Fix Build #12

Closed Murmele closed 1 year ago

Murmele commented 1 year ago

add expat as requirement

Murmele commented 1 year ago

ok now it did not fix

ihedvall commented 1 year ago

Both the libexpat.a and libmdf.a are installed into the .../lib/* install directory. If it finds the mdf library it should also find the expat library. Maybe find expat before finding mdf should solve the problem?

Sorry about the interrupt on MDF library. I have been working with an delivery regarding CAN logger MDF files. I have made a DBC library with message parsing at least for some of the CAN protocols (NMEA 2000 and raw CAN). It is extended signals (more than 8 bytes) that require knowledge about the protocol in use for the CAN bus.

I don't know the current status regarding your usage of the mdflib. Please let me know.

Hi @ihedvall currently I was not able to finish the work for the mdflib, because of missing c++20 support on our side Currently I am implementing vector blf because there is a library able to use c++11. There I had also to parse a dbc file. I used the following library there: https://github.com/LinuxDevon/dbc_parser_cpp

Are you including the file into the mdflib or as separate?

ihedvall commented 1 year ago

It isn’t impossible to fix the mdflib so it works with C++ 11 compilers. Please let me know if I should do this?

Regarding DBC files, Vector have added an extended multiplex signal definition on top of the normal multiplexed signal. You may find the ParseMessage() function in ihedvall/dbclib/src/network.cpp, message.cpp and signal.cpp files useful.

You can reach me on email @.*** if you have any problem.

Best regards

Ingemar Hedvall

If you have the time to do it would be nice. I will finish the blf import for labplot. Implementing mdf should be then pretty straight forward and quite simple.

@ihedvall From next version of labplot on, we can also support C++17. So you don't have to port down to C++11

Murmele commented 1 year ago

I had a big issue with my parsing of the data regarding little endian and big endian. So in the next weeks I will try to get the dbclib ready for using in labplot

ihedvall commented 1 year ago

The MDF library is now C++ 17 but I haven't tested it in Linux and iOS yet. There will be some/same issues in the DBC library as with the MDF library regarding C++20->17. The library is not dependent on boost. There is some CAN bus protocols missing but it should handle most 8 byte messages.
