I get the following error 开发者_开发百科 message while buliding PHP on AIX5.2:

"checking whether libxml build works... no",

and actually I have installed libxml2 and libxml2-devel,

What could be the problem?

Thank you!

(I check the config.log, and the last part of the message says:

configure:21603: checking whether libxml build works configure:21630: gcc -o conftest -O -xs -xstrconst -zlazyload -L/opt/freeware/lib -L/opt/freeware/lib conftest.c

      -lxml2 -lz -liconv -lm 1>&5

include "confdefs.h"

char xmlInitParser();
int main() {

  return 0;
}

) could some one tell me what happened? thank you !

Check your config.log for the specific error. configure just tries to compile a test program using libxml. If it doesn't compile, it considers that libxml doesn't work.

During ./configure, it should output where its finding libxml's install directory - what does that say?

On my AIX 5.2 box, I have these two installed:

libxml2-2.6.21-4
libxml2-devel-2.6.21-4

And they live in /usr/opt/freeware/lib/libxml2.a, but there is a symlink in /usr/lib pointing back to the library (includes are done similar)

/usr/lib/libxml2.a -> ../../opt/freeware/lib/libxml2.a

So configure can find them. The RPM package should have made the symlinks. Maybe yours are missing so it can't find the path to libxml?

You could build your own (later) version of libxml, and install that somewhere (usually /usr/local). The prebuilt RPM is pretty outdated anyways.

You can also use --with-libxml-dir=<path> to point to the install dir directly. --with-libxml-dir=/opt/freeware/ should work.
