android-ndk-r9 

Olá,

Minha máquina host éFedora 19 e eu quero criar uma cadeia de ferramentas para compilar programas para rodar no android, depois eu quero estender isso para iOS.

Estou tendo o erro a seguir:

Check for working C compiler: /opt/ndk/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc -- broken

Não tenho certeza porque estou recebendo esse erro, pois tudo foi instalado. Eu também instaleibinutils-arm-linux-gnu. No entanto, esta é a primeira vez que faço esse tipo de coisa, então tenho algo confuso.

Eu estou tentando criar um arquivo toolchain usando cmake para croos-compilar para executar bibliotecas em um dispositivo Android.

Eu instalei o android-ndk-r9 no seguinte local com o caminho para o compilador:

/opt/ndk/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin

arm-linux-androideabi-addr2line
arm-linux-androideabi-ar
arm-linux-androideabi-as
arm-linux-androideabi-c++
arm-linux-androideabi-c++filt
arm-linux-androideabi-cpp
arm-linux-androideabi-elfedit

arm-linux-androideabi-readelf
arm-linux-androideabi-run
arm-linux-androideabi-size
arm-linux-androideabi-strings
arm-linux-androideabi-strip

Meu arquivo de compilação cruzada é:

include(CMakeForceCompiler)

set(toolchain_path /opt/ndk/toolchains)

# Target system
set(CMAKE_SYSTEM_NAME Linux)

set(CMAKE_SYSTEM_PROCESSOR arm)

set(CMAKE_SYSTEM_VERSION 1)

# Compiler to build for the target
set(CMAKE_C_COMPILER /opt/ndk/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc)

set(CMAKE_FIND_ROOT_PATH /opt/ndk/toolchains)

Eu corro isso do meu diretório build / debug com o meu toolchain no diretório raiz.

[ant@localhost debug]$ cmake -DCMAKE_TOOLCHAIN_FILE=arm-eabi-gcc.cmake ../..
