Hi, I also tried perl 5.6.1 with MULTIPLICITY turned on (instead of turning on both USETHREADS and USEITHREADS), and got the same compilation errors.

Thanks.

Subject:        swig 1.1.883 incompatible with certain configuration of perl 5.6.x




Hi,

Environment:
. Solaris 5.8
. swig 1.1.883
. gcc 2.95.2
. perl 5.6.0, default configuration, under /usr/local/bin/perl and /usr/local/lib/perl5/5.6.0/sun4-solaris
. perl 5.6.1, turn on USETHREAD and USEITHREAD, under /opt/usr/local/bin/perl and /opt/usr/local/lib/perl5/5.6.1/sun4-solaris-thread-multi

. I used the standard example.c and example.i.

While swig 1.1.883 can generate the _wrap.c file successfully under either perl, the gcc compilation with the default-configured perl (sun4-solaris) is ok but the 2nd perl (sun4-solaris-thread-multi) is not ok (conflicting types for boto_example in line 559 and line 431).  I have enclosed the typescript.

I can provide detailed perl configurations and even the compiled perl perl if needed.

swig is a great tool.  But we do need the advanced features (USETHREAD and USEITHREAD) of perl.  Is there any work around?

Thanks.
