您好，我正在尝试按照步骤guid来构建jpeg xl（我在Windows上并尝试为Linux构建x64版本）
之后：
docker run -u root:root -it --rm -v C:\Users\fred\source\tools\jpegxl\jpeg-xl-master -w /jpeg-xl gcr.io/jpegxl/jpegxl-builder
我正在运行容器，但是我不知道如何在其中运行命令：
CC=clang-6.0 CXX=clang++-6.0 ./ci.sh opt
我尝试使用CC = clang-6.0 CXX = clang ++-6.0 ./ci.sh opt，我得到 ./ ci.sh：没有这样的文件或目录 “ ls”什么也没显示
有人知道如何构建它吗？

确保在容器内启动bash终端：
[[3, 3], [2, 2], [1, 1], [3, 2], [3, 1], [2, 1], [1, 2], [1, 3], [2, 3]]

命令中缺少docker run -it <image> /bin/bash
。结果，您正在自己的环境（而不是容器）内执行clang的命令。
答案 1 :(得分：0)
您可以使用-e
示例
-e CC=clang-6.0 -e CXX=clang++-6.0
登录到容器的完整命令：
docker run -u root:root -it --rm -e CC=clang-6.0 -e CXX=clang++-6.0 -v C:\Users\fred\source\tools\jpegxl\jpeg-xl-master -w /jpeg-xl gcr.io/jpegxl/jpegxl-builder /bin/bash
答案 2 :(得分：0)
他们在不更新命令的情况下更新了图像，因此命令为
CC=clang-7 CXX=clang++-7 ./ci.sh opt
此处为争议： Can't build from docker image "Unknown clang version"
