Compiling Issues

[Digioso]

Heya,

thanks for this tool!
I'm trying to compile this on Windows 10 PC within a Cygwin installation.
I downloaded the rlog 1.4 source code from here and copied it to /usr/include
Looks fine as far as I can see. However your code seems to be having lots of issues unfortunately and cannot be compiled. Could you perhaps have a look at this?

I don't think that it has to do with my, let's say unusual setup. I'm using E3DC-Control for example, which I can compile without any issues.

Hi,
sorry for that.
Most of the code is coming from E3DC's demo. I modified it only to generate some output and I ignored all warnings that were coming from it. Actually I am very unsure if I really should dig more into that "Demo" code and fix all warnings it contains.

There are plenty of issues compiling Linux code on a cygwin environment on Windows. Mainly because of issues with file, event and timing.

Fortunately the Demo Code contains hooks for Windows.
Did you try to define "WINNT"?
can you please run g++ with -DWINNT
and report again?

Thanks

Ralf

[Digioso]

Heya,

thanks for the quick answer. :)
With -DWINNT I'm down to only one error as it seems.

Hi,

actually there should be an include file that defines them like this:
#ifndef STDIN_FILENO
#define STDIN_FILENO 0
#endif

#ifndef STDOUT_FILENO
#define STDOUT_FILENO 1
#endif

#ifndef STDERR_FILENO
#define STDERR_FILENO 2
#endif

Don`t know in cygwin were this is handled.
So you can either search in all include files from cygwin for those defines and add the according include to the source code, surrounded with the WINNT IF's, or you simply define it on the command line like:
-DSTDERR_FILENO=2
This is not a great solution, but it should do the trick.

Please try
Ralf

[Digioso]

Thanks a lot. :)
One step further at least. :)

/usr/lib/gcc/x86_64-pc-cygwin/9.3.0/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lrlog
collect2: error: ld returned 1 exit status

If I see it correctly it now has trouble with rlog.
Do you need a compiled version or the source code? Maybe I have the wrong rlog version?
As I said, I used the 1.4 version from here.

But basically g++ seems to be finding rlog. Before I copied it to /usr/include g++ was complaing about not finding the rlog source code for compilation.

I also added /usr/include (or rather /cygdrive/c/cygwin/usr/include) to $PATH and $LD_LIBRARY_PATH and exprorted both variables prior to compilation.

Hi,
it says it can't find the library rlog. LD_LIBRARY_PATH is a runtime environment variable and not for compiling
please add -L to your compile command. But than you would need LD_LIBRARY_PATH being set for executing the command
It is much better to "compile" the library path into the executable itself.
Like described here: https://stackoverflow.com/questions/2726993/how-to-specify-preference-of-library-path

so please add to you compile line:
-Wl,-rpath,
you can add several paths with that.
Please try.
Ralf

[Digioso]

Thanks for your time. :)

And sorry for all the questions.

I also have a Mini-PC running Linux Mint. Unfortunately rlog doesn't seem to be available in the Linux Mint repository. :(

And it also is not simply possible to replace all rError and rWarning by printf. The syntax of identical but you are using rlog on A LOT more (EG: rDebug, rInfo). So simply removing it doesn't work without mostly rewriting everything. :(

No change with the added parameters. I hope I understodd how they work correctly.

I don't understand what exactly it is looking for, though. From my understanding it is looking for a file or directly named "-lrlog" which obviously doesn't exist.
/usr/include is a default path used by gcc. It is not complaining about not finding rlog.h

Hi,
sorry, but your path is not correct.
You added the path to the "include" files as library path. Include files are header files for compiling. They are not good for linking. The error message is not coming from the compiler but from the linker - bin/ld. The linker is the program that assembles all libraries and compiled files to an executable program.
What you need to add is the path to the library file of rlog. The library file of rlog should look something like "rlog.so" or "rlog.a".
Please change the "-Wl,-rpath,/usr/include" to something like "-Wl,-rpath,/usr/local/lib" and make sure that rlog.so or rlog.a is located in that directory.

OK, now you lost me. :)

Why do you need a compiled rlog? In your tool you're using the rlog header files.
#include <rlog/rlog.h>
#include <rlog/StdioNode.h>
#include <rlog/RLogChannel.h>

What are those needed for when you need a pre-compiled rlog anyway? oO
It's been quite a while that I've programmed in C, but from my past knowledge the header files you include will be used for compiling the binary file. Usually they include additional functions that can be used. Like printf from stdio.h
So all those functions provided by rlog should be taken rlog.h and compiled into the binary file.

Anyway I compiled rlog now and copied the bunch of files from the .libs directory it created to /usr/local/lib
Unfortunately the error message stays the same. :(

OK,
back to the basics of compiling.
Source code -extension .c or .c++ or .cc- is human readable.
Your program may use functions from other programs called libraries. E.g. sprintf is a function from stdio that prints something on the terminal.
For the compiler to know how sprintf looks like you include the definition file stdio.h in your program or the compiler complains that it does not know sprintf. This only means you are including the definition, not the function itself!!
If the compiler is happy with your source code it will generate an object file ".o" that contains only your code and pointers to other needed functions, like sprintf. Object code is not executable!!

Next step is to invoke the linker to collect all needed object files and create an executable file from it. And now we have to distinguish between static libraries ".a" and dynamic libraries ".so". If you hand over a static library ".a" to the linker together with your object code it will embed that static library in the executable. So that executable will contain your code and the library as one program.
If you allow dynamic binding with ".so" libraries- which is the default, the linker will create an executable that does NOT contain the library but only your code and hints to the dynamic libraries. When you start the executable the so called loader will look around for the needed dynamic libraries and will construct a runnable process from it. (Only the loader works with LD_LIBRARY_PATH)
The advantages of dynamic libraries are they consume less memory, because they can be shared between programs and that you can update those libraries without recompiling your own program. Simply stop and restart your program and it will automatically use the fixed library.

So your problem is that you will have to generate a dynamic library of rlog. This normally is done when you compile the sources of rlog and do a "make install". That will compile several .o files and combine them in a rlog.so file or/and a rlog.a file and install that file in the location that was given to autoconf. You have to locate the rlog.so file and set the -Wl.rpath, or the linker will not find it and cannot assemble your object code to an executable.
DO NOT use the files in .libs, they are only there to assemble the so file and will be deleted when you do a "make clean".
The rpath directive is a linker directive and says that the location of rlog.so is compiled in the executable program. But only the location, not the code. If you remove rlog.so your program will not be able to start.

Thanks for the explanation. :)

I indeed did forget the "make install" for rlog. :(

Make install created a librlog.a file in /usr/local/lib .
Unfortunately the compilation still fails with the exact same error message.

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-LLIBDIR' linker flag

Is the librlog.a a dynamic or static library?
please try
file /usr/local/lib/librlog.a
to me that looks like a static library and that is not good for your gcc options.
If it is a static library it might be the best to use it, though the binary will get bigger but you can skip all that rpath or LD_LIBRARY_PATH thing.
please try:
/usr/bin/g++ -lrlog -O2 -DWINNT -DSTDERR_FILENO=2 -Wall S10history.cpp RscpReader.cpp RscpProtocol.cpp AES.cpp SocketConnection.cpp /usr/local/lib/librlog.a -o S10history

If this does not work try it without -lrlog switch

Perfect.

I just compiled it under the Linux App on Windows 10.
I installed the Linux app from Microsoft store, and installed Ubuntu 18 in it.
After opening the Ubuntu app I did:
sudo apt-get update
sudo apt install gcc
sudo apt install g++
sudo apt install librlog5v5
sudo apt install librlog-dev

Makefile has to be changed to:
CXX=/usr/bin/g++
ROOT_VALUE=S10history
LDFLAGS=-Wl,-rpath,/usr/lib/x86_64-linux-gnu -lrlog -L/usr/lib/x86_64-linux-gnu
CCFLAGS=-Irlog -O2 -DSTDERR_FILENO=2

all: $(ROOT_VALUE)

$(ROOT_VALUE): clean
$(CXX) $(CCFLAGS) S10history.cpp RscpReader.cpp RscpProtocol.cpp AES.cpp SocketConnection.cpp $(LDFLAGS) -o $@

clean:
-rm $(ROOT_VALUE) $(VECTOR)

Sorry for cheating, I removed the -Wall to concentrate on errors

Ralf

[Digioso]

OK, the Linux APP would've been indeed an alternative to Cygwin. :)
It's just that I've been using Cygwin for more than 10 years now, so when I want to have Linux stuff on Windows Cygwin is the first thing that comes to my mind.

[Digioso]

I rewrote your getYearperDay.sh example into a Perl program and added installation date as a required parameter (so that you cannot request dates prior to installation of the E3DC system).
If you request data from the installation year the script also sets the starting day to the installation date (in my case 31.10.2019).
Required paramaters for your tool (user, pw, ...) are now read from a config file.
And I reduced the output to the three values that I am interested in the most (kWh production, kWh into the grid and kWh used by the house).
Maybe this is useful to someone else as well. :)
I'm going to write another script to run daily, save the values and create a monthly report.

Sample output:

Digioso@DigiSlave ~/S10history
$ ./daily.pl 2018
The given year is lower than the installation year. That doesn't work.
Usage of this program:

./daily.pl YYYY
Example: ./daily.pl 2020

Year cannot be lower than the installation year.
Digioso@DigiSlave ~/S10history
$
Digioso@DigiSlave ~/S10history
$ ./daily.pl 2019
Setting startdate to installation date 20191031.
31.10.2019 Production: 4.13 kWh Into Grid: 1.37 kWh Usage: 2.76 kWh

The script has to be put into the same directoy as S10history binary.
config-file named config.ini also needs to be placed there.

Example config.ini file:
USER = your_e3dc@mail.address
PW = e3dc_website_password
AES = aes_password
IP = 1.1.1.1
INSTALLDATE = 20191031

And the script:

# Function  : Prints information about solar production, how much went into the grid and consumption
#
