ncurses error when using binary

[faddat]

This release:

https://github.com/mimblewimble/grin/releases/tag/v0.4.2

When using the v0.4.2 binary, I get the following ncurses error:

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

I don't get this error when building using cargo from source code. When I build it myself Grin works just fine :). Arch Linux. Happy to investigate further.

Hey @faddat, just curious if you tried to install ncurses on your Arch linux?

[tsusanka]

I believe this is because Arch Linux has already the newer version of libncursesw.so - libncursesw.so.6:

$ ls /usr/lib/libncursesw.so.6
/usr/lib/libncursesw.so.6
$ ls /usr/lib/libncursesw.so.5
ls: cannot access '/usr/lib/libncursesw.so.5': No such file or directory

Creating a simlink 6 -> 5 works just fine:

ln -s /usr/lib/libtinfo.so.6 /usr/lib/libtinfo.so.5

and exactly the same goes for /usr/lib/libtinfo.so. Grin lunches just fine after these fixes

I installed 5 on a vultr server running Ubuntu 18.xx, still get the error. Not paying attention thought I might need the newer 6.1, so compiled and installed. Same error of course and the simlink back to 5 still gives initial error. Going to try rolling back to good old 16.xx I think.

[Lazydayz137]

Works like a charm, no ncurses install required(5 already there) on a Vultr Ubuntu 16.04 clean install w/upgrades. Just as an update to my previous comment. Doesn't change OP issue.

[jeroenev]

same issue here, grin 1.0.1
using Manjaro (arch based)

[jasonzhouu]

fixed this problem in ubuntu 18.10, grin 1.0.1:

cd /lib/x86_64-linux-gnu
ln -s libncursesw.so.6 libncursesw.so.5
ln -s libtinfo.so.6 libtinfo.so.5

in ubuntu 18.04, this problem don't exist, and these two file is appeared in version 5.

[jeroenev]

cding into /usr/lib/ and using your symlink commands from there seems to solve the issue on manjaro (and probably Arch as well)

[quentinlesceller]

Looks like the a distro related error and not a grin error itself. Closing.

[jeroenev]

Seems to me like an issue with grin not recognizing libncurse version 6, only version 5
Once ubuntu updates to v6 this issue will also occur there

[jeroenev]

Seems like it already occurs in version 18.10 reading the comments above

After making the link, it comes with another error:

Segmentation fault (core dumped)

[jeroenev]

@cool007zqw try the code from jasonzhouu, that fixed the errors for me on Manjaro

fixed this problem in ubuntu 18.10, grin 1.0.1:

Ubuntu 19.04
Fix for me !
Thx

[FTLIan]

I am on Ubuntu 19.04 and the symlinks have not solved the problem for me. After running the above commands, trying to run grin gives me these errors:

./grin: /lib/x86_64-linux-gnu/libtinfo.so.5: version NCURSES_TINFO_5.0.19991023' not found (required by ./grin)
./grin: /lib/x86_64-linux-gnu/libncursesw.so.5: versionNCURSESW_5.6.20061217' not found (required by ./grin)
./grin: /lib/x86_64-linux-gnu/libncursesw.so.5: version `NCURSESW_5.1.20000708' not found (required by ./grin)

Thank you for any help you can provide.

[quentinlesceller]

Hi @FTLIan, I will spin up a 19.04 VM and see if I can help you.

[quentinlesceller]

Hi @FTLIan unfortunately I was not able to run the binaries on Ubuntu 19.04. I opened the following issue #3022.

[Sky-Bly]

Resolves:

sudo apt-get install -y libncursesw5

[lehnberg]

@quentinlesceller I just encountered this issue as well (Debian Buster) with newer versions of libncurses already installed on the system.

@Sky-Bly's fix worked for me (thanks for that)

sudo apt-get install -y libncursesw5

...but I would tend to agree with @jeroen7s's comment above:

Seems to me like an issue with grin not recognizing libncurse version 6, only version 5

Would be nice if we could get this addressed somehow, I don't think it's obvious for end users that they need to have a specific older version of ncurses installed in order for the binary to work. Perhaps makes sense to reopen?

[slicken]

I agree, fixing small things like this matter
easy to install/use, with no hurdles is good for adoption

[quentinlesceller]

I'll take a look.

[quentinlesceller]

To clarify: the issue is with the linking of libncursesw-6 which is the wide character library. This looks similar to jeaye/ncurses-rs#151.
However since we are using cursive might be something related to gyscos/cursive#411. We are however using an old version of Cursive 0.12 instead of 0.14.

[quentinlesceller]

Since libncursesw5 and libncursesw6 uses the same API. Doing an

apt install libncurses5

on Ubuntu solved it (tested on Ubuntu 20.04). I expect it to be the same on other distros.
