Just for clarification: The existing SS12 installer uses a SYSV package with only links in it to optionally place links in /usr/bin for SS12. Solaris 10 packages will normally over-write files that are already on the system.
The one-pager also describes a separate package for the symlinks. The existing unbundled SSX in OpenSolaris today doesn't have a separate package for the links, but it should. If this case is implemented, we'll need to deliver future unbundled Sun Studios to OpenSolaris with a separate package for the links. For OpenSolaris, if the bundled compilers install /usr/bin symlinks, then the unbundled compilers would need to stop installing the unbundled links package by default. One reason the user might want to add /usr/compilers/bin to their search path, is if they are on a shared machine that has a different set of links installed in /usr/bin. You can choose to use the bundled compilers, even if the links are not present. Presumably if they are on their own machine they could just install the links package that they want. But if they need to control the compiler selection differently for different projects, on their own machine, they still might want to have unbundled /usr/bin links and put /usr/compilers/bin on their search path at certain times. --chris Danek Duvall wrote: > On Thu, Jan 15, 2009 at 02:25:44PM -0800, Douglas Walls wrote: > >> So, if you have installed the unbundled Sun Studio, like the upcoming Sun >> Studio 13, with its package that overrides the links in /usr/bin and >> /usr/share/man, and you have some reason you want the bundled compiler >> back on your path. > > Um.
