问题 I left Eclipse to NetBeans for C/C++ development right after release v7 and it all seems a wise choice except that -std=C++11 flag in the current latest release, namely 7.2, is not recognized by gcc 4.6 ( -std=C++0x ) or the previous.

问题 I want to create an system application(while installing it will ask user permission to make it as system app) for UN-rooted application. As I am not familiar in android, please tell me how to create it. Thanks in advance. 回答1: True system apps are baked into the ROM image, and signed with the same key the ROM was signed with, giving them extra access to the system. You cannot add a new system app on the same level without updating the ROM image of the device, and even then you'll need the OEM

问题 I have an rpm and I want to treat it like a tarball. I want to extract the contents into a directory so I can inspect the contents. I am familiar with the querying commands of an uninstalled package. I do not simply want a list of the contents of the rpm. i.e. $ rpm -qpl foo.rpm I want to inspect the contents of several files contained in the rpm. I do not want to install the rpm.
