Can CGO Directives Include C/C Files from Subdirectories?

Compiling C Files from Subdirectories in Go Build with CGO Directives

Go build with CGO directives seamlessly includes C/C files in the package's root during compilation. However, a common question arises: is there a method to incorporate C/C files from specific subdirectories into the compilation alongside those present in the root using CGO directives?

Can CGO Directives Involve Subdirectory C Files?

Unfortunately, the direct answer is no. CGO directives do not inherently allow for the inclusion of C/C files from subdirectories. The only option is to treat the subdirectory as a distinct Go package.

Alternative Approach

To effectively incorporate C/C files from subdirectories, you need to consider treating the subdirectory as a separate Go package. This involves creating appropriate Go functions that expose the desired functionality and importing these functions into your project.

Complexity Considerations

It's important to note that compiling C/C files through CGO directives is primarily intended for straightforward requirements. More intricate setups may necessitate separate compilation and precise CGO directives for linking purposes. The Go toolchain's capabilities are limited as a comprehensive build tool.
