sh make.sh error

I use python3.6(anaconda) and CUDA8.0 and sm_52(TITAN X) when I run sh make.sh, error occurs: Traceback (most recent call last): File "/home/zhushiwei/anaconda3/lib/python3.6/distutils/unixccompiler.py", line 118, in _compile extra_postargs) File "/home/zhushiwei/anaconda3/lib/python3.6/distutils/ccompiler.py", line 909, in spawn spawn(cmd, dry_run=self.dry_run) File "/home/zhushiwei/anaconda3/lib/python3.6/distutils/spawn.py", line 36, in spawn _spawn_posix(cmd, search_path, dry_run=dry_run) File "/home/zhushiwei/anaconda3/lib/python3.6/distutils/spawn.py", line 159, in _spawn_posix % (cmd, exit_status)) distutils.errors.DistutilsExecError: command 'gcc' failed with exit status 1

@Tuyota i had the same problem. note the error: 'for' loop initial declarations are only allowd in C99 or C11 mode(for (size_t i =0 ; i<=len; i++)). it seems like the 'i' need to be declared first.
So, i solved the problem by modify the THMath.h . like size_t i =0; for (i;i<=len;i++) ...
