QUESTION
I'm trying to include allegro5 in a cmake project.
...ANSWER
Answered 2021-Jun-06 at 21:22You almost have it except for a misunderstanding of pkg_check_modules()
.
The first argument to pkg_check_modules()
is a literal prefix that you choose. This will be the prefix to all the variables that pkg_check_modules()
sets. If you had chosen "foo", the variables that would have been set would be foo_LIBRARIES
, foo_INCLUDE_DIRS
, foo_CFLAGS
, etc.
You chose the prefix "allegro-5", but in subsequent commands you're trying to use the varibales ALLEGRO_LIBRARIES
and ALLEGRO5_INCLUDE_DIRS
. These variables aren't set, because the variables that you actually want are allegro-5_LIBRARIES
and allegro-5_INCLUDE_DIRS
. Change those 3 three commands to:
QUESTION
I created a C++ game that uses images from a folder in the same parent directory.
...ANSWER
Answered 2021-Jun-02 at 09:54The reason why this does not work is that your code gets compiled and is then placed inside the catkin_ws/devel/lib/
folder (lib
not include
!). Then when you launch the code it will look only in paths relative to the executable. This means you would actually have to place it inside the catkin_ws/devel/lib/
folder. The problem with that is though that as soon as you clean the workspace all of these directories will be deleted and you would have to re-copy all the files to it after each catkin clean
.
For this purpose the ROS C++ API has though functions that allow you to browse the folder of a given package inside the catkin_ws/src
folder or display all available packages when including the header file ros/package.h

QUESTION
What is the best practice for mounting an S3 container inside a docker image that will be using as a ClearML agent? I can think of 3 solutions, but have been unable to get any to work currently:
- Use prefabbed configuration in ClearML, specifically CLEARML_AGENT_K8S_HOST_MOUNT. For this to work, the S3 bucket would be mounted separately on the host using rclone and then remapped into docker. This appears to only apply to Kubernetes and not Docker - and therefore would not work.
- Mount using s3fuse as specified here. The issue is will it work with the S3 bucket secret stored in ClearML browser sessions? This would also appear to be complicated and require custom docker images, not to mention running the docker image as --privileged or similar.
- Pass arguments to docker using "docker_args and docker_bash_setup_script arguments to Task.create()" as specified in the 1.0 release notes. This would be similar to (1), but the arguments would be for bind-mounting the volume. I do not see much documentation or examples on how this new feature may be used for this end.

Answered 2021-May-12 at 04:32i would recommend you to check out the Storage gateway S3 behind the gateway you can use the NFS, EFS or S3 bucket.
Read more at : https://aws.amazon.com/storagegateway/?whats-new-cards.sort-by=item.additionalFields.postDateTime&whats-new-cards.sort-order=desc
There are multiple ways you can do this. You can also use the CSI driver to connect the S3 also.
https://github.com/ctrox/csi-s3
rclone is nice option if you can use it, which will sync data to the POD host system in that if large files are there it might take time due to file size and network latecy.
Personal suggestion S3 is object storage so if you are looking forward to do file operations like writing the file or zip file it might take time to do operation based on my personal experience.
Remember that s3 is NOT a file system, but an object store - while mounting IS an incredibly useful capability - I wouldn't leverage anything more than file read or create - don't try to append a file, don't try to use file system trickery
If that the case I would recommend using the NFS or SSD to the container.
while if we look for s3fs-fuse it has own benefit of multipart upload and MD5 & local caching etc.
The easiest way you can write your own script which will sync to the local directory with the directory of S3 bucket over HTTP or else Storage gateway S3 is good option.
Amazon S3 File Gateway provides a seamless way to connect to the cloud in order to store application data files and backup images as durable objects in Amazon S3 cloud storage. Amazon S3 File Gateway offers SMB or NFS-based access to data in Amazon S3 with local caching.
QUESTION
I'm making a project in C, with Allegro 5 library. I got some skins for my snake, but I want to make something better, like user-styled skin. And I think the best way will be:
- Make a white snake as that in image in post.
- Color white to another color.
And now I'm looking for Allegro function to make it fast and easy. What I got:
- al_tinted_bitmap - it's also coloring eyes and tongue
- al_get_pixel, put_pixel - but I must give x/y of white color, and that's really hard with bitmap like that (i mean... with square it will be easier)
So I think, I need a function or something like "get_pixel", but with specifying rgb(R, G, B), not X/Y. What's should I try used to make it functional like that?
...ANSWER
Answered 2021-Apr-29 at 14:23This question led to a nice discussion on the allegro forums Credits to Dizzy Egg for working out this example in full detail. I'll summarize the answer here for future reference.
A solution with al_tinted_bitmap is definitely possible, but I'd choose the get_pixel / put_pixel approach as you have a bit more control. It's not hard to replace pixels of one color with pixels of another color. Just loop over each pixel in the bitmap and do this:

QUESTION
So I am creating a C++ program using the allegro version 4.4.2 library and I need to be able to produce an executable package which I can submit to a course instructor and have run on his computer without issues. I am developing the program using DevC++. If I am understanding this correctly so far, I need to link to a static library for allegro and then the executable should include the library info and thus the library itself is not necessary to have included in the executable package. I have also seen some recommendations regarding third party tools that produce executable packages, but these seem to be more general (not necessarily allegro compatible?) and I am hoping to avoid downloading more third party software.
I have tried linking to the static library liballegro-4.4.2-monolith-static-mt.a but for some reason when I do this I get a whole slew of undefined reference compile time errors. I have read that it is necessary to have #define ALLEGRO_STATICLINK included in the project, I have this statement at the top of my main source file but I am not sure if I am meant to define this somewhere in the project options instead?
Any guidance or link to resources which will help me solve my problem would be extremely appreciated! I am just getting into the meat of programming with C++ beginning to learn object oriented programming methods, I still occasionally struggle with the basics so thank you in advance for your help!
Backstory (if interested/relevant?): I am taking a Game AI programming course for which we need to create some example programs to demonstrate AI algorithms. The course specifies Java but I am most familiar with C++ and the course instructor says this is fine but I must be able to submit an executable to him which he can just run on his computer without issues. To best achieve what the course asks I feel the allegro library (which I already have installed) will be of great help, mostly for drawing graphics to the screen and such.
...ANSWER
Answered 2021-Feb-27 at 02:25So I just ended up using a dynamically linked version of my program and including the appropriate .dll files which turned out to be a lot less work than I thought it would be.
Basically I just had to ensure the allegro-4.4.2-md.dll from the bin folder was included in the folder with the executable. I then sent off the package (the .exe compiled file and the needed supporting files such as bitmaps sound files etc) to a few friends and had them try to run it. They then gave me the warnings from their computers along the lines of "Test.exe cannot be run ****.dll cannot be found".
I searched the exact names of the dll files they were receiving warnings for in the folder with my game and voila it now seems to execute on whatever PC it is sent to.
QUESTION
When running the following C file, copying the character to fgetc
to my tmp pointer results in unknown characters being copied over for some reason. The characters received from fgetc()
are the expected characters. However, for some reason when assigning this character to my tmp pointer unknown characters get copied over.
I've tried looking for the reason why online, but haven't found any luck. From what I have read it could be something to do with UTF-8 and ASCII issues. However, I'm not sure about the fix. I'm a relatively new C programmer and still new to memory management.

...ANSWER
Answered 2021-Feb-06 at 00:08When you write a loop that updates various things each time through, like you do with tmpSize
in your loop here, it's important to have a handle on what the theoretical computer science types call your "loop invariants". That is, what is it that's true each time through the loop? It's important not only to maintain your loop invariants properly, but also to pick your loop invariants so that they're easy to maintain, and easy for a later reader to understand and to verify.
Since tmpSize
starts out as 1, I'm guessing your loop invariant is trying to be, "tmpSize
is always one more than the size of the string I've read so far". A reason for picking that slightly-strange loop invariant is, of course, that you'll need that extra byte for the terminating \0
. The other clue is that you're setting tmp[tmpSize-1] = c;
.
But here's the first problem. When we exit the loop, and if tmpSize
is still one more than the size of the string you've read so far, let's see what happens. Suppose we read three characters. So tmpSize
should be 4. So we'll set tmp[4] = 0;
. But wait! Remember, arrays in C are 0-based. So the three characters we read are in tmp[0]
, tmp[1]
, and tmp[2]
, and we want the terminating \0
character to go into tmp[3]
, not tmp[4]
. Something is wrong.
But actually, it's worse than that. I wasn't at all sure I understood the loop invariant, so I cheated, and inserted a few debugging printouts. Right before the realloc
call, I added
