digitalmars.D - Unable to build deimos/libX11 with ldc2

reply "Paul Z. Barsan" <paulmegabyte gmail.com> writes:
    I got ldc2 from github and built it following this tutorial: 
http://wiki.dlang.org/Building_LDC_from_source . The ldc build 
and install went fine but when I try to build libX11 with it, I 
get the following errors:

$make -j2
sh: arch: command not found

Any clues ?

Without having looked at the libX11 sources at all, the error 
message implies that there are multiple "extern(C)" function 
declarations named Data that have different types. This is likely 
an issue with the libX11 bindings and should be fixed there.

DMD doesn't care about that, but in LDC we would have to 
specifically work around a related LLVM "restriction" to be able 
to accept that code.

Oh, and in the future, you might want to post similar questions 
to digitalmars.D.learn.

Oh, sorry for using the wrong forum section.

I used the dmd compiler and the build went fine. Is pretty weird 
though because ldc2 is the default compiler used to build libX11. 
I filed an issue report for deimos/libX11 on their project page.

BTW what do you plan to do with the libx11? You might find my 
simpledisplay.d (also depends on color.d) interesting from my 
miscellaneous github:

https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff

It provides a class called SimpleWindow that supports basic 
drawing and some input stuff (input is in the middle of an 
overhaul right now, I'm fixing a lot of bugs and will be posting 
that new code online in a few days, but even right now it still 
works for checking ascii keys at least), on top of Xlib, with 
equivalent code for Windows in there too so your same program can 
compile cross platform.

Though I've never tried to compile it on ldc either, I did my own 
xlib bindings (included in the same simpledisplay.d file) so it 
might work; surely won't have the *same* bugs at least.

It's a dependency for Cairo. I want to use Cairo for drawing 
stuff on the screen. This library is also used by GTK 3 to render 
all their widgets.Besides that, it supports multiple platforms :).

I started my widget toolkit project on github: 
https://github.com/tyrolite/wkd and I'll make an anouncement on 
the other thread once I have the code to draw a button. I'll 
probably get faster there using parts of your code.

Thanks !
