This might very well be a Homebrew issue, but I'm posting here in the hope that someone else might have found a solution. I have trouble building zsh with included pcre support on recent versions of Homebrew. I have previously always installed brew zsh with the pcre option, but the Homebrew project this Fall decided to remove all configuration options from their core packages, and it's thus no longer possible to install zsh with the pcre option on without editing the formula. However, although I have tried editing the formula, something doesn't work in the install process. I have done a "brew edit zsh", and then added the line ' "--enable-pcre", ' to the configure options. Then I ran "brew install --build-from-source --verbose zsh". I can see from the output that configure is run with "--enable-pcre", but later in the log I see this: checking for pcre_compile... no checking for pcre_study... no checking for pcre_exec... no So I assume something is preventing the build from finding the pcre libraries, although the configure script has been run with such support. I have both pcre and pcre2 installed: pcre 8.42 pcre2 10.32 Does anyone know how to resolve this?
