toolchain

问题 I have a project which has armeabi-v7a folder and uses libssl.a and libcrypto.a libraries. Now i am able to compile the project with the source code c++ files and use that into a project. Now i want cmake to create a shared library which i can use in any other project. I don't have much knowledge of cmake What i have tried? cmake -DCMAKE_TOOLCHAIN_FILE=$(NDK_PATH)/build/cmake/android.toolchain.cmake -DANDROID_NDK=$(NDK_PATH) -DANDROID_ABI=armeabi-v7a -DANDROID_PLATFORM=android-21 -DANDROID

问题 My goal is to make some new function to pnacl toolchain. Before I doing so, I think I should build the pnacl toolchain successfully first. [11/04 Update] Finally it works. Some package(bison, byacc, flex) I did't install and caused this problem. [11/03 Update] I use ubuntu-14.04.1-desktop-amd64 as my system Also, ubuntu-12.04.5-desktop-amd64 is now testing [11/03 updated] I've followed the step of the document all the way. Everything goes just fine until I run the toolchain_build_pnacl script

问题 I've been using buildroot in order to build a toolchain using uclibc . Now, buildroot downloads all the packages, extract them and build them all.. I want to change the toolchain's uclibc source and then recompile the toolchain with the new source and i just can't understand how it can be done in the pretty way.. After it finishes building, all of the extracted sources are found in the " <buildroot-src>/output/build ". But changing them won't give me a thing because buildroot only uses this

问题 What toolchain used by default when compile through Android.mk ? And how change the toolchain ? 回答1: The default toolchain was gcc-4.6 for a long time. It has changed to gcc-4.8 in the NDK r10d version (currently the latest version). You can choose to use another toolchain through modifying the NDK_TOOLCHAIN_VERSION variable, through ndk-build call (example: ndk-build NDK_TOOLCHAIN_VERSION=clang3.4 , or by setting it inside Application.mk file. Example: NDK_TOOLCHAIN_VERSION := clang3.4 来源：

问题 Using the default setup for Cygwin with codeblocks, I get the following error. "NameScanner - Debug" uses an invalid compiler. Probably the toolchain path within the compiler options is not setup correctly?! Skipping... Nothing to be done. I tried their custom installation instructions and that gave me this error on cstdlib , a default file C:\Dev-Cpp\bin\..\lib\gcc\mingw32\3.4.2\..\..\..\..\include\c++\3.4.2\cwchar|249|error: `::wcstold' has not been declared| C:\Dev-Cpp\bin\..\lib\gcc

问题 I am trying to build libraw as a Android shared library. It looks the lib is too complex to use with Android.mk etc, or better: I am not capable yet of doing that. I tried the route of using a standalone toolchain from the NDK, but I am getting stuck when compiling this lib. This is the path I take to compile the lib. Please point out if I am making obvious errors: I downloaded the ndk. ran: make-standalone-toolchain.sh Added the bin folder of that standalone toolchain as first item in my
