对于 Bazel,我正在从我的内部拉入一个外部库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",
],
)
问题是它找不到#include <SDL.h>
。
我尝试将其添加到 copts:
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。如果我尝试将其添加includes
到cc_library
.
我尝试了另一个技巧,我看到你通过 Bazel 中的另一个 repo 使标题可见,编辑WORKSPACE
如下:
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 作为我正在尝试构建的外部库的 deps 引用,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。它来自我下拉的外部库。
我该怎么办?
我不明白为什么我不能向 copts 添加系统路径(可能是密封的原因)。我不知道如何包含路径并将它们作为系统头文件访问。我也尝试了不同的东西-isystem
,但看到了同样的错误。
