Double-click this to get started. 15 udata.vcproj Windows MSVC project file 16 17 To Build udata on Windows 18 1. Install and build ICU 19 2. In MSVC, open the workspace file icu\samples\udata\udata.sln 20 3. Choose a Debug or Release build. 21 4. Build. 22 23 To Run on Windows 24 1. Start a command shell window 25 2. Add ICU's bin directory to the path, e.g. 26 set PATH=c:\icu\bin;%PATH% 27 (Use the path to where ever ICU is on your system.) 28 3. cd into the udata directory, e.g. 29 cd c:\icu\source\samples\udata\debug 30 4. Run it 31 writer 32 reader 33 IMPORTANT: On some systems, the reader and writer executables may not be in the same directory. If this is the case, this will likely cause a problem with reader looking for the .dat file in the wrong directory). 34 35 To Build on Unixes 36 1. Build ICU. 37 Specify an ICU install directory when running configure, 38 using the --prefix option. The steps to build ICU will look something 39 like this: 40 cd <icu directory>/source 41 runConfigureICU <platform-name> --prefix <icu install directory> [other options] 42 gmake all 43 44 2. Install ICU, 45 gmake install 46 47 3. Compile 48 You will need to set ICU_PATH to the location of your ICU source tree, for example ICU_PATH=/home/srl/icu (containing source, etc.) 49 cd <icu directory>/source/samples/udata 50 gmake ICU_PATH=<icu source directory> ICU_PREFIX=<icu install directory) 51 52 To Run on Unixes 53 cd <icu directory>/source/samples/udata 54 gmake ICU_PREFIX=<icu install directory> check 55 -or- 56 57 export LD_LIBRARY_PATH=<icu install directory>/lib:.:$LD_LIBRARY_PATH 58 writer 59 reader 60 61 Note: The name of the LD_LIBRARY_PATH variable is different on some systems. 62 If in doubt, run the sample using "gmake check", and note the name of 63 the variable that is used there. LD_LIBRARY_PATH is the correct name 64 for Linux and Solaris. 65 66
