I compiled log4cxx on my computer,(os:xp, IDE:vs2008)
I have 4 project folders in one same directory,(apr,apr-util,apr-iconv,apache-log4cxx),and open apache-log4cxx dsw and set it as startup and build.
apr,apr-util , log4cxx and xml are all compiled successfully, but when linking,it occurs errors below.
I try to add apr-iconv/include dir to log4cxx,but it dosen't matter. why?

Answer:
did you run configure-aprutil.bat ?
there is no sed util on windows by default, so it probably did notheng, then try to do it with your own hands
sed -i -e "s/#define APU_HAVE_APR_ICONV\b.*/#define APU_HAVE_APR_ICONV 0/" ..\apr-util\include\apu.hw
sed -i -e "s/#define APR_HAS_LDAP\b.*/#define APR_HAS_LDAP 0/" ..\apr-util\include\apr_ldap.hw
it means find the macro definition of APR_HAS_LDAP, APU_HAVE_APR_ICONV and set it to 0. originaly they are defined as 1.
