I did. / configure to make a makefile
but it ran into an error: configure: error: Could not find a usable sed version:
Then I typed who sees
shows / usr / bin / sed.
So what happened? why fails. / configure find sed?
I had this problem on my mac. This is because OS X is using an older sed version. Installing gnu-sed with brew install gnu-sed and alias gsed=sed solved the problem. You can install gnu-sed in a different way.
brew install gnu-sed
alias gsed=sed
