[ptxdist] Linker error on ArchLinux

[ptxdist] Linker error on ArchLinux

[Clemens Gruber]

Hi,

when building PTXdist 2017.10.0 on current ArchLinux, a linker error occurs:
/usr/bin/ld: lxdialog/checklist.o: undefined reference to symbol 'acs_map'
/usr/lib/libtinfo.so.6: error adding symbols: DSO missing from commandline

This occured after ArchLinux updated binutils to 2.29.1-1 and ncurses to
6.0+20170902-2.

I could work around it by adding -ltinfo to LDFLAGS in the PTXdist
Makefile.

Cheers,
Clemens

Strange. I have binutils 2.29.1-6 and ncurses 6.0+20170902-1 here on Debian
and it works just fine :-/. But:

$ cat /usr/lib/x86_64-linux-gnu/libncurses.so
INPUT(libncurses.so.5 -ltinfo)

I guess this is different for you...

We have some complex stuff in configure.ac to detect the curses library.
Maybe we should just require ncurses and use pkg-config.

Yes:
$ cat /usr/lib/libncurses.so
INPUT(-lncursesw)

Yes, pkg-config would have caught it:
$ pkg-config --libs ncurses
-lncursesw -ltinfo

I noticed in the meantime, that the package maintainer made a commit, which
fixes the problem too:
https://git.archlinux.org/svntogit/packages.git/commit/?h=packages/ncurses&id=987faeb8442d44e76a7a58642e8e6432eb220c25

Thanks,
Clemens

Ok, so it's no longer urgent. I still think we don't need to support
anything other than ncurses here, so I'd be happy to take a patch that
cleans this up and uses pkg-config.
