On this basis I'm reporting the bug against perl. Attempting to build a swig-generated perl extension, like the attached example, produces many errors like: /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/CORE/perlvars.h:35: error: invalid use of ‘register’ in linkage specification A workaround is to "#define register" (i.e. null out the register keywork completely) Version-Release number of selected component (if applicable): perl-5.8.8-6 gcc-4.1.1-3 swig-1.3.29-0.1 How reproducible: 100% problem verified on x86_64 and i386 platforms Steps to Reproduce: 1. zcat bug.tgz | tar xf - 2. cd bug 3. make Actual results: swig -c++ -perl5 -o example_wrap.cpp example.i /usr/bin/g++ -I`perl -e 'use Config; print $Config{archlib};'`/CORE -fPIC -DPIC -c -o example_wrap.o example_wrap.cpp /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/CORE/thrdvar.h:34: error: invalid use of ‘register’ in linkage specification /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/CORE/thrdvar.h:38: error: invalid use of ‘register’ in linkage specification /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/CORE/thrdvar.h:40: error: invalid use of ‘register’ in linkage specification ... /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/CORE/perlvars.h:66: error: invalid use of ‘register’ in linkage specification /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/CORE/perlvars.h:69: error: invalid use of ‘register’ in linkage specification /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/CORE/perlvars.h:73: error: invalid use of ‘register’ in linkage specification example_wrap.cpp:1421: error: invalid use of ‘register’ in linkage specification example_wrap.cpp:1871: error: invalid use of ‘register’ in linkage specification make: *** [example_wrap.o] Error 1 Expected results: (uncomment the hack that adds "#define register" in Makefile) $ make clean rm -f *.o example_wrap.cpp example.pm libexample* $ make swig -c++ -perl5 -o example_wrap.cpp example.i (echo "#define register"; cat example_wrap.cpp) >example_wrap.cpp.tmp mv -f example_wrap.cpp.tmp example_wrap.cpp /usr/bin/g++ -I`perl -e 'use Config; print $Config{archlib};'`/CORE -fPIC -DPIC -c -o example_wrap.o example_wrap.cpp /usr/bin/g++ -I`perl -e 'use Config; print $Config{archlib};'`/CORE -fPIC -DPIC -c -o example.o example.cpp g++ -shared example_wrap.o example.o -o libexample.so $ ./example.pl 24 Additional info: ------- Additional Comments From ellson@xxxxxxxxxxxxxxxx 2006-06-15 09:19 EST ------- Created an attachment (id=130972) --> (https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=130972&action=view) small test case -- Configure bugmail: https://bugzilla.redhat.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
