Error on building ESDK 2016.11 on ubuntu 16.04 about epiphany-sdk HOT 2 CLOSED

I was stuck on this problem for 3 days. I was running Ubuntu 14.04 - which according to the documentation is an officially supported release. I think it's sad that developers haven't responded to this in 2 months. Here's how i resolved the issue:

Dependencies:

apt install build-essential git bison flex libgmp3-dev libncurses-dev libmpc-dev libmpfr-dev texinfo xzip lzip zip
apt install gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf
apt install guile-1.8

mkdir buildroot && cd buildroot
git clone --branch 2016.11 https://github.com/adapteva/epiphany-sdk.git sdk
./sdk/build-epiphany-sdk.sh -C -c arm-linux-gnueabihf

Problem 1:

Epiphany-SDK installer refuses to work on many Linux distros due to its age. However it will work on ubuntu 14.04.

Problem 2: (Linkage problems part 1)

This will fail with an error about not being able to find ./../zlib directory, but the command needs to be run anyway to create the directories.

Copy zlib-1.2.11.tar.gz into the ~/buildroot/builds/bd-x86_64-2016.11/ directory, extract it, rename the extracted directory to zlib/ and run ./configure, and make.

Comment out line 927 of build-toolchain.sh... the call to a rm -rf, which myopically deletes the directory even when there's no clean option given to the build-epiphany-sdk.sh script.

Then run:

./sdk/build-epiphany-sdk.sh -c arm-linux-gnueabihf

Do NOT use the capitol -C option the second time as it will delete the zlib you just made!! The lower case -c is fine however.

Copy the zlib directory into ~/buildroot/builds/bd-armv7l-2016.11. Make sure it's named zlib/ not zlib-1.2.... etc. Because bd-armv71-2016.11 needs it too.

Problem 3: (Linkage problems part 2)

Building the Epiphany-SDK will now fail with ~/buildroot/builds/bd-armv7l-2016.11/gas not recognising file type of libz.so

This is because this version of zlib needs to be cross compiled for ARM, so autotools cannot link it to the rest of the cross compiled binaries.

To fix this enter into the zlib in the bd-armv7l-2016.11 directory and run:

CC="arm-linux-gnueabihf-gcc" ./configure

This will tell configure to use an ARM compiler rather than the default x86 compiler.

Then run "make".

Resume with:

./sdk/build-epiphany-sdk.sh -c arm-linux-gnueabihf

Again do NOT use the capitol -C option, else this will delete the cross-compiled zlib.

Problem 4: (Missing eng.h header)

There is another problem:

fatal error: eng.h no such file or directory.
#include "eng.h"

in directory ~/buildroot/unisrc-2016.11/sim/epiphany/cpuall.h

being compiled from ~/buildroot/buildss/bd-armv7l-2016.11/sim

The eng.h exists in:

~/buildroot/gdb/sim/sh64/eng.h
~/buildroot/binutils/sim/sh64/eng.h
~/buildroot/unisrc-2016.11/sim/sh64/eng.h

These files are exactly the same. There are 2 other headers that are missing in that directory, you can fix them as follows:

cp ~/buildroot/gdb/sim/sh64/eng.h ~/buildroot/builds/bd-armv7l-2016.11/sim/epiphany/
cp ~/buildroot/gdb/sim/sh64/eng-compact.h ~/buildroot/builds/bd-armv7l-2016.11/sim/epiphany/
cp ~/buildroot/gdb/sim/sh64/eng-media.h ~/buildroot/builds/bd-armv7l-2016.11/sim/epiphany/

then rerun:

./sdk/build-epiphany-sdk.sh -c arm-linux-gnueabihf

Problem 5 (undocumented autotools dependencies in epiphany-libs):

autoreconf: not found

fixed by "apt install autoconf"

Reran:

./sdk/build-epiphany-sdk.sh -c arm-linux-gnueabihf

Problem 6 (Libtool error):

error: Libtool library used but 'LIBTOOL' is undefined.

apt install libtool
libtoolize

Finally rerun ./sdk/build-epiphany-sdk.sh -c arm-linux-gnueabihf one more time.

Hopefully if everything has gone well, your epiphany-SDK should now be installed.

Thanks @Owl3 for your solutions. Unfortunately we decided to move forward to another dev. platform because of the coming deadlines. Really appreciated your kindly help.
