Hello, I recently installed ActivePerl build 822 and discovered that my SWIG-based extensions no longer compile. I am using Visual Studio .NET 2005 Enterprise and SWIG 1.3.31.
apk_wrap_perl_d.cxx(1232): error C2159: more than one storage class specified apk_wrap_perl_d.cxx(1232): warning C4518: 'typedef ' : storage-class or type specifier(s) unexpected here; ignored apk_wrap_perl_d.cxx(1232): warning C4502: 'linkage specification' requires use of keyword 'extern' and must precede all other specifiers The error stems from this change in XSUB.h. The following line: # define XS(name) void name(pTHX_ CV* cv) Became: # ifdef __cplusplus # define XS(name) extern "C" void name(pTHX_ CV* cv) # else # define XS(name) void name(pTHX_ CV* cv) # endif It is the extern "C" that is causing Visual C++ to blow up, reverting back to the old definition of XS fixes the problem.
