Game crashes after death

[themightyglider]

I got the source code from the games website and compiled/installed it on my GNU/Linux system like described in INSTALL.
The game runs fine but if I die it crashes and throws this error message:

Can't open /usr/local/var/ivan/ivan-highscore.scores for output!

I checked the path on my system but it does not exist.

That is because the game does not have privileges to create the directory.

Try this on the terminal:
$ sudo mkdir -p /usr/local/var/ivan
$ sudo chmod 766 /usr/local/var/ivan

Thank you very much for the quick help!

I expected the game to run properly if I follow the instructions. If this steps are necessary they should be mentioned in INSTALL.

[Larzid]

I believe that it should be done by the make install script. I haven't learned how those work yet, else I would have already made a pull request.

The two commands you mentioned above only solved the problem if I run IVAN with root privileges ($ sudo ivan). You also need to give your user account write access to

/usr/local/var/ivan/ivan-highscore.scores

Thanks for reporting. Definitely a bug in how the game is being installed by CMake.

I believe this should be fixed by specifying the appropriate permissions in this CMake install command:

ivan/CMakeLists.txt

Line 16 in 931329d

install(DIRECTORY Graphics Script Music DESTINATION "${CMAKE_INSTALL_DATADIR}/ivan")

Can you test if adding something along the lines of DIRECTORY_PERMISSIONS OWNER_READ OWNER_WRITE OWNER_EXECUTE GROUP_READ GROUP_WRITE WORLD_READ WORLD_WRITE to the arguments of install and doing a fresh install fixes the issue for you?

Hello emlai.

I tried adding the line as you suggest, but I get an error when I run cmake

This is how I edited the line:
install(DIRECTORY Graphics Script Music DESTINATION "${CMAKE_INSTALL_DATADIR}/ivan" PERMISSIONS OWNER_READ OWNER_WRITE OWNER_EXECUTE GROUP_READ GROUP_WRITE WORLD_READ WORLD_WRITE)

and this is the error I get:
CMake Error at CMakeLists.txt:12 (install):
install DIRECTORY does not allow "PERMISSIONS" before a PATTERN or REGEX is
given.

themightyglider:

try:
$ sudo chmod -R 776 /usr/local/var/ivan
$ sudo groupadd -f games
$ sudo chgrp -R games /usr/local/var/ivan
$ sudo usermod -a -G games your-username

as a last resort you could try:
$ sudo chmod 777 /usr/local/var/ivan
however many people will warn you against this last command since it gives read write and execute rights to everybody.

@Larzid It should be DIRECTORY_PERMISSIONS instead of just PERMISSIONS for install(DIRECTORY ...).

[Larzid]

I corrected the line to:
install(DIRECTORY Graphics Script Music DESTINATION "${CMAKE_INSTALL_DATADIR}/ivan" DIRECTORY_PERMISSIONS OWNER_READ OWNER_WRITE OWNER_EXECUTE GROUP_READ GROUP_WRITE WORLD_READ WORLD_WRITE)

but now the game won't run:
$ /usr/local/bin/ivan
File /usr/local/share/ivan/Script/define.dat not found!

#490 could be a solution for this issue.

After #496, the bone files and highscore file are stored in ~/.ivan too, but you need to manually move the old files from /usr/local/var/ivan/ into it.
