protoc fails to find google/protobuf/duration.proto when building types #66

Closed saman3d closed 3 months ago

when running cargo check in wkt-types this error occurs:

protoc can't find google protobuf includes although i have them in /usr/local/include

saman3d commented 3 months ago

there was a problem with my protoc executable. in order for protoc to find includes it must be present in it's parent directory. for example: if protoc is in: /usr/local/bin/protoc includes directory must be in: /usr/local/includes

Good to hear you found the solution @saman3d! I will check if I can add this tip to the readme so if it happens to someone else they will know what to do.

Had same issue and had to copy proto includes. Thanks @saman3d. One correction though:

includes directory must be in: /usr/local/includes

to

includes directory must be in: /usr/local/include
