T1024: How to change perl version in SDK2.0

[gouravjain]

Hi,

I have installed linux SDK 2.0 and generated toolchain as well. By default perl5.22 is being generated.

Can some one pls let me know how/where to make changes to get perl5.20 ??

Thanks in advance ...

Hi Vinod,

Thanks for the reply... but can you pls let me know with respect to NXP SDK2.0.

[yipingwang]

Please remove perl 5.22 recipes in sources/poky/meta/recipes-devtools/perl/, please use perl 5.20 recipes downloaded from perl\recipes-devtools\meta - poky - Poky Build Tool and Metadata to replace them.

$bitbake perl -c cleansstate

$bitbake perl

Please remove original perl 5.22 recipes, then run command "bitbake perl -c cleansstate" to clean the build cache.

[gouravjain]

Hi Yiping,

Even after removing perl 5.22 files, doing bitbake -c cleansstate, bitbake perl. It's not generating any files or dir related to 5.20.

I suspect some where its define version 5.22 and its taking from that. I'm not able to grep in which file i need to change this version number. If you have any idea about this pls let me know. 

[yipingwang]

Hello gourav jain,

Please add the following line in build_t1024rdb/conf/local.conf.

PREFERRED_VERSION_perl = "5.20"

Thanks,
Yiping

Hello Yiping,

After doing entry in local.conf and executing "bitbake perl -c cleansstate", i'm getting following log,

[hap@v-psg-mng build_t1024rdb]$ bitbake perl -c cleansstate

[yipingwang]

Please execute "bitbake perl -c cleansstate" first, then add PREFERRED_VERSION_perl = "5.20" in build_t1024rdb/conf/local.conf.

 libxml-parser-perl_2.44.bb
 liburi-perl_1.60.bb

Is there any more places from where i need to remove ??
