[osg-users] Android osgPlugins

[Christian Kehl]

Hi,

So, what I tried now is to revert to the old OpenSceneGraph. I was looking up in the internet for the rand() error on the android platform, where people say <cstdlib> needs to be explicitly included in the header that uses the function. The stat64 error is an ample ifdef construct in OpenSceneGraph/src/osgDB/FileUtils.cpp. I tried to add there the following (osg svn version 3.3.3)


    #if defined(GL_VERSION_ES_CM_1_0) || defined(GL_VERSION_ES_CM_1_1) || defined(GL_VERSION_ES_2_0) || defined(GL_VERSION_ES_1_1) || defined(GL_VERSION_ES_1_0)
        // if we are on android,we need to obscure the 64-bit pointer (needs to be adapted for android >=r10c
        // due to 64 bit support)
        #define stat64 stat
    #endif

(line 93, after the switch for _DARWIN_FEATURE_64_BIT_INODE)

still, the work is unsuccessfull as I still get the same errors.

Thank you!
