Try "qlist clang" so see what is installed, "qlist clang | grep bin/"

qlist is part of portage-utils, which you probably already have.




Done as requested. There are 41 files found with clang in their name

I'm no whiz bang sys-admin but that doesn't seem right to me. There is

Try those and see if they respond correctly.
If yes, add that dir to your PATH.

They work as expected and I can add the dir to the path with no
problems, I'm more concerned about why I have add the path - is the
ebuild screwed up in some way?

What is the portage/ebuild doco like? Is it well documented or are
there gaping holes that lead to frustration - my level of understanding
of coding is 25 years of C/C++ coding on CAD systems & engineering
applications and even though I run a Gentoo box as my default machine,
I've never had the need to get into bash scripting - but might.

Try running `env-update && source /etc/profile'. Your path should be
extended by /etc/profile.env which is generated from /etc/env.d/10llvm-9995.



SUCCESS!!

Thanks

I seem to recall clang clashing recently with some package, which required the 
clang USE flag to be unset - was it llvm?  I suspect as a result clang is no 
longer installed on my laptop.

[gentoo-user] Clang has gone walkabout

[Andrew Lowe]

Hi all,
	Do we have any clang users out there? I've had clang installed on my 
machine for ages and a simple "clang test.c" will result in an 
executable. I can even nearly build my whole machine using clang, so its 
up and running. I've now just updated clang, from a working 3.9.1 to a 
4.0.0-r1 and clang has now disappeared. If I type in "clang --version", 
I get "command not found". "whereis clang" only gives me the library 
dir. Doing "ls -la /usr/bin/cla*" gives me "No such file or directory"


	I've run the install several times. I've even uninstalled both clang 
and llvm and then reinstalled and still the same. The only thing that I 
can think of is that whilst doing the original update, for some reason 
my machine crashed during the clang install. This may have screwed 
something up.


	Has anyone managed to do the install/update and have a working latest 
clang?


Thoughts/comments greatly appreciated,

Andrew

p.s. Looking in the /usr/lib64/clang/4.0.0 dir shows plenty of libraries 
in there.
