* Support host multilib buildYing Wang2014-05-141-29/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change basically ported our target multilib to the host side. It supports 2 host build modes: x86 and x86_64 multilib build. For now you need to set "BUILD_HOST_64bit=true" to switch to x86_64 multilib build. Later we'll default to x86_64 build and have a flag to force 32-bit only build, which may be needed by SDK build. In host module definition, like in target ones, you can use the following LOCAL variables to set up multilib configuration: LOCAL_MULTILIB: can be "both", "first", "32" or "64". It also supports the same set of arch or 32-vs-64 specific LOCAL variables. By default, it builds only for the first arch. To keep path compatibility, in x86_64 build files are still output to out/host/linux-x86; Both 32-bit and 64-bit executables are in out/host/linux-86/bin; In x86_64 build 32-bit shared libraries are installed to out/host/linux-x86/lib32 and 64-bit shared libraries are installed to out/host/linux-x86/lib; 32-bit object files are output to out/host/linux-x86/obj32 and 64-bit object files are output to out/host/linux-x86/obj.

* Disable canonical prefixes of system headersAndrew Hsieh2014-05-091-1/+2
| | | | | | | | | | | | | | | | | GCC know a few pre-defined paths (relative to its location) to search for headers, libraries, program, etc. By default GCC prefixes its own path(argv[0]) and calls realpath() which result in absolute path with all symlink, . and .. removed. It's usually good to have canonicalised paths, but absolute paths in *.d file can cause unnecessary relinking when stale entries in ccache cache hit Add -no-canonical-prefixes (gcc>=4.6) and -fno-canonical-system-headers (gcc>4.6) to disable realpath() on prefixed paths Change-Id: I58d739e61fb013015fb05a9c98b2132b307f915a

* Enable NX protectionsJoshua J. Drake2013-12-121-4/+4
| | | | | | | | | | | Add -Wa,--noexecstack and -Wl,-z,noexecstack as default flags when compiling host-side applications. This enables NX protections, which prevent code from executing on the stack or heap. NX protections make exploiting memory corruption issues more challenging and is an important security feature.

* HOST_linux-x86: Avoid doubly define macro _FORTIFY_SOURCEJim Huang2011-11-101-1/+1
| | | | | | | | | | | | | | | | While building Android with latest host gcc, it causes the following build error: Install: out/host/linux-x86/bin/mkbootimg host C++: obbtool <= frameworks/base/tools/obbtool/Main.cpp <command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror] <built-in>:0:0: note: this is the location of the previous definition cc1plus: all warnings being treated as errors In order to make build system happy, this patch does unset macro _FORTIFY_SOURCE and then define it in host cflags.

* Add support for custom Linux host toolchains when building the SDK.David 'Digit' Turner2010-12-131-0/+20
| | | | | | | | | | | | This is needed in order to build Linux SDK binaries that can run properly on Ubuntu 8.04 (Hardy). By default, the host toolchain on 10.04 (Lucid) generates machine code that won't run on Hardy due to GLibc ABI mistmatches. Note that nothing happens if the new toolchain is not in the prebuilt tree. Change-Id: I45c1f68e37e15a0032f885df1c5c0f297b3d8642

* Get rid of $(combo_target)Jean-Baptiste Queru2010-02-231-0/+37
The only OS-ARCH combo that would have benefited from it is linux-x86, but it explicitly used separate configurations for the HOST_ and TARGET_ side of things. This makes is clear which files are related to the HOST_ configuration and which ones are related to the TARGET_ configuration, and expands $(combo_target) to the only possible/reasonable value that it could have had in every file. This also cleans up the simulator, by moving it in a single place in TARGET_linux_x86 (since the only part that's special is to use HOST_ settings even when building TARGET_ modules).
