vajolet2 2.3 release

[Ras]

When I try to install libstc++ apt tells me it is already installed.

And what version? 3.4.22 or higher?

[Colin-G]

Thank you! Unfortunately I get a run-time error here

Code: Select all

volker@vp ~/Downloads $  ./vajolet2.2.3.linux
./vajolet2.2.3.linux: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by ./vajolet2.2.3.linux)

You need to use the "strings" command to find which versions of GLIBCXX you have support for

Code: Select all

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX

I am using an uptodate linux Mint 18.1, and running the string command as above shows I only have support up to GLIBCXX_3.4.21, not the required version 3.4.22, so I would not be able to compile it either on my current system.

This morning I have released the version 2.3 of Vajolet2.

It should be few elo point stronger than latest release and it's the first version thah can run on raspberry.

you can download it from here

Sorry to ask if this is the same version as the game on TCEC 10.

no it isn't, a new version has been submitted, but I think they have more or less the same strenght

linux version has been compiled in kubuntu 17.04 using the stndard tool. what distribution are you using?

can you try updating your distribution?

unfortunataly on linux I wasn't able to statically link the libraries, it it will no start the only solution is to build vajolet2 executable on your pc. I'll be glad to give you some info.

I tried it at different distros:

Linux Mint 18.2 which is based on Ubuntu. On that system the error occured first. The strings command suggested in another message in this thread delivers:

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX:

GLIBCXX_3.4
GLIBCXX_3.4.1

<... snip ...>

GLIBCXX_3.4.20
GLIBCXX_3.4.21
GLIBCXX_DEBUG_MESSAGE_LENGTH


So version 3.4.22 is missing here.

I tried it on openSuse 42.3 and Fedora 26 too. If I'm informed correctly Fedora is known to install the latest and greatest of whatever.

I also get errors on Fedora and Suse.

Fedora:
vpittlik@linux Downloads$ ./vajolet2.2.3.linux
Illegal instruction (Speicherabzug geschrieben)
vpittlik@linux Downloads$

Suse: same error message.

The string command on these distros do not deliver very useful information.

Fedora:
strings: '/usr/lib/x86_64-linux-gnu/libstdc++.so.6': No such file
Suse:
strings: command not found

I'm afraid I can't deliver more useful information.

You could try compiling it your own.

git clone https://github.com/elcabesa/vajolet
cd vajolet
git checkout vajolet2_2.3.2

Edit the makefile and remove -static

make
./vajolet2.exe

I am not sure if the version in the branch above is most recent one. The repository is bit messy.
