Is it ok to replace or update Quartus's Cygwin installation?
Precisely 2 Question:
1. Is it Ok to replace delete Quartus's Cygwin installation and put a newly customized cygwin package in same default location? location such as C:\altera\13.1\quartus\bin\cygwin C:\altera\13.1\quartus\bin64\cygwin 2. Is it Ok to use latest cygwin setup exe (from https://cygwin.com/setup-x86.exe) to update & install some other tools on Quartus's Cygwin installation? like targeting the installation locaton by: setup-x86.exe -R "C:\altera\13.1\quartus\bin\cygwin" -l E:\cygwin_pack_forInstall\ -v -P wget,chere,mintty,lynx "Is it OK" means... will it cause error / weird symptoms in Quartus/NiosII/Qsys during build or the built binary-outcome? Don't know has anybody had any study in such methods? :S My scenario is, me & my colleagues all installed Quartus 13.1(windows version) We might use NiosII shell to modify/enhance some workflow, this may need install/update some additional packages on cygwin But i don't want to open another cygwin shell / install another cygwin installation to accomplish such enhancement. :S And precisely one of the problem now is I found the default installed mintty working weird. (need press twice close button to close) But if I update mintty, the problem is gone!
