I just installed the 1.6.7 version and want to upload it a sketch to Arduino UNO hardware. I get error message:

/home/pali/Irataim/TarBalls/Arduino/arduino-1.6.7/hardware/tools/avr/bin/avrdude: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

I'm on Gentoo linux operating system.

How can I solve this problem?

By following this link:

I just add tinfo USE flag to ncurses package, re-emerged it and can run Arduino IDE that I emerged from Gentoo repository.

  • (Install dependencies with emerge -avq sun-jre-bin crossdev) Run equery belongs libtinfo.so , if the library exists then try symlinking the libraries: ln -s /lib64/libncurses.so.5 /usr/lib/libtinfo.so.5 and ln -s /usr/lib/libtinfo.so.5 /usr/lib/libtinfo.so.

  • I did so, but there is no libtinfo.so library.

  • equery belongs libtinfo.so there is none?

Install libtinfo5, the terminfo library.

If that doesn't help, you can try to debug the problem yourself. First, check which libtinfo avrdude is looking for:

ldd arduino-1.7.8-linux64/hardware/tools/avr/bin/avrdude_bin | grep libtinfo

On my Ubuntu, I get this:

libtinfo.so.5 => /lib/x86_64-linux-gnu/libtinfo.so.5 (0x00007fa74a888000)

Next, see where your libtinfo is installed:

find /lib /usr/lib -name 'libtinfo*'

On my system I get:


Do you have any discrepancy between the two?

  • I just installed terminfo package, the Haskell bindings to the terminfo library and try to upload again a sketch. I get the same error message: arduino-1.7.8-linux64/hardware/tools/avr/bin/avrdude: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory. However, I'm using now the just downloaded arduino-1.7.8-linux64 package.

  • @PalCsanyi: Then I do not have the solution, but I added some hints to help you debug the problem. Mar 2 '16 at 19:03
  • I tried followings on my Gentoo linux: ldd arduino-1.7.8-linux64/hardware/tools/avr/bin/avrdude not a dynamic executable find /lib /usr/lib -name 'libtinfo*' There is no output.

  • @PalCsanyi this topic refers to have similar problem and got it solved using a symbolic link to libncurses. Take look: forums.gentoo.org/…

You have to rebuild sys-libs/ncurses with tinfo USE flag turned on. (You can also make a symlink: libtinfo.so -> libncurses.so, but it's not elegant solution).

Firstly, check if you have a record for ncurses in any file in /etc/portage/package.use. If not, create a file /etc/portage/package.use/ncurses with such content:

sys-libs/ncurses tinfo

then, rebuild ncurses:

emerge -av sys-libs/ncurses
