<TUnixSystem::DynamicPathName> problem

ROOT
1

Hi rooteers!
I patted my head too much, so I decide to ask help.
I downloaded the pre-compiled binaries (v5.22-gcc3.4) for SL4 and ROOT does work very well.The problem is about my own compiled programs. I wrote down many ROOT-based classes to do my own analyses.
Then I compiled them, each with the following command:
g++ root-config --cflags -I FileToCompile1.cpp -c -g
g++ root-config --cflags -I FileToCompile2.cpp -c -g
…
At the end I linked them in the following way:
g++ root-config --cflags --libs -I FileToCompile1.o FileToCompile2.o … main.cpp -o main.exe -g
…
Then execute:
./main.exe
And IT WORKS FINE!
Nevertheless, the following error messages appear at the end:

Error in <TUnixSystem::DynamicPathName>: libMatrix.so does not exist in /home/roberto/ROOT_CERN/root/lib/libCore.so /home/roberto/ROOT_CERN/root/lib/libMinuit.so -L$ROOTSYS/lib -lCore -lCint -lMathCore -lRint Error in <TCint::AutoLoad>: failure loading dependent library libMatrix.so for class TH1 Error in <TUnixSystem::DynamicPathName>: libHist.so does not exist in /home/roberto/ROOT_CERN/root/lib/libCore.so /home/roberto/ROOT_CERN/root/lib/libMinuit.so -L$ROOTSYS/lib -lCore -lCint -lMathCore -lRint Error in <TUnixSystem::DynamicPathName>: libMatrix.so does not exist in /home/roberto/ROOT_CERN/root/lib/libCore.so /home/roberto/ROOT_CERN/root/lib/libMinuit.so -L$ROOTSYS/lib -lCore -lCint -lMathCore -lRint Error in <TCint::AutoLoad>: failure loading library libHist.so for class TH1
When I invoke ldd, this is the answer:

Let me conclude by adding that these messages occurr only when the TH1F::Fit(TF1*…) method is invoked.
Does anyone have any idea what is happening in my comp?
Thanks in advance,

Hi,

A priori this problem has been fixed recently in the SVN trunk.
To work around the problem create a TApplication object in your main routine.

Cheers,
Philippe.

:smiley: Thanks! No longer error messages!:smiley:
I downloaded and compiled the SVN version 5.22.00.
Will this bug be fixed in the version 5.24.00?
Thanks
Roberto
