Where are the hex files compiled by Arduino?

问题:

Where does the Arduino IDE save the binaries on Mac OS X?

回答1:

In the Arduino software: go to File -> Preferences and then select Show verbose output during -> compilation.

Finally, when you are compiling, the program will show you lots of data. At the last lines, you will find the path¹ to the .hex file.

¹Every time the path changes!

Arduino 1.6.5 has a new command: Under the Sketch menu, select Export compiled Binary, then Show Sketch Folder. There it is.

Arduino IDE uses the mktemp command to create the temp directory on Mac and Linux. However, on Mac the default $TMPDIR env var is not /tmp/ as it is on Linux. On Mac it's under /var/folders and it is randomly generated on boot. That complicates things a little, but here are tricks you can add to your toolkit (as aliases, functions, shell scripts, etc.) to help you find what you need.

To find the hex files

find $TMPDIR -name \*.hex -exec ls -lrt {} \; #<-- you need that backslash before and space after the semicolon

To find build directories

ls -ldrt $TMPDIR/build*

NOTE: The ls flags of r and t cause the listing to be "reverse" sorted by "time" respectively. This means that the newest will be on the bottom.

What UDalillu said. The trick also works on Windows. On XP it ended up in C:\Documents and Settings\Your_User_Name\Local Settings\Temp\buildxxxxx\ (the xxx number changes for each build, pick the most recent).

回答5:

The arduino web page http://arduino.cc/en/Hacking/BuildProcess described

During a "Verify" the .hex file is written to /tmp (on Mac and Linux) or \Documents and Settings\\Local Settings\Temp (on Windows)

I am using fedora19 64bit, and when i check my /tmp the build directory created is /tmp/build8102....tmp/

I made a simple tutorial here with images

It is very beautifully explained in the following blog Where to find Arduino Hex files or Output Binaries I hope this helps :)
