Xuggler compilation is failing.

Question

I DID NOT FIND THE PRECOMPILED BINARIES FOR WINDOWS OR LINUX PLATFORM, AND I am trying to build the Xuggler code base cloned from the github. I am following the steps given in the link: http://www.xuggle.com/xuggler/build

I am facing a compilation error as below. Can someone please help me with what is missing? All the build environment prerequisite are taken care of.

CAN SOMEONE ALSO HELP WHERE TO FIND THE PRECOMPILED XUGGLER BINARIES FOR WINDOWS?

Answer 1

Folks,

So finally I was able to successfully build the Xuggler build. It was a compiler version issue. I had installed (by virtue of apt-get install build-essential) latest version of gcc (version 4.7), and it was throwing all the below errors.

I downgraded my system to version 4.4, and it worked. I could have chosen 4.6 or something else, but now I guess its not required.

/anil.

Answer 2

I've found another solution to fix this build fail:

[exec] cc1plus: all warnings being treated as errors

If you want to fix it independently from gcc version (you cannot choose gcc version in some linux distributions), go to the xuggle downloaded/extracted folder and use:

grep -rl "Werror" * | xargs sed -i 's/Werror/Wno-error/g'

This will force the compiler to consider warnings as warnings and not as errors, and the build will succeed.

---

Note: if you want to be sure that this command takes effect, before the command use:

grep -rl "Werror" * 

And after the command use:

grep -rl "Wno-error" * 

They should give you the same file-list.

Install GCC 4.4:

apt-get install gcc-4.4

Update symbolic links to use 4.4 (the arch-specific link will be different on 32-bit VM):

rm /usr/bin/gcc
ln -s /usr/bin/gcc-4.4 /usr/bin/gcc
rm /usr/bin/x86_64-linux-gnu-gcc
ln -s /usr/bin/x86_64-linux-gnu-gcc-4.4 /usr/bin/x86_64-linux-gnu-gcc

Install C++ (G++) 4.4:

apt-get install c++-4.4

Update symbolic links to use 4.4 (the arch-specific link will be different on 32-bit VM):

rm /usr/bin/cpp
ln -s /usr/bin/cpp-4.4 /usr/bin/cpp
rm /usr/bin/x86_64-linux-gnu-cpp
ln -s /usr/bin/x86_64-linux-gnu-cpp-4.4 /usr/bin/x86_64-linux-gnu-cpp
rm /usr/bin/g++
ln -s /usr/bin/g++-4.4 /usr/bin/g++
rm /usr/bin/x86_64-linux-gnu-g++
ln -s /usr/bin/x86_64-linux-gnu-g++-4.4 /usr/bin/x86_64-linux-gnu-g++

Verify default versions:

gcc --version
c++ --version
cpp --version

If c++ wouldnt be found install g++ 4.4

apt-get install g++-4.4

That works for me to build a LGPL linux jar on a Ubuntu 14.0.4 LTS 64

here is the full guide: https://docs.google.com/document/d/1mjlI2jAGKK3_W4KIBjpUfM3F_SJjUkZhQJuwtIBn_7I/pub

remember to install g++ if the build failed

//windows build - still doesnt work for me
