New issue 673 by weegreen...@gmail.com: protoc: can't control output
directory
https://code.google.com/p/protobuf/issues/detail?id=673
I am working on integrating the protoc compiler to my build system, however
I'm finding it difficult to control where the output files are saved.
What steps will reproduce the problem?
1. unzip project
2. change directories
$ cd protobuf_bug
3. execute expected use case:
$ protoc --cpp_out=src/audacity/messages/pb
src/audacity/messages/pb/Type.proto
4. observe output files not placed in specified output directory:
$ find .
.
./src
./src/audacity
./src/audacity/messages
./src/audacity/messages/pb
./src/audacity/messages/pb/src
./src/audacity/messages/pb/src/audacity
./src/audacity/messages/pb/src/audacity/messages
./src/audacity/messages/pb/src/audacity/messages/pb
./src/audacity/messages/pb/src/audacity/messages/pb/Type.pb.h
./src/audacity/messages/pb/src/audacity/messages/pb/Type.pb.cc
./src/audacity/messages/pb/Type.proto
5. clean up the mess
$ rm -rf src/audacity/messages/pb/src
6. execute next expected use case:
$ protoc --cpp_out=. src/audacity/messages/pb/Type.proto
7. observe correct output:
$ find .
.
./src
./src/audacity
./src/audacity/messages
./src/audacity/messages/pb
./src/audacity/messages/pb/Type.pb.h
./src/audacity/messages/pb/Type.pb.cc
./src/audacity/messages/pb/Type.proto
What is the expected output? What do you see instead?
I expect the generated files to be placed in the directory specified,
instead funny path manipulation is occurring.
What version of the product are you using? On what operating system?
$ protoc --version
libprotoc 2.5.0
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.1 LTS
Release: 14.04
Codename: trusty
Please provide any additional information below.
Please add some option to explicitly place the generated files to
specified location, similar to how gcc -o works, as protoc is advertised as
a compiler.
The location where protoc places output files isn't explained in the
documentation, if the default is to always place the output files next to
the .proto file, then there should be a set of --cpp, --python, --java
switches which does this, rather some --XXX_out=DIR switch.
