If Mbed OS is open source then why do you have to use a cloud compiler to compile the software? Is the source code for Mbed OS open but the the cloud compiler is closed source?
Just looking for clarification amongst marketing jargon.

There seems to be some confusion here between Mbed OS which is a open source project and the Mbed Compiler Service, which is a tool that makes getting started with Mbed OS super easy.
Mbed OS is open source, you can find it here : http://github.com/armmbed/mbed-os, i encourage you to contribute by submitting a Pull Request.
The online compiler service is run by the Arm Mbed team to provide an easy way to get started with compiling your programs (there are some assumptions and sensible defaults in place so everything 'just works'). You can export your programs to a 3rd party compiler like Keil, IAR, or GCC / Eclipse for debugging if you need it. You can also use Mbed CLI offline to compile your code using GCC. (Fun fact, Mbed CLI is the same set of command line tools the online compiler uses).
Additional fun fact, the online compiler is using armcc (the same one that comes with Keil) where as GCC is the default for Mbed CLI (though if you have a liscense for armcc or iarcc you can use those with Mbed CLI as well.
Mbed OS is completely open source. There are various options to compile. So far, there are 3 toolchains that are supported by ARM mbed:
GCC ARM
ARMCC
IAR
Out of these 3, only GCC ARM is free while others have free evaluation versions with limited features unless you buy them.
In short, you can download mbed OS and then compile it for a target using any of the toolchains which may or may not be open source.

Looks like available Pascal compilers can only produce binaries for ARM on Linux. Is there established version of compiler/bundle for just bare ARM cpu with zero extra software preinstalled ?
To clarify, I am looking for high quality, compact tool (alternative to commercial C, open source C) for kernel-less, plain embedded CPU with all software in one plain ROM ? IDE with debugging capabilities is nice to have, but not necessary. Dubugger could actually be some different 3rd party generic IDE. I hope that compilers can dump the debug/symbols info in some standard form.
Thank you
Free Pascal Compiler supports ARM without any OS. They call it TARGET EMBEDDED.
For ARM Linux take a look at this and this.
There is also Lazarus CT edition cross compiler which seams to target sysless ARM too.
UPDATE 1: mikroElektronika has also recently made Pascal compiler for ARM.
UPDATE 2: Ultibo framework for bare metal Raspberry Pi programming looks outstanding.
I'm thinking about using a microcontroller with an 8051 core from Silicon Laboratories.
I hope that I can use C rather than assembly language, so I installed SDCC.
I installed the "Silicon Laboratories IDE" to download the executable binaries to the on-chip Flash program memory.
It also supposedly can be set up (under the Project > Tool Chain Integration menu)
to use "any" 8051 compiler.
I tried to set it up to use SDCC, but every time I hit the "Assemble/Compile File" button it tells me
"Compiler process did not sucessfully complete."
How do I get new C code I write onto the SiLabs C8051F310 chip?
Is there a web site with a step-by-step HOWTO?
(Would it be easier to use a MAKEFILE that calls SDCC, only using the "Silicon Laboratories IDE" for the very last step of downloading the executable binary to the chip?)
Start with Silicon Labs Application Note 198 - INTEGRATING SDCC 8051 TOOLS INTO THE SILICON LABS IDE*. It is written for an older version of the IDE, but the general configuration should remain the same. It is probably important to note that AN198 needs updating for SDCC 3.0.0. Additional information from the Silicon Labs MCU User Forum or Microcontrollers Knowledge Base may prove useful as well.
The SDCC Compiler User Guide* can be useful if additional command line options are desired.
The Silicon Labs USB Debug Adapter can be used with the Silicon Labs IDE and the on-chip debug/programming circuitry of the C8051F310* for programming the MCU and debugging your code.

I've got a programming device called USB AVR JTAG-ISP v. 1.2.
Where can I find drivers and a good IDE for it?
For Windows, AVR Studio 4 as per the other answer.
For Linux, you want the avr-gcc and AVRDUDE packages from your OS distribution, plus your choice of C IDEs for Linux.
For OS X, you want Crosspack and Xcode.
On Linux or OS X, depending on which device you are programming, you may need to download the source for AVRDUDE and rebuild it, which will require that you also get libusb 0.1.12 (not libusb 1.x).
Try the "AVR Studio 4" on Atmel's website.
I find AVR studio to be infuriating, buggy and generally terrible.
Eclipse (available on all platforms) has wonderful end-to-end AVR integration available if you install the avr plugin, avr-gcc and avrdude.
If you're running on Ubuntu beware that it doesn't always identify the ISP right off the bat
Seems like there wouldn't be, but it would help us out if there was. I wish to pull the source down to a windows server and compile it and have it be the same as if I had pulled the source code down to a mac machine and used xcode on it. Any Ideas?
Reasons: Release Engineering and IT are much more familiar and comfortable on windows, so it would be easier on us, and LaunchD sucks.
Your original question had less detail... I think you are creating more problems than you are solving buy not using a Mac. Is it really that hard to learn to compile under Xcode or type make in the console?
Anyway...
Apple uses a modified version of the GCC C/C++/Objective C compiler with a proprietary runtime library... You could develop using a port of this code to Windows. See GNUStep.Org. This is not binary compatible though but it isn't impossible that you could rebuild it to cross compile to something that was Mac OS X compatible.
Another idea would be to develop using c# .NET and then move the binaries across to Mac OS X and run the binaries using Mono....
None of these options are robust enough to allow you to do this blind without a Macintosh to test and get up and running in the first place.
You can compile cross app with Cocotron but only on Mac
Why do you need launchd? cron works just as well on Mac as it does on Linux, just have a cronjob that does (Extremely simplified version ahead):
cd /my/source/dir
git pull # You are using Git, right?
xcodebuild MyCoolProject.xcodeproj
cp -r build/MyApp.app /the/distribution/folder
I'm doing a little app that I want to distribute in different platforms, at least the 3 major ones.
Is it possible to use only Windows has the host OS to compile the binaries for Linux, Mac OS X and other supported platforms without resorting to virtual machines?
Or should I ask around in some community to help me compile on, well OS X, actually, since I can virtualize a Linux machine quite easy?
It is possible to compile from one plateform to another, it is called cross-compilation. You will find extensive informations at http://www.stack.nl/~marcov/buildfaq.pdf
The buildfaq above contains sample cross-compilation :
from Windows to Linux,
from FreeBSD to AMD64 Linux
The FPC download page contains :
the i386-win32 to x86_64-win64 cross-compiler
the i386-win32 to arm-wince cross-compiler
The FPC mailing lists are at http://www.freepascal.org/maillist.var
You will find more informations about FPC at http://www.freepascal.org/moreinfo.var
(I'm the author of the buildfaq document above)
There are some limitations. You can't target x86 from powerpc, because powerpc misses an "extended" type. But in generally it works.
I have generated a complete Lazarus for OS X on Windows.
I would virtualize Linux, as even if you can cross-compile, it means you're not testing the binaries on their native platforms. OS X is a trickier problem.
It is not possible to compile from one platform to another. We have a Mac and use FPC quite often. If you need some help with compiling on a mac, drop me a message.
