dear rooters
while the gnu compiler version of root seems to work fine under irix 6.3
and linux. i get the following result
with the version that used the kai compiler (which is the forced
standard in the CDF experiment)
when i use the shared memory tutorial.
root [0] .x hprod.C
Error in <TMapFile::TMapFile>: no memory mapped file capability
available
Error in <TMapFile::TMapFile>: mapped file not in mmalloc format or
already open in RW mode by another process
Memory mapped file: hsimple.map
Title: Demo memory mapped file with histograms
Option: file closed
Mapped Memory region: 0x0 - 0x186a0 (0.10 MB)
then i have another unrelated question. After the creation of the memory
mapped file in the tutorial hprod.C i would like to monitor the
contents of the file but if i add TBrowser like in the example below i
get the an empty TBrowser window which only becomes active when i
interrupt the macro.
Is there a way to open an active browser?
same for the canvas in hcons.C how can i make it active
thanks a lot
