I'm trying to use pkgsrc on ubuntu 16.04 LTS.
Installation was vary easy.
$ cvs -q -z3 -d [email protected]:/cvsroot checkout -P pkgsrc
$ ./bootstrap --unprivileged
Then I installed unzip package from source. It looked success too.
$ cd pkgsrc/archivers/unzip/
$ bmake
$ bmake install
$ which unzip
/home/xxxx/pkg/bin/unzip
However it didn't work when it was executed.
$ cd ~
$ ls
aaa.zip
$unzip aaa.zip

Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir]
Default action is to extract files in list, except those in xlist, to exdir;
file[.zip] may be a wildcard. -Z => ZipInfo mode ("unzip -Z" for usage).
-p extract files to pipe, no messages -l list files (short format)
-f freshen existing files, create none -t test compressed archive data
-u update files, create if necessary -z display archive comment only
-v list verbosely/show version info -T timestamp archive to latest
-x exclude files that follow (in xlist) -d extract files into exdir
modifiers:
-n never overwrite existing files -q quiet mode (-qq => quieter)
-o overwrite files WITHOUT prompting -a auto-convert any text files
-j junk paths (do not make directories) -aa treat ALL files as text
-C match filenames case-insensitively -L make (some) names lowercase
-X restore UID/GID info -V retain VMS version numbers
-K keep setuid/setgid/tacky permissions -M pipe through "more" pager
See "unzip -hh" or unzip.txt for more help. Examples:
unzip data1 -x joe => extract all files except joe from zipfile data1.zip
unzip -p foo | more => send contents of foo.zip via pipe into program more
unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer
$ echo $?
10
$ ls
aaa.zip
The error code was 10, which means invalid options were specified on the command line. Why? I didn't think I added any options. I was confused.
So I deleted pkgsrc's unzip to compare ubuntu's unzip and it worked.
$ pkg_delete unzip
$ which unzip
/usr/bin/unzip
$ /usr/bin/unzip aaa.zip
Archive: aaa.zip
extracting: aaa.txt
$ls
aaa.txt aaa.zip
pkgsrc's unzip is broken? or did I overlook some settings I had to do?
update(2017-2-19 14:30):
I'm reading the pkgsrc's source code(pkgsrc/archivers/unzip). it is generated after bmake.
So far, I partially changed unzip.c as following:
-- unzip.c --
int MAIN(argc, argv)
int argc;
char *argv[];
{
int r;
CONSTRUCTGLOBALS();
/* for debug ----> */
int hoge;
printf("argc %d\n", argc);
for(hoge = 0; hoge < argc; hoge++){
printf("argv[%d] %s\n", hoge, argv[hoge]);
}
/* for debug <---- */
r = unzip(__G__ argc, argv);
DESTROYGLOBALS();
RETURN(r);
}
....
....
int unzip(__G__ argc, argv)
__GDEF
int argc;
char *argv[];
{
....
....
#endif /* !NO_ZIPINFO */
/* for debug ----> */
printf("argc: %d\n", argc);
printf("&argc: %d\n", &argc);
int hoge = 0;
for(hoge = 0; hoge < argc; hoge++){
printf("argv[%d]: %s\n", hoge, argv[hoge]);
}
/* for debug <---- */
error = uz_opts(__G__ &argc, &argv);
}
int uz_opts(__G__ pargc, pargv)
__GDEF
int *pargc;
char ***pargv;
{
...
...
while (++argv, (--argc > 0 && *argv != NULL && **argv == '-')) {
s = *argv + 1;
while ((c = *s++) != 0) { /* "!= 0": prevent Turbo C warning */
/* for debug ----> */
printf("c: %c\n",c);
/* for debug <---- */
#ifdef CMS_MVS
switch (tolower(c))
#else
switch (c)
#endif
{
case ('-'):
++negative;
break;
...
...
default:
printf("SET ERROR\n"); /* for debug */
error = TRUE;
break;
}
...
...
#endif /* !SFX */
return USAGE(error);
...
...
}
#else /* !SFX */
# ifdef VMS
# define QUOT '\"'
# define QUOTS "\""
# else
# define QUOT ' '
# define QUOTS ""
# endif
int usage(__G__ error) /* return PK-type error code */
__GDEF
int error;
{
if (error){
/* for debug ----> */
puts("PK_PARAM: L");
/* for debug <---- */
return PK_PARAM;
} else {
...
}
}
With this change I understood argc and argv is changed before uz_opts() in unzip(). And the option -O CP932, which is internally added, doesn't exist in the swich statement in uz_opts(), that cause exit code 10.
$ unzip aaa.zip
argc 2
argv[0] unzip
argv[1] /home/xxxx/aaa.zip
argc: 4
&argc: -740106452
argv[0]: unzip
argv[1]: -O
argv[2]: CP932
argv[3]: /home/xxxx/aaa.zip
c: O

Then I checked environment variables, it is there...
$env

UNZIP=-O CP932
What is this? I couldn't confirm it in my .profile and .bashrc.
