5 years ago For those who have the same problem, the correct 32-bit library in this specific case is:
/usr/lib/gcc/x86_64-linux-gnu/5/32/libgcc.a
Note the subtle difference of using the 32 subdirectory instead of x32
I am getting this error when I make xv6. I am unsure where the issue is at. I'm compiling on an x86-64 Ubuntu system: Linux version 4.4.0-64-generic (buildd@lgw01-56) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4) ) #85-Ubuntu SMP Mon Feb 20 11:50:30 UTC 2017
