Error in compiling areaDetector

["GONG Yu" <gongyu@ihep.ac.cn>]

Hello everyone,
    I am running to the error when I compile the areaDetector module.
    The errors are listed below:

The products that have been built or installed are listed belows:
EPICS base 3.14.12.4
asyn4-25
synApps (autosave-5-1,busy-1-6,calc-3-2,sscan-2-9)
libtiff (tiff-4.0.4beta)
zlib (zlib-1.2.8)
libjpeg (libjpeg-turbo-1.4.0)
szip (szip-2.1)
hdf5 (hdf5-1.8.12)
My operating system is 32bit CentOS 5.6 

After this error, I install the libxml2 (libxml2, libxml2-devel and zlib-devel requied by libxml2-devel) by using RPM, then I rebuild the zlib and hdf5. But when I compile the areaDetector module, I still get the same error.
I do not know how to solve this problem, can anyone help me? 
Thank you,
