I have my local OpenWRT SVN development trunk resides in /opt/tmp/openwrt-svn-trunk directory. I configured my local OpenWRT using scripts/env to build several different platform OpenWRT firmware without a problem. For my Seagate DockStar device, I included perl package. After my Seagate DockStar device boots on OpenWRT firmware, I did a perl -V and it returns the following:

It appears to look good at a glance. However, a closer look at the above output from a perl -V indicates all the paths point to /opt/tmp/openwrt-svn-trunk/staging_dir/target-arm_v5te_uClibc-0.9.31_eabi and not the /usr/lib/perl5/5.10 directory where the actual perl5 codes reside. If I execute the same perl compiled for my Seagate DockStar device (/opt/tmp/openwrt-svn-trunk/staging_dir/target-arm_v5te_uClibc-0.9.31_eabi/usr/bin/perl -V) on my OpenSuSE Linux desktop computer, it returns errors as shown below:

[mazilo@Mi:/opt/tmp/openwrt-svn-trunk 152%] ~ /opt/tmp/openwrt-svn-trunk/staging_dir/target-arm_v5te_uClibc-0.9.31_eabi/usr/bin/perl -V

BEGIN failed--compilation aborted.

Something doesn't sound right to me, but I just don't know how to fix this and hope OpenWRT developers will be able to fix this easily. Without this, I can't compile the mod_perl of FreeSWITCH package.

FYI, if I execute perl -V on my OpenSuSE Linux desktop computer, it returns the following with the correct path.

Hi guys,

I have a problem setting the correct perl env in my Backfire 10.03.1-rc4 box. I installed all perl and modules from package but I get this:

root@Keszi:/mnt/router/curl# perl -V
Can't locate Config.pm in @INC (@INC contains: /usr/lib/perl5/5.10 .).
BEGIN failed--compilation aborted.

Could you please give me somebody any advice what is missing?

Thanks

The discussion might have continued from here.
