vc6 |-bin |-include |-libCopy the whole of lib and include directories from your VC98\ to your new tree. Then copy from the VC98\bin directory to your bin directory cl.exe, c1.dll, c1xx.dll, c2.dll, cvtres.exe, lib.exe, link.exe and nmake.exe Then copy from MSDev98\bin to your bin mspdb60.dll, rc.exe and rcdll.dll.Setup a vc6setup.bat file with the following to create a build environment
echo Setting environment for minimal Visual C++ 6 set MSVCDir=drive:\path\to\vc6 set INCLUDE=%MSVCDir%\include set LIB=%MSVCDir%\lib set PATH=%MSVCDir%\bin;%PATH% Title Minimal VC6 build shellYou can now open a new command shell and run the batch file to setup a build shell. To build tcl you can now cd to tcl\win and do
nmake -f makefile.vc OPTS=none releaseThe installation takes about 70MB disk space so can easily be put on a USB memory stick if needed.Once you have finished on the target system a simple rmdir /q /s vc6 will get rid of the whole lot.
With Platform SDKObviously under windows you should always build stuff with the most recent headers and libraries you can get - which means the Platform SDK - this is a free download from Microsoft. If you want to apply this to the minimal installation given above, you simply need to copy the Platform SDK include and lib directories on top of your minimal ones. The result is an up-to-date command-line build environment weighing in at about 100MB with no entries in the registry to worry about.APN 20101015 As per Pat Thoyts on the chat, if you are building with VC++ 6, you cannot use an SDK later than Feb 2003 SDK as the libraries supplied in later SDKs are not compatible with the VC++ 6 linker. Turns out this SDK is not visible on Microsoft's download pages but can still be downloaded from their servers. Copy the files

Or you could just extract the contents from the cab files and use the lib and include directories from there.http://download.microsoft.com/download/platformsdk/sdk/update/win98mexp/en-us/3790.0/FULL/PSDK-FULL.2.cab
IDEThe Visual studio IDE is also capable of being quite stand-alone. If you copy the MSDev98 directory from its normal location into the minimal VC6 tree (ie: to vc6\msdev98) you just need to set the MSDevDir environment variable and add %MSDevDir%\bin to the path to be away. (Remember to start msdev.exe from the command line so that it inherits the environment that lets it know where the compiler is installed.)
