Hello!
I have a problem when executing make BOARD=stm32f4discovery in the directory: $(RIOT)/examples/hello-world/. The output is like this:
I use the cross complier “gcc-arm-none-eabi-4_8-2014q2” and set the $PATH correctly.
Something seems wrong because some of the exectuable files are vacuum, like this
Then execute arm-none-eabi-gcc -v,there is no response,like this.
How can I solve this problem and let the system work? T_T Thanks for your reading!

Hi Dongyu,
the empty entries should be links to corresponding files in other directories.
For example /opt/arm-none-eabi-4_8-2014q2/bin/arm-none-eabi-gcc should be a link to /opt/arm-none-eabi-4_8-2014q2/arm-none-eabi/bin/gcc
I suggest that something went wrong during decompression of the gcc-arm-none-eabi-4_8-2014q2-20140609-linux.tar.bz2 archive to /opt/.
You could try to decompress the archive somewhere in your home directory, and check if you can run the arm-none-eabi-gcc -v from there.
Best regards, Martin
I think your PATH does not include the directory where arm gcc lives or your extraction process went wrong.
To check the PATH go in a random directory (e.g. your home or RIOT folder) and enter
arm-none-eabi-gcc -v
On my machine this shows:
$ arm-none-eabi-gcc -v Using built-in specs.

The right tar file is available via this page:

For the Cortex CPUs we recommend the Linaro package, for ARM7 the Codebench.
Let us know what the solution is!
