From 2016, OCPWin is managed by a tool
ocpwin.exe. The tool was mostly introduced to
avoid the PATH corrupting bug in NSIS installer.
Thanks to this tool, it is now possible to install multiple
versions of OCPWin at the same time on a computer, and to
ocpwin.exe to switch between them.
$ ocpwin.exe -list 4.01.0+ocp1-msvc64-20160113 4.01.0+ocp1-msvc32-20160113 4.01.0+ocp1-full-mingw64-20160113 $ ocpwin.exe -switch 4.01.0+ocp1-full-mingw64-20160113
ocpwin.exe cannot change the PATH in
the current shell, so after using
ocpwin -switch, you
should start a new terminal to enjoy the new settings.
However, it is possible to use wrappers to avoid this problem. If you use:
ocpwin.exe -multi-switch true
ocpwin.exe will create a directory containing wrappers
for all the OCaml commands, and add it in top of the PATH. These
wrappers will always select the current switch OCaml commands, so you
that any call to
ocpwin.exe -switch will be immediatly
seen in the current terminal.
It is possible to remove these wrappers by calling:
ocpwin.exe -multi-switch false
