Error on running `make` in root dir #179

Closed paramaggarwal closed 7 years ago

paramaggarwal commented 7 years ago

I cloned the repo and then ran make in root directory. I am getting this error consistently. Please help.

target/adiv5.c: In function 'adiv5_dp_init':
target/adiv5.c:391:11: error: variable 'ctrlstat' might be clobbered by 'longjmp' or 'vfork' [-Werror=clobbered]
  uint32_t ctrlstat = 0;
           ^~~~~~~~
cc1: all warnings being treated as errors
make[1]: *** [adiv5.o] Error 1
make: *** [all] Error 2

I reverted the changes in this commit https://github.com/blacksphere/blackmagic/commit/08c9ab54d7f6b3af8cf4399b6ed355b7fafa1bfe from August 2016, and the warning/error stopped.

I'm also having this issue on Linux and with the latest ARM toolchain version.

The error is the same.

@fcgdam You can go around this meanwhile by removing the -Werror parameter in this line: https://github.com/blacksphere/blackmagic/blob/master/src/Makefile#L13

fcgdam commented 7 years ago

Confirmed. It works now and outputs the firmware. Thanks.

I have documented some steps here: https://www.hackster.io/paramaggarwal/converting-an-stm32f103-board-to-a-black-magic-probe-e701d4

Thanks @gsmcmullin.
