When compiling openconnect on Mac OS X , i got these error. Its strange, since autoheader is just perl script. ( Windows )
Google with many keywords don’t direct to conclusion. After 3 hours of mimicking my friend laptop, i got this: Don’t use FAT32, use Mac file system. I installed OSX and Ubuntu on this machine. Since Mac default system doesn’t recognized ext4 file system, we need to create FAT32 as shared file system to save space.
So, open to many possibilities when dealing with unintuitive error messages.
When you log on to linux console, usually you see something like
web@w22 log $
comp-web : user who log in; w22 : host name ; log : current folder.
But you dont know full folder path, to show that use this command
$ export PS1="\[33[01;32m\]\u@\h \[33[01;34m\]\w \$ \[33[00m\]"
