[Buildroot] Fwd: Fwd: how to assign cpp and c++ in buildroot?

[cem akpolat]

Hi Thomas,

I noticed the same failure:  you do not
have g++ on your machine.

Then I checked whether there is any link to g++, actually there is any g++
command, I assigned through the command sudo ln -s /usr/bin/g++-4.8 g++,
then recompile it again.
The compilation is now finished without errors. If I see this issue next
time, the only thing that I will do is to look at package/Makefile.in. I
assume that the whole configuration, if any of them aren't overwritten in a
package, is in the previous mentioned file. If I see the same error, first
of all I should check the commands that you provided me.

I cannot notice every detail sometimes, buildroot is quite new to me :).

Thank you so much,



Cem Akpolat
