Problem compiling ofxMaps on OS X

Hi all,

I really hope someone can help me with this, I don't really know neither Macs nor c++. I am having a problem compiling ofxMaps under Mac OSX, but the problem occurs for ofxHTTP files (like BaseRouteSettings.cpp or FileSystemRoute.cpp). The machine specs are currently OS X Yosemite:

 $ sw_vers 
 ProductName:    Mac OS X
 ProductVersion:    10.10.3
 BuildVersion:    14D131
 $ system_profiler SPSoftwareDataType
 Software:

     System Software Overview:

       System Version: OS X 10.10.3 (14D131)
       Kernel Version: Darwin 14.3.0
       Boot Volume: Macintosh HD
       Boot Mode: Normal
 $ uname -a
 Darwin XXXX 14.3.0 Darwin Kernel Version 14.3.0: Mon Mar 23 11:59:05 PDT 2015; root:xnu-2782.20.48~5/RELEASE_X86_64 x86_64

On this machine, there is Xcode Version 6.3.2 (6D2105), which has OS X SDK 10.10 and 10.9 - and I also found an older Xcode dmg, from which I grabbed OS X SDK 10.8 and copied it for this Xcode.

After a ton of problems, I managed to have something of an xcode project file, that looks like it is compiling, except that it fails here. First I had to get of_v0.8.4_osx_release so I have a working projectGenerator_osx, which helped me generate the Xcode project, which I then had to edit manually (adding all ofxMaps dependencies as "Groups" under addons, so they compile; adding openFrameworksDebug.a that was missing from "Target / Build Phases" in Xcode). That didn't want to compile, so I moved onto openFrameworks from git. Note that I already cloned the dependencies from https://github.com/bakercp (that is, ofxGeo, ofxSpatialHash, ofxIO, ofxTaskQueue, ofxHTTP, ofxSSLManager, ofxMediaType, ofxNetworkUtils, ofxMaps) into addons/ subdirectory for both cases.

Anyways, this example, including the .xcodeproj, is packed as a zip here:

ofxMaps_example.zip (79.6 KB)

... and I got it after running these commands in its directory:

xcodebuild clean
xcodebuild -configuration Debug clean 
make clean
make CleanDebug
# make -qp | awk -F':' '/^[a-zA-Z0-9][^$#\/\t=]*:([^=]|$)/ {split($1,A,/ /);for(i in A)print A[i]}' # to see make options

I am adding ofxMaps_example under examples/addons/ subdirectory.

The log after doing:

xcodebuild -configuration Debug 2>&1 | tee ../ofxm-xcode.log   # `build` is assumed

... can be found here: ofxm-xcode.log.h (194.3 KB, .h added just for the uploader)

After that I run the usual make:

make Debug 2>&1 | tee ../ofxm-make.log

... and the log for that can be found here: ofxm-make.log.h (233.6 KB, .h added just for the uploader)

In case of Xcode build, the error starts with:

...
CompileC build/ofxMaps_example.build/Debug/ofxMaps_example.build/Objects-normal/i386/FileSystemRoute.o 
...

        {return __x < __y;}
                ~~~ ^ ~~~
...

... which I find rather weird, because:

FileSystemRoute.cpp:26: #include "ofx/HTTP/FileSystemRoute.h"
FileSystemRoute.h:29:   #include "ofx/HTTP/BaseRoute.h"
BaseRoute.h:29:         #include <string>

... and so the errors happen basically when <string> is #included - at which point there shouldn't be any mixups with Poco::Net::MediaType??

The error during make is quite similar - except it happens during compiling a different file:

Compiling ../../../addons/ofxHTTP/libs/ofxHTTP/src/BaseRouteSettings.cpp

        {return __x < __y;}
                ~~~ ^ ~~~
...

So, why does this error occur - and how can I get this example to compile on Mac OSX?

Thanks in advance for any answers,
Cheers!

EDIT: I also tried the following:

• built openFrameworks_git/apps/projectGenerator/projectGeneratorSimple/bin/projectGeneratorSimpleDebug.app , which went fine
• used projectGeneratorSimpleDebug.app to generate a new project skeleton for example_basic_client under openFrameworks_git/examples/addons/, with only ofxHTTP (and no others) as an addon
• copied src/ and bin/data/ content from openFrameworks_git/addons/ofxHTTP/example_basic_client (the one gotten from git) into the project-generated example_basic_client
• tried to build the project-generated example_basic_client

... and also this one fails with /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/__functional_base:63:21: Invalid operands to binary expression ('const Poco::Net::MediaType' and 'const Poco::Net::MediaType')

So I guess if example_basic_client of ofxHTTP gets fixed, also my original query will get fixed... Let's hope someone has a pointer or two about this...
