Answer 1

The latest version of Phalcon uses PCRE libraries.
You can install them like so:
sudo apt-get install libpcre3-dev
and then try and install Phalcon again
For CentOS you will need to use
sudo yum install pcre-devel

For Mac you can use
brew install pcre

For Mac without brew
Go to https://www.pcre.org/ and download latest pcre:,
tar -xzvf pcre-8.42.tar.gz
cd pcre-8.42
./configure --prefix=/usr/local/pcre-8.42
make
make install
ln -s /usr/local/pcre-8.42 /usr/sbin/pcre
ln -s /usr/local/pcre-8.42/include/pcre.h /usr/include/pcre.h

For mac osx maverick you can use
brew install pcre
if it gives you error, you can use
sudo ln -s /opt/local/include/pcre.h /usr/include/
sudo pecl install apc
I have installed pcre via homebrew in Big Sur, so linked as:
sudo ln -s /opt/homebrew/include/pcre2.h /usr/local/include/

To include pcre.h file, search the package archives for the pcre.h file.
To do this I use a command called apt-file (
apt-get install apt-file
and
apt-file update
if you don’t have it installed).
Then search for the pcre package:
apt-file search -x "/pcre.h$"
The -x informs the command that I want to use a regular expression as the pattern. apt-file provided me with three hits:
kannel-dev: /usr/include/kannel/gwlib/pcre.h
libajax6-dev: /usr/include/ajax/pcre.h
libpcre3-dev: /usr/include/pcre.h
The last one is the one I want:
apt-get install libpcre3-dev
This will solve the problem with pcre.h file compilation problem. Hope it will help others, who may come to find an answer to this thread.

For MacOS monterey amd64 (darwin), it is necessary to create a symlink.
First, locate where the pcre.h was installed by Brew:
$ brew list pcre | grep 'pcre\.h$'
/opt/homebrew/Cellar/pcre/8.45/include/pcre.h
Then, gets the directory that GCC is looking for header (.h) files:
$ cpp -v
...
#include <...> search starts here:
/Library/Developer/CommandLineTools/usr/lib/clang/13.0.0/include
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include
/Library/Developer/CommandLineTools/usr/include # <---- we are going to use this one
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks (framework directory)
Finally, create a symlink to the pcre.h file, so that GCC will find it in its search path:
ln -s /opt/homebrew/Cellar/pcre/8.45/include/pcre.h \
/Library/Developer/CommandLineTools/usr/include/pcre.h
To test if it worked, we can use the following C code:
#include <stdio.h>
#include <pcre.h>
int main() {
printf("lala popo");
return 0;
}
And run:
gcc test.c -o test
