Happens during make.

Dependencies/subdependencies installed:

  • libevent2.1.8
  • libevhtp
  • oniguruma
  • rocksdb
  • univalue
  • OpenSSL 1.0.2

What could be wrong?

I have the same error

alex@ubuntu:~/cpptrade$ make
make all-am

It seems need to install oniguruma before libevhtp, if not, it will define EVHTP_DISABLE_REGEX during we build libevhtp.
#ifndef EVHTP_DISABLE_REGEX EVHTP_EXPORT evhtp_callback_t * evhtp_set_regex_cb(evhtp_t * htp, const char * pattern, evhtp_callback_cb cb, void * arg); #endif
