I am testing ROOT-cygwin as an alternative development/analysis environment to my separate Linux partition. I installed the latest version of cygwin and KDE-3, then downloaded the binary for v4.02/00 compiled with gcc v3.3 (the cygwin version is 3.3.3, I hope that’s sufficiently close…)
ROOT works fine, however I can’t compile or link any libraries/executables.
The errors seem to be of two kinds, see the attached examples for test/Aclock and test/Event:
either :
variable ‘vtable for TTimer’ can’t be auto-imported. Please read the documentation for ld’s --enable-auto-import for details.
(case of Aclock, building a shared library)
or :
undefined reference to `TObject::TObjectnot-in-charge’
(case of Event, building an executable).
In both cases I used the Makefile in $ROOTSYS/test.
I have $ROOTSYS/lib in my $LD_LIBRARY_PATH.
Do I have to build ROOT from scratch in order to be able to compile/link with it ?
Thanks for any help

I tried to build ROOT from scratch, following Axel Nauman’s instructions and it all went pear-shaped when trying to build libHist.dll - same errors as before about vtable not being auto-importable (see attached output from ‘make’ command).
Any help would be greatly appreciated as I cannot find the same error anywhere on the forum.
Hi John,
A couple of random comments/questions that may/may not help:
In the test directory, it didn’t work if I typed ‘make Event’, but if I typed ‘make’ so everything it needed compiled, it worked o.k.
What version of Cygwin are you using? In my case
cplager@PointyIII> uname -a
CYGWIN_NT-5.1 PointyIII 1.5.12(0.116/4/2) 2004-11-10 08:34 i686 unknown unknown Cygwin
cplager@PointyIII> gcc --version
gcc (GCC) 3.3.3 (cygwin special)
On my other compuer, I was able to build Root following Axel’s instructions using gcc3.2 and cygwin 1.5.12 (after some rebasing). I’m now using his ’ Version 4.02/00 17 December 2004 ’ out of the box with no problems (so there’s hope )
Hi John,
I cannot reproduce this, with current cygwin and root 4.02/00. I hope you did not install the kde binutils patch…
Ontop of Charles’ questions I need the files from the link line, i.e.
hist/src/Haxis.o hist/src/TAxis.o hist/src/TConfidenceLevel.o hist/src/TF1.o hist/src/TF12.o hist/src/TF2.o hist/src/TF3.o hist/src/TFormula.o hist/src/TFractionFitter.o hist/src/TGraph2D.o hist/src/TGraph2DErrors.o hist/src/TGraphDelaunay.o hist/src/TH1.o hist/src/TH1K.o hist/src/TH2.o hist/src/TH3.o hist/src/THLimitsFinder.o hist/src/THStack.o hist/src/TLimit.o hist/src/TLimitDataSource.o hist/src/TMultiDimFit.o hist/src/TPolyMarker.o hist/src/TPrincipal.o hist/src/TProfile.o hist/src/TProfile2D.o hist/src/TSpectrum.o hist/src/TUtilHist.o hist/src/TVirtualHistPainter.o hist/src/G__Hist.o bin/libMatrix.dll lib/libMatrix.dll.a bin/libCore.dll lib/libCore.dll.a bin/libCint.dll lib/libCint.dll.a? It’d be best if you could tar.bz2 them and put them on the web so I can download them.
Please also send the output of “ld --version”.
I suspect that this is a problem with your .bashrc / .bash_profile / /etc/bash.bashrc. For a complete analysis of your problem I’ll need the output of “env”.
Thanks for the replies.
I had installed the binutils patch for KDE-3 - didn’t know it was wrong!
I uninstalled it and reinstalled the normal cygwin Devel version, and now it seems to work fine - at least, when I go into $ROOTSYS/test and type ‘make’ everything compiles and I was able to load the Tetris.dll and play a game…
Axel, perhaps you should put a warning about binutils in your ‘Hint’ about installing KDE-3 ?
