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; | ^~~~~~~~~ rrd_open.c:251:37: error: ‘MAP_PRIVATE’ undeclared (first use in this function) 251 | rrd_simple_file->mm_flags = MAP_PRIVATE; | ^~~~~~~~~~~ rrd_open.c:265:41: error: ‘MAP_SHARED’ undeclared (first use in this function) 265 | rrd_simple_file->mm_flags = MAP_SHARED; | ^~~~~~~~~~ rrd_open.c:266:41: error: ‘PROT_WRITE’ undeclared (first use in this function) 266 | rrd_simple_file->mm_prot |= PROT_WRITE; | ^~~~~~~~~~ rrd_open.c:424:12: warning: implicit declaration of function ‘mmap’ [-Wimplicit-function-declaration] 424 | data = mmap(0, rrd_file->file_len, | ^~~~ rrd_open.c:424:12: warning: nested extern declaration of ‘mmap’ [-Wnested-externs] rrd_open.c:424:10: warning: assignment to ‘char *’ from ‘int’ makes pointer from integer without a cast [-Wint-conversion] 424 | data = mmap(0, rrd_file->file_len, | ^ rrd_open.c:576:9: warning: implicit declaration of function ‘munmap’ [-Wimplicit-function-declaration] 576 | munmap(data, rrd_file->file_len); | ^~~~~~ rrd_open.c:576:9: warning: nested extern declaration of ‘munmap’ [-Wnested-externs] make[1]: *** [Makefile:1060: librrdupd_la-rrd_open.lo] Error 1 make[1]: Leaving directory '/c/arc/cygwin/software/librrd/rrdtool-1.7.2/src' make: *** [Makefile:503: install-recursive] Error 1
I didn't check every one of them, but these seem to live in /usr/include/sys/mman.h in my installation.
