Rem This batch file unpacks the GDB distribution while simultaneously
|
|
Rem renaming some of the files whose names are invalid on DOS or conflict
|
|
Rem with other file names after truncation to DOS 8+3 namespace.

|
|
Rem Invoke like this:
|
|
Rem
|
|
Rem djunpack gdb-XYZ.tar
|
|
Rem
|
|
Rem where XYZ is the version number. If the argument includes leading
|
|
Rem directories, it MUST use backslashes, not forward slashes.
|
|
Rem
|
|
Rem The following 2 lines need to be changed with each new GDB release, to
|
|
Rem be identical to the name of the top-level directory where the GDB
|
|
Rem distribution unpacks itself.
|
|
set GDBVER=gdb-6.8

|
if "%GDBVER%"=="gdb-6.8" GoTo EnvOk

|
Rem If their environment space is too small, re-exec with a larger one
|
|
command.com /e:4096 /c %0 %1

|
Rem The following uses a feature of COPY whereby it does not copy
|
|
Rem empty files. We need that because the previous line will create
|
|
Rem an empty fnchange.tmp even if the command failed for some reason.
|
|
copy fnchange.tmp junk.tmp > nul
|
|
if not exist junk.tmp GoTo NoDjTar
|
|
del junk.tmp
|
|
sed -e 's,@V@,%GDBVER%,g' < fnchange.tmp > fnchange.lst
|
|
Rem See the comment above about the reason for using COPY.
|
|
copy fnchange.lst junk.tmp > nul
|
|
if not exist junk.tmp GoTo NoSed
|
|
del junk.tmp
|
|
djtar -x -n fnchange.lst %1

:NoDjTar
|
|
echo FAIL: DJTAR is not available or no fnchange.lst file in %1.
|
|

|
