| Jan 21, 2003 - [Bug 16277] Readme should make note of threaded library problems in BCB6 |
| ===================================================================================== |
| There's another known problem with BCB6 to do with linking single-threaded |
| applications to DLLs. Specifically, DLLs are normally linked to the |
| multithreaded runtime DLL (CC3260MT.dll); however, if an application is linked |
| to the single-threaded DLL (CC3260.dll) and consequently attempts to free memory |
| allocated by the MT DLL there will be an memory access violation. In particular |
| this causes problems when using the transcoding utilities that return allocated |
| memory (which the sample programs use). |
| |
| Currently there appears to be no way of forcing an application to be linked |
| against the MT version of the runtime, therefore it is recommended that the |
| versions of utilities which accept pre-allocated buffers be used. |

| Feb 7, 2002 - Xerces C and Borland C++Builder6 |
| ============================================== |
| |
| The enclosed project file no longer produce a Xerces library that is dependent upon |
| the Borland memory manager (borlndmm.dll). However there is still a dependency upon |
| the multi-threaded C++ Run Time Library. The RTL is named cc3260mt.dll and is |
| included in this distribution for your convenience. |
| |
| The supplied project files support Borland C++Builder6. The overwhelming size of the |
| Xerces project will cause some problems for the new IDE. The version 6 IDE appends |
| the source file directories to the include and lib paths, even though it is not |
| necessary. The resulting project file becomes corrupted due to the unnatural line |
| lengths. The file cannot be edited by hand to correct the situation, as the IDE will |
| simply "fix" the paths for you when it opens the project. This will discovered late |
| in BCB6 field test, at a point in time when it was impossible to alter the project |
| options dialog box. A work around was to have the IDE check a registry entry that |
| would prohibit it from modifying paths. Set the following value in the registry: |
| |
| [HKEY_CURRENT_USER\Software\Borland\C++Builder\6.0\Globals] |
| "DontManagePaths"="1" |
| |
| or simply double click on the .reg file in this directory. |
