opencv - Unable to build OpenCV2 since lots of Object-C error -


guys

i'm trying build opencv2 on os x 10.8.3 under this official installation guide.

the configure step works fine:

cmake -d:cmake_build_type=release ..

but when build make:

make -j 8

there turns out lots of object-c errors this:

/system/library/frameworks/foundation.framework/headers/nsstring.h:260: error: expected ';' before '__attribute__' /system/library/frameworks/foundation.framework/headers/nsstring.h:261: error: expected ':' before '(' token /system/library/frameworks/foundation.framework/headers/nsstring.h:261: error: expected type-specifier before '(' token /system/library/frameworks/foundation.framework/headers/nsstring.h:261: error: expected ')' before '(' token /system/library/frameworks/foundation.framework/headers/nsstring.h:261: error: expected identifier before '(' token /system/library/frameworks/foundation.framework/headers/nsstring.h:261: error: expected ';' before '(' token /system/library/frameworks/foundation.framework/headers/nsstring.h:262: error: expected ';' before '__attribute__'  in file included /system/library/frameworks/foundation.framework/headers/foundation.h:52,                  /system/library/frameworks/qtkit.framework/headers/qterror.h:8,                  /system/library/frameworks/qtkit.framework/headers/qtkit.h:11,                  /users/kuankuan/desktop/roysdata/workspace/opencv/opencv-2.4.5/modules/highgui/src/cap_qtkit.mm:34: /system/library/frameworks/foundation.framework/headers/nspointerarray.h:57: error: expected ';' before '__attribute__' /system/library/frameworks/foundation.framework/headers/nspointerarray.h:58: error: expected ';' before '__attribute__' in file included /system/library/frameworks/foundation.framework/headers/foundation.h:54,                  /system/library/frameworks/qtkit.framework/headers/qterror.h:8,                  /system/library/frameworks/qtkit.framework/headers/qtkit.h:11,                  /users/kuankuan/desktop/roysdata/workspace/opencv/opencv-2.4.5/modules/highgui/src/cap_qtkit.mm:34: /system/library/frameworks/foundation.framework/headers/nsport.h:68: error: expected constructor, destructor, or type conversion before '-' token[ 42%]  /system/library/frameworks/foundation.framework/headers/nsport.h:115: error: expected constructor, destructor, or type conversion before '-' token in file included /system/library/frameworks/foundation.framework/headers/foundation.h:57,

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
