So I have this problem: Mac::Carbon takes a long time to load.
$ time perl -Iblib/arch -Iblib/lib -MMac::Carbon -e1
real 0m2.923s
user 0m2.570s
sys 0m0.160s
Profiling the run showed that over 80% of that time is taken by dyld, so I
wondered if prebinding could solve the problem. However, perl uses .bundle
files for DynaLoader, and .bundle files cannot be prebound.
Drat.
But .dylib files can be prebound, and I was able to modify DynaLoader.xs to
load in either .bundle or .dylib files, and to compile my extensions as
.dylib files.
Woop.
But I am having problems with the prebinding. I first had to rebuild
libperl.dylib with prebinding, and that worked fine (just added -prebind).
Woop woop.
I added -prebind to my extension, and it complained that you can't use
-undefined suppress with -prebind. Remove -undefined suppress, and got
warnings about undefined symbols. Go figure.
So I added -L/path/to/perl -lperl, and did it again, and I got complaints
about conflicting symbols.
ld: warning prebinding disabled because of symbols overridden in
dependent dynamic shared libraries:
/usr/lib/libSystem.dylib(crypt.So) definition of _crypt
/usr/lib/libcrypto.0.9.dylib(fcrypt.o) definition of _crypt
Drat drat.
Anyway, I know there are perhaps better places to ask about dylib and
prebinding, but I just wonder if anyone else has run into these issues with
perl, before I move on.
