Hi, I'm trying to build php 5.2.1 on windows and am hitting the following problem at link time .... Creating library Release\php5ts.lib and object Release\php5ts.exp libxml.obj : error LNK2019: unresolved external symbol _xmlDllMain referenced in function _DllMain@12 Release\php5ts.dll : fatal error LNK1120: 1 unresolved externals NMAKE : fatal error U1077: '"C:\Program Files\Intel\CPP\Compiler81\IA32\bin\icl. exe"' : return code '0x460' I am linking it to a libxml2.lib that I have compiled. When I do a dumpbin i do not see the _xmlDllMain symbol. I tried downloading some libxml2 binaries but they didn't have that symbol either. Would appreciate some help on this issue. Thanks, Rashmi
