Qt Creator error : --proto_path
-
Error Message I received
File does not reside within any path specified using --proto_path (or -I). You must specify a --proto_path which encompasses this file. Note that the proto_path must be an exact prefix of the .proto file names -- protoc is too dumb to figure out when two paths (e.g. absolute and relative) are equivalent (it's harder than you think).

Hi,
You have to provide more context.

Trying to make a project with the Mingw32 toolkit and when I tried to build it with Qtcreator I get the following error message
../../ostinato/common/protocol.proto: File does not reside within any path specified using --proto_path (or -I). You must specify a --proto_path which encompasses this file. Note that the proto_path must be an exact prefix of the .proto file names -- protoc is too dumb to figure out when two paths (e.g. absolute and relative) are equivalent (it's harder than you think). -
Again: please provide more context.
What project is that ?
What OS are you working on ?
What version of Qt are you using ?
What version of Qt Creator are you using ?
What version of protobuf are you using ?
etc. -
It sounds to me like you are trying to compile a Google Protocol Buffer file.
This can be done using the Qt pro file with an extra compiler options.
For example in your project file add something like this:PROTOC_DIR = "C:\protoc-3.6.1-win32\bin" PROTOS_DIR = $$PWD PROTOS = AxisMessage.proto message ("Protobuf Compiler for $${PROTOS}") gprotoc.name = protobuf_headers gprotoc.target = $$PWD/AxisMessage.pb.cc gprotoc.depends = FORCE gprotoc.variable_out = SOURCES gprotoc.commands = $$PROTOC_DIR\protoc --cpp_out=$$PWD --proto_path=$$PWD $$PROTOS gprotoc.CONFIG += no_link target_predeps PRE_TARGETDEPS = $$PWD/AxisMessage.pb.cc QMAKE_EXTRA_TARGETS += gprotocIf this is a CMAKE project, then I'm not sure what you do.

Try replacing the . by $$PWD in the protobuff pri file.
