[Work] use nmake

use nmake from command prompt console window
*********************************************


If you open the command prompt console window from within the IDE by
using the menu item:

Tools->Visual Studio 2008 Command Prompt

============================================================================
The compiler has to know the path(s) to the header files (such as stdio.h).

There are a number of ways this can be specified. Normally it is specified
via an environment variable - INCLUDE=

The linker also has to know the path(s) to the lib files to be linked.
Again, there are a number of ways this can be specified.
Normally it is specified via an environment variable - LIB=

If you open the command prompt console window from within the IDE by
using the menu item:

Tools->Visual Studio 2008 Command Prompt

these environment variables will be set up for you automatically.

The file vcvars32.bat is where these are configured for 32-bit builds.
It's in the VC++ bin directory.

You can also specify the include file directory via the /I switch when
invoking cl.exe - type cl /? to see all of the options available. Note
the linker options as well.

As a self-professed "absolute beginner" you would be well-advised to
use the IDE for doing your programming. It will configure many things
for you - especially if you use the supplied project templates. There
are many things you have to consider when building using the command
line tools, which most beginners won't be able to cope with initially.

[Work] Visual Studio Linker tools errors

Linker Tools Warning LNK4098

defaultlib "library" conflicts with use of other libs; use /NODEFAULTLIB:library

You are trying to link with incompatible libraries.

Important The run-time libraries now contain directives to prevent mixing different types. You’ll receive this warning if you try to use different types or debug and non-debug versions of the run-time library in the same program. For example, if you compiled one file to use one kind of run-time library and another file to use another kind (for example, single-threaded versus multithreaded) and tried to link them, you’ll get this warning. You should compile all source files to use the same run-time library. See the Use Run-Time Library (MD, /ML, /MT, /LD) compiler options for more information.

You can use the linker’s /VERBOSE:LIB switch to determine which libraries the linker is searching. If you receive LNK4098 and want to create an executable file that uses, for example, the single-threaded, non-debug run-time libraries, use the /VERBOSE:LIB option to find out which libraries the linker is searching. The linker should print LIBC.LIB and not LIBCMT.LIB, MSVCRT.LIB, LIBCD.LIB, LIBCMTD.LIB, or MSVCRTD.LIB as the libraries searched. You can tell the linker to ignore the the incorrect run-time libraries by typing the incorrect libraries in the Ignore Libraries text box on the Link tab of the Settings dialog box in Developer’s Studio or by using the /NODEFAULTLIB:library option with LINK for each library you want to ignore. See the Ignore Libraries (/NODEFAULTLIB) linker option for more information.

The table below shows which libraries should be ignored depending on which run-time library you want to use.
To use this run-time library Ignore these libraries
Single-threaded (libc.lib) libcmt.lib, msvcrt.lib, libcd.lib, libcmtd.lib, msvcrtd.lib
Multithreaded (libcmt.lib) libc.lib, msvcrt.lib, libcd.lib, libcmtd.lib, msvcrtd.lib
Multithreaded using DLL (msvcrt.lib) libc.lib, libcmt.lib, libcd.lib, libcmtd.lib, msvcrtd.lib
Debug Single-threaded (libcd.lib) libc.lib, libcmt.lib, msvcrt.lib, libcmtd.lib, msvcrtd.lib
Debug Multithreaded (libcmtd.lib) libc.lib, libcmt.lib, msvcrt.lib, libcd.lib, msvcrtd.lib
Debug Multithreaded using DLL (msvcrtd.lib) libc.lib, libcmt.lib, msvcrt.lib, libcd.lib, libcmtd.lib

For example, if you received this warning and you want to create an executable file that uses the non-debug, single-threaded version of the run-time libraries, you could use the following options with the linker:

/NODEFAULTLIB:libcmt.lib /NODEFAULTLIB:msvcrt.lib /NODEFAULTLIB:libcd.lib /NODEFAULTLIB:libcmtd.lib /NODEFAULTLIB:msvcrtd.lib

[Work] How to set the path in Windows 2000 / Windows XP

Reference number: CH000549
How to set the path in Windows 2000 / Windows XP.
Question:

How to set the path in Windows 2000 / Windows XP.
Additional information:

Modifying the path statement will enable an MS-DOS window opened in Microsoft Windows as well as older programs to locate files that may be required to run the program.

Users familiar with MS-DOS will remember the PATH= statement that was in the autoexec.bat file. Additional information about the MS-DOS path command that is still usable in Windows 2000 and Windows XP can be found on our path command page, additional information about the MS-DOS command can be found on our set command page.

See our dictionary path definition for additional information about this term and related definitions.
Answer:

The path is now managed by Windows 2000 / Windows XP and not the autoexec.bat or autoexec.nt files. To change the system environment variables, follow the below steps.

1. From the desktop, right-click My Computer and click properties.
2. In the System Properties window, click on the Advanced tab.
3. In the Advanced section, click the Environment Variables button.
4. Finally, in the Environment Variables window, highlight the path variable in the Systems Variable section and click edit. Add or modify the path lines with the paths you wish the computer to access. Each different directory is separated with a semicolon as shown below.

C:\Program Files;C:\Winnt;C:\Winnt\System32
