In the axis2c\build\win32\configure.in file, the following line indicates that iconv version 1.9.2 is expected.
ICONV_BIN_DIR = E:\iconv-1.9.2.win32 however the rest of the documentation refers to iconv version 1.9.1. Which iconv version is the right one? build works fine with either version, but I am get an access violation on launch of axis2_http_server.exe in both cases. This problem may be unrelated however so I will continue troubleshooting.
