https://bugzilla.redhat.com/show_bug.cgi?id=2261448 --- Comment #8 from Petr Pisar <ppisar@xxxxxxxxxx> --- First error reported in the build.log is: In file included from Curses.c:434: CursesWide.c: In function ‘c_wstr2sv’: CursesWide.c:84:15: error: assignment to ‘wint_t *’ {aka ‘unsigned int *’} from incompatible pointer type ‘wchar_t *’ {aka ‘long int *’} [-Wincompatible-pointer-types] 84 | for (ws_p = ws; *ws_p; ws_p++) { | ^ The variables are declared like this: static void c_wstr2sv(SV * const sv, wchar_t * const ws) { /*---------------------------------------------------------------------------- Set SV to a Perl string holding a given wide string -----------------------------------------------------------------------------*/ wint_t *ws_p; int need_utf8 = 0; size_t ws_len = wcslen(ws); and used like this (the line from the error message): for (ws_p = ws; *ws_p; ws_p++) { C17 standard in 7.29.1 section defines that wint_t is an integer which can hold any value of the extended character set (i.e. wchar_t) and at least one value which is not representable in the extended character set (i.e. WEOF). That means that size of wint_t cannot be less than size of wchar_t. Here on i686 "unsigned int" unsigned 32-bit and "long int" is signed 32-bit. While the conversion of the extended character value could be preserved (e.g. the extended charcter set ranges from 0 to 2^21), reinterpreting a wchar_t by a dereferencing a pointer to a wint_t could mangle the sign because the compiler thinks that the type have a different rank. Either it's a bug in GCC, or something incorrectly redigined the types, or it works as intended and one only need to explicitly cast "ws_p = (wint_t*)ws". I would the have dig deeper. -- You are receiving this mail because: You are on the CC list for the bug. https://bugzilla.redhat.com/show_bug.cgi?id=2261448 Report this comment as SPAM: https://bugzilla.redhat.com/enter_bug.cgi?product=Bugzilla&format=report-spam&short_desc=Report%20of%20Bug%202261448%23c8 -- _______________________________________________ perl-devel mailing list -- perl-devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to perl-devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/perl-devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
