Calling root from a shell script

ROOT

Hi All,

I have do create a bunch of plots and each set is made from a separate directory. I wrote a script to edit the macro which creates the plots and I edited the macro to save the correct plots so I can run this in batch mode.

when I run from the command line I use:

root -q -b …/…/llrPlots.r+

and get

then runs like a charm.

but when i call from the shell script using root.exe -b -q …/…/llrPlots.r+
I get

I am sorry if this is not enough information. I am new to the shell scripting and have the learn the tricks but I have called other programs from a shell script, but never compiled one.

Hi,

something in your batch file’s environment is terribly wrong. Compare the output of “env” run in the batch script (where ACLiC doesn’t work for you) and on the prompt (where ACLiC does work); PATH is probably pointing to something invalid. You can also compare the output of “which gcc” in the two cases. Can you also make sure that you get consistent results with root -q -b …/…/llrPlots.r+ and root -q -b …/…//llrPlots.r+ (one vs. two slashes)?

Cheers, Axel.

Thanks for the ideas.

I tried the simplest first, and of course it was the problem.

root -b -q …/…//llrPlots.r does not work
but
root -b -q …/…/llrPlots.r does work

The path to the macro name is entered by the user so as insurance I usually add a slash when I piece together the full path incase. This is the first time it has ever given me a problem.

Thanks

Hi,

…and I would call it a bug. But I cannot reproduce it, so I suppose it has been fixed already. I tried cd $ROOTSYS/tutorials/fit/.svn root -b -q ../..//hsimple.C+ root [0] Processing ../..//hsimple.C++... Info in <TUnixSystem::ACLiC>: creating shared library /build/axel/root/deb/tutorials/fit/.svn/./../../hsimple_C.so hsimple : Real Time = 0.17 seconds Cpu Time = 0.18 seconds (class TFile*)0x16d4a00
So it works for me.

Cheers, Axel.
