Re: [ROOT] Fixing automatic streamers

Re: [ROOT] WARNING: Plan to drop support for several platforms

Just a small addition concerning HP-UX and aCC. The problem is that at CERN we have only access to the very old and non standard C++ compliant HP-UX 10.20 version of aCC. Modern versions of aCC on HP-UX >=11 will probably work without too many problems but as long as we don't have access to such a platform we can not guarantee the portability of ROOT to HP-UX >= 11. Anybody with such a platform who wants ROOT should lets us know and provide us with access. Cheers, Fons.

[ROOT] Interacting with Geophysical timeseries data in SEGY format?

Hello Can I use ROOT framework to interact with Geophysical timeseries data in SEGY format? Any suggestions/comments?

[ROOT] WARNING: Plan to drop support for several platforms

Dear Rooters, In order to improve our support for new platforms, we are planning to drop support for old OS/compilers. From our FTP distribution site, we still see several imports from the following versions, but it looks like people importing these files are just mirroring our site. The binary versions that we are planning to drop are: -AIX.5.tar.gz -HP-UX.B.10.20.aCC.tar.gz -IRIX.6.5.cc.tar.gz -IRIX.6.5.gcc.tar.gz -IRIX.6.5.kcc.tar.gz -Linux.RH6.1.gcc2952.tar.gz -OSF1.V4.0.cxx6.tar.gz -OSF1.V4.0.tar.gz -SunOS.5.7.tar.gz In addition, we would like to drop support at the source level for the HP-UX/aCC compiler, the egcs compilers and MS/VC++6. Please, let us know as soon as possible, if you are still using these binary files or compiling from source for aCC, egcs compilers or MS/VC++6. In case you are still using these old systems/compilers, could you tell us when you are planning to move away from these systems. Note also that under Windows, we will drop support for the win32 version, supporting only win32gdk and win32gcc. Rene Brun
