asm/socket.h: No such file or directory cross compiling Dart for Raspberry pi

Question

I'm cross-compiling the Dart runtime using the instruction here.

I've installed all the dependencies as specified. I've also cloned the git repository with the necessary tool chain.

I'm running the runtime compilation with this command:

./tools/build.py -m release -a arm --toolchain=../tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf runtime

The compilation starts with no problem then it stops with this error:

BUILD FAILED

Am I missing any dependency or package?

Answer 1

This is probably because you're trying to build an application without some of the include paths correctly set, for example using a 32-bit gcc on a 64-bit platform. To resolve:

sudo apt-get install gcc-multilib

Answer 2

I'm not sure why this happens, but sometimes /usr/include/asm gets deleted. My teammates who looked at their Ubuntu x86-64 workstations found that the asm symlink was:

0 lrwxrwxrwx 1 root root 20 May 22  2013 /usr/include/asm -> x86_64-linux-gnu/asm

And the command to recreate it is:

$ cd /usr/include
$ sudo ln -s x86_64-linux-gnu/asm asm

The files in /usr/include/asm-generic are sometimes, but not always, equivalent to the files in the x86-64 specific directory; so it's difficult to recommend symlinking it as a workaround.

Answer 3

I hit the same problem. On my ubuntu 14.04 system /usr/include/asm didn't exist. It was called asm-generic instead. I sym-linked it and the build was able to continue.

cd /usr/include
sudo ln -s asm-generic/ asm

The build was able to continue after that.
