 |
|
Hi, Considering | Code: | [b]gcc-config -l[/b]
[1] x86_64-pc-linux-gnu-4.8.3 *
[2] x86_64-pc-linux-gnu-4.9.2
equery u gcc-4.8.3 gcc
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for sys-devel/gcc-4.8.3:
U I
+ + cxx : Build support for C++ (bindings, extra libraries, code
generation, ...)
- - doc : Add extra documentation (API, Javadoc, etc). It is
recommended to enable per package instead of globally
+ + fortran : Add support for fortran
- - gcj : Enable building with gcj (The GNU Compiler for the
Javatm Programming Language)
- - go : Build the GCC Go language frontend.
+ + graphite : Add support for the framework for loop optimizations
based on a polyhedral intermediate representation
- - mudflap : Add support for mudflap, a pointer use checking library
+ + nls : Add Native Language Support (using gettext - GNU locale
utilities)
- - nopie : Disable PIE support (NOT FOR GENERAL USE)
- - nossp : Disable SSP support (NOT FOR GENERAL USE)
+ + nptl : Enable support for Native POSIX Threads Library, the new
threading module (requires linux-2.6 or better usually)
- - objc : Build support for the Objective C code language
- - objc++ : Build support for the Objective C++ language
- - objc-gc : Build support for the Objective C code language Garbage
Collector
+ + openmp : Build support for the OpenMP (support parallel
computing), requires >=sys-devel/gcc-4.2 built with
USE="openmp"
- - regression-test : Run the testsuite and install the results (requires
FEATURES=test)
+ + sanitize : Build support various sanitizer functions
(ASAN/TSAN/etc...)
- - vanilla : Do not add extra patches which change default behaviour;
DO NOT USE THIS ON A GLOBAL SCALE as the severity of the
meaning changes drastically

For the time beeing, it is planned to remove fortran USE flag at gcc slot level 
Any advice on the subject?

Chances are, your CPU overheated or something. See if your heatsink is clean of dust and your fan is working. You could also try reducing the number of threads compiling in make.

Hi,
Little investigation revealed cpufreqd parameters to be to tightly set since almost every poll generated freq scaling.
After recalibrating, things when smoother from a general perspective.
Nevertheless some problem remained for gcc-compiling (+fortran).but for 4.8.3/4.8.4 not 4.9.2 which is another story.
Thks 4 ur attention, interest & support. |
