Qt Creator error : --proto_path
-
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.
