- Read this file before trying to compile miniGenericApp.
-
-
- Just when you thought it was easy to program in THINK C -- not
- all THINK C's are created equally. As a matter of fact, they're
- all different in subtle ways. Read On.
-
- Version 4.0 of THINK C supports the so-called "ANSI" standard
- definition of the C language. Previous versions of the
- Compiler don't. Therefore, header files and libraries that
- existed in earlier versions of Lightspeed don't exist anymore.
- The obvious advantage to this is that it's easier to write
- portable code, i.e., code that will compile and run on non-
- THINK C compilers that also support ANSI.The major disadvantage
- is that you need to make slight changes to source of Generic App
- depending on whether you're using Version 2, 3, or 4 of the
- compiler.
-
-
- Thus header file names changed between versions. Also, beginning with
- version 3.0, a slick, new feature called MacHeaders was introduced.
- When the MacHeaders option is selected, the compiler uses a binary file
- that describes all about Mac related data types, meaning that you
- don't have to include those manager header files that define fundamental
- Mac data structures like Event Records, WindowRecords, and the lot.
-
- Also between version 2 and 3, Multifinder became functional.So version
- 3 supports Multifinder while version 2 doesn't. There really are a lot of
- changes between the three versions.
-
- Because I want you folks out there to have running versions
- of Generic App, no matter what version of the compiler that
- you happen to own, I've devised a strategy that should allow everyone
- to use Generic (for the time being--I want you all to upgrade if you're going
- to continue with us and use the code examples. These three parts of Generic
- will be the only code that's written with this accomodation. (BTW, Symantec
- isn't paying me a commission for my one-man upgrade promotion but,
- perhaps they ought to offer a discount to my MacUser readers!)
-
- Here's how you get Generic to work on your compiler:
-
- First: Find out what version of THINK C that you're running.
-
- Next, there are three project files, one for version 2, 3, and 4 of
- THINK C. You use the one that's appropriate for your compiler. Then,
- we'll let the preprocessor to fixup the code for you through the
- use of a defined constant. This constant is in the file "Version.h" so
- open that file right now. It's in the miniGenAppHdr folder, with all
- the other header files.
-
- Step-by-step, here's what you do:
-
- For those of you who are running THINK C version 4.0:
-
- 0. Open project file miniGenAppπ-v4.0
- 1. change #undef V4 to #define V4 in Version.h.
- 2. make sure that you undefine V3 and V2.
- 3. Rename the resource file miniGenAppπ.rsrc
- to miniGenAppπ-v4.0.rsrc
- 4. Bring the Project "Up to Date"
-
- For those of you running version THINK C 3.01:
-
- 0. Open project file miniGenAppπ-v3.01
- 1. change #undef V3 to #define V3 in Version.h
- 2. make sure that you undefine V2 and V4.
- 3. Rename the resource file miniGenAppπ.rsrc
- to miniGenAppπ-v3.01.rsrc
- 4. Bring the Project "Up to Date"
-
- For those of you running versions Lightspeed 2.13 or 2.15:
-
- 0. Open project file miniGenAppπ-v2.13
- 1. change #undef V2 to #define V2 in Version.h
- 2. make sure that you undefine V3 and V4.
- 3. Rename the resource file miniGenAppπ.rsrc
- to miniGenAppπ-v2.13.rsrc
- 4. Run the project
-
- For those of you running anything else:
-
- 1. Isn't it time that you catch up with the rest of us?
-
-
- After we finish Generic App, all examples will
- be in THINK 4.0, period. There are a few
- good reasons for this, and you'll discover them
- as we get there. So please, anyone who is not
- using the latest version of the compiler,
- may we suggest that you THINK about upgrading?
-
-
- All the best,
