New issue 511 by httpw...@gmail.com: Compilation fails on Ubuntu 16.04 xenial
https://bugs.chromium.org/p/webp/issues/detail?id=511

What steps will reproduce the problem?

1. Have a fresh installation of Ubuntu 16.04

2. Install dependancies
apt-get install libjpeg-dev libpng-dev libtiff-dev libgif-dev

3. Try to compile and install libwebp on the system
# wget https://storage.googleapis.com/downloads.webmproject.org/releases/webp/libwebp-1.2.0.tar.gz
# tar -xvf libwebp-1.2.0.tar.gz
# cd libwebp-1.2.0

----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the 'LD_RUN_PATH' environment variable
during linking
- use the '-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the 'LD_RUN_PATH' environment variable
during linking
- use the '-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
PRODUCT VERSION: 1.2.0

OPERATING SYSTEM:
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.7 LTS
Release: 16.04
Codename: xenial


Please provide any additional information below.
I tried your precompiled version but it fails to run on my system as you can see below:

# bin/cwebp
bin/cwebp: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by bin/cwebp)


Please help, I would love to use your library to optimize my websites pictures.

Thanks a lot for your time & help

Best regards

Comment #1 on issue 511 by jz...@chromium.org: Compilation fails on Ubuntu 16.04 xenial
https://bugs.chromium.org/p/webp/issues/detail?id=511#c1

Thanks for the report. Unfortunately this slipped into the release. I fixed this in the main branch and the release branch, but I didn't make a 1.2.1 release. You should be able to patch the change in to fix the issue:
