ubuntu make 显示完整命令

Question

我正在尝试在 ubuntu 上交叉编译 libmp3lame，但在某些时候它失败了，错误日志被截断了，所以我无法真正检测到发生了什么

shell 输出的最后几行是：

/bin/bash ../libtool  --tag=CC   --mode=link /home/rafa/Desktop/missao/ndk17/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc  -mfloat-abi=softfp -marm -march=armv7-a -Os -O3   -I/home/rafa/Desktop/m2/build_dir/include -I/home/rafa/Desktop/missao/ndk17/sysroot/usr/include -I/home/rafa/Desktop/missao/ndk17/sysroot/usr/include/arm-linux-androideabi/ -L/home/rafa/Desktop/m2/build_dir/lib -L/home/rafa/Desktop/missao/ndk17/platforms/android-27/arch-arm/usr/lib -L/home/rafa/Desktop/missao/ndk17/sysroot/usr/lib/arm-linux-androideabi -fPIE       -L/home/rafa/Desktop/m2/build_dir/lib -L/home/rafa/Desktop/missao/ndk17/platforms/android-27/arch-arm/usr/lib -L/home/rafa/Desktop/missao/ndk17/sysroot/usr/lib/arm-linux-androideabi -fPIE -pie   -static  -o lame lame_main.o main.o brhist.o console.o get_audio.o lametime.o parse.o timestatus.o ../libmp3lame/libmp3lame.la -lm

我如何强制 make 显示完整的命令而不是 /../ 来帮助我了解发生了什么

=================== 更新========================

试图弄清楚它是一个非常长的脚本来构建 ffmpeg 到 android[编译 libmp3lame 失败

我会尝试粘贴相关字段：

export NDK=/home/rafa/Desktop/missao/ndk17

OS="linux-x86_64"
ARM_SYSROOT=$NDK/platforms/android-27/arch-arm
ARM_PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/$OS

CPU=armv7-a
ARCH=arm
OPTIMIZE_CFLAGS="-mfloat-abi=softfp -mfpu=neon -marm -mtune=cortex-a8 -march=$CPU -Os -O3"
ADDITIONAL_CONFIGURE_FLAG="--enable-neon "
SYSROOT=$ARM_SYSROOT
HOST=arm-linux-androideabi
CROSS_PREFIX=$ARM_PREBUILT/bin/$HOST-
OPTIMIZE_CFLAGS="$OPTIMIZE_CFLAGS "
PREBUILT=$ARM_PREBUILT

TOOLCHAIN=$NDK/sysroot/usr/include/$HOST/
export PKG_CONFIG_PATH="$PREFIX/lib/pkgconfig"
export CPP="${CROSS_PREFIX}cpp"
export CXX="${CROSS_PREFIX}g++"
export CC="${CROSS_PREFIX}gcc"
export LD="${CROSS_PREFIX}ld"
export AR="${CROSS_PREFIX}ar"
export NM="${CROSS_PREFIX}nm"
export RANLIB="${CROSS_PREFIX}ranlib"
export LDFLAGS="-L$PREFIX/lib -L$SYSROOT/usr/lib -L$NDK/sysroot/usr/lib/$HOST -fPIE -pie "
export CFLAGS="$OPTIMIZE_CFLAGS -I$PREFIX/include -I$NDK/sysroot/usr/include -I$TOOLCHAIN -L$PREFIX/lib -L$SYSROOT/usr/lib -L$NDK/sysroot/usr/lib/$HOST -fPIE " 
export CXXFLAGS="$CFLAGS "
export CPPFLAGS="-I$PREFIX/include -I$NDK/sysroot/usr/include -I$TOOLCHAIN --sysroot=$SYSROOT "
export STRIP=${CROSS_PREFIX}strip
export PATH="$PATH:$PREFIX/bin:$NDK/build"

命令：

pushd lame
./configure \
    --prefix=$PREFIX \
    --host=$HOST \
    --enable-static \
    --disable-shared \
    --with-sysroot=/home/rafa/Desktop/missao/ndk17/platforms/android-27/arch-arm/usr/lib

make clean
make  
make install
popd

它要查找的文件在

下

/home/rafa/Desktop/missao/ndk17/platforms/android-27/arch-arm/usr/lib

但我在 sysroot 和 LDFLAGS 上设置了这个目录，但它仍然找不到它

在测试了几种配置后，我找到了一种有效的方法，分享如果有人遇到类似问题

       export NDK=/home/rafa/Desktop/missao/ndk17

       OS="linux-x86_64"
       ARM_SYSROOT=$NDK/platforms/android-27/arch-arm
       ARM_PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/$OS

       CPU=armv7-a
       ARCH=arm
       OPTIMIZE_CFLAGS="-mfloat-abi=softfp -mfpu=neon -marm -mtune=cortex-a8 -march=$CPU -Os -O3"
       ADDITIONAL_CONFIGURE_FLAG="--enable-neon "
       SYSROOT=$ARM_SYSROOT
       HOST=arm-linux-androideabi
       CROSS_PREFIX=$ARM_PREBUILT/bin/$HOST-
       OPTIMIZE_CFLAGS="$OPTIMIZE_CFLAGS "
       PREBUILT=$ARM_PREBUILT
       export PKG_CONFIG_PATH="$PREFIX/lib/pkgconfig"
       export CPP="${CROSS_PREFIX}cpp"
       export CXX="${CROSS_PREFIX}g++"
       export CC="${CROSS_PREFIX}gcc"
       export LD="${CROSS_PREFIX}ld"
       export AR="${CROSS_PREFIX}ar"
       export NM="${CROSS_PREFIX}nm"
       export RANLIB="${CROSS_PREFIX}ranlib"
       export LDFLAGS="-L$PREFIX/lib -L$SYSROOT/usr/lib -L$NDK/sysroot/usr/lib/$HOST -fPIE -pie --sysroot=$SYSROOT "
       export CFLAGS="$OPTIMIZE_CFLAGS -I$PREFIX/include -I$NDK/sysroot/usr/include -I$TOOLCHAIN -fPIE " 
       export CXXFLAGS="$CFLAGS "
       export CPPFLAGS="-I$PREFIX/include -I$NDK/sysroot/usr/include -I$TOOLCHAIN --sysroot=$SYSROOT "
       export STRIP=${CROSS_PREFIX}strip
       export PATH="$PATH:$PREFIX/bin:$NDK/build"

和运行：

pushd lame
./configure \
    --prefix=$PREFIX \
    --host=$HOST \
    --enable-static \
    --disable-shared \
    --disable-frontend \ #I just need the libraries
    --with-sysroot=$SYSROOT
make clean
make  
make install
popd
