After upgrading GCC to version 12 on Linux (where strlcpy() does not exist)
|
|
tests fail like this if CFLAGS="-O1 -flto=auto":
|
|
|
|
make[1]: Entering directory '/home/test/fedora/perl-File-RsyncP/File-RsyncP-0.76/FileList'
|
|
"/usr/bin/perl" -MExtUtils::Command::MM -e 'cp_nonempty' -- FileList.bs ../blib/arch/auto/File/RsyncP/FileList/FileList.bs 644
|
|
PERL_DL_NONLAZY=1 "/usr/bin/perl" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, '../blib/lib', '../blib/arch')" t/*.t
|
|
t/exclude.t ... Can't load '/home/test/fedora/perl-File-RsyncP/File-RsyncP-0.76/FileList/../blib/arch/auto/File/RsyncP/FileList/FileList.so' for module File::RsyncP::FileList: /home/test/fedora/perl-File-RsyncP/File-RsyncP-0.76/FileList/../blib/arch/auto/File/RsyncP/FileList/FileList.so: undefined symbol: strlcpy at /usr/lib64/perl5/DynaLoader.pm line 193.

The new compiler optimizes out a check for strlcpy() perform by
|
|
FileList/configure script. This patch changes the check to actually depend on
|
|
strlcpy() function address. That should prevent a compiler from optimizing it
|
|
out.
