/usr/lib/perl5/5.36/core_perl/CORE/libperl.a is a remnant from Chapter 7

[Xi Ruoyao]

In Chapter 7 we build Perl without -Duseshrplib. This installs a /usr/lib/perl5/5.36/core_perl/CORE/libperl.a file. But in Chapter 8 we build Perl with this option, so /usr/lib/perl5/5.36/core_perl/CORE/libperl.a is not overwritten, but /usr/lib/perl5/5.36/core_perl/CORE/libperl.so is installed.

Ideally we should add this option for Chapter 7 Perl too. If it does not work, we can remove libperl.a manually after Chapter 8 Perl is installed.

Are you sure libperl.a is not overwritten? On my system the timestamps are the same:

[ /mnt/lfs/usr/lib/perl5/5.36/core_perl/CORE ]$ ll lib*
-r--r--r-- 1 root root 5172514 Mar 14 20:44 libperl.a
-r-xr-xr-x 1 root root 3832000 Mar 14 20:44 libperl.so

Those timestamps correspond to installing perl in Chapter 8.

-r-xr-xr-x 1 root root 3832000 Mar 14 20:44 libperl.so

Those timestamps correspond to installing perl in Chapter 8.

But I have different results:

xry111@enterprise:~$ ls /mnt/build_dir/usr/lib/perl5/5.36/core_perl/CORE/libperl* -l
-r--r--r-- 1 root root 5267178 Mar 31 15:04 /mnt/build_dir/usr/lib/perl5/5.36/core_perl/CORE/libperl.a
-r-xr-xr-x 1 root root 4019656 Mar 31 16:09 /mnt/build_dir/usr/lib/perl5/5.36/core_perl/CORE/libperl.so

I also ran a DESTDIR install for Perl and there is no libperl.a in the DESTDIR. Maybe you got the same timestamp because of the stripping?

[Bruce Dubbs]

I was building with jhalfs. libperl.so is stripped, and the stripping indeed occurred at 20:44. It is interesting that the file command on the .a file only says "current ar archive".

Perhaps the best place to remove this file is Section 8.80 Cleaning Up.

We can try adding -Duseshrplib for Chapter 7 Perl first and let Chapter 8 to overwrite it (anyway the .so file seems smaller :). If it causes a FTBFS we can remove the file in Cleaning Up.

[Bruce Dubbs]

Seems like a good plan to me.

[Bruce Dubbs]

Adding -Duseshrplib to Chapter 7 Perl results in not producing libperl.a at all. That is really what we want.
