What i don't like about dub is that is does not check which software is
installed on the host.
Currentlu tck86 is installed on the host including header files & shared
libraries.
But dub says let me just download my own personal version and i will
compile it in your home directory
/home/myuser/.dub
There is something inherently wrong in doing so.
Note other package managers of different languages do the same thing.
dub should really check if something should really be downloaded.
Otherwise you end up in a library hell, in Gates words known as dll hell.
If I understand correctly, you have a library that is already installed
on your system (is it tcl86? I couldn't find a tck86), and you want to
use it's headers and library file? Yet, the dub package you are
depending on is downloading its own copy?
1. Are the installed headers D headers? D can't currently reasonably use
C headers. I don't know of D bindings that are installed by OS package
managers.
2. Is the package maybe downloading a binary library to avoid having to
ask users to install their own copy? This is something you need to bring
up to the package developer, it's not a dub feature. Also, if there are
differences between the C bindings of the version you have installed and
the version the package is expecting, you are in for some trouble, so
that may be a valid reason to include the binary.
Since this is a package issue, and not a dub issue, I'd recommend
posting the package you are using, and maybe contact its author.
