- SciTech Software Distribution - Standard Directory Structure
- ------------------------------------------------------------
-
- This file describes the general directory structure of the SciTech Software
- programming libraries that you have installed. This directory structure
- is common to all SciTech Software products.
-
- Find a nice home for it all
- ---------------------------
-
- Before you install any of SciTech Software Products, you should decide upon
- a standard root directory for installing all of the products into. The
- default that we use is under the \SCITECH directory of one of our hard drives
- (in my case C:). Then you should install all the files for all the
- distributions that you have under the same directory tree. Many of the
- products use common libraries to get things done (like the PMODE library)
- and common header files. When you install them into the same directory
- you will only have one copy of each of these common files.
-
- IMPORTANT: Once you decided on a root directory for installing your SciTech
- Software Products, you should install them all into the same
- directory. The command to do this with PKZIP would be (assuming
- that all products are installed under C:\SCITECH):
-
- pkunzip -d <zipfile>.zip C:\SCITECH
-
- This will correctly unzip all the archived files and create the
- correct directory structure under the root directory C:\SCITECH
-
- Note that the '-d' command line option is essential to ensure
- that the correct directory structure is built.
-
- Installing for use
- ------------------
-
- Once you have created the directory structure for the distribution, and
- all files have been installed, you will need to perform two final steps
- before you can use the libraries:
-
- 1. Change your compilers default include path to include the
- d:\SCITECH\INCLUDE directory so your compiler can find the required
- include files, where d: is the drive that you have installed the
- software onto.
-
- 2. Change your compilers default library path to include the
- d:\SCITECH\LIB\??? directory (substitute the correct sub-directory
- name for your compiler - d:\SCITECH\LIB\BC3 is for Borland C++ 3.1).
-
- Once you have done this, you can simply start using the library files as
- provided. If you intend to re-compile any of the libraries from the
- provided source code, you will need to follow the steps in the next
- section.
-
- SciTech Software Common Makefile Utilities
- ------------------------------------------
-
- In order to be able to re-compile any of the SciTech Software Distributions
- that come with source code, you will also need to install the SciTech
- Software Common Makefile Utilities package. This can be found in the
- archive called MKUTIL??.ZIP from the same location that you obtained this
- package from. This archive contains all of the relevant executable files
- (including a copy of DMAKE 3.8), batch files and DMAKE startup files
- required to re-compiled the source code for any of the supported compilers.
-
- Once you have installed the files onto your hard drive, you will need to
- perform the following steps:
-
- 1. Change the default executable file path in your AUTOEXEC.BAT file
- to include the d:\SCITECH\BIN directory. This should be placed
- at the START of your path, so that the MAKE.EXE file in the BIN
- directory will be found first, rather than your compilers usual
- make utility.
-
- 2. Set the environment variables SCITECH and MGL_ROOT (if you are using
- the MegaGraph Graphics Library). The batch file MGL_ENV.BAT in
- the root \SCITECH directory is a sample of this. The SCITECH
- environment variable is used by the batch files in the BIN
- directory for setting up for compiling with a particular compiler,
- and by the DMAKE program so that it can find all of the relevant
- files during compilation.
-
- 3. Set up the enivornment variables needed by the bacth files in the
- next step, so that they can located your compilers executable files,
- include files and library files. The file BIN\SET-VARS.BAT is an
- example that we use, so you can start with this to build you own
- batch file.
-
- 4. Run the relevant batch file to set the environment up for your
- compiler. The will file begin with a two letter prefix, and
- end in either 16-VAR.BAT or 32-VAR.BAT (depending on whether you will
- be compiling for 16 or 32 modes). These files require the SCITECH
- environment variable to setup correctly, and the relevant variables
- from the previous step to be set up correctly.
-
- The following compilers are usually supported by SciTech Software, along with
- the code used by the batch files from step 4 above (some libraries may not
- support a particular compiled depending on lanuage requirements):
-
- bc3 - Borland C++ 3.1 16 bit
- bc16 - Borland C++ 4.0 16 bit
- bc32 - Borland C++ 4.0 32 bit
- vc16 - Microsoft Visual C++ 1.
- vc32 - Microsoft Visual C++ 1.
- sc16 - Symantec C++ 6.1 16 bit
- sc32 - Symantec C++ 6.1 32 bit
- wc16 - Watcom C++ 10.0 16 bit
- wc32 - Watcom C++ 10.0 32 bit
- hc32 - Metaware High C/C++ 3.2
- dj32 - DJGPP GNU C/C++ 32 bit
-
- Once you have everything set up correctly, you should simply be able to
- type MAKE in any of the source directories and be in business.
-
- Compiling with Optimisations or for Debugging
- ---------------------------------------------
-
- By default when you build the libraries, not optmisations and no debugging
- information is generated. You can turn either (or both) of these features
- on by setting the OPT or DBG variables for DMAKE. You can do this either
- by passing them on the command line, or setting them as environment
- variables:
-
- make OPT=1 DBG=1
-
- or
-
- set OPT=1
- set DBG=1
- make
-
- Changing the default DOS Extender
- ---------------------------------
-
- All of the SciTech Software libraries are DOS Extender independant. All
- DOS extender dependant information is encapsulated in the PMODE.LIB library.
- The default library provided for each of the compilers is compiled for
- the default DOS extender normally used by that compiler. All you need to
- do in order to use a different DOS extender is re-compile the PMODE
- library with the appropriate command line options, and then link with
- this new library. Refer to the documentation on the PMODE library for
- more details.
-
- All SciTech Software distributions that require the PMODE library, come
- with a pre-compiled version of the library for the default DOS extender
- used by that compiler. If you wish to change the DOS extender, or you
- wish to have a look at the source code, you will need to obtain the
- PMODE library source archive. You should be able to get this from the
- same site that you downloaded this archive from as the file PMLITE??.ZIP.
-

- The following is a brief outline of the directory tree, and the contents of
- all the sub-directories (note that not all of these will be present in
- every SciTech Software Distribution archive):
