- The gif_lib library and utilities has been successfully compiled on the
- following platforms (you will need ansi c compiler for that):
-
- 1. IBM-PC, using Turbo C version 2.0/Borland C++ 2.0.
- 2. Sun 3, with O.S. 3.5 and O.S. 4.0.3, using gcc (gnu c compiler).
- 3. Sun 4, with O.S. 4.1.1, using gcc (gnu c compiler).
- 4. HP workstations, running unix BSD4.3, using gcc (gnu c compiler).
- 5. SGI personal iris (iris4d) running IRIX 4.3, using its cc.
- 6. IBM R6000 running aix, using xlc (Ansi C compiler).
-
- The first one (IBM-PC) was the main target of this package. The unix version
- compiles all the device independent utilities and more (such as gif to rle
- conversions, gif2x11 etc.). The IBM-PC compilation and testing is different
- from the unix ones, and are described in seperated section below.
-
- Compile and test - IBM PC
- -------------------------
-
- O.k. if you have TC/BC you are in good shape (otherwise you are on your own)
- and compilation will be simple:
-
- 1. Goto to the makefiles in .\lib and .\util (called makefile.tc in both
- places) and change the variable CC_LIBS to the exact place you have your
- cc libraries. I use to put them in ram disk (disk f:) for fast access.
- Make sure this is short variable or otherwise dos will complain about
- lines too long (the stupid 128 chars per line), in linkage...
- 2. Few of the utilities on .\util needs the TC graphic libraries (the gif2xxxx
- utilities). You need to create a library named graphbgi.lib that holds all
- the BGI drivers and CHR fonts. You do so by a sequence similar to:
-
- a. bgiobj herc (bgiobj.exe is on one of your TC 2.0 diskettes).
- b. bgiobj egavga
- c. bgiobj cga
- d. bgiobj ibm8514
- e. bgiobj pc3270
- f. bgiobj goth
- g. bgiobj litt
- h. bgiobj sans
- i. bgiobj trip
-
- This will convert all this drivers/fonts into .OBJ files, which can be all
- linked to creat the library:
-
- tlib graphbgi.lib +herc.obj +egavga.obj ... +trip.obj, graphbgi.lst
-
- Copy this library to the same directory as specified by CC_LIBS in 1.
-
- 3. Decide what directory you want the executables to br copied to and create
- it if it is new. Goto .\util and set the DEST variable in the makefile
- (makefile.tc) to that directory.
- 4. Fire the compilation by executing make-ibm.bat
-
-
- To test most of the utilities reconfigure test-ibm.bat as follows:
- 1. make sure the new exectuables directory is in your path variable.
- 2. The default display program is gif2bgi (in this package). If may want
- to change its setup. See ./doc/gif2bgi.doc for more.
- 3. Set the GIF_DIR variable in the batch file to the absolute path of
- ./pic directory (hold some gif examples).
-
- Run test-ibm.bat. You will want to print gif2bgi.doc in ./doc so you will
- know how to use it (at list how to exit...).
-
-
- Compile and test - UNIX
- -----------------------
-
- Compiling are testing under unix is simpler than the IBMPC:
-
- 1. If you are to use the unix unzip utility to unpack this library, you
- need to use the -d flag to enforce creation of subdirectories. The
- following subdirectories are to be created: bin doc lib pic util.
- But I guess you are after this if you are reading this file now...
- 2. You need to convert all files (almost - gif2X11.* has X capitalized), from
- MSDOS convension to unix one. This involves converting to lower case, and
- stripping off ^Z from end of file and CR from CR/LF end of line.
- You can do it manually, However the DOS2UNIX script will do %99 of the job.
- It will convert ALL files found in subdirectories of the current working
- directory from upper case to lower case, and strip the CR from the CR/LF
- end of line used by MSDOS and ^Z from end of file. It does not check if
- the file is binary or a text one, and it will DESTROY the gif images in
- ./pic/*.gif, as it will strip off any CR or ^Z in them. You better move
- the ./pic directory to someplace else before invoking DOS2UNIX and move it
- back afterwords. Also you will probably need to issue 'chmod +x dos2unix'
- to make it executable.
- MAKE SURE no other files but from this unpacked library, exists in the
- current and sub directories, and execute dos2unix.
- 3. Go to the ./lib and ./util directories (they should be lower case, after
- dos2unix has been executed), and edit the unix makefiles (makefile.unx)
- for the following:
- a. Set CC to your c compiler name (usually cc but can be gcc - see in the
- makefile.unx).
- b. Select the right flags to the c compilers. Flags for SGI cc, and gcc are
- provided.
- 4. Fire the compilation using make-unx. This will leave the executables in
- ./bin.
-
- Test the package by adding ./bin to your path and firing the 'test-unx' script.
- This assumes the display is X11, and the environment variable DISPLAY is set
- properly - uses gif2X11 as display utility.
