If you're going to manually patch a distribution, you forego most of the automation that CPAN provides you and have to do the steps manually:

1. Download and unpack the distribution. If in a hurry, you can let CPAN do that for you:

   cpanm --look Devel::CallParser
   [download]

   or

   cpan
   CPAN> look Devel::CallParser
   </li>
   <li>Patch the distribution:
   <c>
   patch < rt110623.patch
   [download]

2. Test the distribution:

   perl Makefile.PL
   make
   make test
   [download]

3. Install the distribution:

   make install
   [download]

4. Keep a backup of the current directory, for the next installation

Update: Corrected invocations of tools, as spotted by ibm1620

Hi,

Thanks :)

I just tried the method you said, but it seems to "hang" on the 2nd step:

root@mail:~# cd Devel-CallParser-0.002/
root@mail:~/Devel-CallParser-0.002# patch ../fix.patch
^X^C

Any ideas?

Oh, and I also agree about not being able to get the best out of the CPAN system - but unfortunately until they fix the bug in the official release, I can't use it :(

Thanks!

Andy

I don't know what format the patch file is in and how your patch command expects its input.

The patch command I know expects its input on stdin, which is why I showed the suspected command line as

patch < whatever.patch
[download]

Maybe your patch command is different.

Should that be cpanm --look Devel::CallParser ?

Update: This is perhaps a long winded approach, but I think it helps to understand the process in full.

Download the module, extract the archive, then:

wget https://rt.cpan.org/Ticket/Attachment/1576496/841876/0001-Fix-a-p
+ad-problem-with-Perl-5.21.4-on-threaded-build.patch
marto@shemp ~/Devel-CallParser-0.002 $ patch -p1 < 0001-Fix-a-pad-prob
+lem-with-Perl-5.21.4-on-threaded-build.patch
patching file lib/Devel/CallParser.xs
patching file t/pad2.t
[download]

Notice that the patch has created the new file you're looking for (you can see everything the patch does by reading it and following the logic). Then:

marto@shemp ~/Devel-CallParser-0.002 $ cpanm .
--> Working on .
Configuring Devel-CallParser-0.002 ... OK
Building and testing Devel-CallParser-0.002 ... OK
Successfully installed Devel-CallParser-0.002
1 distribution installed
[download]

Ah you star - that did it. I missed the -p1 part from the query. I still get this though:

patch -p1 < 0001-Fix-a-pad-problem-with-Perl-5.21.4-on-threaded-build.
+patch
can't find file to patch at input line 19
Perhaps you used the wrong -p or --strip option?

UPDATE: Never mind, me being dumb! I was in the wrong directory, so it couldn't find the files ;)

Can you show me the path you're doing this from, and an ls within the current working directory?

diff --git a/t/pad2.t b/t/pad2.t
new file mode 100644
index 0000000..92c6dab
--- /dev/null
+++ b/t/pad2.t
[download]

The /dev/null means the file is new, it shouldn't have existed before the patch was applied.
