avrdude: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

rm ~/.platformio/packages/tool-avrdude/avrdude
ln -s /usr/bin/avrdude ~/.platformio/packages/tool-avrdude/avrdude

Could you try to install lib32-ncurses package?

No difference, it is version 6, when then downloaded version is looking for
version 5.

Hi @James147
Do you have the same issue when you upload sketch through Arduino IDE?

Not with the one in the Arch User Repo, but it appears to replace the arduino provided avrdude with the working system one:

  # fix avrdude
  rm -f "${pkgdir}/usr/share/arduino/hardware/tools/avr/bin/avrdude"{,_bin}
  ln -s /usr/bin/avrdude "${pkgdir}/usr/share/arduino/hardware/tools/avr/bin/avrdude"

https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=arduino

So I assume that the official arduino build of avrdude does have the same problem.

@James147 I’ve just added to FAQ page info about the solution for this issue. If we recompile avrdude with the latest libncurses.so.6, it will not work with the rest Linux distributives (Debian, Ubuntu, etc.).

The idea with symbolic link is normal temporary solution.

I had to replace the avrdude installed by platformio with the system one, so

AVRDUDE=~/.platformio/packages/tool-avrdude/avrdude
rm $AVRDUDE
ln -s /usr/bin/avrdude $AVRDUDE

Thanks @cqql your solution works like a charm for me.

@ivankravets Thats the reason why linux distributions have a package manager. Either you ship the binary AND its dependencies or you let package manager do its work. Everything between is just a mess. So the obvious solution would be not to ship binaries at all!

In addition to what @mdaffin posted in the first comment, I had to link the avrdude of the toolchain-atmelavr to the new avrdude also, so I had to add these commands :

rm ~/.platformio/packages/toolchain-atmelavr/bin/avrdude
ln -s ~/.platformio/packages/tool-avrdude/avrdude ~/.platformio/packages/toolchain-atmelavr/bin/avrdude

Confirming that @Hamza5 ‘s addition did it for me. I ended up symlinking both locations, but it only worked upon the second (in toolchain-atmelavr as well as tool-avrdude.

I’m trying platformio on gentoo. Most ‘packages’ are broken in the same way:

piogdb: error while loading shared libraries: libncursesw.so.5: cannot open shared object file: No such file or directory

or

% ldd .platformio//packages/toolchain-gd32v/bin/riscv-nuclei-elf-gdb
linux-vdso.so.1 (0x00007ffe46d73000)
libncursesw.so.5 => not found

libgmp.so.10 => /usr/lib64/libgmp.so.10 (0x00007f67db261000)

So that issue is part of the PIO FAQ… I can’t really see a proper solution here. The AUR package is gone, the symlinks look like crude hacks…

By downloading the ncurses5-compat-libs & lib32-ncurses5-compat-libs from AUR, this issue was solved for me.
Should work on other distros by downloading these same packages from their specific package managers.
