Re: Latest version of Mozilla LDAP?

I have followed the steps in wiki and installed the components in
window 2003 server:
MozillaBuildSetup-Latest.exe
mozldap-6.0.7.tar.gz
nss-3.12.9-with-nspr-4.8.7.tar.gz

after I did the following:
cd mozilla/directory/c-sdk
./configure --with-nss --enable-clu [--enable-64bit]
make

it displays many errors:
eg.
d:\mozilla\directory\c-sdk\ldap\libraries\libprldap\ldappr-int.h(45) :
fatal err
or C1083: Cannot open include file: 'nspr.h': No such file or
directory

i cannot find any information for nspr.h in this discussion group
please tell me what is missing in the builds and how to fix?
how can i identify the building process is completed sucessfully?

beisdes, i had read 64bit build steps at
http://wiki.mozilla-x86-64.com/How_To_Build_Windows_x64_Build
but it seems to simple for a dummy like me
it there more inforamtion for building 64bit version?
