hi,
I changed the default compiler to the g++-6 (installed by brew )

[yarcowang]

After upgrade to g++-6, then do CXX=g++-6 make, i got:

...
g++-6 -Wall -c -std=c++11 -fvisibility=hidden -DBUILDING_PHPCPP -Wno-write-strings -g `php-config --includes` -fpic -o shared/zend/zval.o zend/zval.cpp

Change -soname to -install_name

[yarcowang]

After change lineno 179 (makefile) from

    ${LINKER} ${PHP_LINKER_FLAGS} -Wl,-soname,libphpcpp.so.$(SONAME) -o $@ ${COMMON_SHARED_OBJECTS} ${PHP_SHARED_OBJECTS}

To

    ${LINKER} ${PHP_LINKER_FLAGS} -Wl,-install_name,libphpcpp.so.$(SONAME) -o $@ ${COMMON_SHARED_OBJECTS} ${PHP_SHARED_OBJECTS}

Then i got this:

      Php::StreamBuf::sync()    in streambuf.o
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
make: *** [libphpcpp.so.2.0.0] Error 1

Maybe i shouldn't compile it under mac?

[willianszwy]

you need add -undefined dynamic_lookup to LINKER_FLAGS

[yarcowang]

@willianszwy
Yes, finally make it done.

Here are the steps for those who want to compile it under mac.

1. You should use gcc version of the c++ compiler g++-6 (not the apple one, clang++)
2. You should change lineno(in makefile) 119 to add -undefined dynamic_lookup config like the document said, so the LINKER_FLAGS becomes:
   LINKER_FLAGS = -shared -undefined dynamic_lookup
3. You should also change lineno(in makefile) 179 from -soname to install_name, so the that line becomes:
   ${LINKER} ${PHP_LINKER_FLAGS} -Wl,-install_name,libphpcpp.so.$(SONAME) -o $@ ${COMMON_SHARED_OBJECTS} ${PHP_SHARED_OBJECTS}
4. Finally you run it as CXX=g++-6 make
5. Done

Forgot to say thank you, @willianszwy
