如何让 Wireguard-Android make 文件在 Windows 上运行？

Question

我正在尝试在我的 windows machine 上构建 wireguard-android 源代码，通过反复试验逐步解决问题。

我安装了CMake和Make，我遇到的第一个问题是uname（mingw64）报告的'bad'值，与[=托管的golang filenames不匹配57=].

我编辑（破解）了 make 文件以指向 windows 版本 (amd64) 的真实文件名。问题是 windows 版本有一个 .zip 扩展名而不是 .tar.gz 并且 zip 的结果似乎与管道命令不兼容。

原命令:

curl "https://dl.google.com/go/go$(DESIRED_GO_VERSION).$(shell uname -s | tr '[:upper:]' '[:lower:]')-$(NDK_GO_ARCH_MAP_$(shell uname -m)).tar.gz" | tar -C "$(dir $@)" --strip-components=1 -xzf -

我尝试的更改：（使用 if-else 因为它仍然需要在 mac 上运行）

ifeq "msys" "$(shell uname -o | tr '[:upper:]' '[:lower:]')"
    # Note: when enclosed in the ifeq, the ARCH_MAP part no longer worked
    # Note: using tar with the zip fails, because we cant untar a zip (signal 13)
    # Note: using unzip with the zip fails with confusing paths
    curl "https://dl.google.com/go/go$(DESIRED_GO_VERSION).windows-amd64.zip" | unzip -C "$(dir $@)" --strip-components=1 -xzf -
else
    curl "https://dl.google.com/go/go$(DESIRED_GO_VERSION).$(shell uname -s | tr '[:upper:]' '[:lower:]')-$(NDK_GO_ARCH_MAP_$(shell uname -m)).tar.gz" | tar -C "$(dir $@)" --strip-components=1 -xzf -
endif

如果使用解压会出现错误:

unzip: cannot find or open C:\wireguard-android\app\build\intermediates\cmake\debug\obj\armeabi-v7a/../generated-src/go-1.13.7/, C:\wireguard-android\app\build\intermediates\cmake\debug\obj\armeabi-v7a/../generated-src/go-1.13.7/.zip or C:\wireguard-android\app\build\intermediates\cmake\debug\obj\armeabi-v7a/../generated-src/go-1.13.7/.ZIP.

make: *** [C:\wireguard-android\app\build\intermediates\cmake\debug\obj\armeabi-v7a/../generated-src/go-1.13.7/.prepared] Error 9

如果使用tar会导致错误：

curl "https://dl.google.com/go/go1.13.7.windows-amd64.zip" | tar -C "C:\wireguard-android\app\build\intermediates\cmake\debug\obj\armeabi-v7a/../generated-src/go-1.13.7/" --strip-components=1 -xzf -

make: *** [C:\wireguard-android\app\build\intermediates\cmake\debug\obj\armeabi-v7a/../generated-src/go-1.13.7/.prepared] Error 2

我应该如何让这个命令起作用？（使用 tar 或 zip/unzip）
有人向我指出，也许我需要 Android 发行版，而不是 Windows 发行版。在那种情况下，我假设我需要 armeabi-v7a，但我只能看到 ARMv6 和 ARMv8 包。我应该使用什么发行版？

我已经设法解决了这个问题，我正在回答我自己的问题而不是删除，因为我认为这最终会帮助其他开发者。

首先说明一下:

您似乎应该包括目标平台 Go 库（即 Android 的 ARM），但如果您尝试这样做，您将在构建时收到文件不可执行的错误。（因此构建平台是要匹配的版本，即这里的Windows）
因为 Google 以 Zip 格式提供 Windows 库（相对于其他平台的 tar.gz），您不能使用 tar 命令。
- 因为无法从 curl 流中读取 zip（索引位于文件末尾），您需要下载文件然后解压缩。有些人建议使用 jar 命令，但是这在 cmake/make
- zip 文件将被解压缩到您选择的任何路径内的子目录 'go' 中。为此，您需要修改路径
Windows 上的某些命令不接受 .. 作为路径的中间，因此我不得不修改 CMakeLists 文件以使用绝对路径

Makefile 的更改结尾：（从 .prepared/mkdir 语句之后开始）

# Warning the (lack-of) indentation here is critical 
# Note: I've hardcoded the windows filename below, so you'll need to do an `if` (like in my question) if you want to support other platforms as well

    curl -o "$(BUILDDIR)/go-$(DESIRED_GO_VERSION)/gofile.zip" "https://dl.google.com/go/go$(DESIRED_GO_VERSION).windows-amd64.zip"
    unzip -o "$(BUILDDIR)/go-$(DESIRED_GO_VERSION)/gofile.zip" -d "$(dir $@)"
    rm -f "$(BUILDDIR)/go-$(DESIRED_GO_VERSION)/gofile.zip"

    patch -p1 -f -N -r- -d "$(dir $@)go/" < goruntime-boottime-over-monotonic.diff
    touch "$@"

$(DESTDIR)/libwg-go.so: export PATH := $(BUILDDIR)/go-$(DESIRED_GO_VERSION)/go/bin/:$(PATH)
$(DESTDIR)/libwg-go.so: $(BUILDDIR)/go-$(DESIRED_GO_VERSION)/.prepared go.mod
    go build -tags linux -ldflags="-X golang.zx2c4.com/wireguard/ipc.socketDirectory=/data/data/$(ANDROID_PACKAGE_NAME)/cache/wireguard" -v -trimpath -o "$@" -buildmode c-shared

CMakeLists 文件的更改结尾：（替换add_custom_target部分）

# added a new variable to get the parent dir without using .. in the path
get_filename_component(destdirparent "${CMAKE_LIBRARY_OUTPUT_DIRECTORY}/.." ABSOLUTE)

# referred to the variable on the last line of this statment
add_custom_target(libwg-go.so WORKING_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}/libwg-go" COMMENT "Building wireguard-go" VERBATIM COMMAND make

    LDFLAGS=${CMAKE_SHARED_LINKER_FLAGS}\ -fuse-ld=gold
    DESTDIR=${CMAKE_LIBRARY_OUTPUT_DIRECTORY}
    BUILDDIR=${destdirparent}/generated-src
    )

感谢@Nick Cardoso 的回答。经过反复的修改和调试，我成功的搞定了Windows平台上可用的makefile和CMakeLists.txt

使用时只需要修改这三个变量：GIT_BIN_PATH、DESIRED_GO_VERSION、MAKE_PATH。备注：

项目路径中不能有空格！否则CURDIR的路径会被截断
不要安装 Cygwin！您只需要 Git 和 NDK，因为 Git 包含所需的命令：unzip.exe， patch.exe 和 touch.exe
