Is it possible to install cross compiler on Raspbian? I mean arm-linux-gcc. I would like to try compile cross platform project on Raspbian instead of on virtual machine with Ubuntu.

I can't think of any obvious technical reason why one could not compile a cross compiler and run it on Raspbian ... but I think you will be dissapointed by the results. Compilers are heavy users of the file system. They read and write files multiple times as we go fro source to assembler to object code and more. I/O operations on the PI using a micro SD card must be be a lot slower than corresponding I/O operations on a PC hard disk.– KolbanCommented Jul 22, 2016 at 13:05

@Kolban That's irrelevant. The bottleneck when compiling is almost always (including, or especially, in this case) the CPU; compiling is a CPU intensive activity, not an I/O intensive activity. "They read and write files multiple times..." -> Yes, in relatively small volumes. E.g. It might take upwards of an hour (perhaps, several) to compile a hundred MB or so worth of kernel and modules on a Pi 2. To copy the same volume back and forth to the SD card would take less than 1 minute, even with a slow card.– goldilocks ♦Commented Jul 22, 2016 at 13:59

This does not make sense, particularly if you are using an ARMv7 Ubuntu distro.
"Cross-compiling" refers to compiling for one architecture (such as ARMv7) on a platform with a different architecture (such as x86-64, which is probably what your normal computer is).
If you want to compile code for a given platform on that platform, you are not cross-compiling, you are just compiling.
The arm-linux-gcc cross-compiler available on most mainstream linux distros targets ARMv7. However, if you are running on an ARMv7 platform already, all you need is the normal compiler. In other words:
apt install gcc
You now have an ARMv7 compiler installed. If you wish to compile code for the pi on the pi, that's what you should use, just the same as you would normally anywhere else.
