Re: Help setting up appveyor for Windows continuous integration testing

[David Mertens]

Hello Rob,

Thanks for all of this work! I'll go through all of this at various points
throughout the week, so I may send a couple of follow-up emails later.

Thanks!
David

Hello everyone,

The specific tcc error (given at 
https://ci.appveyor.com/project/run4flat/c-blocks/build/1.0.17#L47) is:


 C:/STRAWB~1/perl/lib/CORE/perl.h:2708: error: ';' expected (got 
"perl_os_thread")


What does line 2708  of perl.h contain ?
I get a very similar type of error when building C-Blocks-0.03 on Windows 
(perl-5.16, mingw.org build of gcc-4.7.0):


Building C-Blocks
Creating lib/C/Blocks/PerlAPI.xs
In file included from perl_h_QSJqVkp1.c:15:
In file included from C:/Mingw/perl516/lib/CORE/perl.h:610:
C:/MinGW/include/sys/types.h:27: error: ';' expected (got "__time32_t")

where line 27 is:

typedef __int32 __time32_t;

My first thought was that perl might be doing something incompatible with 
the __int32 symbol, as there's no problem with a C program that #includes 
sys/types.h.
But #including sys/types.h into an Inline::C script is also fine, so I think 
it's unlikely that perl is the culprit


Moving on  I don't get that error when I switch to perl-522, which uses 
the gcc-4.9.2 compiler provided by mingw-w64 project (different vendor).

Indeed, this compiler doesn't typedef __int32 at all.

However, with this combo, the C-Blocks-0.03 build fails with:

Building C-Blocks

C:/_32/gcc-straw-492/i686-w64-mingw32/include/vadefs.h:35: error: #error 
VARARGS not implemented for this compiler

Unable to serialize the header file

The error implies that the symbol  __WIDL__ has not been defined.
It looks to me (not entirely certain) that __WIDL__ is normally *not* 
defined for me.



Does anybody know what's going on?


Not me.
Note that these errors are being obtained just running "cpan -i C::Blocks". 
Appveyor is not involved (unless, of course, it's being called in as part of 
the cpan build).


One other odd thing:
I had to set the CPATH environment variable to the location of winsock2.h - 
otherwise that header could not be located.
In both C and Inline::C scripts that header is in the default search path - 
and gets #included fine.


Here's the error:

Unable to serialize the header file
lib/C/Blocks/PerlAPI.xs.PL failed at

I just noticed that setting CPATH also removes the "WIN32_LEAN_AND_MEAN" 
redefinition warning.
Also, win32.h #includes windows.h - and I *think* (could check if it's 
important) that should be enough to get winsock2.h #included.

Something is not quite right.

Cheers,
Rob
