I have just recompiled libAfterImage with these flags, and
installed it again, but I have the same errors.
root [0] gSystem->Load("libASImage.so")
(int)0
root [1] TImage *img = TImage::Open("rose512.jpg");
/users/snovae/leguil/usr/lib/root/bin/root.exe: error while loading shared
libraries: /users/snovae/leguil/usr/lib/libAfterImage.so.0: undefined
symbol: jpeg_std_error
I tried also to load /usr/lib/libjpeg.so by myself :
CINT/ROOT C/C++ Interpreter version 5.15.56, Sep 4 2002
Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
root [0] gSystem->Load("libjpeg.so")
(int)0
root [1] gSystem->Load("libjpeg.so")
Note: File "/usr/lib/libjpeg.so" already loaded
(int)1
root [2] gSystem->Load("libASImage.so")
(int)0
root [3] TImage *img = TImage::Open("rose512.jpg");
root [4] img->SetConstRatio(0);
root [5] img->SetImageQuality(TAttImage::kImgBest);
root [6] img->Draw("N");
*** Break *** segmentation violation
Should I recompile root itself to enable the support of
libAfterimage ?
(I am using root 3.03.09, on a Red Hat 7.1 box, with gcc 2.96,
and I installed the binary version from
root_v3.03.09.Linux.RH7.2.gcc296.tar.gz)
Cordialement,
Laurent
