When trying to build the Unix QuickFIX engine, I get the following error after ./bootstrap
warning:macro 'AM_PATH_XML2' not found in library
As I understand, libxml2 already comes with XCode OS X Mountain Lion. An answer I found suggested to download libxml2-dev, although I could not find the package using HomeBrew.
I'm relatively new to programming on OS X and Xcode and porting Unix applications, so I'm not sure exactly what I have yet.
I did a
brew install libxml2
Then poking around I found the macro AM_PATH_XML2 in /usr/local/Cellar/libxml2/2.8.0/share/aclocal/libxml.m4. Which is all the dev package contents, then I compared to my Ubuntu/Vagrant virtual I have locally that was working fine and remembered to:
brew link --force libxml2
which put the symlink in /usr/local/share/aclocal.
And now I'm building, but I also needed automaker, so to recap
brew install automake autoconf libtool libxml2
brew link libxml2
That warning comes from Autoconf and is complaining that the configure.in file refers to the macro AM_PATH_XML2 but it isn't defined. It should be defined in the file aclocal.m4 in the quickfix source, so it seems your version of autoconf isn't finding it.
You could try modifying bootstrap to run autoconf -I .
I just ran into this problem trying to build oath-toolkit on my mac. I was able to get past this error by creating a symlink for libxml.m4 after installing with brew install libxml2.
ln -s /usr/local/opt/libxml2/share/aclocal/libxml.m4 /usr/local/share/aclocal/libxml.m4
I realize this question was asked more than 7 years old, but it took me a while to piece together this solution. I hope it helps. I was able to reproduce the problem my running aclocal. It errored with configure.ac:38: warning: macro 'AM_PATH_XML2' not found in library. I then ran aclocal --print-ac-dir which returned /usr/local/Cellar/automake/1.16.1_1/share/aclocal. That directory contained a dirlist file.
cat /usr/local/Cellar/automake/1.16.1_1/share/aclocal/dirlist
/usr/local/share/aclocal
/usr/share/aclocal
The first directory contained all of the other symlinks.
ls -al /usr/local/share/aclocal

Following that pattern, I could have done:
ln -s /usr/local/Cellar/libxml2/2.9.9_2/share/aclocal/libxml.m4 /usr/local/share/aclocal/libxml.m4
But I chose to use this symlink so that this answer works with various versions.
ls -al /usr/local/opt/libxml2
lrwxr-xr-x 1 cameron admin 25 Sep 20 09:35 /usr/local/opt/libxml2 -> ../Cellar/libxml2/2.9.9_2
