Linkg problem with lncurses

Submitted by iker on Wed, 2008-09-17 08:27

I am a new user to linux. I am using kubuntu.
I have installed Orocos 1.4.1 rtt and ocl.

I am trying to do the first examples: http://www.orocos.org/stable/examples/rtt/rtt-examples-1.4.0.tar.gz
I try to run simpletask. So I run: make
and returns this message.

g++ -o simpletask simpletask.o `PKG_CONFIG_PATH=/usr/local/lib/pkgconfig pkg-config orocos-ocl-gnulinux orocos-rtt-gnulinux --libs`
/usr/bin/ld: cannot find -l-lncurses
collect2: ld returned 1 exit status
make: *** [simpletask] Error 1

I have runned: ls /lib/*curses*
/lib/libncurses.so.4 /lib/libncurses.so.4.2 /lib/libncurses.so.5 /lib/libncurses.so.5.6 /lib/libncursesw.so.5 /lib/libncursesw.so.5.6

Does someone know how to fix it?

Thanks in advance

IIRC this was a bug in ocl 1.4.1

Probably your /usr/local/lib/pkgconfig/orocos-ocl-gnulinux.pc file contains a line "Libs:" where there is "-l-lncurses"
Replacing that by "-lncurses" should fix your problem.

hth,
