I am attempting to install emacs 25.1 on lubuntu 16.04, and having some trouble. After downloading and extracting the tar, I navigate to the emacs 25.1 directory then..
./configure
The configuration stops when I receive the message
configure: error: The following required libraries were not found:
libpng
Maybe some development libraries/packages are missing?
If you don't want to link with them give
--with-png=no
as options to configure
When I try sudo apt install libpng-dev
I get the message
Note, selecting 'libpng12-dev' instead of 'libpng-dev'
libpng12-dev is already the newest version (1.2.54-1ubuntu1).
0 upgraded, 0 newly installed, 0 to remove and 9 not upgraded.
I tried reinstalling libpng12-dev using the below string, which didn't help at all.
sudo apt-get install --reinstall libpng12-0=1.2.54-1ubuntu1
I'm stuck here, I've googled around for a while and can't find any solutions that have actually worked.
I have the same problem. After I checked the config.log
file, I found out that because I already installed Anaconda3 python
when gcc compile emacs it uses some libpng...
found in Anconda3 directory.
So I remove related Anaconda3 directory in PATH
, everything turns out right.
The wrong version:
configure:15301: result: -lz
configure:15407: checking for png
configure:15437: gcc -o conftest -g3 -O2 -I/etc/anaconda3/include/libpng16 conftest.c -lpng16 -lz -lm -lX11 >&5
/usr/bin/ld: cannot find -lpng16
The right version:
configure:15301: result: -lz
configure:15407: checking for png
configure:15437: gcc -o conftest -g3 -O2 -I/usr/include/libpng12 conftest.c -lpng12 -lz -lm -lX11 >&5
configure:15437: $? = 0
configure:15452: result: yes
Hope that would be helpful!
