Subject: [PATCH] Adapt Configure to GCC version 10
|
|
|
|
I got a notice from Jeff Law <law@redhat.com>:
|
|
|
|
Your particular package fails its testsuite. This was ultimately
|
|
tracked down to a Configure problem. The perl configure script treated
|
|
gcc-10 as gcc-1 and turned on -fpcc-struct-return. This is an ABI
|
|
changing flag and caused Perl to not be able to interact properly with
|
|
the dbm libraries on the system leading to a segfault.
|
|
|
|
His proposed patch corrected only this one instance of the version
|
|
mismatch. Reading the Configure script revealed more issues. This
|
|
patch fixes all of them I found.
