DB_File-1.858 does not build on Rocky Linux 8.8 (aarch64)

[rmarable]

DB_File-1.858 does not build on Rocky Linux 8.8 due to an error caused by an unknown architectural extension called ssbs when compiled with GCC-12.2.0 on an AWS c6g-class instance.

This doesn't seem to be an issue for x86_64.

Any insights you could offer would be appreciated.

Hey @rmarable

First time I've seen a bug report from an ARM build of Perl. Also, that error message is new to me.

When the Perl binary is built it remembers the gcc settings used so that it can reuse them when building a module, like DB_File, that is partially written in C. Below is the gcc command line used when you built DB_File

gcc -c  -I/usr/local/BerkeleyDB/include -D_REENTRANT -D_GNU_SOURCE -O2 -ftree-vectorize -mcpu=native -fno-math-errno -fPIC -fwrapv -fno-strict-aliasing -pipe -fstack-protector-strong -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_FORTIFY_SOURCE=2 -O2   -DVERSION=\"1.858\" -DXS_VERSION=\"1.858\" -fPIC "-I/build/rocky8_arm64/software/Perl/5.36.0-GCCcore-12.2.0/lib/perl5/5.36.0/aarch64-linux-thread-multi/CORE"  -D_NOT_CORE  -DmDB_Prefix_t=size_t -DmDB_Hash_t=u_int32_t   version.c

The option that jumps out is -mcpu=native.

You could try removing that option to see if it helps. To do that download the DB_File tar bundle

wget https://cpan.metacpan.org/authors/id/P/PM/PMQS/DB_File-1.858.tar.gz
tar xvf DB_File-1.858.tar.gz
cd DB_File-1.858
perl Makefile.PL

Now edit the generated Makefile and delete -mcpu=native. Then run make test .

Does that make any difference?

@rmarable any updates on this issue?
