Hi Gilbert,
No need to rename the directory as the Cygwin 64 bit will be installed
in C:\Cygwin64 folder
Attached the script that I use to reinstall my system on different computers.
It can be adapted to duplicate the 32bit in a 64 bit installation
Assuming your file list is not longer than 32K, this should work :
chmod + x cyg-reinstall.sh
sed -e "1d" /etc/setup/installed.db | sed -e "s/ .*$//" > filelist.txt
./cyg-reinstall.sh -f filelist.txt
cp cyg-reinstall-x86.bat cyg-reinstall-x86_64.bat
sed -i -e "s/setup-x86.exe/setup-x86_64.exe/" cyg-reinstall-x86_64.bat
if the "filelist.txt" is too long you can split in multiple chunks, like:
grep -v "^lib" filelist.txt > nolib-list.txt
grep "^lib" filelist.txt > lib-list.txt
I usually need to split mine, as my installation hit the 32K limit of
command line
wc -l *.txt
2608 filelist.txt
1297 lib-list.txt
1311 nolib-list.txt
ls -1s *.txt
40K filelist.txt
20K lib-list.txt
20K nolib-list.txt
Regards
Marco
