Greetings, All!I'm trying to match my Cygwin PHP install with native one, and one of the steps is to build rrd extension. There's no librrd shipped with Cygwin, so I have to build that first. I've successfully configured it after installing of some -devel packages with `./configure --prefix=`, but compiling fails with rrd_open.c: In function ‘rrd_open’: rrd_open.c:166:22: error: ‘MAP_FAILED’ undeclared (first use in this function) 166 | char *data = MAP_FAILED; | ^~~~~~~~~~ rrd_open.c:166:22: note: each undeclared identifier is reported only once for each function it appears in rrd_open.c:239:32: error: ‘PROT_READ’ undeclared (first use in this function) 239 | rrd_simple_file->mm_prot = PROT_READ; | ^~~~~~~~~
Configure and make logs attached, as well as list of necessary -devel packages. I would appreciate any help with this issue.
the configure.ac has a test for sys/mman.h but it is not using in for Cygwin, no idea why It should be present in all enviroments but it seems they think ut is only need in some https://man7.org/linux/man-pages/man2/mmap.2.html HAVE_SYS_MMAN_H should be defined for a proper include, and with a proper define, it pass that obstacle. $ grep MMAN src/rrd_config.h #define HAVE_SYS_MMAN_H 1 there are later some missing libraries during linking -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
