[jans0204 (jans0204)]

J005：AWKcc - awk-to-C transcompiler (PART B)

B. make libAWK.a

1. 抽取 awkcc-main.zip\awkcc-main\1988\orig\lib -> R:\_W_\lib\

2. 備份原檔 -> R:\_W_\lib\prog\

   cp awkrun.c
   cp ear.h
   mv makefile
   cp misc.c
   cp xprintf.c
   cp y.tab.h

   cp 表補釘。

3. 複製：stdarg.h

   copy R:\_W_\awkcc\stdarg.h R:\_W_\lib\

4.1 PATCH - ear.h LINE_55

   //extern char *malloc(), *realloc(), *calloc();
     extern void *malloc(), *realloc(), *calloc();

4.2 PATCH - awkrun.c

   LINE_98
   //extern int fpecatch();
     extern void fpecatch();

   LINE_716
   //fpecatch()
     void fpecatch()

4.3 PATCH - misc.c LINE_129

   //#include <varargs.h>
     #include "stdarg.h"

4.4 PATCH - xprintf.c LINE_13

   //#include <varargs.h>
     #include "stdarg.h"

4.5 PATCH - y.tab.h 依據 R:\_W_\awkcc\y.tab.h 修正 token id

   #define FINAL 268
   #define DOT 269
   #define ALL 270
   #define CCL 271
   #define NCCL 272
   #define CHAR 273
   #define OR 274
   #define STAR 275
   #define QUEST 276
   #define PLUS 277

   #define CAT 342   // same

4.6 編碼 makefile

   CC=gcc
   CFLAGS=-O

   SOURCES=misc.o lines.o make_str.o copystr.o index.o xprintf.o \
       isreg.o awkrun.o awkmod.o assignvars.o awkerr.o clear_htb.o \
       free_array.o clearctest.o delete.o docomp.o docompN.o \
       regexp.o newb.o awkparse.o filedrop.o fileget.o getd.o \
       getrec.o gsub.o n_insert.o s_insert.o insert.o make_array.o \
       make_buckets.o make_elem.o make_var.o member.o number.o \
       opennext.o pipeget.o printD0.o print_var.o resize.o \
       rgetrec.o setctest.o split.o split2.o split3.o splitrec.o \
       strsplitrec.o resplitrec.o sresize.o substr.o

   libAWK.a: $(SOURCES)
       ar -q libAWK.a $(SOURCES)
       ranlib libAWK.a

   clean:
       rm -f *.o

5.1 產生 libAWK.a

   進入 MSYS

   $ cd /r/_W_/lib
   $ make > make.log 2>&1
   $ nm -s libAWK.a > libAWK.idx
   $ make clean
   rm -f *.o

5.2 安裝：

   md R:\awkcc\lib
   mv libAWK.a R:\awkcc\lib
   md R:\awkcc\include
   cp *.h R:\awkcc\include
   del R:\awkcc\include\stdarg.h

6. 測試：

   下載 Hello_world_Text.awk -> R:\
   https://rosettacode.org/wiki/Hello_world/Text#AWK

   R:\set path=r:\awkcc\bin;%path%

   R:\>awkcc Hello_world_Text.awk
   R:\>set HEADERDIR=r:\awkcc\include
   R:\>set AWKLIB=r:\awkcc\lib\libAWK.a
   R:\>set MATHLIB=-lm
:: R:\>gcc -O -Ir:\awkcc\include -o a.out awker.c r:\awkcc\lib\libAWK.a -lm
   R:\>gcc -O -I%HEADERDIR% -o a.out awker.c %AWKLIB% %MATHLIB%
   R:\>strip a.out
   R:\>del awker.c

   R:\>a.out
   Hello world!

   R:\>
