Trying to compile grep-2.28 on centos6.8 (32-bit, but I don't think that matters), with the system compiler (gcc 4.4.47-17) and system pcre, I get:
pcresearch.c:53: error: expected specifier-qualifier-list before 'pcre_jit_stack' That line is: pcre_jit_stack *jit_stack; And indeed, /usr/include/pcre.h does not contain anything about jit. Evidently it is too old. I suggest that the configure test for pcre be adjusted if you're going to require jit. With --disable-perl-regexp, all went through. --thanks, karl.
