[lttng-dev] [EXTERNAL] Re: lttng 2.12 install

[Weber, John]

Ok, it I get what you're saying then I am modifying make on the command line while running make? Still the same problem. I don't think it is using the gcc I am specifying as it continues to look in: /usr/src/kernels/3.10.0-1127.19.1.el7.x86_64/
And I suspect it is still seeing the OS version of gcc (4.8.5) instead of the 6.3.1 provided by devtoolset-6.
Do you have some pixy dust??

Hi John,

AFAIK, you should be able to do so using something similar to the following:

  make CC="your_compiler" HOSTCC="your_compiler" ...

Cheers
