页: 1 -- check=my_file.cu 我拿着这些内容(简化):
I[13:05:09.356] Testing on source file /path/to/my_file.cu

I[13:05:09.363] Loaded compilation database from /path/to/build/compile_commands.json
I[13:05:09.364] Compile command from CDB is: /path/to/bin/nvcc [...] -isystem=/path/to/lib/include [...] -- /path/to/my_file.cu

I[13:05:09.364] Parsing command...
I[13:05:09.371] internal (cc1) args are: -cc1 [...] -isystem =/path/to/lib/include [...] -x cuda /path/to/my_file.cu
关键是,汇编数据库中的指挥与平级内部指挥之间存在差异。 姓名:-isystem=/path/to/lib/include =/path/to/lib/include(有空间)。 看来部族没有适当划分“=syntax”这一系统。
Clangd is then unable to find the includes for libs installed system-wide unless I manually add -I /path/to/lib/include with the clangd config file.
表格-isystem=/path/to/lib/include正在由编集指挥部的CMake生成,并在与NVCC/GCC进行汇编时进行罚款。 但是,部族似乎将这一条解释为:<代码>=/path/to/lib/include。 而不是/path/to/lib/include。
This is with C++/CUDA libraries, but I don t think that is the root cause.
是否有办法让部族适当打平-isystem为NVCC开的CMake所产生的旗帜? 这是否与部族的预期行为一致?

如您所见,《世界人权宣言》的《守则》中有<条码>-isystem=......具体规定的制度。
注:这有CMake 3.24.3和NVCCcuda_12.2.r12.2/compiler.33191640_0。
