Compiling HAProxy on OS X
If you want to use PCRE when building HAProxy on your mac (recommended by the docs) and you've installed PCRE using MacPorts (
sudo port install pcre), you may need to tweak Makefile.osx to help it find the headers, otherwise you'll see a whole slew of errors starting with this:
In file included from include/types/proxy.h:34,
from include/common/cfgparse.h:29In file included from include/types/proxy.h:34,
from include/common/cfgparse.h:29,
from src/haproxy.c:63:
include/common/regex.h:28:18:,
from src/haproxy.c:63:
include/common/regex.h:28:18: error: error: pcre.h: No such file or directory
include/common/regex.h:29:23: error: pcreposix.h: No such file or directory
To fix that, open up Makefile.osx and find the two lines that define PCREDIR:
PCREDIR!= pcre-config --prefix 2>/dev/null || :
#PCREDIR=/usr/local
I commented out the first line, uncommented the second line and modified it to point at /opt/local instead of /usr/local:
PCREDIR=/opt/local
After that the compile worked. While I was at it I also set ARCH=x86_64 and TARGET=darwin, though I'm not sure if it actually accomplished anything.
