i am trying to compile tangram on my pi1 running a net-ua version of raspbian ( aka minimal raspbian net install). And i end up with the following error.

Code: Select all

What compiler switches are you using ?

Compiler switches, not compiler version.

how do i find out, and what is that?
[edit]
if you mean flags then...
none just simple
make rpi

the code compiles well on complete version on raspbian just error on a net-ua version

You are trying to build on a minimal system so it is not surprising that things are missing !

My guess is that the files in /opt/vc/ and subdirectories that are needed to build code that uses the bcm_host APIs are missing.

Where do i get it from, github link???

The files are included in every full Raspbian build.

I can't help any more than that as I don't have a minimal install of Raspbian to investigate.

You probably want to copy hardfp/opt to /opt (I'm assuming the stuff listed in opt in there is compiled for softfp).
