Compiling perl on 64 bit system

rlb3 has asked for the wisdom of the Perl Monks concerning the following question:

I'm having lots of trouble compiling perl 5.10.0 on CentOS 5.1 x86_64. This is the configure line I'm using:

./Configure -des -Dprefix=/usr -Acflags='-fPID -DPIC -m64' -Aldflags='
+-L/usr/lib64 -L/lib64 -lm'
[download]

It compiles and make test works but if I use CPAN to install Bundle::CPAN I start getting internal perl errors like:

Attempt to free unreferenced scalar: SV 0x2v363923
[download]

Does anyone know the magic formula to compile perl on 64 bit systems? Oh, and the same thing happens if I compile perl 5.8.8 with the same config line.

Are you sure about the -m64 option? My gcc doesn't mention it as an x86 flag. What happens if you accept the defaults for everything? "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply]

If I leave everything off miniperl errors out and make fails. rlb3	[reply] [d/l]

Last time I compiled Perl for a 64 bit machine I had real problems that arose from the fact I initially tried to build a 64bit version with a 32 bit version of gcc. Are you sure that the files created by your gcc are 64bit? I tested by creating hello.c, compiling it and runing the `file` command on the result. I found that having a 64 bit version of gcc which created 64bit executables by default made all the issues go away.	[reply]

Sorry I was out on vacation last week... This is what I get after running file on a test binary: `test: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU +/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2. +6.9, not stripped` [download] rlb3	[reply] [d/l]

Why did you not leave the basics to Configure? `./Configure -Duse64bitall -Dprefix=/usr -des` and report back what fails. The next step - if it still fails - is to check for a hint file, and put the missing hints in hints/centos.sh (or whatever it is trying to use). Enjoy, Have FUN! H.Merijn	[reply] [d/l]

I think I found a configure line that is working for me. `./Configure -des -Dprefix=/usr -Acflags='-fPID -DPIC -m64' -Aldflags=' +-L/usr/lib64 -L/lib64 -lresolv -lnsl -ldl -lm -lcrypt -lutil -lc'` [download] Thank you to everyone who replied rlb3	[reply] [d/l]
