Error building : fatal error: pcre.h: No such file or directory
Solution 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

Solution 2
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/
Solution 3
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.
Solution 4
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
