To build C interoperability projects in Cangjie, compile C code into shared or static libraries, then link them with Cangjie code using the `cjc` compiler flags `-L` for library paths and `-l` for linking, following platform-specific naming conventions for Linux, macOS, and Windows.

Configuring FFI dependencies in `cjpm.toml` involves specifying library paths and linking options within the configuration file, enabling the `cjpm` package manager to automatically resolve and build C interoperability projects alongside Cangjie source code.

Platform-specific library naming conventions for Cangjie FFI dictate distinct prefixes and suffixes for shared and static libraries across Linux, macOS, and Windows, ensuring the `cjc` compiler and `cjpm` linker can correctly locate and link the required binaries during compilation.

For security hardening in Cangjie FFI builds, apply compiler and linker flags such as `-fstack-protector-all` to protect stack memory and `-z noexecstack` to enforce non-executable stacks, mitigating potential vulnerabilities during C and Cangjie interoperability compilation.

Yes, you can compile C shared libraries and link them with Cangjie main files on Linux by executing direct shell commands to build the C code into a library, then using `cjc` with appropriate linker options to integrate it with a Cangjie main file.
