Bug ID: 1078438
           Summary: Templated types are causing "Could not find a typemap
                    for C type"
           Product: Red Hat Enterprise Linux 7
           Version: 7.0
         Component: perl-ExtUtils-ParseXS
          Assignee: [e-mail]

+++ This bug was initially created as a clone of Bug #1032181 +++

Description of problem:
When using perl-ExtUtils-ParseXS to build XS stuff (I don't know the
terminology here, sorry), errors like this happens:
https://rt.cpan.org/Public/Bug/Display.html?id=86367

Version-Release number of selected component (if applicable):
perl-ExtUtils-ParseXS-3.18-291.fc20.noarch

How reproducible:
Happend when building slic3r-xs

Steps to Reproduce:
1. Get slic3r tarball from
https://github.com/alexrj/Slic3r/archive/1.0.0RC1.tar.gz
2. unpack && cd Slic3r-1.0.0RC1/xs/ # be usre to be in xs folder
3. perl Build.PL && ./Build

Actual results:
<snip>
Could not find a typemap for C type 'std::vector< double >'.
The following C types are mapped by the current typemap:
'AV *', <snip>, 'wchar_t *'
 in /usr/bin/perl -MExtUtils::XSpp::Cmd -e xspp -- -t
"/home/churchyard/Stažené/Slic3r-1.0.0RC1/xs/xsp/typemap.xspt" 
"/home/churchyard/Stažené/Slic3r-1.0.0RC1/xs/xsp/TriangleMesh.xsp", line 138

Expected results:
No errors, just warnings

Additional info:
This is fixed in upstream release 3.22 and also in development release 3.18_03.

Fix is in Bug #1032181.

See the error in this build.log:

--- Comment #2 from Petr Pisar  ---
ExtUtils::ParseXS::Utilities::tidy_type() does not parse and normalize some C++
type declarations properly:

# perl -MExtUtils::ParseXS::Utilities=tidy_type -e 'print
tidy_type(q{std::vector< unsigned int >}), qq{\n}'
std::vector< unsigned int >

While the output should be:

std::vector<unsigned int>

This is fixed by upstream perl commit:

commit ae7fdf584559a304eb5992a58cd58349cc7c58da

EU::ParseXS: Attempt to canonicalize C++ types in tidy_type

Includes moving tidy_type to ExtUtils::Typemaps where it seems to
    belong. It's a pretty poor canonicalizer, but better than nothing!

The key change is:

+  # for templated C++ types, do some bit of flawed canonicalization
+  # wrt. templates at least
+  if (/[<>]/) {
+    s/\s*([<>])\s*/$1/g;
+    s/>>/> >/g;
+  }

in tidy_type().
