I'm running Fedora 13.x86_64 and I've tried various ways of getting a
D compiler to work. None have succeeded.
1. a. I can't install dmd 2.048:
# rpm -Uvh /downloads/dmd-2.048-0.i386.rpm
error: Failed dependencies:
gcc(x86-32) >= 4.2.3 is needed by dmd-2.048-0.i386
I don't know what package will satisfy this dependency.
b. dmd is a closed compiler. Not good. I'm really not comfortable
running a compiler for which I don't have access to the source. The
risk of undetected malware is too great.
c. So, I give up on dmd.
Because DMD is a 32-bit compiler and you have a 64-bit OS install ?
yum whatprovides "gcc(x86-32)" tells (or rpm --aid -Uvh before it).
Currently gcc-4.4.4-10.fc13.i686.rpm provides the dependency, to
use --aid you need rpmdb-fedora and a RPM version that supports it.
2. I can't run ldc because
a. The ldc RPM requires Tango, even though this is not an RPM
dependency for ldc, i.e. you can install ldc without any errors.
b. The installation instructions for Fedora on the LDC web site are
incorrect. "yum install ldc" works, but "yum install tango" doesn't.
"yum install tango-devel" is the correct command. (This is the first
time I've heard of <pkg>-devel without a corresponding <pkg>.)
This is because Tango (or Phobos) only provides static libraries,
if there had been a shared library it would have been "tango"...
In the previous packaging one of the "runtime" library providers
were required, since the compiler is not very useful without one.
c. After I've gotten everything installed, it still doesn't work. I get
$ ldc hello.d
hello.d(5): Error: module stdio cannot read file 'std/stdio.d'
d. OK, so I link /usr/include/d/tango/stdc to
/usr/include/d/tango/std, but it still doesn't work. I get:
$ ldc hello.d
hello.d(8): Error: undefined identifier writefln
hello.d(8): Error: function expected before (), not writefln
of type int
e. ldc only supports D v1.
f. All of this is too much for me. I give up on ldc.
But LDC is the D compiler that Fedora has chosen for inclusion in 14...
See https://fedoraproject.org/wiki/Features/D_Programming for details.
3. I can't get gdc to compile.
a. First I have to get gcc-4.4.4 to compile, but that requires a 4
year old version of automake. I have to downgrade.
b. After that's fixed, I'm still running into errors that prevent a
build. The errors change from changeset to changeset. So, I'm giving
up on gdc.
If you use an older GCC, it is much easier. (GCC 4.1.2 was supported)
There's some GDC packages available at http://gdcgnu.sourceforge.net/
Getting a D compiler to run on x86_64 Linux is too hard. I'm giving up
on D.
Seems like you ran into these, all at once:
- 32-bit compiler
- static runtime
- wrong stdlib
- older version
Some of these will be fixed, when/if updated.
