Hello,

thanks.
Hi @Mansi ,DDASEvent::DDasEvent() defined (in what library or .o file), and is AnalyzeDDAS linked against that file?
Cheers,
Mansi

helloDDASdict.cpp (19.3 KB)
Yes, AnalyseDDAS is linked to that file.
Mansi
It doesn’t seem to be? In your original output I don’t see a DDasdict.cpp being passed anywhere.
Anyway when the linker complains that some symbols are undefined like that, typically the solution is to pass the object file (or the source file) that defines them to the compilation command (after the object that needs them, when it comes to linking order matters).
Cheers,

I have used the same program before, and it worked with out any errors.
I can’t say why or how it worked before, sorry.
When you compile a library or an executable, you have to pass all libraries (or sources) that provide the symbols that the library or executable being compiled requires. Here the linker is complaining that it sees that DDASdict.cppAnalyzeDDAS.cpp needs the symbol DDASEvent::DDASEvent() (and others) but it’s not present in any of the libraries that are being passed to the compilation command.
If you know that DDASEvent::DDASEvent() is defined in DDASdict.cpp, it should be sufficient to pass that file to the compilation command for AnalyzeDDAS.cpp to fix the linker error.

Those warning are likely relevant. They indicates that either the class are misspelled or that the rootcint/rootcling invocation is missing headers (Currently it sees ‘only’ Parameters-ddas.h and whatever that includes).

I could resolve the problem and can “make” now.

Hi,
The current problem is a segmentation fault in betadecay::~betadecay(). That is typically a bug in memory/lifetime management in the user’s code. You can try compiling the application without optimizations (no -O compilation flags) and with debug symbols (-g compilation flag) to get better stacktraces: that will tell you exactly at what line the invalid memory access is happening.gdb to inspect the state of the program at the time it crashes.
Also please check out Posting code? Read this first! for instructions on how to post code. I edited your previous post to make it more readable.
Cheers,
