They -are all summarized in change log comments at the beginning of the -changed files. All of the original files from f2c were checked in to -RCS before modification, so it is possible to see exactly what changes -were made, for the extremely curious. That precaution was also for my -benefit, in case I ever recompile the Fortran sources, and want to -make similar changes to that new C source code. - -Below is the README file for this directory included with the 1.3 -release of the LPC-10 package. A few parts of it are a little out of -date, but it is correct for the most part. - - -Sun Jul 7 15:30:31 CDT 1996 -Andy Fingerhut (jaf@arl.wustl.edu) - -To create the LPC-10 library, copy the appropriate makefile to the -proper name for easy use, e.g., for Unix, copy makefile.unx to the -file "Makefile". The file makefile.dos has been used with some -version of the 'nmake' utility that comes with the Microsoft C -compiler (the same one used for Nautilus v1.5a, which I believe -specifies Microsoft C version 7.0 or later). - -Then edit the file lpc10.h in the directory above. It should already -be set up to work properly on any Unix compiler for which "int" is 32 -bits and "short" is 16 bits, and under the Microsoft C compiler -configured so that "long" is 32 bits and "int" is 16 bits. There must -be a typedef for the two types INT32 and INT16 in that file. You -should choose types that compile to those sizes using your compiler, -because there are places in the LPC-10 code that expect INT16's to -have exactly 16 bits (at least, I *think* they must be no larger), and -INT32's to have exactly 32 bits. - - -A few notes on how these files were created -------------------------------------------- - -(This section is mostly for my benefit, so I can remember what I did. -You don't need to read it if you just want to use this package. It -might be useful to read it if you change the Fortran sources and want -to recreate a usable library of C sources. -- Andy) - -These C sources were created automatically from the Fortran sources -using f2c, for the most part. Listed below are the extra -modifications that were made after this automatic conversion. Many of -them were made so that it was not necessary to install f2c in order to -use this LPC-10 coder. - -1. - -Put all of those files that were necessary for only the coder, rather -than an application that uses the coder, into this subdirectory called -lpc10. - -2. - -Copied f2c.h from the f2c distribution into this subdirectory. Some -modifications were made to the "typedef" statements in this file, to -explicitly indicate the sizes (in bits) that different integer types -should be. The types INT32 and INT16 must be defined in a file called -lpc10.h in the directory above. Created the file f2clib.c, containing -only the functions pow_ii(), r_sign(), and i_nint() from the f2c -library. - -3. - -The f2c output originally had a file called contrl_com.c, that defined -a small structure containing a few variables that were used in many -different functions of the LPC10 code. Every file containing -functions that used it defined it as "extern", while contrl_com.c -actually allocated storage for the structure. Bill Dorsey, one of the -lead developers of Nautilus, said that the Microsoft C compiler had -problems either compiling this file, or linking it with all of the -other compiled files, so he just eliminated that file and removed the -"extern" keyword from the one of the files that declared it that way. -The file chosen (arbitrarily) was analys.c. - -4. - -Copied the makefiles for Unix and Microsoft C from the Nautilus v1.5a -distribution into the lpc10 directory. Modified them to take out -references to Nautilus. These makefiles don't create an executable, -but a library of compiled functions called liblpc10.a (Unix) or -LPC10.LIB (DOS). This library can be used when linking an executable -that calls the functions lpcini_(), lpcenc_(), and lpcdec_(). |
