Description

系统 Mac OS TD版本: 3.2.1.0 go版本: 1.20.1 集成了TD原生链接: "github.com/taosdata/driver-go/v3/taosSql" 交叉编译命令(Linux) CGO_ENABLED=1 GOOS=linux GOARCH=amd64 CC=x86_64-linux-musl-gcc go build -o $AppName -a -ldflags "-w -s -X main.BuildVersion=${BuildVersion} -X main.CommitID=${CommitID} -X main.BuildTime=${BuildTime}" 使用交叉编译的时候，一直报 /usr/local/Cellar/musl-cross/0.9.9_2/libexec/bin/../lib/gcc/x86_64-linux-musl/9.2.0/../../../../x86_64-linux-musl/bin/ld: cannot find -ltaos

Research direction
Investigate why the linker cannot find ' ltaos' during cross compilation. Check if the TDengine library (libtaos) is being compiled for the target architecture (linux/amd64). Look at the build process in the repository, particularly the CGO LDFLAGS or any pre built library paths. The error indicates that the library is missing for the cross compilation target. Consider whether the user needs to provide a cross compiled libtaos or set the correct search path.
