[Buildroot] Issue with using PPL package for gcc 4.4.4

[Ramesh GK]

Hi Peter et al,

Thought of updating this thread. I was able to resolve the issue. The issue was in fact reflecting on the configure log and I missed it as I was trying to add the same option in PPL by mistake.

Following are the changes that had to be done for gcc 4.4 -

GMP:
HOST_GMP_CONF_OPTS += --enable-cxx

PPL:
For PPL, I had to merge some changes to patches for fpermissive and ptrdiff_t issue due to GCC being 4.9.x along with local gmp resolution.

I still have to verify the authenticity of how things are working as I am on a buildroot-2018.02.12 version but at this point hoping that this should help me to get the path I was looking for.

Thanks
Ramesh GK

Hi Peter,

I tried that approach as you have suggested but it did not work. The problem looks to be something with how the linking is happening i believe but not sure.

On the same host, I did try with crosstool-ng to verify and it worked successfully but is failing within buildroot.

I am happy to explore further if there are more ideas on how to resolve this issue.

Thanks
Ramesh GK

I am facing this weird issue despite trying different options and looking for if anyone could help or have got success with setting up the ppl package within buildroot.

Maybe missing:

        HOST_PPL_DEPENDENCIES += host-gmp
