Hi, I hope this question isn't stupid. I really like tap and I just found this implementation, but I don't really need any of the other stuff in here. Would it make sense to move tap itself into a different repo?

Hi.

I am trying to compile your project, and get an error:
blib\headers/perl++/scalar.h:185: error: expected identifier before 'void'
blib\headers/perl++/scalar.h:185: error: expected '}' before 'void'
blib\headers/perl++/scalar.h:185: error: expected unqualified-id before ',' token
blib\headers/perl++/scalar.h:185: error: two or more data types in declaration of 'SCALAR'
blib\headers/perl++/scalar.h:185: error: expected initializer before '}' token

line 185 is: enum context {VOID, SCALAR, LIST};

I am using Strewberry Perl 5.12 on Windows with MingW.
I tried, but could not spot the problem. maybe my C++ is out of shape...

Thanks,
Shmuel.

is(0.0, 0.0, "0 is 0") ... fails?

but :

is(0, 0, "0 is 0") ... is OK?

int foo = typecast_to(scalar);
is(foo, 1, "foo == 1");

This fails at run time in the 40-typecasts.C test. The cast function returns zero. I confirmed it also fails for other built in types including double and float.

The template specialization included below fixes specifically the "int" failure. My template fu is too weak to dive into interpreter.h.

Hello there!
I'm running Linux Ubuntu (10.10) with Perl 5.10.1 and I downloaded the whole kaboodle, downloaded a couple of packages that the doc said I needed, compiled it (following the instructions to the letter) and when I try to compile a simple file I get heaps and heaps of error messages. Here's my file:
#include <perl++/perl++.h>
int main () {
wPerl perl;
perl.eval("print q(Hello, world!\n)");
return 0;
}
So I try to compile that with:
g++ -lperl++ perl-i.cpp
and also try
gcc -lperl++ perl-i.cpp
to no avail. My errors are contained in this pastebin: http://pastebin.com/m5Gtvuyk
I'm not quite sure what's happening wrong ;). I dunno if it's me or you, but yeah, this library looks awesome and I'd really like to get it working :)

Im getting following error compiler error in exporter.C, just few errors here
perl++/source/exporter.C:133:2: error: 'Argument_stack' does not name a type
perl++/source/exporter.C:133:2: error: 'PERL_MAGIC_uvar' was not declared in this scope

You forgot to modify is() to be like isnt()

Needed to bring in "catdir" for ./Build to even run.

We've tried to use the library with multiple constructors on the c++ end to no avail.

It seems like only the last one registered is taken into account.

Would it be possible for multiple function definitions to be supported? I guess it is just a matter of mapping.

Thanks.

The code in the libtap++.pod synopsis does not compile.

$ g++ foo.cpp
foo.cpp:1:21: fatal error: tap++.h: No such file or directory
compilation terminated.

The correct path is <tap++/tap++.h>

You can pull from my repo to get a fixed version.

The POD tests were skipped on my system. I was curious why, as I had Test::Pod installed. Turns out taint mod means $PERL5LIB gets ignored, and all my perl stuff lives in ~/perl5 thanks to local::lib.

Questionable if this is a bug or not, but here you go.

I created a new MSVC project added all your files.
After adding few undefs in internel.h
I am getting compilation errors related to perl::implementation::array::Temp
The issue is with compiler it mixes up typename with declaration

read_config returns an empty hash reference on my machine, as I have no modulebuildrc file. This leads to a fatal dereference of a null value. Suggest attached change.

  Failed test:  1
  Non-zero exit status: 1
Files=21, Tests=369,  1 wallclock secs ( 0.17 usr  0.09 sys +  0.18 cusr  0.17 csys =  0.61 CPU)
Result: FAIL

Looking at what specifically failed, I got a shared library load error.

$ t/40-typecasts.t 
t/40-typecasts.t: error while loading shared libraries: libperl++.so: cannot open shared object file: No such file or directory

When I do a
./Build install; ./Build clean; ./Build test

Then I get:

$ t/40-typecasts.t 
1..4
not ok 1 - foo == 1
# Failed test 'foo == 1'
#        Got: 0
#   Expected: 1
ok 2 - bar.value == 1
ok 3 - typecast_from(1) == 1
ok 4 - typecast_from(bar) == 1

Which is what is expected until issue #8 is resolved

Get loads of errors like these:
/usr/lib/gcc/x86_64-unknown-linux-gnu/4.6.0/../../../../include/c++/4.6.0/bits/random.h:198:17: error: macro "seed" passed 1 arguments, but takes just 0

There's some conflict between std::algorithm and perl.h, at least in recent g++.
Fix by adding an "undef seed".
