Hello,
Since I could not find the answer in the cgo documentation, I would really appreciate if somebody could help me to understand why when I build cgo code with calls to the shared library, the linker tries to find the shared library even though it is instructed to build dynamic binary and not static. I have C built shared library, I have no control how it gets built, I only have lib_blahblah_x64_86.so . There are 2 external functions bind_wrapper/unbind_wrapper in that library which I call from cgo. Here is the command line I use to compile: CC=/bin/tools/llvm11/llvm-11.0-p25/bin/clang-11 go build -o go_connect -linkshared -ldflags "-linkmode external -extldflags -dynamic" go_connect.go The compilation succeeds, but the linker is complaining: /tmp/go-link-2323626149/000001.o: In function `_cgo_df3b8c92b86e_Cfunc_bind_wrapper': /tmp/go-build/cgo-gcc-prolog:68: undefined reference to `bind_wrapper' /tmp/go-link-2323626149/000001.o: In function `_cgo_df3b8c92b86e_Cfunc_unbind_wrapper': /tmp/go-build/cgo-gcc-prolog:87: undefined reference to `unbind_wrapper' clang-11: error: linker command failed with exit code 1 (use -v to see invocation) My expectation was that the linker will not check external references to these functions while building the binary, and only when the binary is executed, the dynamic linker will attempt to resolve them. I am suspecting I got something wrong, appreciate if somebody could provide some suggestions.
