gcc upgrade

Hu,
What I did is following:
I started Anjuta, created a project and couple of libraries projects.
Added the source code compiled it and then use the "Install" feature from Anjuta.
The Anjuta IDE was installed as is from the Portage and I would be surprised if it did something non-stanhdard.

Now back to my original question - I thought that in order to make baselayout happy and make it installed all I need to do is to create such a symlink.
If not - than I don't understand why the symlink is even popping up here.

Thank you.

Hu, I think he is saying that he is building and installing outside of portage. Many packages install into /usr/local/bin and /usr/local/lib instead of /usr/bin and /usr/lib if the distro's package manager isn't used. It may or may not be correct procedure but it is common.

ONEEYEDMAN, I strongly suggest building with portage from the beginning using an overlay in /usr/local/portage. If you don't, you wind up with conflicts because of install scripts spraying files all over. If you use portage, even if the files are misplaced, portage knows where it put them and can remove them.

Tony0945,
As I said I am still developing and so this software is WIP. And so can't be installed thru the Portage.
Unfortunately it looks like an update somewhere broke the system and make it in an un-usable state, so that the next update is not possible. This is the only sane explanation I have right now. Because it seems that /usr/local/lib has to be a symlink to /usr/lib{64} and /usr/local/bin to /usr/bin. Because I check another install of Gentoo and this is the way it is set up
But the latest reply from Hu indicates that this is wrong fix.

I wonder why?

Thank you.

Hi, guys,
@John,
So even on the early stages of your development you using the ebuild?
I'm trying to create a cross-platform DB handler software in C++.

@Hu,
For now I want my system to become sane. I can fix the names of the libraries later when the software is ready to be released.

Thank you.

@John,
I was told that I can't run the software from Anjuta from the build directory.
Anjuta developers told me that I have to install the binary executable and all libraries I produce in order to run/debug the software from Anjuta.

I can try to dig up that E-mail if needed.

So I'm just following that suggestion.

Thank you.

Then under those circumstances I would definitely create an ebuild to track the installation.

I just took a look at the only anjuta ebuild in the tree. Nothing really weird. it should be easy to clone and modify.

EDIT:
As long as you type better than me!

Hi,guys,
@Tony0945,
It is not about ebuild. As far as I understand Anjuta is written so that when you try to debug or run the binary you just build from inside Anjuta, it looks in the standard /usr/{local/}lib{64} tree for all so libraries it linked to. Simply because it probably relies on the lddconfig output.
That is my understanding.

So the ebuild is fine - its Anjuta source code that needs fixing.
Unfortunately I'm not really great with GTK+ programming to find where and what needs to be changed.

@John,
The problem at hand is not the {bad} names of the libraries - it is baselayout installation (see above). So this /usr/local/lib not being a symlink should be fixed somehow.
It is Hu who tried to move this thread away from the point/problem I'm trying to solve - make the system sane so that I can rebuild wx and my software and continue the development process.

Thank you.

Strictly speaking, I tried to solve both your stated problem (and did), and your unreported problem (bad installation) which I expect will cause you trouble eventually.

/usr/local/lib should not be a symlink to /usr/lib but to /usr/local/lib64. Fortunately I switched to the 17.1 profile, and this annoyance is history. Personally I still do install certain things to /usr/local. You just have to know what you are doing.

To come back to your original problem: The latest change of math.h indicates that the change of the default C++ mode in gcc-6 is the cause of your problem.

Hi,
OK, I pass baselayout, but now have a different issue:
