[Buildroot] Issue with using PPL package for gcc 4.4.4

[Buildroot] Issue with using PPL package for gcc 4.4.4

[Ramesh GK]

Hi,

I have a need to use gcc 4.4.4 version for buildroot and trying to get the ppl package embedded within buildroot itself rather than using an external toolchain. 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.

I am also attaching the full log from buildroot specific to the package.

Host Machine: gcc 4.9.2, gmp 6, mpfr 3.1.2, mpc 1.0.2, cloog 0.18.2, isl 0.12.2

Buildroot Specification for build: gcc 4.4.4, gmp 4.3.2, mpfr 2.4.2, mpc 0.8.2, cloog-ppl 0.15.11, ppl 0.10.2

Error:
checking for the GMP library version 4.1.3 or above... no
configure: error: Cannot find GMP version 4.1.3 or higher.
GMP is the GNU Multi-Precision library:
see http://www.swox.com/gmp/ for more information.
When compiling the GMP library, do not forget to enable the C++ interface:
add --enable-cxx to the configuration options.
package/pkg-generic.mk:221: recipe for target '/home/mht/disk/mht/obuilds/template-4.4.4-2.6/build/host-ppl-0.10.2/.stamp_configured' failed
make[1]: *** [/home/mht/disk/mht/obuilds/template-4.4.4-2.6/build/host-ppl-0.10.2/.stamp_configured] Error 1
Makefile:23: recipe for target '_all' failed
make: *** [_all] Error 2

Thanks

Maybe missing:

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

[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

Looking at your build log I would guess you are missing C++ support 
(BR2_TOOLCHAIN_BUILDROOT_CXX) in your toolchain.

Kind regards,
Andreas
