Using LEADTOOLS with Your C/C++ Compiler

Using LEADTOOLS with Your C++ Compiler

For Microsoft C, include the library (.LIB) files that LEADTOOLS supplies in order to call LEADTOOLS functions. For a summary of the library files, refer to Files To Be Included With Your Application. For the library files required by a particular function, refer to the function description.

For other compilers, you may need to generate a .LIB file from a DLL. For example, use the IMPLIB.EXE program with Borland C, versions 3.x and 4.x. 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.

On WIN32 systems, you should also specify alignment on a 1-byte boundary.

The make files for the example programs are different for different editions of LEADTOOLS, as follows:

For WIN32 editions, all of the example programs have separate make files for Microsoft C.

To use the LEADTOOLS C++ Class Library, perform 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);
…
}
