Error compiling protoc-gen-chpl.cc #6

Closed Aniket21mathur closed 4 years ago

hey @squidfunk, great work on protobluff!

I am trying to build a plugin of my own for a new language taking your code as a base. I am facing a problem in compiling protoc-gen-chpl.cc to generate protoc-gen-chpl which I can pass to the protoc compiler.

I am doing something like- g++ -I. protoc-gen-chpl.cc -lprotobuf -lpthread

but I am getting this error --->

/tmp/ccAq1MTE.o: In function `main':
protoc-gen-chpl.cc:(.text+0x3c): undefined reference to `google::protobuf::compiler::PluginMain(int, char**, google::protobuf::compiler::CodeGenerator const*)'

I think I am not doing the linking properly, but I am not able to figure out what I am missing. It would be great if you give your opinions.

Thanks!

That's a good question. It seems like it's more related to linking protobuf and not this project in particular. As this project does the same, you can just check how it is done in the respective Makefile. Note, that it uses Automake, though.

I'm closing this issue, as it's not an issue or feature that is related to this project.

Thanks for your help @squidfunk :-), I was missing the lprotoc flag, which I figured out after going through the Makefile.
