Build error on Arch Linux.

ghost commented 5 years ago

Hello dear team of Proxmark!

I'm trying to build proxmark3 (git 2337 commit) on Arch Linux (gcc version 9.1.0), but I get this error:

appmain.c: In function 'UsbPacketReceived':
appmain.c:1001:40: error: taking address of packed member of 'struct <anonymous>' may result in an unaligned pointer value [-Werror=address-of-packed-member]
 1001 |    setSamplingConfig((sample_config *) c->d.asBytes);
      |                                        ^
cc1: all warnings being treated as errors
make[1]: *** [../common/Makefile.common:81: obj/appmain.o] Error 1
make[1]: Leaving directory '/home/user/src/proxmark/armsrc'
make: *** [Makefile:31: armsrc/all] Error 2
==> ERROR: A failure occurred in build().
    Aborting...

Thanks in advance!

Which ARM toolchain is included with your Arch Linux? Please type

arm-none-eabi-gcc --version

and post the result.

I am not using gcc 9.1.0 yet (not sure if it is available at all for Windows). Tried to fix with PR #869 nevertheless. Please give it a try. There might be more of this kind of warnings...
