citer: Character Iteration
|
||||
|
||||
This sample demonstrates
|
||||
Using ICU to determine the linguistic boundaries within text
|
||||
|
||||
|
||||
Files:
|
||||
citer.cpp Main source file in C++
|
||||
citer.dsw Windows MSVC workspace. Double-click this to get started.
|
||||
citer.dsp Windows MSVC project file
|
||||
|
||||
To Build citer on Windows
|
||||
1. Install and build ICU
|
||||
2. In MSVC, open the workspace file icu\samples\citer\citer.dsw
|
||||
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 citer directory, e.g.
|
||||
cd c:\icu\source\samples\citer\debug
|
||||
4. Run it
|
||||
citer
|
||||
|
||||
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
|
||||
cd <icu directory>/source/samples/citer
|
||||
gmake ICU_PREFIX=<icu install directory)
|
||||
|
||||
To Run on Unixes
|
||||
cd <icu directory>/source/samples/citer
|
||||
|
||||
gmake ICU_PREFIX=<icu install directory> check
|
||||
-or-
|
||||
|
||||
export LD_LIBRARY_PATH=<icu install directory>/lib:.:$LD_LIBRARY_PATH
|
||||
citer
|
||||
|
||||
|
||||
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.
