I actually used it in my reply to your original post: On 14 June 2015 at 12:45, Matthijs van Duin <[email protected]> wrote: > [..] compile it with "arm-linux-gnueabihf-gcc -Og -S -o- foo.c" > The options I use here: -Og a very mild optimization level (milder even than -O1), most likely to produce very straightforward assembly output. (Introduced in gcc 4.8) -S produce assembly output instead of object code -o - send output to stdout (you can send it to a file instead of course) I do suggest you upgrade your rather dated 4.7.x compiler to a more recent one, either 4.9.x or 5.1.x. Debian "stretch" (testing) and "sid" include a "gcc-5-arm-linux-gnueabihf" package. The distro-independent Linaro toolchains are a useful alternative. They're good toolchains for various ARM targets, both linux (64-bit) and windows (32-bit) hosts, and completely standalone (just unpack the archive anywhere and put its "bin" subdir in your PATH). They are a bit annoying to locate in their download area however. I don't know of a better way to find the most recent version than checking the directory for each month to see which one contains a "components/toolchain/binaries/arm-linux-gnueabihf" subdir. Their most recent version currently seems to be the 2015.02 release <http://releases.linaro.org/15.02/components/toolchain/binaries/arm-linux-gnueabihf> (you only need the gcc download). Finally, although cross-compiling is faster you can of course also just compile on the beaglebone itself. The native gcc is 4.9.2 in debian "jessie" (stable) and gcc-5 is available in "stretch". -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
