rockboxdev.sh in Cygwin takes very long time

[AgentRev]

Hey there,

I followed the steps to install Cygwin on Windows in order to compile an ARM version of Rockbox, however I'm stuck at the rockboxdev.sh part. I started it like 6 hours ago, and it still seems executing, with text flowing normally in the console.

Most lines displayed starts with "/tmp/rbdev-build/build-gcc/[...]", is it possible that I need to try again by restarting the script, or it's normal it takes that long?

cygwin is extremely slow, so depending how old your machine is that might be reasonable.

It's a 3 GHz quad core.

Then it should go faster.

If it's still scrolling different text, it's working. It does take hours and hours on cygwin. Don't use cygwin if you can avoid it; development on linux (even in a virtual machine) is dozens of times faster.

Yeah, Cygwin is very slow. Here's a toolchain I compiled a while ago: http://dl.dropbox.com/u/16662598/Rockbox/arm-elf-eabi.tar.bz2

Definately. Took me ~6-8 hours under cygwin vs. 15-20 min under Ubuntu (in a VM) on the same machine (1.7 GHz i7).

Looks like it finished compiling in about 7 hours. Does a full Rockbox compile on Cygwin take a lot of time (say, more than 30 mins)?


P.S.: I added a note on the CrossCompiler wiki page about the script completion time for Cygwin.

I haven't done it in a while but it takes maybe 20 minutes, if I remember accurately. On the same machine with Linux it takes more like 3 minutes to build (rockbox is tiny compared to the GNU toolchain).

[AgentRev]

Took about 5 mins for a full Rockbox compile in Cygwin, with "make -j4". All CPU cores' usage was between 85 and 100% during the compile.

That's not terrible, but I expect it will still be significantly faster in Linux on that machine, then; under a minute?
