I installed libAfterImage, and compiled root from
root_v3.03.09.source.tar.gz ; but the compilation
of TASImage module failed :
g++ -O -pipe -Wall -Woverloaded-virtual -fPIC -Iinclude
-D_REENTRANT -I/users/snovae/leguil/usr/include/libAfterImage/ -o
asimage/src/TASImage.o -c asimage/src/TASImage.cxx
asimage/src/TASImage.cxx: In function `Bool_t TASImage::InitVisual ()':
asimage/src/TASImage.cxx:1276: cannot convert `Colormap' to `ASVisual
*' for argument `5' to `create_asvisual_for_id (Display *, int, int,
long unsigned int, ASVisual *)'
gmake: *** [asimage/src/TASImage.o] Erreur 1
What is wrong ?
Cordialement,
Laurent
