For a moment I build it on N900, following your instruction in other thread. EDIT: It again failed in opengl check - "The EGL functionality test failed! EGL is required for OpenGL ES to manage contexts & surfaces. You might need to modify the include and library search paths by editing QMAKE_INCDIR_EGL, QMAKE_LIBDIR_EGL and QMAKE_LIBS_EGL in /root/qt4-x11-4.6.2~git20100401/mkspecs/linux-g++-maemo5." Both packages - opengles-sgx-img-common-dev and libgles2-sgx-img-dev are installed as so as non "-dev" versions.
