Trouble with compiling Allegro 4.9

Hello all,

I am trying to get Allegro up and running and have run into some trouble.
I am using Ubuntu 8.10

So far I have:
- Installed subversion and cmake
- Used svn to get the allegro source
- Installed the packages: zlib1g-dev, libpng12-dev, libfreetype6-dev, libvorbis-dev, libx11-dev, libxcursor-dev, libxxf86vm-dev, libasound2-dev, libjack-dev
- Used cmake to make the build files

All this has gone smoothly from what I can see.
Now I am trying to compile Allegro and am getting an error:

~/allegro/4.9/Build $ sudo make

Something to do with fonts? I have no idea. Would really appreciate some help if anyone could spare the time

I don't think it has anything to do with you, but I haven't found the problem yet either.
The error message is caused by a #define near the top of that source file that #defines away strlen() (to discourage its use because using it in this context is likely to be a bug, apparently). I get the impression that your C compiler is doing a macro expansion that inserts a call to strlen().
You can comment out the #define for now, that should fix the problem temporarily.

EDIT: well, no explicit calls to strlen anywhere. I'm guessing your compiler (what version do you have?) #defines strcmp(s1,s2) as strncmp(s1,s2,min(strlen(s1), strlen(s2)) or something to that effect. Could you check this?
I'll remove the #define for the time being (so the problem should then be fixed in svn).

I noticed this today and committed the same fix to my git repository but evidently forgot to propagate that to svn, sorry.

No problem, it was an easy fix.
I opted for commenting out the line and adding a comment in favour of removing it completely, but that's probably what we should do before 5.0 release anyway.

Oh I see, I will try this tonight and also check my compiler version. Thanks heaps for the help

EDIT:
I have GCC 4.3.2 if you still wanted to know.
It compiles and installs correctly now, thanks again for the help, appreciate it.
