[SOLVED] Problems launching Quartus II

So, I've downloaded Quartus II web edition 13.0 (altera software) and installed it with no error messages.
When I tried running it I go this problem

sudo ./quartus
quartus: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory

I have installed libpng

sudo pacman -Syu libpng

and still got the same problem. I saw one thread online saying I should download multilib-devel, and so i did (link to the thread: https://bbs.archlinux.org/viewtopic.php?id=190304), but I am still getting the same error. What should I do?

Re: [SOLVED] Problems launching Quartus II

Why aren't you just installing quartus from the AUR?
https://aur.archlinux.org/packages/quartus-free/

Re: [SOLVED] Problems launching Quartus II

I'm not installing from the AUR because I need version 13.0, not 15

Re: [SOLVED] Problems launching Quartus II

Version 13.0 is also available from AUR: https://aur.archlinux.org/packages/quartus-free-130/
You could at least check the dependencies from the PKGBUILD for reference. Looks like you need libpng12 or lib32-libpng12 depending on your $CARCH.

Re: [SOLVED] Problems launching Quartus II

Well, that is exactly my problem. Where do I get libpng12? I did install libpng, is it not the same?

Re: [SOLVED] Problems launching Quartus II

Ok, so I actually do have libpng12.so.0 as shown in the code below.

locate libpng12.so                                          127 
/home/arthurgl/.local/share/Steam/ubuntu12_32/steam-runtime/amd64/lib/x86_64-linux-gnu/libpng12.so.0
/home/arthurgl/.local/share/Steam/ubuntu12_32/steam-runtime/amd64/lib/x86_64-linux-gnu/libpng12.so.0.46.0
/home/arthurgl/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu/libpng12.so.0

/home/arthurgl/src/libpng12/pkg/libpng12/usr/lib/libpng12.so.0.56.0
/home/arthurgl/src/libpng12/src/libpng-1.2.56/.libs/libpng12.so
/home/arthurgl/src/libpng12/src/libpng-1.2.56/.libs/libpng12.so.0
/home/arthurgl/src/libpng12/src/libpng-1.2.56/.libs/libpng12.so.0.56.0
/usr/lib/libpng12.so
/usr/lib/libpng12.so.0
/usr/lib/libpng12.so.0.56.0

What should I do then? Seen that Quartus II still won't launch, giving me the same error.

I did as you told me and I need the libpng12, not the one I was getting with pacman.
Now I've installed (via AUR) the libpng12 package, and it does appear on both /usr/lib and /lib/ directories, but I still get the same error, any advice on this problem?

Thanks in advance.

Re: [SOLVED] Problems launching Quartus II

Any advice?

1. Install software from the AUR instead of building it yourself. It's best practice and keeps the system cleaner and more maintainable.
--- If you need to install version 13 instead of version 16 then install the AUR package for version 13.

2. Read the documentation.
--- The PKGBUILD says what is required to build and run each piece of software in Arch.
--- The PKGBUILD for each of those things says what each of them need, etc.

https://aur.archlinux.org/cgit/aur.git/ … ee-130#n35

if [[ $CARCH = x86_64 ]]
then
   depends=('lib32-glibc' 'lib32-libxext' 'lib32-libx11' 
				    'lib32-libxau' 'lib32-libxdmcp' 'lib32-freetype2'
				    'lib32-fontconfig' 'lib32-expat' 'lib32-libpng12')
   optdepends=('lib32-gtk: For eclipse-nios2 support'
               'lib32-libxtst: For eclipse-nios2 support')
fi

Re: [SOLVED] Problems launching Quartus II

Nevermind, figured it out
Had to add the path of the shared library to the ld.so.conf file and the run sudo ldconfig.

Thank you for your replies guys.

PS: Thanks for your patience with a arch newbie ChickenMan, also, thanks for the tips you gave me!
