How can I use C-Go bindings in a different module/directory than the one I built them in?
问题
我正在使用这些绑定。
根据文档，我执行以下命令：
git clone --recurse-submodules https://github.com/go-skynet/go-llama.cpp
cd go-llama.cpp
make libbinding.a
然后，在go-llama.cpp的子目录中运行示例脚本或任何其他脚本，可以使用以下命令成功运行：
LIBRARY_PATH=$PWD C_INCLUDE_PATH=$PWD go run ./examples -m "/model/path/here" -t 14
然而，当我尝试从不同的目录使用这些绑定时遇到了问题。
假设我有以下项目布局：
ParentDir \
--- go-llama.cpp \
--- --- <go-llama.cpp的内容>
--- project \
--- --- <引用绑定的Go代码>
如果我尝试在project目录中运行代码，会出现编译错误，找不到common.h。
我尝试过更改编译器标志（我怀疑你必须这样做），例如将=$PWD更改为=$(pwd)../go-llama.cpp，或者使用绝对路径~/tes/go-llama.cpp等。
我认为我的编译器标志没问题，因为当我在go-llama.cpp的更深层次的目录中更改标志以指向主go-llama.cpp目录时，我能够成功编译。
英文:
I'm using these bindings.
As per the docs, I
git clone --recurse-submodules https://github.com/go-skynet/go-llama.cpp
cd go-llama.cpp
make libbinding.a
and then running the example script, or any other script in a sub direcotory of go-llama.cpp works just fine with a command structured like:
LIBRARY_PATH=$PWD C_INCLUDE_PATH=$PWD go run ./examples -m "/model/path/here" -t 14
However, I run into problems trying to use these bindings from a different dir.
Say I have the following project layout:
ParentDir \
--- go-llama.cpp \
--- --- <go-llama.cpp contents>
--- project \
--- --- <Go code which references bindings>
If I try to run code in the project dir, I get a compilation error, common.h can't be found.
I've messed around with changing the compiler flags (which i suspect you have to do) like =$PWD to =$(pwd)../go-llama.cpp, and absolute ~/tes/go-llama.cpp, etc.
I think my compiler flags are fine, because I'm able to compile when testing with an even-more-nested dir within go-llama.cpp if I change the flags to point to the main go-llama.cpp dir from the relative location deep within the dirs.

我认为这是因为你没有从克隆的路径引用github.com/go-skynet/go-llama.cpp - 当go工具下载该包到$GOPATH/pkg/mod时，并没有执行--recurse-submodules操作。
你可以通过在项目中运行以下命令来查看该模块的路径：
go list -m -f '{{.Dir}}' github.com/go-skynet/go-llama.cpp
这应该会显示类似于以下内容：
$GOPATH/pkg/mod/github.com/go-skynet/go-llama.cpp@v0.0.0-20230509080828-f4d26f43f1d3
如果你在该目录中查看，你会发现llama.cpp目录（以及其下的examples目录）不存在。
你可以通过在项目目录中运行以下命令，编辑你的项目go.mod文件，将其引用到你本地克隆的go-llama.cpp存储库：
go mod edit -replace=github.com/go-skynet/go-llama.cpp=../go-llama.cpp/
我还没有尝试运行，因为我还没有下载模型，但是（在运行了go mod edit命令之后），我可以成功地使用以下命令构建代码：
go build
希望对你有帮助。
英文:
I think this is because you're not referencing github.com/go-skynet/go-llama.cpp from the path you cloned – the go tool has downloaded the package into $GOPATH/pkg/mod but not done the --recurse-submodules thing when it did that.
You can see the path being used for that module by running the following command from your project:
go list -m -f '{{.Dir}}' github.com/go-skynet/go-llama.cpp
That should show something like
$GOPATH/pkg/mod/github.com/go-skynet/go-llama.cpp@v0.0.0-20230509080828-f4d26f43f1d3
If you look in that directory, you'll see the llama.cpp directory (and examples directory under it) are not there.
You can edit your project go.mod to reference your locally-cloned copy of the go-llama.cpp repo by running the following command from your project directory:
go mod edit -replace=github.com/go-skynet/go-llama.cpp=../go-llama.cpp/
I haven't tried running as I haven't downloaded a model, but (after running that go mod edit command) I'm able to successfully build the code using just:
go build
