Hello Sorin, Thanks for your reply.
I tried the below two - 1. I had earlier downloaded Xerces from http://xml.apache.org/dist/xerces-c/3/binaries/xerces-c-3.1.1-x86_64-windows-vc-10.0.zip It had xerces-c_3.lib and xerces-c_static_3.lib. The file names indicated that these are 64-bit binaries. I added the below in httpd.conf file - LoadFile e:/xerces-c-3.1.1-x86_64-windows-vc-10.0/xerces-c-3.1.1-x86_64-windows-vc-10.0/lib/xerces-c_3.lib Tried to start httpd.exe and got the below error - e:\httpd-2.4.4-win64\Apache24\bin>httpd.exe httpd.exe: Syntax error on line 173 of E:/httpd-2.4.4-win64/Apache24/conf/httpd.conf: Cannot load E:/xerces-c-3.1.1-x86_64-windows-vc-10.0/xerces-c-3.1.1-x86_64-windows-vc-10.0/lib/xerces-c_3.lib into server: %1 is not a valid Win32 application. If I try to load xerces-c_static_3.lib also I get the same error. 2. I downloaded the Xerces source code from http://xml.apache.org/dist/xerces-c/3/sources/xerces-c-3.1.1.zip and built it using Visual Studio 2010 as a 64-bit target. This generated xerces-c_3D.lib. Changed httpd.conf file, LoadFile E:/xerces-c-3.1.1/xerces-c-3.1.1/Build/Win64/VC10/Debug/xerces-c_3D.lib Tried to start httpd.exe and got the same error. httpd.exe: Syntax error on line 173 of E:/httpd-2.4.4-win64/Apache24/conf/httpd.conf: Cannot load E:/xerces-c-3.1.1/xerces-c-3.1.1/Build/Win64/VC10/Debug/xerces-c_3D.lib into server: %1 is not a valid Win32 application. Kindly advice. Thanks.
