Using LEADTOOLS with Your C/C++ Compiler

Using LEADTOOLS with Your C++ Compiler

To use the LEADTOOLS Class Library you have to go through the following steps:

1	Link your application to the LIB file for the class library which is LTWVC_u.lib for MSVC compilers and LTWEN_BC.LIB for Borland compilers.
2	At the start of your application load the desired set of LEAD libraries by calling:

LBase::LoadLibraries(L_UINT32 uLibrary); with flags indicating which libraries to load. For example to load LEAD LTKRN15u.dll library:

WinMain()
{
…

LBase::LoadLibraries(LT_KRN);
…
}

For Microsoft C, you need to include the Class Library .LIB file that LEADTOOLS supplies in order to use the LEADTOOLS Class Library objects. For a summary of the library files, refer to Files To Be Included With Your Application. For the library files required by a particular class, refer to the class description.

For other compilers, you may need to generate a .LIB file from the Class Library .DLL. For example, use the IMPLIB.EXE program with Borland C. For other compilers, on WIN32 systems,you should also specify alignment on a 1-byte boundary, Check the “Treat enum types as ints” checkbox found in the “Project->Options->Compiler” tab, and add “FOR_BORLAND” to the conditional defines found in the “Project->Directories/Conditionals” tab.
