When you try to install Eagle 6.1.0 on Ubuntu 11.10, you will probably get an error message stating that libpng14 is missing. Here is how you could sort that out.

Prep Ubuntu for 32 bit compilation

Code: Select all

sudo apt-get install build-essential lib32z1-dev g++-multilib gcc-multilib ia32-libs libssl1.0.0 libssl1.0.0:i386 libjpeg8 libjpeg8:i386

Download libpng14 from the following link

Code: Select all

http://sourceforge.net/projects/libpng/files/libpng14/1.4.8/libpng-1.4.8.tar.xz/download

Decompress it by using following command.
Code: Select all
```
tar xvf libpng-1.4.8*
```
Now change the folder and compile the source as below.
Code: Select all
```
cd libpng-*
./configure CFLAGS=-m32 --prefix=/
make check
sudo make install
```
Note: For 32-bit Linux, remove "CFLAGS=-m32" and just use this line instead:
Code: Select all
```
./configure  --prefix=/
```
Now install Eagle.
Code: Select all
```
chmod a+x eagle-lin*
sudo ./eagle-lin*
```
