Trouble building 17.01 from source on x64

For Developers
1

in source/feeds/packages/utils/xz/Makefile, I see --disable-assembler but when attempting to build LEDE 17.01, I get errors that look like the --disable-assembler directive is not being respected

check/crc32_x86.S: Assembler messages:

OK, I managed to fix xz compiling by adding --disable-assembler to source/tools/xz/Makefile

Now gmp is failing with:

Thanks, that helped

Not sure what is going on there, but I've never seen anything like that.

I'd guess that your build environment hasn't been installed properly or your missing required packages on your host OS.

Same here, x86 is one of the most tested platforms I reckon, and last time I compiled the 17.01 tree everything went without a hitch.
