Question

我参考了其他编译教程

configure

修改内容：

SLIBNAME_WITH_MAJOR='$(SLIBNAME).$(LIBMAJOR)'

LIB_INSTALL_EXTRA_CMD='$$(RANLIB)"$(LIBDIR)/$(LIBNAME)"'

SLIB_INSTALL_NAME='$(SLIBNAME_WITH_VERSION)'

SLIB_INSTALL_LINKS='$(SLIBNAME_WITH_MAJOR)$(SLIBNAME)'

替换：

SLIBNAME_WITH_MAJOR='$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)'

LIB_INSTALL_EXTRA_CMD='$$(RANLIB)"$(LIBDIR)/$(LIBNAME)"'

SLIB_INSTALL_NAME='$(SLIBNAME_WITH_MAJOR)'

SLIB_INSTALL_LINKS='$(SLIBNAME)'

构建结果：
libavdevice-55.so ...

build_android.sh

NDK=/home/dennis/android-ndk-r9d
SYSROOT=$NDK/platforms/android-9/arch-arm/ 
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64 
enter code here
function build_one
{
./configure \  
--prefix=$PREFIX \
--enable-shared \  
--disable-static \ 
--disable-doc \  
--disable-ffserver \ 
--enable-cross-compile \  
--cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \ 
--target-os=linux \ 
--arch=arm \ 
--sysroot=$SYSROOT \  
--extra-cflags="-Os -fpic $ADDI_CFLAGS" \  
--extra-ldflags="$ADDI_LDFLAGS" \  
$ADDITIONAL_CONFIGURE_FLAG  
} 
CPU=arm  
PREFIX=$(pwd)/android/$CPU  
ADDI_CFLAGS="-marm"  
build_one

我想删除版本号结果：
libavdevice.so ...

Answer 1

无需更改config.mak

只需更改

--target-os=linux

带

--target-os=android

我的例子：

NDK=${HOME}/android-sdk-linux/ndk-bundle
ABI=arm

./configure \
    --arch=$ABI \
    --target-os=android \
    --disable-everything \
    --disable-symver \
    --enable-runtime-cpudetect \
    --enable-pic \
    --enable-shared \
    --disable-static \
    --prefix=../build/$ABI \
    --cross-prefix=$NDK/toolchains/$ABI-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/$ABI-linux-androideabi- \
    --sysroot=$NDK/platforms/android-26/arch-$ABI \
    --extra-cflags="-march=armv7-a -mfloat-abi=softfp -fPIC -DANDROID" \
    --extra-ldflags="" \
    || exit 1

    make clean
    make -j4 || exit 1
    make install || exit 1

Answer 2

./configure中的

：

SLIBNAME_WITH_MAJOR='$(SLIBPREF)$(FULLNAME)$(SLIBSUF)'

<{1>}中的

：更改行

./library.mak

与

$(SUBDIR)$(SLIBNAME): $(SUBDIR)$(SLIBNAME_WITH_MAJOR)
