Question

我使用ndk-10e编译qemu2.5.0。我已经成功编译了glib for android。我的configure命令是：

PKG_CONFIG_PATH="$SYSROOT/usr/lib/pkgconfig" ./configure -- 
prefix="$SYSROOT/usr" --target-list=arm-linux-user --disable-system -- 
disable-bsd-user --disable-tools --disable-zlib-test --cross- 
prefix="arm-linux-androideabi-" --cc="$NDK/toolchains/arm-linux- 
androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc" - 
-host-cc="$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux- 
x86_64/bin/arm-linux-androideabi-gcc" --cpu="arm" -- 
cxx="$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux- 
x86_64/bin/arm-linux-androideabi-g++" --extra-ldflags="-fPIE -pie -- 
sysroot $SYSROOT -L$NDK/toolchains/arm-linux-androideabi- 
4.9/prebuilt/linux-x86_64/lib/gcc/arm-linux-androideabi/4.9/ - 
L$NDK/sources/cxx-stl/gnu-libstdc++/4.9/libs/armeabi/ - 
L$NDK/platforms/android-21/arch-arm/usr/lib" --extra-cflags="-fPIE - 
pie --sysroot $SYSROOT -I$NDK/sources/cxx-stl/gnu- 
libstdc++/4.9/include -I$NDK/sources/cxx-stl/gnu- 
libstdc++/4.9/libs/armeabi/include -L$NDK/sources/cxx-stl/gnu- 
libstdc++/4.9/libs/armeabi/" --disable-guest-agent

当我输入＆＃34; make＆＃34;时，它会给我这个错误。

Answer 1

这将是以下的混合物：

2.5是QEMU的旧版本;你可能会遇到编译中的错误与更新/不同版本的libc已经修复上游。首先使用更新的版本。
您正在构建针对Android libc（仿生）的构建，它不是经过测试或支持的libc构建的。与glibc（标准Linux libc）相比，它存在差异或特质，你需要改变QEMU来解决这些问题。

例如，关于__key的错误，问题是Bionic在struct ipc_perm＆＃34; key＆＃34;中命名了该字段的版本，而不是＆＃34; __ key＆＃34;。
