udata: Low level ICU data
This sample demonstrates
Using the low level ICU data handling interfaces (udata) to create
and later access user data.
Files:
writer.c C source for Writer application, will generate data file to be read by Reader.
reader.c C source for Reader application, will read file created by Writer
udata.sln Windows MSVC workspace. Double-click this to get started.
udata.vcproj Windows MSVC project file
To Build udata on Windows
1. Install and build ICU
2. In MSVC, open the workspace file icu\samples\udata\udata.sln
3. Choose a Debug or Release build.
4. Build.
To Run on Windows
1. Start a command shell window
2. Add ICU's bin directory to the path, e.g.
set PATH=c:\icu\bin;%PATH%
(Use the path to where ever ICU is on your system.)
3. cd into the udata directory, e.g.
cd c:\icu\source\samples\udata\debug
4. Run it
writer
reader
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).
To Build on Unixes
1. Build ICU.
Specify an ICU install directory when running configure,
using the --prefix option. The steps to build ICU will look something
like this:
cd <icu directory>/source
runConfigureICU <platform-name> --prefix <icu install directory> [other options]
gmake all
2. Install ICU,
gmake install
3. Compile
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.)
cd <icu directory>/source/samples/udata
gmake ICU_PATH=<icu source directory> ICU_PREFIX=<icu install directory)
To Run on Unixes
cd <icu directory>/source/samples/udata
gmake ICU_PREFIX=<icu install directory> check
-or-
export LD_LIBRARY_PATH=<icu install directory>/lib:.:$LD_LIBRARY_PATH
writer
reader
Note: The name of the LD_LIBRARY_PATH variable is different on some systems.
If in doubt, run the sample using "gmake check", and note the name of
the variable that is used there. LD_LIBRARY_PATH is the correct name
for Linux and Solaris.
