Some notes on building UnixODBC on Microsoft Interix First use the modified configure and config.guess included in the Interix directory, copy them up into the main directory. Then build with the following line CFLAGS="-D_ALL_SOURCE -I/usr/local/include" CPPFLAGS="-D_ALL_SOURCE -I/usr/local/include" LDFLAGS="-L/usr/local/lib" ./configure After running configure, copy libtool from the Interix directory into the build directory Thanks to the MS group for supplying this info. Thats all for now. Nick.
