logging.cpp causing build error

[systemshift]

Expected Behavior

running build_PyDP.sh should have build PyDP without problems.

Current Behavior

it does not compile, likely as a result of the following error:

src/bindings/PyDP/base/logging.cpp:35:64: error: 'get_log_directory' is not a member of 'Logging_helper'
   35 |   obje.def_property_readonly("log_directory", &Logging_helper::get_log_directory);
      |                                                                ^~~~~~~~~~~~~~~~~
Target //src/python:bindings_test failed to build
INFO: Elapsed time: 3.712s, Critical Path: 3.51s
INFO: 0 processes.
FAILED: Build did NOT complete successfully

Steps to Reproduce Behavior

I tried to build it by forking and cloning the repo, and following the contributor guide.

Steps to remove this behavior

By commenting out /src/bindings/PyDP/base/logging.cpp the build runs without errors

Logs

Are there any logs?

Hey @systemshift
Nice to see people testing the repo !!
Did you run ./ext_source_setup.sh and ./prereqs.sh before running build_PyDP.sh ?

[chinmayshah99]

Hi @systemshift
Thanks for reporting this, I suspect the latest commits in Google DP library cause this break.

@jeamick yeah, @systemshift did run these other dependencies. As a matter of fact, if he comments out logging.cpp, it builds successfully.

We need to investigate this further.

Hey @systemshift
Thanks for reporting this! I have reproduced the problem on Ubuntu 20.04. Before we fix the building process on Ubuntu 20.04 you can build and use the Docker image.

There is actually an error shown a little earlier in the messages:

src/bindings/PyDP/base/logging.cpp: At global scope:
src/bindings/PyDP/base/logging.cpp:23:17: error: 'string' in namespace 'std::__cxx11' does not name a type
   23 |   std::__cxx11::string get_log_directory() {

So far I discovered that removing "__cxx11" from this method definition:

  std::__cxx11::string get_log_directory() {
    return dpb::get_log_directory();
  }

like this:

  std::string get_log_directory() {
    return dpb::get_log_directory();
  }

fixes the building process for me, but I don't currently know if it's a good fix or only a hack.
