Help with GIT

[ctdabomb]

ST just moved from svn to git a few days ago and the link on the wiki hasn't been updated. here is the correct one: http://code.google.com/p/supertux/
unfortunately you are right about the last commit being sept. 11

[LMH]

By the way, I just found out that not all the files made it over to git. Until it is fixed you can use a clone that I've begun working with (accessible through the Google Code link).

[Sauer2]

Thanks.
So i think i better wait until the transfer is completed.

[ctdabomb]

well the transfer is completed. If you use LMH's clone

[Sauer2]

OK, thanks, i'll take a look tomorrow, then.

[ctdabomb]

cool

[Sauer2]

Well, actually i tried today and it didn't compile because of errors, so i think i will wait until LMH is finished with extending the code.

[LMH]

I've had no problems getting the code to build. You're likely missing one of the requisite libraries (see the REQUIREMENTS section of the INSTALL file). There are a slew of them, and if I remember right it was a pain getting my system to the point where I could actually use the code. You can probably figure out what is missing by the error code, and you may also need to refer to the wiki as well.

I wish I had made a list of all the things I did that ultimately led to my first successful build (being a novice it probably would have been useful for others), but I didn't have that foresight (wasn't even sure if I'd ever be able to do it). The hardest part is making sure all the prerequisites are in place, which is also highly dependent on your OS.

[ctdabomb]

you guys were lucky, I wasn't even able to get the code itself!I stink at that sort of stuff)

[Sauer2]

It doesn't look like an dependency error, since cmake was completed without missing dependencies. That's the message:

{l Code}: {l Select All Code}

/home/sauer2/lmh0013-clone/src/object/bonus_block.cpp: In member function ‘void BonusBlock::try_open(Player*)’:

@ctdabomb: Are you using linux and have git installed?
Then use

{l Code}: {l Select All Code}

git clone https://code.google.com/r/lmh0013-clone/

to get the repository folder.
On windows you can you TortoiseGit, i suppose.

[ctdabomb]

i wasn't sure what people meant when people said ""do you have git installed?" so I installed some programs that said they were a git repository browser, but i couldn't figure out how to use them. so I am stuck.

[ctdabomb]

I tried something called gitg, but when I open it it says: Could not find git repository.

[Sauer2]

I think, gitg is just a viewer for repositiories, that you already have cloned to your pc.
To clone the repository from google code, open a command line window like terminal or xterm and run

{l Code}: {l Select All Code}

git clone https://code.google.com/r/lmh0013-clone/

.
It creates a folder in your user directory where all the code, gfx and stuff lies.

[ctdabomb]

oh! I get it now! i am very stupid :P

[LMH]

It doesn't look like an dependency error, since cmake was completed without missing dependencies. That's the message:

It looks like it might be something I did (although I don't understand why it worked for me). Can you try using the revision before the bonusblock changes? That might fix it. In the mean time I'll try to find out what went wrong with my code (alternatively just copy the external/tinygettext directory from my clone over to the official supertux files and avoid all my tinkering).

[Sauer2]

Maybe it's a different-compiler thing. I use g++ 4.6.2.

[Sauer2]

Question aside: How do i clone an earlier revision? I searched the web for a time, but i only find stuff like rolling back and pulling older files...

[LMH]

No need to clone again, just use:

{l Code}: {l Select All Code}

git reset --hard <tag/branch/commit id>

or in this case:

{l Code}: {l Select All Code}

git reset --hard 73380d492ba0

[Sauer2]

OK, that works. Thanks!

[ctdabomb]

I am trying to compile this, but I get these cmake errors.

{l Code}: {l Select All Code}

[LMH]

Looks like CMake cannot find OpenAL and PhysicsFS. You'll probably want to try to re-install them. If they continue to give you trouble, you might have to look around for a different source for these libraries appropriate for your OS.

Getting those pesky prereqs working correctly is the toughest part of building from code.

[ctdabomb]

thanks,

[ctdabomb]

I reinstalled them, and that didn't work so I installed the newest versions from their websites, but that failed also, both times getting the same error as before.

[LMH]

ugh.. I think there is a way to manually tell CMAKE where things are, but I'm not sure off the top of my head how to do it.

I was looking at the building wiki page and saw that the development versions of those libraries are required. Perhaps you only installed the standard installations, although I would probably expect a different error if that were the case. I'm not sure if there are any hints on that page that will help you. Otherwise you'll probably have to search CMake, OpenAL, and PhysicsFS documentation and hope someone somewhere has the solution. I'm no expert on these things so I'm afraid that my usefulness is rather limited.

[ctdabomb]

oh well. I guess I will wait for a miracle to happen or 4.0 release.
