cannot compile on macOS Catalina #2

Closed singlepig closed 4 years ago

你好，我将你的这个项目clone下来以后，只修改了ndk路径，执行./build_android.sh报错。

/Users/singlepig/Library/Android/sdk/android-ndk-r20b/toolchains/llvm/prebuilt/darwin-x86_64/bin/aarch64-linux-android21-clang is unable to create an executable file.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

ndk-r20b是官网下的，解压后跟Android sdk放一起了，这个clang文件确实是存在的，ls 看过了。前段时间系统升级到Catalina，不知道是不是跟系统不兼容啊？？

config.log里有很多

clang: warning: joined argument expects additional value: '-mcpu=' [-Wunused-command-line-argument]
clang: error: the clang compiler does not support '-march=core2'

这样的报错。完整文件在这里。https://send.firefox.com/download/7442922aa51fa9e3/#tB6x0L4bwHoF47lUwHhauA

求助，不胜感激！

系统macOS 10.15.2 (19C57)

周末我试试，现在用的 Windows。

@singlepig 我试了一遍没有问题。

看你的报错 **/bin/aarch64-linux-android21-clang is unable to create an executable file. C compiler test failed.

你应该是要编译 arm64 的 so。

我添加了一个 build_android_64.sh，我试了一遍可以编译出 so，你可以看看。

$ cd Desktop/ffmpeg4.2

# 设置 build_android_64.sh 可执行权限
$ chmod +x build_android_64.sh

# configure 对 FFmpeg 进行配置
$ ./build_android_64.sh

# 编译
$ make -j 8

$ make install

@binglingziyu 非常感谢！顺便问一句，你是用的什么版本的macOS？ 我重新pull了，只改了ndk路径，我试了一下，终于，还是失败了，😂

头部的那些路径我都检查过，都存在。尾部的错误，我自己再研究一下。 之前ffmpeg一直无法编译成功，搞了三天了，要爆炸了，到现在也没搞定，实在不行了，后来上周五用docker拉ubuntu容器编，虽然慢了点，但是一把过！😂

锅找到了！是之前安装conda的时候在zshrc里加了一段官方文档里面写的shell，加了之后，我的shell环境中就多了这么些东西！

CFLAGS=-march=core2 -mtune=haswell -mssse3 -ftree-vectorize -fPIC -fPIE -fstack-protector-strong -O2 -pipe
DEBUG_CFLAGS=-march=core2 -mtune=haswell -mssse3 -ftree-vectorize -fPIC -fPIE -fstack-protector-strong -O2 -pipe -Og -g -Wall -Wextra
CXXFLAGS=-march=core2 -mtune=haswell -mssse3 -ftree-vectorize -fPIC -fPIE -fstack-protector-strong -O2 -pipe -stdlib=libc++ -fvisibility-inlines-hidden -std=c++14 -fmessage-length=0
DEBUG_CXXFLAGS=-march=core2 -mtune=haswell -mssse3 -ftree-vectorize -fPIC -fPIE -fstack-protector-strong -O2 -pipe -stdlib=libc++ -fvisibility-inlines-hidden -std=c++14 -fmessage-length=0 -Og -g -Wall -Wextra

core2的那个问题就是这么来的。 真是太坑了！ 我是看configure文件里面的test_cc()方法，

test_cc(){
    log test_cc "$@"
    cat > $TMPC
    log_file $TMPC
    echo "===="
    echo $cc
    echo $CPPFLAGS
    echo $CFLAGS
    echo $CC_C
    echo "===="
    test_cmd $cc $CPPFLAGS $CFLAGS "$@" $CC_C $(cc_o $TMPO) $TMPC
}

echo是我加的，发现用到了$CFLAGS，猜测是用的shell环境的变量，新起一个终端，env | ag "mssse3"看了一下，发现确实是这样，然后才联想到conda，注释掉conda的那段zshrc代码，发现问题解决！

反过头来看，其实应该能更早地定位到问题点的，刚开始的时候没有认真看，认真想，为啥会报不支持march=core2的原因，觉得是自己编译脚本写的有问题，现在看来，要是当时能耐心去追追configure，应该早就能解决了。 I'm so vegetable! 😂

https://docs.conda.io/projects/conda/en/latest/user-guide/install/macos.html#installing-in-silent-mode

conda init zsh会加入以下这段代码。

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/Users/singlepig/miniconda/bin/conda' 'shell.zsh' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/Users/singlepig/miniconda/etc/profile.d/conda.sh" ]; then
        . "/Users/singlepig/miniconda/etc/profile.d/conda.sh"
    else
        export PATH="/Users/singlepig/miniconda/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

就是这段代码的锅，会往你的shell里加料！！
