Subject: external "C" lines
Hello It seems that some (recent?) versions of gcc doesn't support extern "C" static foo() and needs them to be declared properly as extern "C" { static foo() } Cheers ambs

I am still looking for further references on this. Anyway, example of a build failure: http://www.cpantesters.org/cpan/report/bc6d1ad0-3537-11e1-a48f-e7fb434ae6f1 The compiler is not that recent, so not sure about this (yet).

In fact, they are. 4.4.4 in some reports, 4.6.x on other. Cheers

Tried a 4.6.x compiler on linux, had no problem. Getting no clue on this one

Can't help you here. My g++ (4.6.1) build of blead-perl with the newest ParseXS already fails to build your Config::AutoConf dependency. You do the following: #ifdef __cplusplus extern "C" #endif #include <$header> ... Which I believe is wrong since it just makes the first bits in $header "extern "C"". t/03.checkheader.t .. # # # Ignore junk bellow. # In file included from /usr/include/stdio.h:75:0, from testUm2GYg.c:6: /usr/include/libio.h:346:1: error: invalid use of ‘extern’ in linkage specification etc. So that code needs to be: #ifdef __cplusplus extern "C" { #endif #include <$header> ... #ifdef __cplusplus } #endif in order for me to even begin debugging this. I have a hunch that you're seeing a similar extern "C" leakage problem. Cheers, Steffen

Correct. This one I can fix easily :) The curious thing is that in those reports they build Config::AutoConfig correctly. Portability is shit :( Can I request you keep this open for some more time? I'll be adding details as long as I find them Cheers ambs
