ChakraCore cannot build on Ubuntu 15.10 (x64)

[flyboy9]

Followed the information at http://ariya.ofilabs.com/2016/01/playing-with-chakracore-on-linux.html
except that I use virtualbox as the VM and install the ubuntu15.10 from http://releases.ubuntu.com/15.10/

the error message I am seeing is:

c++: error: unrecognized command line option ‘-fdelayed-template-parsing’

pal/src/CMakeFiles/Chakra.Pal.dir/build.make:54: recipe for target 'pal/src/CMakeFiles/Chakra.Pal.dir/cruntime/file.cpp.o' failed

@flyboy9 you need clang++3.7+

sudo apt-add-repository "deb http://llvm.org/apt/trusty/ llvm-toolchain-trusty-3.7 main"
sudo apt-get update
wget -O - http://llvm.org/apt/llvm-snapshot.gpg.key|sudo apt-key add -
sudo apt-get install clang++-3.7

You also need libicu

sudo apt-get install libicu-dev

It may ask you to install couple of more packages.

Check if you have clang++ on the path ? Otherwise

sudo ln -s /usr/bin/clang++-3.7 /usr/bin/clang++
sudo ln -s /usr/bin/clang-3.7 /usr/bin/clang

if you don't want to do that, you may set clang location using build.sh

./build.sh --cxx=/usr/bin/clang++-3.7 --cc=/usr/bin/clang-3.7

please let me know, so I can update this comment (eventually wiki)

[flyboy9]

hmm, followed you instruction, still seeing the same error

Question: is there a way for me to verify if the necessary develop environment is set up correctly?

[obastemur]

ling@ling-VirtualBox:~/Desktop/code/ChakraCore$ cmake . && make

Could you use build.sh option above with the explicit location for clang, and clang++ ?

update: -bash: ./builds: No such file or directory could you try build.sh instead ?

[obastemur]

from the long you have: ln: failed to create symbolic link ‘/usr/bin/clang’: File exists

where do you have the clang, and clang++ ?

update: and version of the clang installed ? clang -v ?

I also had difficulty building on Ubuntu 15.10. @digitalinfinity suggested that the version of cmake might be a problem. I tried to install the latest but ultimately updated to 16.04 LTS which included cmake 3.5.2, and was able to get a successful build.

[digitalinfinity]

With @obastemur's PR #913 now merged in, cmake 3.5 is no longer needed either so it should build fine with Ubuntu 15.10.

[dilijev]

@flyboy9 can you confirm that you're able to build and then we'll close this issue? :)

[obastemur]

I've just compiled ChakraCore on a new VM with the steps below;

• Visited http://releases.ubuntu.com/ and download latest LTS! (x64)
  How or to where you have installed doesn't make much difference.
  !Keep in mind you will need an internet connection on this VM
• Once you have Ubuntu is installed open a terminal window and start the update process
  Ø sudo apt-get update
  Ø sudo apt-get dist-upgrade
• Make sure you have git is installed
  Ø sudo apt-get install -y git
• Get the latest ChakraCore source code (ReadOnly option - Use your fork instead of Microsoft)
  Ø mkdir Github && cd Github
  Ø git clone https://github.com/Microsoft/ChakraCore
• The next step is to install some useful packages for better development experience (OPTIONAL)
  Ø sudo apt-get install -y meld
  Ø To install VSCode visit https://code.visualstudio.com/Docs/editor/setup#_linux
• Time to install dependencies
  Ø sudo apt-get install -y build-essential cmake clang uuid-dev libunwind-dev libicu-dev liblttng-ust-dev
• Let's build
  Ø cd ChakraCore
  Ø git checkout linux
• Finally
  Ø ./build.sh

Closing this issue for now. In case you are unable to compile using the steps above feel free to open this issue back. Thanks for all the details!

@Microsoft/chakra-developers what is the best way to share these steps above from our wiki on Github?

@obastemur : @liminzhu might be able to provide more guidance or integrate this into the wiki in an appropriate place.

[liminzhu]

// thanks for cc'ing me @dilijev

Great stuff @obastemur ! I was actually looking for such a guide. The most logical place in the current wiki would be Building ChakraCore and have a linux block in it. I can test it out today and add the guide there.

[obastemur]

@liminzhu sounds great. Thanks!

[liminzhu]

@obastemur Just add the guide there with slight tweaks of words.
