dev-lang/dmd circular dependencies

[akbarstatix]

Hi I am trying to emerge dev-lang/dmd from the dlang overlay but I am stuck. I am getting errors about circular dependencies.  I have my use flag set to, dev-lang/dmd dmd-2_068 package.use file.

quad portage # emerge -auvDN =dev-lang/dmd-2.068.2-r1

 * IMPORTANT: 3 news items need reading for repository 'gentoo'.
 * Use eselect news read to view new items.


These are the packages that would be merged, in order:

 * Note that circular dependencies can often be avoided by temporarily
 * disabling USE flags that trigger optional dependencies.

After adding dlang overlay to a current amd64 system I see the same errors as you when trying to emerge dev-lang/dmd.

Not knowing how to resolve those errors I decided to try merging lower versions of dmd. 

* dev-lang/dmd [1]
     Available versions:  
     ((get_version_component_range 1-2)) 2.063.2^m 2.065.0^m 2.066.1^m 2.067.1^m (~)2.068.2-r1^m (~)2.069.0_beta2^m
     (2.064) 2.064.2^m
       {doc examples tools}
     Homepage:            http://dlang.org/
     Description:         Reference compiler for the D programming language

[1] "dlang" /var/lib/layman/dlang

dmd-2.068.2-r1 produces same errors as dmd-2.069.0_beta2.

dmd-2.067.1 has no errors and may build.

If this doesn't work for you file a report at bugs.funtoo.org

funtoo rj # emerge -pv =dev-lang/dmd-2.067.1

These are the packages that would be merged, in order:

The dev-lang/dmd-2.068.2-r1.ebuild here https://raw.githubusercontent.com/gentoo-mirror/dlang/master/dev-lang/dmd/dmd-2.068.2-r1.ebuild

IUSE="doc examples tools"

I don't know what side effect and point of adding use flags to package.use that don't exist on the ebuild.

System USE flags are listed here:  /usr/portage/profiles/use.desc

Package name and versions are never USE flags.

Remove any USE flags from /etc/portage/make.conf USE="" that are not on the use.desc list.

Maybe adding the name program-version as USE flags to package.use that don't exist on the ebuild is causing the error?

USE="dmd-2_068 -dmd-2_063 -dmd-2_064 -dmd-2_065 -dmd-2_066 -dmd-2_067 -dmd-2_069 -doc -examples -gdc-4_8_1 -gdc-4_8_2 -gdc-4_8_3 -gdc-4_8_4 -ldc2-0_12 -ldc2-0_13 -ldc2-0_14 -ldc2-0_15 -ldc2-0_16 -tools"

 

Remove  

Remove everything from dev-lang/dmd dmd-2_068 package.use or from except use flags that exist on ebuild:

-doc -examples -tools

emerge -av dmd

I should have mentioned that my first attempt was installing without any use flags specified.   Here is the result emerging without any user added use flags:

quad ~ # emerge -auvDN dmd

 * IMPORTANT: 3 news items need reading for repository 'gentoo'.
 * Use eselect news read to view new items.
