Tre*_*key 8 c++ sdl bazel imgui
对于 Bazel,我正在从我的内部引入一个外部库WORKSPACE:
new_http_archive(
name = "imgui",
build_file = "deps/BUILD.imgui",
sha256 = "c457fdc19b4e3aa74deccf6a2d9bc51f0d470b3acd9cc095bf04df16459d6474",
strip_prefix = 'imgui-1.62',
url = "https://github.com/ocornut/imgui/archive/v1.62.tar.gz",
)

在里面BUILD.imgui,我正在尝试构建它:
cc_library(
name = "imgui_sdl_opengl3",
linkopts = ["-ldl", "-lGL", "-L/usr/lib/x86_64-linux-gnu", "-lSDL2", "-lSDL"],
copts = ["-Iexamples/", "-D_REENTRANT",],
includes = [".","examples/libs/gl3w"],
hdrs = [
"examples/imgui_impl_opengl3.h",
"examples/libs/gl3w/GL/gl3w.h",
"examples/imgui_impl_sdl.h",
"examples/libs/gl3w/GL/glcorearb.h",
],
srcs = [
"examples/imgui_impl_opengl3.cpp",
"examples/imgui_impl_sdl.cpp",
"examples/libs/gl3w/GL/gl3w.c",
],
)

问题是找不到#include <SDL.h>。
我尝试将其添加到科普特:
copts = ["-Iexamples/", "-D_REENTRANT", "-I/usr/include/SDL"],

但错误是:
The include path '/usr/include/SDL' references a path outside of the execution root.

好的。同样的,如果我尝试将其添加到includes的参数cc_library。
我尝试了另一个技巧,我看到您通过 Bazel 中的另一个存储库显示标题WORKSPACE,如下所示:
new_local_repository(
name = "SDL",
path = "/usr/include/SDL",
build_file_content = """
package(
default_visibility = [
"//visibility:public",
],
)
cc_library(
name = "headers",
srcs = glob(["**/*.h"]),
)
""",

问题是,如果我将该 repo 作为 deps 引用到我尝试构建的外部库,我会收到以下错误:
external/imgui/examples/imgui_impl_sdl.cpp:38:10: error: 'SDL.h' file not found with <angled> include; use "quotes" instead
#include <SDL.h>
^~~~~~~
"SDL.h"

当然,我不能将标题更改为那个,因为它不是我的标题。它来自我拉下来的外部库。
我该怎么办?
我不明白为什么我不能向 copt 添加系统路径(可能是密封原因)。我不知道如何包含路径并将它们作为系统标头访问。我也尝试了不同的东西-isystem,但看到了相同的错误。
正如 L\xc3\xa1szl\xc3\xb3 所说,您可以将 设置includes为当前目录,这将允许在其他代码中用作依赖项时将其检测为系统标头:
cc_library(\n ... \n includes = [\n ".",\n ],\n)\nRun Code Online (Sandbox Code Playgroud)\n
