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

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.

Answer 2

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 3

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.
