| Linker doesn't find Oklab & RGB Linear conversion functions |

I know I'm the only one using Pascal here but I'll ask anyway: Trying to port ex_color_gradient to Pascal the linker can't find Oklab nor linear functions (i.e. al_color_rgb_to_oklab and such). The weird thing is that C version compiles and runs without any problem. Also the Pascal linker is able to find CIELab and HVS Of course, I've check my Allegro installation (version 5.2.8) and it is correct. Also I've read the sources to see if these functions have any sort of alias or something weird with parameters but everything looks right. Any idea about what would be happening? ----------------- |

I don't think that's the answer. As I've said other color functions work (HSV and the CIElab). Maybe there's something in the functions signatures that I didn't care of. ----------------- |

Well, you know. If the libraries you're linking to don't have them, they're not there. They were just added in 5.2.8, so your libs are either old, you've got the wrong headers, or something else.

I'm thinking, maybe there are some part of the add-on that is in the static part of the library (the .a file?). If so, that is the problem as Free Pascal and Delphi just load the DLL/so file. ----------------- |

Are they inline? I still think you're linking to an old library. My Website! | EAGLE GUI Library Demos | My Deviant Art Gallery | Spiraloid Preview | A4 FontMaker | Skyline! (Missile Defense) Eagle and Allegro 5 binaries | Older Allegro 4 and 5 binaries | Allegro 5 compile guide |

Edgar Reynaldo said: Are they inline? I still think you're linking to an old library. I'm using 5.2.8.0. Isn't it the latest? Anyway I'm having issues with this version that I hadn't in previous versions (for example: multithreading API stopped to work, as well as most of the native dialog stuff, and reading events using al_wait_for_events seems to be laggy while using al_is_event_queue_empty+al_get_next_event works way better). As said, using Allegro 5.2.8.0 installed from sources on Debian 11. ----------------- |

Have you had any other versions installed before this? I think your linker is looking in the wrong place. Did you install to /usr or /usr/local ?

I had older versions but they're not installed currently. I've installed in /usr/local/lib (I didn't change CMAKE+make nor use any command option). I've revised /usr/local/lib and there's no reference to any other Allegro version. ----------------- |

Did you use your package manager to install allegro? That would leave a version in /usr . My Website! | EAGLE GUI Library Demos | My Deviant Art Gallery | Spiraloid Preview | A4 FontMaker | Skyline!

No, I didn't use the package manager. I downloaded the sources, executed the CMAKE configuration and make install. /usr/lib* directories don't have any Allegro file. ----------------- |

Alright, well you're exhausting my ideas, but I'm not out yet. First, in C, a function that isn't declared is by default a void function. If you didn't include the color addon header, they won't be declared, and when you use them, they will be undefined, because the linker is looking for different functions. Or, you have headers older than 5.2.8 on your system. If you ever installed from source, they may be in /usr/local/include. Finally, are you telling your Pascal linker about the color addon? You still have to link it. Also, did cmake tell you if it was building the color addon or not?

The original Allegro example works so yes, it had build the color addon. About linking, yes: Pascal links the addon as other functions of the addon work. I'm asking to Free Pascal people. Maybe they know something. [edit] You were right: there were some old stuff that conflicted, so I had to uninstall stuff, reinstall other stuff, recompile Allegro and bam! it now compiles. Maybe that fixes the other issues I have. Thankyou very much. ----------------- |
