Upgraded to Fedora 41, new compiler that comes with it seems to have -Wreturn-mismatch enabled.
When trying to install DBD::Oracle with cpan, I get this error: dbdcnx.c:90:25: error: ‘return’ with no value, in function returning non-void [-Wreturn-mismatch] 90 | if(llist_empty(el)) return;\ Looking at dbdcnx, the llist_drop(ael) macro does contain the return line above. The macro is used in functions release_env, which returns a void find_env, which returns a env_box_t* release_pool, which returns a void and the call within find_env needs a "return NULL;" instead. I was able to make it compile with two (silly) methods - duplicated the macro with return NULL instead of return called it from find_env - added argument to the macro llist_drop(ael, ret) called it as llist_drop(&box->base.lock, return); or llist_drop(&box->base.lock, return NULL); where appropriate. Both approaches compile, have the first one in place, will try the second later. -- Henrique ----------------------------------------------------------------- I also get a deprecation warning as below, didn't look at it Oracle.xs: In function ‘XS_DBD__Oracle__st_ora_fetch’: Oracle.xs:233:9: warning: ‘Perl_dowantarray’ is deprecated [-Wdeprecated-declarations] 233 | if (GIMME == G_SCALAR) { /* XXX Oraperl */ | ^~ In file included from /usr/lib64/perl5/CORE/perl.h:6186, from /usr/lib64/perl5/vendor_perl/auto/DBI/DBIXS.h:23, from Oracle.h:50, from Oracle.xs:1: /usr/lib64/perl5/CORE/proto.h:1031:1: note: declared here 1031 | Perl_dowantarray(pTHX)
