Eagle 5.12 Linux on Ubuntu Saucy 64bit?

amigabill

I used to be able to use Eagle 5.x on my 64bit Linux. I'm now having problems with it.

 

I suspect that the new way they deal with 32bit compatibility may be an issue. I have libpng installed, but Eagle 5.12 cannot find it.

 

eagle

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

 

 

ls /usr/lib/libpng*

ls: cannot access /usr/lib/libpng*: No such file or directory

 

 

ls -l /usr/lib/x86_64-linux-gnu/libpng*

-rw-r--r-- 1 root root 245538 Aug 22  2013 /usr/lib/x86_64-linux-gnu/libpng12.a

lrwxrwxrwx 1 root root     13 Aug 22  2013 /usr/lib/x86_64-linux-gnu/libpng12.so -> libpng12.so.0

lrwxrwxrwx 1 root root     35 Aug 22  2013 /usr/lib/x86_64-linux-gnu/libpng12.so.0 -> /lib/x86_64-linux-gnu/libpng12.so.0

lrwxrwxrwx 1 root root     10 Aug 22  2013 /usr/lib/x86_64-linux-gnu/libpng.a -> libpng12.a

lrwxrwxrwx 1 root root     11 Aug 22  2013 /usr/lib/x86_64-linux-gnu/libpng.so -> libpng12.so

 

 

Since we no longer have ia32 package, how else can we solve this?

 

Now, I was able to get Eagle 6.5.0 to work. Ubuntu has a package for Eagle 6.4.0, which I installed to get dependencies, then removed, keeping those dependencies, and tried my 6.5.0 install, which did come up. But there are occasions where I want 5.x, not 6.x. And I had previously been able to use both versions of Eagle without problem.

 

 

Before installing the Ubuntu package for Eagle 6.4.0, the lack of dependencies gave me a So such File or Directory error, for both 5.12 and 6.5 versions of Eagle. So the dependencies did make a difference for 5.12 as well, but there's still something not right.

 

I had updated my Kubuntu to Saucy a while back, but have been distracted with various things and have only now tried to load up Eagle since Summer 2013 sometime.

 

I tried to make a link to pick up the "multi-arch" style of things, but did not work, giving a wrong ELF type error

 

cd /usr/lib

sudo ln -s  x86_64-linux-gnu/libpng12.so.0 libpng12.so.0

eagle

eagle: error while loading shared libraries: libpng12.so.0: wrong ELF class: ELFCLASS64

 

So I don't understand how multiarch is supposed to work, or what the difference is between 5.12 and 6.5 about this.

 

I use Environment modules tool to select which version of Eagle is in my path, which has worked for me for several years like this:

 

module avail pcb

 

------------------------------- /opt/Modules/modulefiles -------------------------------

pcb-tools/eagle/5.10.0         pcb-tools/gerbv/2.6.0

pcb-tools/eagle/5.11.0         pcb-tools/kicad/bzr2932-stable

pcb-tools/eagle/5.12.0         pcb-tools/kicad/bzr3044-stable

pcb-tools/eagle/6.5.0          pcb-tools/kicad/bzr3256-stable

 

module load pcb-tools/eagle/6.5.0

which eagle

/opt/pcb/eagle/6.5.0/bin/eagle

module unload pcb-tools/eagle/6.5.0

which eagle

(nothing found)

module load pcb-tools/eagle/5.12.0

which eagle

/opt/pcb/eagle/5.12.0/bin/eagle

    Do you? The right one?

    OK, so the answer is no, you don't have libpng for 32-bit applications

    at all.

     

    ls -l /usr/lib/x86_64-linux-gnu/libpng*

     

    This directory is irrelevant - it's the 64-bit libraries for native

    64-bit applications.

     

     

    Since we no longer have ia32 package, how else can we solve this?

     

    Use a better Linux?

     

    Or ask on an Ubuntu forum about reinstating libpng12 for 32-bit

     

     

    Now, I was able to get Eagle 6.5.0 to work. Ubuntu has a package for

    Eagle 6.4.0, which I installed to get dependencies, then removed,

    keeping those dependencies, and tried my 6.5.0 install, which did come

    up. But there are occasions where I want 5.x, not 6.x. And I had

    previously been able to use both versions of Eagle without problem.

     

    You've done an upgrade in which APT has decided there are no longer any

    users of libpng12 (32-bit) and thus has removed it.

     

    I had updated my Kubuntu to Saucy a while back, but have been distracted

    with various things and have only now tried to load up Eagle since

    Summer 2013 sometime.

     

    Yes, that's probably what did it.

     

    I tried to make a link to pick up the "multi-arch" style of things, but

    did not work, giving a wrong ELF type error

     

    cd /usr/lib

    sudo ln -s  x86_64-linux-gnu/libpng12.so.0 libpng12.so.0

     

    No, that won't work. There's a reason the 32-bit libraries and 64-bit

    libraries are kept separate - they're NOT THE SAME, nor even compatible.

     

    So I don't understand how multiarch is supposed to work, or what the

    difference is between 5.12 and 6.5 about this.

     

    The difference is that 6.x doesn't use the libpng12 library any more.

    LOL!  I'm a confirmed RedHat Enterprise/CentOS guy myself, even though some would argue that apt is better than yum.  I've found apt to be too smart for its own good sometimes...

     

    My own question is why doesn't Cadsoft just compile a 64 bit version of EAGLE...?
