Retropie-setup: Packaging Conflict (ubuntu 16)

[xrobau]

Emulation Station requires 'libfreetype6-dev', which requires 'libpng-dev'.

'libpng-dev' is libpng1.2, which doesn't have 'png_set_longjmp_fn' which was introduced in 1.3

GLupeN64 requires this

/GLideN64/src/GLideNHQ/TxImage.o: In function `TxImage::getPNGInfo(_IO_FILE*, png_struct_def**, png_info_def**)':
TxImage.cpp:(.text+0xd9): undefined reference to `png_set_longjmp_fn'
./GLideN64/src/GLideNHQ/TxImage.o: In function `TxImage::writePNG(unsigned char*, _IO_FILE*, int, int, int, unsigned short, unsigned char*)':

which Ubuntu 16 ? ubuntu 16.10 is not yet supported (and there are known issues). Also please give details of version of retropie-setup etc. Which platform ?

[xrobau]

Sorry, yes, 16.04.01.

I think you have a problem with the dependencies on your system - libfreetype6-dev / libpng-dev should install fine. Aptitude might give you more information.

[joolswills]

ES and lr-glupen64plus build / run fine on my ubuntu 16.10 for example.

[xrobau]

Ubuntu 16.10 has libpng-dev from libpng16. Ubuntu 16.04 has libpng-dev from libpng12. You need to install 'libpng16-dev' to get png_set_longjmp_fn in 16.04. But if you install that, you can't install libfreetype6-dev, which is required by emulation station.

[joolswills]

I'm sure I have built it fine on Ubuntu 16.04 before. If glupen64 has changed some requirements then you should report it to them - I don't think libpng16 should be needed (builds fine on Debian jessie which only has libpng1.2)

[xrobau]

I dunno what to say man. It's broken. I'm an open source developer, so I understand you wanting to hand it upstream as a problem, but that's not really something I can do.

If I hand it upstream, they're going to want to know what, how, and where. But, your build script seems to delete everything, and just leaves me a gzipped logfile.

For me to take this upstream, I'm going to need to pull apart your build script to figure out what the problem is, DUPLICATE that it is a problem with them (and not something you're passing to configure), and then liaise with them to get it fixed.

I've told you what the problem is, and explained why it's a problem. The sucky solution would be to build ES first, then remove freetype6-dev and libpng and libpng-dev and THEN install libpng16 and libpng16-dev, and then continue building.

The _root_ cause is a packaging issue in 16.04 - libpng16-dev should be saying that it provides the package libpng-dev, and it's not. As 16.04 is a LTS release, it's going to be almost impossible for them to change that, and it PROBABLY is deliberate.

So, where does this leave us? Pretty much stuck. I suggest you close it as 'wontfix' and mark 16.,04 as known broken, unless someone else who knows the installer wants to take the time to pull it apart and either report it upstream, or fix the issues.

[joolswills]

The buildscript only deletes everything if the build succeeds - the lr-glupen64 should stop on an error and the log should contain the build errors. (and the source will be in RetroPie-Setup/tmp/build/lr-glupen64)

you can build from commandline with sudo ./retropie_packages.sh lr-glupen64

but ok - I'll do it for you.

[joolswills]

Sorry - without the plus. I amended my post. run ./retropie_packages.sh without parameters for more info.

[joolswills]

I'm bisecting the issue now - looks to be something introduced with some recent commits.

[joolswills]

It's broken on Raspbian too now since the change - https://github.com/loganmc10/GLupeN64/issues/97

[joolswills]

fixed upstream. You will need to remove the libpng16-dev and put libpng12-dev back.

[xrobau]

Still building (did a complete clean checkout), but seems to be fixed. Will update ticket when it's completed everything. Thanks!
