Hi, Not sure if it is appropriate to post to this list with muchsync questions but if not could someone let me know... I'm trying to compile muchsync from git on OSX, I noted that the announcement said it should compile cleanly. I get the following when trying to compile: make g++ -DPACKAGE_NAME=\"muchsync\" -DPACKAGE_TARNAME=\"muchsync\" -DPACKAGE_VERSION=\"2\" -DPACKAGE_STRING=\"muchsync\ 2\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE_URL=\"\" -DPACKAGE=\"muchsync\" -DVERSION=\"2\" -DHAVE_OPENAT=1 -DHAVE_FDOPENDIR=1 -DST_MTIM=st_mtimespec -I. -I/usr/local/Cellar/xapian/1.2.19/include -g -O2 -std=c++11 -Wall -pthread -MT infinibuf.o -MD -MP -MF .deps/infinibuf.Tpo -c -o infinibuf.o infinibuf.cc mv -f .deps/infinibuf.Tpo .deps/infinibuf.Po g++ -DPACKAGE_NAME=\"muchsync\" -DPACKAGE_TARNAME=\"muchsync\" -DPACKAGE_VERSION=\"2\" -DPACKAGE_STRING=\"muchsync\ 2\" -DPACKAGE_BUGREPORT=\"\" -DPACKAGE_URL=\"\" -DPACKAGE=\"muchsync\" -DVERSION=\"2\" -DHAVE_OPENAT=1 -DHAVE_FDOPENDIR=1 -DST_MTIM=st_mtimespec -I. -I/usr/local/Cellar/xapian/1.2.19/include -g -O2 -std=c++11 -Wall -pthread -MT misc.o -MD -MP -MF .deps/misc.Tpo -c -o misc.o misc.cc In file included from misc.cc:11: ./misc.h:10:10: fatal error: 'openssl/sha.h' file not found #include <openssl/sha.h> > ^ 1 error generated. make: *** [misc.o] Error 1 And if it is of use here is the configure: checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... ./install-sh -c -d checking for gawk... no checking for mawk... no checking for nawk... no checking for awk... awk checking whether make sets $(MAKE)... yes checking whether make supports nested variables... yes checking for g++... g++ checking whether the C++ compiler works... yes checking for C++ compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU C++ compiler... yes checking whether g++ accepts -g... yes checking for style of include used by make...
