我正在尝试使用指令来编译一个示例Pytroch C ++项目：
httpps://pytorch.org/cppdocs/ installing.html
当我到达通话点时：
cmake -dcmake_prefix_path =/absolute/path/to/libtorch ..
CMAKE-建造。 - config发行版
我会发现一个错误：
ld: unknown option: --no-as-needed
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [BLOCK_READER] Error 1
make[1]: *** [CMakeFiles/BLOCK_READER.dir/all] Error 2
make: *** [all] Error 2
似乎问题是链接器不了解选项 - 不需要的。
经过一些研究，它看起来像是链接器的新版本支持此选项，但不支持我拥有的版本。
因此，我的问题是如何将链接器更新为支持此选项的版本？
我在Apple M1（Bigsur）上。
这是我的理解是LD是GCC的一部分，所以我可以更新GCC吗？
顺便说一句，这是我的cmake cmakelists.txt
cmake_minimum_required(VERSION 3.0 FATAL_ERROR)
project(block_reader)
# Setup Torch
set(CMAKE_CXX_COMPILER "/usr/bin/g++" CACHE STRING "C++ compiler" FORCE)
set(CMAKE_LINKER "/usr/bin/ld" CACHE STRING "" FORCE)
set(CMAKE_PREFIX_PATH /Users/username/Downloads/libtorch)
find_package(Torch REQUIRED)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${TORCH_CXX_FLAGS}")
# Setup Torch
add_executable(BLOCK_READER main.cpp)
target_include_directories(BLOCK_READER PRIVATE /src)
set_property(TARGET BLOCK_READER PROPERTY CXX_STANDARD 14)
target_link_libraries(BLOCK_READER "${TORCH_LIBRARIES}")
I am trying to compile an example pytroch c++ project using instructions at:
https://pytorch.org/cppdocs/installing.html
When i reach the point of calling:
cmake -DCMAKE_PREFIX_PATH=/absolute/path/to/libtorch ..
cmake --build . --config Release
I get an error:
ld: unknown option: --no-as-needed
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [BLOCK_READER] Error 1
make[1]: *** [CMakeFiles/BLOCK_READER.dir/all] Error 2
make: *** [all] Error 2
It looks like the issue is that the linker doesnt understand the option --no-as-needed.
After some research it looks like newer version of the linker support this option, but not the version i have.
So my question is how do i update my linker to a version that support this option?
I am on a Apple M1 (BigSur)..
It is my understanding that ld is part of gcc so can i just update gcc?
Btw here is my cmake CMakeLists.txt
cmake_minimum_required(VERSION 3.0 FATAL_ERROR)
project(block_reader)
# Setup Torch
set(CMAKE_CXX_COMPILER "/usr/bin/g++" CACHE STRING "C++ compiler" FORCE)
set(CMAKE_LINKER "/usr/bin/ld" CACHE STRING "" FORCE)
set(CMAKE_PREFIX_PATH /Users/username/Downloads/libtorch)
find_package(Torch REQUIRED)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${TORCH_CXX_FLAGS}")
# Setup Torch
add_executable(BLOCK_READER main.cpp)
target_include_directories(BLOCK_READER PRIVATE /src)
set_property(TARGET BLOCK_READER PROPERTY CXX_STANDARD 14)
target_link_libraries(BLOCK_READER "${TORCH_LIBRARIES}")

我在M3 MacBook（Sonoma）上，并在关注。当我注意到此示例命令中的链接
指向
libtorch的Linux分布时，我最终解决了此问题，这会使CMAKE混淆并导致其添加Linux Linker选项。我去Pytorch下载网站后，这个问题消失了： https://pytorch.org/cppdocs/cppdocs/installing 。ARM64版本）。I'm on an M3 MacBook (Sonoma) and encountered the same problem when following through the tutorial in https://pytorch.org/cppdocs/installing.html . I eventually solved this problem when I noticed that the link in this example command
points to a Linux distribution of
libtorch, which confuses CMake and causing it to add Linux linker options. This problem went away after I went to the PyTorch download site: https://pytorch.org/cppdocs/installing.html and downloaded the version oflibtorchthat corresponds to the correct system and the correct architecture for my system (since you're on M1, you probably want thearm64version as well).
