DOCUMENT:Q124157 08-AUG-2001 [winnt] TITLE :Cannot Build VC++ Projects (.PDB & .PCH Files) on Netware Server PRODUCT :Microsoft Windows NT PROD/VER:3.50 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 3.5 - Microsoft Windows NT Server version 3.5 ------------------------------------------------------------------------------- SYMPTOMS ======== When you try to a build Microsoft Visual C++ project on remote NetWare server from your Windows NT computer, one of the following error messages appear: Fatal error C2308: program database file, 'filename.pdb', has an obsolete format, delete it and recompile. -OR- Fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'msc1.cpp', line 1056) Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information. The errors do not occur if the project is on a local drive or on a remote Windows NT server. CAUSE ===== Windows NT has problem passing memory mapped file I/O to the NetWare redirector (NWRDR.SYS) and incorrectly writes the .PDB (program database) and .PCH (precompiled headers) files to NetWare servers. WORKAROUND ========== To work around this problem: You can work around Error C2308 by using the /Z7 compiler switch. This forces the compiler to keep the debugging information in the .OBJ files and not write it to .PDB files. You can work around Error C1001 by turning off the compiler option for the pre-compiled headers. To do this, select Settings from the Project menu, select C/C++, and turn off the compiler option in the Pre-compiled Headers dialog box. You can also work around the problem by building the .PDB file or .PCH file on a local drive, or by installing the latest U.S. Service Pack for Windows NT version 3.5. NOTE: After installing the latest U.S. Service Pack for Windows NT version 3.5, you will continue to receive error when you try to a build Microsoft Visual C++ project on remote NetWare server until you delete the incorrect .PDB and .PCH files. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT Workstation and Windows NT Server version 3.5. This problem was corrected in the latest U.S. Service Pack for Windows NT version 3.5.
