libc default configuration
/usr/local/lib
# Multiarch support
/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu/mesa-egl
/usr/lib/x86_64-linux-gnu/mesa

That's weird. In any case, I'll close this as fixed.
