Hi PgSQL Hackers,

I am overseeing a few hundred/thousand  postgres/pgagent installations and on one installation the pgAgent does not start with a message as a service on a Windows Server:
ERROR: Couldn't register event handle.
once the service is being started. Investigation showed that this is not an issue of logging in as postgres, neither is this a connection issue to the postgres DB, see more details at





It seems to me that pgAgent tries and fails to write something to the windows logger . To confirm/reject this hypothesis I decided to download the sources of pgAgent adjust the code a bit, and see it for myself. This is what I did:

(1) I installed MS Visual Studio 2017 Community (MSVS)
(2) I downloaded wxWidgets, compiled it with the MSVS in UTF, Debugging and Release, win32 Settings (to F:\pgbuild\wxWidgets-3.1.1)
(3) I downloaded, extracted, cmake-gui'ed pgAgent-3.4.0-Source into F:\pgbuild\pgAgent-3.4.0-Source
(4) I download the 9.6 32bit postgres and extracted it into F:\pgbuild\pgsql
(5) I adjusted pgAgent MSVS solution configuration to include F:\pgbuild\wxWidgets-3.1.1\lib\vc_lib\mswud and F:\pgbuild\pgsql\lib
(6) F:\pgbuild  has also libiconv, libxml2, libxslt
(7) I am able to compile pgAgent to the point that the executable is created (that dies if I run it), other targets (ALL_BUILD, INSTALL, etc.) cannot be built successfully with the following error:


1>------ Build started: Project: run, Configuration: Debug Win32 ------
1>Generating pgagent--3.4.sql, pgagent.control
1>CUSTOMBUILD : CMake error : Error processing file: cmake/MakeExt.cmake
1>Done building project "run.vcxproj" -- FAILED.
2>------ Skipped Build: Project: INSTALL, Configuration: Debug Win32 ------
2>Project not selected to build for this solution configuration
3>------ Skipped Build: Project: PACKAGE, Configuration: Debug Win32 ------
3>Project not selected to build for this solution configuration
========== Build: 0 succeeded, 1 failed, 4 up-to-date, 2 skipped ==========




Questions:

(1) How can I compile and debug PgAgent (i.e., address compilation issues)?
(2) Any comments, how to get pgAgent running?

Cheers,
Arturas
