Details

Description:

I think currently the -fPIC changes have been propagated to testing. This breaks the dlang packages as they haven't been rebuilt, e.g.

fsmfzweyguhqvsqudbqg@forum.dlang.org"> http://forum.dlang.org/post/fsmfzweyguhqvsqudbqg@forum.dlang.org
gpbyhmdsudlmapsvvqmq@forum.dlang.org"> http://forum.dlang.org/post/gpbyhmdsudlmapsvvqmq@forum.dlang.org

It would be very nice if the packages could be rebuilt with fPIC enabled.
Currently this can be done by passing PIC=1 to make.
However, it could be become the default in the future (it already is in the default flags file of dmd):

https://github.com/dlang/phobos/pull/5586

Additional info:
* dmd 2.074.0
This task depends upon

Thanks a lot for the fast reply and considering this in your recompile list. Could you please add ldc [1] to the recompile tasklist as well? Thanks!

ldc is already built with PIC, what is the issue with it?

AFAICT you simply don't ship a static library with the ldc meta package (-> liblphobos), in other words this currently fails:

> echo 'void main(string[] args) { import std.stdio; writeln("Hello D");}' > hello.d
> ldc -static hello.d


The release binaries of ldc [2] ship with a static library.

Right, Arch doesn't provide static libs if there is a shared version. In any case - this is unrelated to the original report.
