checking for APR... no
configure: error: APR not found.  Please read the documentation.



{   When it tells you Please read documentation it means that you should go read Apache documentation ( http://httpd.apache.org/docs/2.4/install.html ) which tells you to
download the latest versions of both APR and APR-Util from Apache APR, unpack them into ./srclib/apr and ./srclib/apr-util (be sure the domain names do not have version numbers; for example, the APR distribution must be under ./srclib/apr/)

then do

./configure --with-included-apr   }


now download and install apr and apr-utils

apr:

./configure --prefix=/usr/local/apr

Could not compile libxml2: /bin/rm: cannot remove `libtoolT’: No such file or directory

solution:

When I compile libxml2-2.7.8 under Ubuntu 11.04, it always complain that:
/bin/rm: cannot remove `libtoolT’: No such file or directory.
I did a search on google, but none of them works.
From the console output, I found that it failed because removing a file which does not exists.
So I edit the configure file, find the line which contains $RM “$cfgfile”, and replace it with $RM -f “$cfgfile”, then everything works.
(‘rm -f’ means do not stop even if the file doesn’t exists)

make
make test
make install
cd test/
./testall
