UbuntuのOpenCOBOLでソースをコンパイルして実行


インストールはUbuntuにOpenCOBOLをインストールする - developer's diaryにも書いたけどもapt-getでできました。

sudo apt-get install open-cobol


コンパイルするソースは、OpenCOBOL マニュアル - はじめにより。

       IDENTIFICATION DIVISION.
       PROGRAM-ID. hello.
       PROCEDURE DIVISION.
       DISPLAY "Hello World!".
       STOP RUN.

そしてコンパイル。

[xxx@/src/cobol]$ cobc -x hello.cob 
/tmp/cob2662_0.c: In function ‘hello_’:
/tmp/cob2662_0.c:75: warning: dereferencing type-punned pointer will break strict-aliasing rules
/tmp/cob2662_0.c:76: warning: dereferencing type-punned pointer will break strict-aliasing rules
/tmp/cob2662_0.c:77: warning: dereferencing type-punned pointer will break strict-aliasing rules

/tmp/cob2662_0.c:111: warning: dereferencing type-punned pointer will break strict-aliasing rules

ワーニングは出たのですが、

[xxx@/src/cobol]$ ls
hello  hello.cob

実行バイナリがあったので実行してみました。

[xxx@/src/cobol]$ ./hello
Hello World!

ちなみにcobcのman

OPEN-COBOL(1)                                                    OPEN-COBOL(1)

NAME
       open-cobol - COBOL compiler

SYNOPSIS
       cobc [options] files...
       cobcrun  program [ arguments to program ]

DESCRIPTION
       This manual page documents briefly the cobc and cobcrun commands.

       cobc is the COBOL compiler.

       cobcrun is a driver program to run COBOL programs compiled as modules.

OPTIONS
       The  cobc  program follows the usual GNU command line syntax, with long
       options starting with two  dashes  (`-').   A  summary  of  options  is
       included below.  For a complete description, see the Info files.

       -h, --help
              Show summary of options.

       --version
              Show version of program.
