Compiling Perl5.8.8 on ARMv7eb

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

I have cross compiled tool chain for armv7eb. Now I have copied the tools to my target machine and tried to build perl on target. In this process of building perl, there is a binary called 'miniperl' which gets crashed saying "ILLEGAL INSTRUCTION".

Can someone help me point out what I should be doing ? PERL VERSION: 5.8.8 GCC: 4.1.3 PLease find the crash log below. anybody has any suggestions.

sh  cflags "optimize='-O'" opmini.o` -DPIC -fPIC -DPERL_EXTERNAL_GLOB

Cross-compiling Perl has improved vastly in the more recent versions. Have you had success cross-compiling Perl 5.22? Only after this (and finding out all the parameters), I would look at compiling something ancient as 5.8.8. You did not say for what OS you compiled. If it is for Android, I happen to have an ARMv7 Perl there, compiled for Android with the CCTools installed.	[reply]

I am using NetBSD5.1. we working our legacy SW package, which runs on PPC and MIPS platform. We are trying to port complete SW package on newer ARM7 targets.	[reply]

Even though it will be lots slower, I would first try to do a native compilation of Perl 5.8.8 on the target machine. Compiling and testing Perl 5.22.0 on an ARMv7 (MediaTek) takes around 40 minutes and that would eliminate the "usual" architecture mix problems you get by trying out cross-compilation.	[reply]
