Subject:

long double troubles with 5.22.0

While trying to build+install Win32-API-0.82 on 64bit 5.22.0 perl (built with gcc-4.9.2) I have experienced the failure in t/00_API.t

#   Failed test 'function call with double arguments'
#   at t/00_API.t line 193.

NOTE: it is the only failing test

I do not have more details at the moment.

Are you using a public Strawberry Perl or this is just a private GCC build with long double NVs as an experiment?

I am trying to build 64bit portable strawberry perl 5.22.0 with long double NV (via dmake USE_LONG_DOUBLE=define).

I am still tuning the build. Once I am finished I will make it available for experimenting on http://strawberryperl.com/beta.html + post a notice here.

Hi, here is an update with Win32-API-0.84 on perl 5.022003(RC4) built for MSWin32-x64-multi-thread-ld

ad 00_API.t
- ok($function->Call(2.5, 3.2) == 5.7, 'function call with double arguments');
+ ok(abs($function->Call(2.5, 3.2) - 5.7) < 0.1, 'function call with double arguments');
