Loading on start up

ROOT

_ROOT Version:6.28
_Platform:Windows 11
_Compiler:Cling, Visual c++, gnu g++

I’m trying to load my libraries at root start up with ‘root -l name.cpp+’ as sugested somewhere here for Linux. It does recognize ‘-L’ – maybe its a Windows thing.

I don’t really care how it’s done – all I want to do is not enter ‘.L name.cpp+’ many times. A scripte would do it but that doesn’t seem to work for ‘…’ commands

Try

root -e '.L name.cpp+' -e '.L other.cpp+' ....

Thanks. I’ll try that. I tried something like ‘root -L name.cpp+’ whice some body suggest. It doesn’t work on Windows may on Linux. ‘-e’ makes sense!

I found I could only load one ‘.cpp’ file that way, but I have come up with a solution.
I make a file I call ‘load.cpp’ and it is series of includes like so
#include “rFlat.cpp”
#include “boostTo.cpp”
#include “ProbDStarLNu.cpp”
#include “PickAngles.cpp”

‘.L load.cpp++’ creates a single library file (‘.ddl’) with all my stuff in it and available from the command line.

That should not be the case. What is the exact command line that you tried?

It was based on this:

alias roott=’root -l -L /path/to/lib/library.so -L ~/path/to/file.cpp+

I removed the library as I don’'t have one on windows and changed the pat to the cpp file (which was local to the directory I run root in).

It does not even recognize ‘-L’

PS C:\Users\snyde\BFROOT> cd .\ROOT\
PS C:\Users\snyde\BFROOT\ROOT> C:\root_v6.28.06\bin\root.exe -L .\bDecay.cpp+
root: unrecognized option '-L'

However with -e that works.

Ah! Trying more variations, I find the repeating the ‘-e’ command for each ‘.L’ works

C:\root_v6.28.06\bin\root.exe -e ".L .\load.cpp++" -e ".L .\bDecay.cpp++"

==>load.cpp is my files with the ‘includes’ which puts all the functions specified in a single library…and ‘bDecay.cpp’ is what I’m working on that depends on them.

It should not :slight_smile:

Exactly :slight_smile:

-L is not a command line argument of root.exe
-e is a command line argument of root.exe which says to please execute the next parameter as if it was written on the ROOT command line.

Yes. I finally figured that out for myself after trying many other possibilities.

Thanks!!!
