Comments on: gcc 4.7 in, gcc 4.1 out https://www.dragonflydigest.com/2012/10/02/gcc-4-7-in-gcc-4-1-out/ A running description of activity related to DragonFly BSD. Wed, 03 Oct 2012 12:35:40 +0000 hourly 1 https://wordpress.org/?v=7.0 By: Justin Sherrill https://www.dragonflydigest.com/2012/10/02/gcc-4-7-in-gcc-4-1-out/comment-page-1/#comment-45556 Wed, 03 Oct 2012 12:35:33 +0000 http://www.shiningsilence.com/dbsdlog/?p=10481#comment-45556 Not “misunderstand” so much as “never had it explained to me before”. Thank you for the description; I was inferring the usage from conversation rather than from having used it. Post corrected.

Both are environment variables. If the environment variable CCVER equals “gcc47” then “cc”, “gcc”, “c++”, “g++” etc all refer to /usr/libexec/gcc47/ versions rather than /usr/libexec/gcc44 versions. You can use this at will, e.g.

> env CCVER=gcc47 cc –version should return version information for gcc47.

The only script that uses WORLD_CCVER variable is the global makefile. If WORLD_CCVER is set to “gcc47” then that script makes sure CCVER is set everywhere during the build. It applies to both world and kernel.

To recap: Use CCVER for everything except world and kernel, use WORLD_CCVER for world and kernel.

My interpretation is that the best tool wins, but if all things are equal between two candidates, take the one with the BSD-like license. However, tools are rarely equal.

Justin: CCVER and WORLD_CCVER must be capitalized. You have listed them as lower case in the post.

From day 1, DragonFlyBSD has been more focused on conceiving and proving deep operating system innovations, rather than license purity. It is what it is, there are BSD’s for many tastes. Its the beauty of a completely free market.

Because DragonFly as a whole project tends to be focused on utility rather than license? Because that’s what someone was willing to put the effort into for upgrading?

Those answers are kind of flippant, though maybe not the last one. More seriously, if you can point at a documented restriction on what DragonFly users can do because of the different license on the compiler, I’d like to see it.
