Error in TDecompBase.h

ROOT

Hi,

I need to do some matrix arithmatic in a C++ program I am writing. When I try and include the SVD class header

I get the following compiler error:

[quote]++ -g -Wall -I/usr/local/root/include -o neutrinoPulse.o
-c neutrinoPulse.cc
In file included from /usr/local/root/include/TDecompSVD.h:22,
from NuPulseHit.hh:15,
from neutrinoPulse.cc:23:
/usr/local/root/include/TDecompBase.h:74: error: syntax error before `-’ token
make: *** [neutrinoPulse.o] Error 1
[/quote]

line 74 of TDecompBase.h reads:

so this doesn’t appear to make sense.

I have the following include statements in the code:

#include <TVector3.h> #include <TMatrixD.h> #include <TMath.h> #include <TRandom3.h> #include <TH1F.h> #include <TF1.h> #include <TFile.h> #include <TGaxis.h> #include <TObjArray.h> #include <TObject.h>

and the following dynamic links in my makefile:

$(C++) $(CFLAGS) -rdynamic -L$(ROOTSYS)/lib -Llib -lCore -lCint \ -lHist -lGraf -lGraf3d -lGpad -lGui -lTable -lTree \ -lPhysics -lMatrix -lRint -lX3d -lm -ldl -lpthread

am I missing a header or dynamic library required for the SVD class?

I run root 4.00/04 on Linux Fedora Core 1 with g++ 3.3.2

Regards

Hi,

This is very strange. The most likely cause is that some header #define one of the word on the line and/or there is a problem before the inclusion of the file.

Either way, you can run

and see what the C++ compiler really tries to compile.

Cheers,
Philippe.

Thanx for the tip, we got around this by removing the variable name in the function declaration, hence line 74 now reads
