Hi Markus,
It claims that this is missing ... however it isn't missing ...
The files are all there and are all where they should be. That's what's
puzzling me.

Hello, Chris,
in the module Logger the header file boost\system\error_code.hpp is
missing, in the directory target/dependencies.
I'll take a look at the Maven topic at this point.
Best regards
Markus

Betreff: Re: [C++] Getting the logger module working?
So,
I just checked the changes ... and the build does not work correctly.
But I left the compilation enabled and we will have breaking builds until
this is fixed.
The error message is:

The strange thing is that I triple- and quadruple-checked that the file
(boost\system\error_code.hpp) is there and the directory is correctly
referenced in the CMakeFile.txt:
target_include_directories (plc4cpp-utils-logger PUBLIC
target/dependencies/include)
So something strange must be going on in there ... unfortunately I stopped
C and C++ development in the early 2000s so I'm not 100% sure where to look.

Hi Markus,
I did talk to you about this in our last session. And it once worked
while we did it in Stuttgart.
You introduced the problems by dropping code you didn't test with our
primary build system, which is Maven.
And it's not really a fun trip for me to travel to Stuttgart cause it
takes me about 6 hours of travelling, so I would rather not do this over and
over again.
And it's not quite the Apache way to do these private one-to-one
meetups. I would be happy if we stared discussing C++ related things on this
mailing-list, as we are discussing all the other ones.
Feel free to sign-up to our plc4x slack channel if you prefer that, but
we should only use this for chats, fun and informal discussions. The deeper
discussions should happen here.
Right now the primary build system is Maven and the aggregational CMake
files were a convenience to help use other IDEs (VisualStudio, CLion, ...).
The problem is, that if we don't do this, we will be having big
problems when starting to generate drivers. I would not really like to develop
a plugin for each build system.
In maven it's considered absolute bad practice to reference resources
outside the maven module ... so the referencing stuff "../../../src/main/cpp"
is not a good thing.
That's why I introduced the packaging and the unpacking in the build as
this allows to add a maven dependency to the pom and the managing of the links
to
dependencies is handles as all dependencies are located in the same
directory. So this simplifies the management of the CMakeFile.txt as you only
need one entry
for all dependencies: target/dependencies/include
So if you have a better suggestion how to manage the dependencies and
the driver generation in the future, I'm open for this.
Otherwise I would like to keep things the way I set them up.
I know that with C# and Python we will be having exactly the same
problems ... but at least for C++ I had thought I had solved them.

Hello, Chris,
I looked at the pom.xml on the weekend. To resolve the dependencies
towards Boost, a local duplicate is created in the Dependencies folder. The
duplicate is then created for each module.
To include Boost in CMake you can use the following in the top
level:
set(BOOST_ROOT "./libs/boost/target/boost_1_70_0/")
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
find_package(Boost COMPONENTS filesystem log REQUIRED)
In the sub CMakes Boost can then be used as follows:
TARGET_LINK_LIBRARIES (plc4cpp-utils-logger ${Boost_LIBRARIES})
target_include_directories (plc4cpp-utils-logger PUBLIC
${Boost_INCLUDE_DIRS})
Duplication of the code is then no longer necessary.
@Chris: I think we should solve the topic pom.xml together in one
appointment (Stuttgart?).
The errors in the cpp files I have just made a commit to the branch
"develop".
Best regards
Markus

Betreff: [C++] Getting the logger module working?
Hi all (especially Markus),
I noticed that I had to disable the compilation of the logger
module in the plc4cpp as I am getting errors.
Would be great if you could look into them.
In order to do this, you need to comment in the cmake-compile
execution in: plc4cpp/utils/logger/pom.xml I tried finding out what’s wrong,
but gave up in the end.
Chris
