odroid 커널 빌드(on odroid) 실패

크로스 컴파일은 잘만되던데.. 왜 얘는 안되나... 

include 헤더 문제일려나?

응?

하늘별 2013-08-20 09:55 220.90.137.100 github에 있는 커널은 리눅스용으로 안드로이드를 지원하고 있지 않습니다. BSP으로 따로 배포하는 커널을 사용 하시기 바랍니다.

GCC is taking steps towards C++11, which is probably why you now need to include cstddef in order to use the NULL constant. The preferred way in C++11 is to use the new nullptr keyword, which is implemented in GCC since version 4.6

설마.. c99 옵션 차이는 아니겠지?

찾아보니.. long-long에 가깝네..

--enable-c99 The long long type was introduced in C99, along with many other functions for wide characters, and math classification macros, etc. If enabled, all C99 functions not specified by the C++ standard will be put into namespace __gnu_cxx, and then all these names will be injected into namespace std, so that C99 functions can be used "as if" they were in the C++ standard (as they will eventually be in some future revision of the standard, without a doubt). By default, C99 support is on, assuming the configure probes find all the necessary functions and bits necessary. This option can change the library ABI.
