problem installing PHP 5 xml2-config not found

Hi, im trying to get apache server with php 5.2.1 up and running on debian sarge
i got apache installed and am trying to get php to configure but it gets to configuring extensions and gets this error:

checking for xml2-config path...
configure: error: xml2-config not found. Please check your libxml2 installation.

i installed libxml from libxml2-2.6.27.tar into /apps/libxml2-2.6.27 and used the following in my configuration --with-libxml-dir=/apps/libxml2-2.6.27

why is it not finding my config?

is there another tar im missing it seems the typical solution to this problem is solved using apt-get and installing the devel package except on this box i dont have access to apt-get and don't have the root access to install a package manually i can only use tarballs

It's looking for the xml2-config file which should be installed in the bin directory of the libxml2 prefix. Typically, this would be /usr/local/bin or /usr/bin. In your case it would be in /apps/libxml2-2.6.27/bin.

xml2-config determines the compile and linker flags that should be used to compile and link programs that use libxml2. That being the case, it is probably part of the libxml2 development package rather than the runtime package you installed. Look for and install a package libxml2-dev or libxml2-devel. After you install the development files, try the PHP install again.

there doesn't seem to be a /bin under /apps/libxml2-2.6.27/ however there is an xml2-config file in that directory thats why i'm confused why it cant find it

as i mentioned befor i cannot install packages on this machine i can only use tar files. adn there dosent appear to be a libxml2-2.6.27-devel.tar file on the main site.

figured it out . the configure file looks in prefix/bin/ for the xml2-config

for some reason when i made libxml it didn't create a /bin/ after editing the php it finds that file.

Sorry, didn't read that last paragraph closely enough. If you're using tarballs, then your getting everything that would be in the development package. Now I have to download the PHP tarball and read the configure script...

Here's the applicable section from the configure script

Code:

for i in $PHP_LIBXML_DIR /usr/local /usr; do
    if test -x "$i/bin/xml2-config"; then
      ac_cv_php_xml2_config_path="$i/bin/xml2-config"

You can see that the script looks in the bin subdirectory of the user supplied libxml2 prefix, then /usr/local, then /usr for xml2-config. Since you don't have a bin subdirectory, it can't find xml2-config.

There's two things you could do at this point. Either create /apps/libxml2-2.6.27/bin and move xml2-config there or edit the PHP configure script to NOT look in the bin subdirectory. This sed will edit the configure script

Code:

sed -i 's@/bin/xml2-config@/xml2-config@g' configure

Edit: Which you figured out while I was writing this post.

yep got it just as you were writing thanks for the info though, your explination was much more detailed and may help someone else who might be in the same boat.
