无法使用boost.sh脚本生成的Boost框架cmake cpp-netlib

Question

I am trying to compile cpp-netlib with cmake.

My config: OS X 10.9.1 Mavericks + Xcode 5.0.2 cpp-netlib 0.11.0 cmake 2.8.12.2 Boost 1.55.0

Because I am trying to make the whole thing work with OS X and iOS 7, I've made a Boost framework by using the following script: https://github.com/mgrebenets/boost-xcode5-iosx

I did a clean install with no c++11 as in example: "$ ./boost.sh clean -v 1.55.0"

This produced two "boost.framework" directories one for OS X, the second one for iOS. I have successfully added the OS X Boost framework to my Xcode project in "Build Phases > Link Binary With Libraries" and tested the boost::regex example from Boost documentation which worked fine on my Mac.

However, when I started cmaking the cpp-netlib, I ran into problems. When I try to run this:

$ cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ ../cpp-netlib-0.11.0-final/

It produces the following output:

-- The C compiler identification is Clang 5.0.0
-- The CXX compiler identification is Clang 5.0.0
-- Check for working C compiler: /usr/bin/gcc
-- Check for working C compiler: /usr/bin/gcc -- works

I have tried setting the BOOST_ROOT environmental variable to "path_to_framework/boost.framework/" and "path_to_framework/boost.framework/Versions/A/" I've also tried setting BOOST_INCLUDEDIR to "path_to_framework/boost.framework/Versions/A/Headers/" directly to the headers directory.

Unfortunately I am still getting the same errors every time...

Can anyone please help me setup cpp-netlib for use with iOS 7? My head is currently overwhelmed by all the compilation/requirements/libraries/etc in c++. I come from a web programming background and used PHP, JavaScript, quite a lot MS PowerShell (yeah, i know... =) ), as well as a bit of Java in the past, but C/C++ is new to me...please be gentle with a newbie =)

Thanks, Simon

您需要在cmake调用中添加-DBOOST_ROOT=/path/to/your/boost 。
