I should replace DEVTOOLSETSIX='y' with DEVTOOLSETSEVEN='y' right?

rdan · Nov 6, 2017

From this:

Code:

CLANG='n'
DEVTOOLSETSIX='y'
NGINX_DEVTOOLSETGCC='y'
GENERAL_DEVTOOLSETGCC='y'
CRYPTO_DEVTOOLSETGCC='y'

To this?

Code:

CLANG='n'
DEVTOOLSETSEVEN='y'
NGINX_DEVTOOLSETGCC='y'
GENERAL_DEVTOOLSETGCC='y'
CRYPTO_DEVTOOLSETGCC='y'

Sunka · Nov 6, 2017

yep

Code (Text):

NGINX_DEVTOOLSETGCC='y' # umjesto clang ide gcc kompilacija kod nginx
DEVTOOLSETSEVEN='y' # ide 7.x verzija gcc kompilacije umjesto defaultne 5.x ili 6.x
CLANG='n' # potrebno za gcc kompilaciju nginx
CRYPTO_DEVTOOLSETGCC='y' # newer Intel GCC

yup looks good

yup

FYI, CRYPTO_DEVTOOLSETGCC='y' is still some work in progress that you might not want to enable especially on cloud vps like linode where migrating between host vps nodes changes the cpu model/family.

also added GCC 7.2.1 support to CentOS 6.x now as well Beta Branch - add devtoolset-7 GCC 7.2.1 support to CentOS 6.x 123.09beta01

Thanks!

Why is it this isn't default right now?
devtoolset-7 for GCC 7.2.1 or Clang 4.0.1.

Just curious .

eva2000 · Nov 22, 2017

Stability first while testing as there's no idea if any older or specific cpu modules might not like the newer compilers for something and well it adds to initial install times too quite a bit compared to default system compiler.

rdan · Nov 22, 2017

Both Clang and GCC has Intel CPU optimization?

eva2000 · Nov 22, 2017

Yes. Newer versions like GCC 7 and eventually GCC 8 and Clang 5 and 6 will support newer cpus like Intel Skylake and AMD Ryzen/EPYC optimisations eventually too https://www.phoronix.com/scan.php?page=article&item=epyc-compilers-nov&num=1
