Here are a few hints which might help installing `tar' on some systems.
|
|
|
|
|
|
+* gzip and bzip2.
|
|
|
+
|
|
|
+GNU tar uses the gzip and bzip2 programs to read and write compressed
|
|
|
+archives. If you don't have these programs already, you need to
|
|
|
+install them. Their sources can be found at:
|
|
|
+
|
|
|
+ftp://ftp.gnu.org/gnu/gzip/
|
|
|
+http://sourceware.cygnus.com/bzip2/
|
|
|
+
|
|
|
+If you see the following symptoms:
|
|
|
+
|
|
|
+ $ tar -xzf file.tar.gz
|
|
|
+ gzip: stdin: decompression OK, trailing garbage ignored
|
|
|
+ tar: Child returned status 2
|
|
|
+
|
|
|
+then you have encountered a gzip incompatibility that should be fixed
|
|
|
+in gzip 1.3, which is not yet available as of this writing. You can
|
|
|
+work around the incompatibility by using a shell command like
|
|
|
+`gzip -d <file.tar.gz | tar -xzf -'.
|
|
|
+
|
|
|
+* Solaris issues.
|
|
|
+
|
|
|
+If you are compiling with GCC, you may need to upgrade GCC to 2.95.2
|
|
|
+or later before compiling GNU tar, as GNU tar exercises many features
|
|
|
+that can cause problems with older GCC versions, mostly having to do
|
|
|
+with mutations to Solaris system include files.
|
|
|
+
|
|
|
+Recent versions of Solaris tar sport a new -E option to generate
|
|
|
+extended headers in an undocumented format. GNU tar does not
|
|
|
+understand these headers.
