Aliens vs Predator Linux enhanced with cutscene support and new screen resolutions

avp's Issues

RE: Compiling the game

I can see there's a few people struggling to get this working so I thought I'd post as I've had no trouble getting it to compile.

These instructions relate to Debian Testing so the package names will likely change on a different distribution. You don't have to use a chroot to do this but I prefer not to install lots of development packages on the system proper.

First off I've set up a new chroot with debootstrap:

mkdir mychroot
debootstrap --arch amd64 --variant minbase sid mychroot/ http://deb.debian.org/debian/

Once that's done we can chroot into it and start downloading some packages:

sudo chroot mychroot/
apt install build-essential git cmake cmake-curses-gui libopenal-dev libsdl1.2-dev libavcodec-dev libavformat-dev libavdevice-dev libavfilter-dev libavresample-dev libswscale-dev

cmake-curses-gui is optional; I find it's an easy way of altering cmake build options after using cmake.

Clone the repository somewhere:
git clone https://github.com/neuromancer/avp

Change into the cloned directory:
cd avp

Make a build directory and change into it:
mkdir build; cd build

Configure the project with cmake:
cmake ..

Optionally use the cmake gui to change build options; there's not a lot to alter - it already picks sensible defaults besides SDL2 is completely busted:
ccmake .

Compile:
make { or do make -j4 to use four cpu cores }

Even on my old Phenom II 955 the code should compiles very quickly.
Now you need the game data. I use innoextract with GOG's installer:
innoextract -d output setup_avp_classic_20160330_\(2149\).exe

Rename all the files/folders to lower case with the exception of the FMV folder. The final thing should look like this:
https://pastebin.com/Wnmc24nT

You'll need a few packages installed to play the game too i.e: libopenal, libsdl1.2, etc.
If you've already got steam installed you likely have a lot of them already.

To start the game in fullscreen mode use:
./avp -f

alien movement code

Can tell me whose are the functions to the alien movement controller?
Thank you!

segfaults on start - probably umlauts related

the game segfaults with german language with

workarounds the problem and the game starts fine (doesn't seem to be missing anthing important, but some words are missing umlauts as well)

can't build on fedora

Fedora 29
cmake 3.12.1

cmake runs fine with cmake -DCMAKE_BUILD_TYPE=Release -DAVP_BUILD_TYPE=DESKTOP .. but then when I run make it has an issue with the include for libraries that are part of ffmpeg:

$ make
Scanning dependencies of target avp

make: *** [Makefile:84: all] Error 2

but I have them on my system under /usr/include/ffmpeg/

MacOS support?

I got this compiled under MacOS Big Sur but couldn't get it to run. Build process was

brew install sdl
brew install sdl2
brew install ffmpeg
brew install cmake
mkdir build
cd build
cmake ..
make

but then got the following when trying to run avp:

Unable to obtain graphics context for NSWindow (Mojave behavior)

I then tried to build with SDL2:

cmake -DSDL_TYPE=SDL2 ..
make

But when running it's very clean the SDL2 port is not close to be finished as the game window doesn't start and only debug output is produced:

Is anyone still working on the SDL2 port or know any other way to get the game going on newer MacOS versions?

Failed to compile with GCC 10

$ gcc --version
gcc (GCC) 10.2.1 20200723 (Red Hat 10.2.1-1)

$ make -j128
/usr/bin/ld: CMakeFiles/avp.dir/src/opengl.c.o:(.bss+0x1703c): multiple definition of `WaterFallBase'; CMakeFiles/avp.dir/src/stubs.c.o:(.bss+0x10): first defined here
collect2: error: ld returned 1 exit status

GCC 10 now enforces:

GCC now defaults to -fno-common. As a result, global variable accesses are more efficient on various targets. In C, global variables with multiple tentative definitions now result in linker errors. With -fcommon such definitions are silently merged during linking.

Unable to configure keys

Hi,

I managed to compile it and get it up and running on Linux, using the data files from the GOG release.
Everything appears to work fine, except that I'm unable to configure any keys.

As soon as I select a control I want to modify (by pressing ENTER), the bound key is cleared and 'confirmed', leaving me unable to specify the key I want to use. The default controls are unworkable for me and AFAIK the controls are stored in a binary format, so I can't edit them there either.

Is this a known issue, and can I fix it?

Regards
