Does anyone know how to fix this? I've tried updating /etc/ld.so.conf to include the library file location but it didn't change anything. I also put the location in the IDE which is how I normally include library files.

In any case I'm not having any luck. I installed allegro 4.4 is it possible its looking at the Allegro 5 file of the same name and balking at it?

Thanks

Thanks Edgar. I'm still confused however. (See the included picture) The liballeg.so file is available (in red) . This is the setup I had in the IDE from my previous computer. It compiled fine then. However I was static linking then and this time, I removed the XXXXXX.a file from the list along with commenting out the STATICLINK lines in the program.

In any case, I tried liballegro.so file,(in yellow). It didn't change anything. Sounds like I have a typo and I'm too close to see it. Let me know what you think. Thanks.

Ok I've tried compiling using a different IDE (Dev-C) and out of Windows. I'm not getting the usr/bin error of course but I'm getting a pc.h file not found. It's not on my system. It is being called by aldjgpp.h. Does any one know why I wouldn't have this file as part of the A4 package? Thanks.

So pc.h isn't an Allegro file?

Daniel, I’m using Windows on the same computer with DEV-C / MingW I used when I originally wrote and compiled my game. The game was done a couple years ago. Over time I started using Eclipse and MingW. I wanted to double check something concerning A4 Fullscreen Vs Windowed. I tried to recompile the game using Kubuntu & Eclipse. I got the /usr/bin/ld: cannot find -lalleg.so: No such file or directory error.

I decided to compile on the Win computer, Win 10 & Eclipse / MingW. I started getting the pc.h error. I went back to Dev-C/MingW, the original setup I used to create the Win version of the game but got the same pc.h error.

I’m starting to think the issue is with my A4 installation. My Linux computer is new so it didn’t have A4 on it. I had to reinstall. Long story but Win computer no longer had A4 available either. I downloaded the A4 7Z file (for Win)and extracted it. I placed the folder in the appropriate location to be in the path. I did the same for Linux though using Linux compressed file.
It just occurred to me, I didn’t actually “build” anything or run a setup. I was thinking last time (2+ years ago) I didn’t build anything either. Maybe I had the binaries back then. What do you all think? Lack of build/install?

Thanks Daniel. Yeah, I am all over the map. In short I’ve always use Eclipse with Linux. For Windows, I’m using Portable Apps from a flash drive. I started a couple of years ago with Dev until I got Eclipse to work. At that time I was using Eclipse with both Win and Linux. Recently I tried to recompile an old game of mine. On Linux I got the “ld can’t find file” error. So I tried Win (with Eclipse) and got the pc.h file issue. I went to my original Win / Dev setup which the game was written & compiled from and got the same error.

What is odd, I’m not using any weird libs or header files. Outside of some games specific headers. I’m only using allegro.h and liballeg (or alleg). The pc.h header file is called from the allegro.h file. Also I'm not intentionally using any DJGPP configuration. (Win)

Even more strange, (Linux) running ld -L/usr/lib/x86_64-linux-gnu/ -lalleg.so --verbose sees the file and several associated files.

In any case I’ll stumble across the answer eventually for one or the other.

Yeah, it sounds like you're trying to include headers from the source distribution, which won't work because they haven't been configured by cmake.

What version of gcc are you using? Type gcc -v on Win and Linux and figure out the compiler version. This then has to match your binary distribution wherever you got it from.

Yes, I do have A443 binaries for Windows if you're interested. They use the gcc 8.1 posix seh MinGW64 compiler. I can give you links to both if you choose.

How did you install allegro on linux? Using your package manager? Or compiling from source?

We'll straighten this out, don't worry.

First, liballeg.so is static on linux and windows. You generally don't compile statically on Linux. Use liballeg44.so instread.

As for windows, which zip file for allegro did you get from where?

All, sorry for the wild goose chase. I found my final code for the game I wrote. I started a new program in the IDE and copy paste the text from the source code into the IDE files of the same name. I was able to compile and run it from Linux no problem. Basically, just a fresh start from scratch solved the Linux problem.

I quickly did the same thing from Windows but still get the "can't find pc.h" error. I believe I need the binaries of Allegro to fix this issue. I'll work on get them.

Thanks for all the help.

My Allegro 443 binaries are on Bitbucket. And you can get the compiler I used on Sourceforge. Links below.
