docker (missing libpng)

Hi, I'm using walkero dockers

walkero/amigagccondocker os4-gcc11-afxgroup 0fa2e72d58b1 10 months ago 4.61GB
walkero/amigagccondocker os4-gcc11-adtools 214178218446 10 months ago 3.36GB

when trying to crosscomìile vba emulator I get:

alas I just know minimal usage of dockers:
How can I "install" libpng?
Or do I need add extra parameters to ./configure to search through my "own" directory with such (missing) dependencies?

Re: docker (missing libpng)

The docker containers are like linux installations in any computer. To install that library you have to get into the container and go to the SDK path /local/newlib and add the files you need.

The way to do it depends on how you run the docker containers. If you tell me how you execute them, I could help you do that installation.

Another way would be to extend the docker image with your changes by creating your own images.

Re: docker (missing libpng)

ok, here is how I launch your image:

sudo docker run -it --rm --name gcc11-ppc -v ${PWD}:/work -w /work walkero/amigagccondocker:os4-gcc11-adtools /bin/bash

Re: docker (missing libpng)

So, based on the way you run it, you create the docker container and get inside it, by running bash. If you do a
printenv
there should be an ENV variable named SDK_PATH or something like that, pointing to the SDK in the disk. You need to go in there and under local/newlib the library you want.
There is curl, wget to download it inside the container and also you have mc to do file manipulation.

Have in mind though, that when you exit the container, this is destroyed, which means you need to install that library every time you want to use it. To avoid that remove the --rm from the command you use when you run the docker container.

Re: docker (missing libpng)

ok thx so will remove --rm option.

BTW when linking with existing libpng16 on such dokcer, then in amigaos4 I get:
#VisualBoyAdvance --help
assertion "PNG16Base != NULL" failed: file "static/autoinit_png16_base.c", line 48

Building/linking with the one I have/use in my amigaos4 SDK then no problem:
#VisualBoyAdvance --help
VisualBoyAdvance [option ...] file

Options:
-1, --video-1x 1x
-2, --video-2x 2x
-3, --video-3x 3x

Re: docker (missing libpng)

You don't actually need to have the library installed into the SDK. You could have your own third-party subdirectory, and use GCC's -I and -L command line options to tell GCC where to find the header and library files.

I've done this with ZitaFTP server, so that it compiles out-of-the-box, without needing to install dependency files into the SDK on every machine.

Re: docker (missing libpng)

@jabirulo
Today I uploaded a new version of my docker containers with gcc11. From now on, they will have their own versions, starting from 2.0.0, so that people can use the version that works better for them.

These new docker image includes ppc-amigaos-gcc-11, which supports newlib, clib2 and clib4, with plenty of libraries already installed, including the libpng16

You can try it by pulling the image
walkero/amigagccondocker:os4-gcc11-2.0.0
or
walkero/amigagccondocker:os4-gcc11
which will be used as the latest image

If you try it, please let me know how it works with your projects. Have in mind that it worked fine with a few of my projects, but it is not extensively tested yet.

Re: docker (missing libpng)

using your latest docker image above.
Still getting same issue when building ¿:-/
Just changing/copying libpng16.a from my aos4 system solves it:

...
-rwxr--r-- 1 amidev amidev 1275458 Jul  9 11:52 /opt/ppc-amigaos/ppc-amigaos/SDK
/local/newlib/lib/libpng16.a*
-rw-r--r-- 1 amidev amidev  191856 Jul 11 22:19 /opt/ppc-amigaos/ppc-amigaos/SDK
/local/newlib/lib/libpng16.a.BAK
-rw-r--r-- 1 amidev amidev     879 Jul 11 22:19 /opt/ppc-amigaos/ppc-amigaos/SDK
/local/newlib/lib/libpng16.la
lrwxrwxrwx 1 amidev amidev      60 Jul 11 22:19 /opt/ppc-amigaos/ppc-amigaos/SDK
/local/newlib/lib/libpng.a -> /opt/ppc-amigaos/ppc-amigaos/SDK/local/newlib/lib/
libpng16.a*
...

The original (.BAK) is 191 856 bytes while the one I have/use 1 275 458
When using/building with .BAK I get on amigaos4 shell/CLI:
#VisualBoyAdvance
assertion "PNG16Base != NULL" failed: file "static/autoinit_png16_base.c", line 48

With the 1.2MB png16.a it works fine.

EDIT1: trying to build another tiny game that uses png and nop problem ¿:-/
no idea then what VBA makefile does (or does not) that executable fails with above issue.

EDIT2; I just change/use the latest libpng (http://www.os4depot.net/?function=showfile&file=development/library/graphics/libpng.lha) instead the one from the docker image (os4-gcc11) has.

Re: docker (missing libpng)

@jabirulo
Thank you so much for testing it. The libpng16 I use is from
https://github.com/salass00/png16_lib

If you had issues with it, as you described here, it would make sense to file an issue at that repo.

Meanwhile, I will change the docker image to take the latest from the OS4Depot as you did.

Re: docker (missing libpng)

thx, done.
https://github.com/salass00/png16_lib/issues/2

EDIT: and seems I forgot that I needed to install the png16.library in LIBS: on my AmigaOS4 system.

EDIT2: build again VBA with docker image (and its libpng16.a 1.6.38) and now with png16.library on my aos4 LIBS: no problems, THX

Re: docker (missing libpng)

So the library from salass is working fine, right?
If yes, I will leave the docker image as it is, and if someone want to use a different version, they can override.

Re: docker (missing libpng)

yes works ok, but it needs png16.library, so you need to include it somewhere so it can be "installed" in amigaos4.
Like is for clib4.library (...SDK/clib4)
