Hi,

this is my first post ;-)

I'm a reader for nearly 20 years now, perhaps i can help today ;-)

Anyhow, the problem originates from the fact, that BigSur provides a native

XML Library and therefore the cc compiler will always favor the local libxml which differs from the version homebrew is providing.

homebrew version: '20904'

Big sur version: '20910'

How you can get it working: (Assuming you have perl-5.3.32 homebrew package installed)

1.) install the gcc homebrew package !

2.) Extract the source

3.) perl Makefile.PL

4.) Edit the Makefile

Change these lines:

Change the CC binary

 CC = gcc

Change the LD binary

 LD = gcc

Change the LDDFLAGS to:

LDDLFLAGS = -L/usr/local/opt/libxml2/lib -L/usr/local/lib/perl5/5.32.0
+/darwin-thread-multi-2level/CORE -mmacosx-version-min=10.15 -bundle -
+fstack-protector-
strong -lxml2 -lperl
[download]

Change the LDFLAGS to

LDFLAGS = -L/usr/local/opt/libxml2/lib -L/usr/local/lib/perl5/5.32.0/darwin-thread-multi-2level/CORE -mmacosx-version-min=10.15 -fstack-protector-strong -lxml2 -lperl

Change the INC Path to

INC = -I/usr/local/opt/libxml2/include

Change the PASSTHROUGH INC

PASTHRU_INC='-I/usr/local/opt/libxml2/include $(PASTHRU_INC)'

Then build:

make

Check using otool:

 
$otool  -L blib/arch/auto/XML/LibXML/LibXML.bundle
blib/arch/auto/XML/LibXML/LibXML.bundle:
    /usr/local/opt/libxml2/lib/libxml2.2.dylib (compatibility version 
+12.0.0, current version 12.10.0)
    /usr/local/opt/perl/lib/perl5/5.32.0/darwin-thread-multi-2level/CO
+RE/libperl.dylib (compatibility version 5.32.0, current version 5.32.
+0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current v
+ersion 1292.60.1)
    /usr/local/lib/gcc/10/libgcc_s.1.dylib (compatibility version 1.0.
+0, current version 1.0.0)
[download]

make test
[download]

(3 tests will fail because the tests favor the native libs, so don't mind

 make install

Best regards

Franz
