Please note, the last time I checked, dmd is built in debug mode by
default.  Not sure if this has changed, but if you are getting weird
extraneous message, that's probably why.

I think you have to do make release, or something like that.


Looking at the output of
$ make -f linux.mak
and inside linux.mak it seems that is not a debug build.
But thanks anyway.


Hm... it may be only windows that builds debug by default.  Though I can't  
see a good reason for the difference.

I needed to build 64 bit because my Linux ships no 32-bit libcurl and I
don't want to build that as well. I had to add a symbolic link from
libcurl.so.4 to libcurl.so. Don't know why it wasn't there. It should
have, shouldn't it.

BTW I see --- std.regex(3443) broken test ---
The code is
unittest
{
// DAC: This doesn't create the file before running the test!
pragma(msg,  --- std.regex(~ __LINE__.stringof ~) broken test --- );
/+  
string tmp = /tmp/deleteme;
std.file.write(tmp, 1 abc\n2 defg\n3 hijklm);
auto t = loadFile!(uint, string)(tmp, regex(([0-9])+ +(.+)));
//writeln(t);
assert(t[0] == tuple(1, abc));
assert(t[1] == tuple(2, defg));
assert(t[2] == tuple(3, hijklm));
+/
}

I do not understand that comment. I ran this test by commenting in the
code and it worked.

Maybe even better using a temporary file like this
auto file = File.tmpfile();
file.write(1 abc\n2 defg\n3 hijklm);
file.rewind();
auto t = loadFile!(uint, string)(file, regex(([0-9])+ +(.+)));
//writeln(t);
assert(t[0] == tuple(1, abc));
assert(t[1] == tuple(2, defg));
assert(t[2] == tuple(3, hijklm));

Because I have seen the auto-tester failing because of forgotten files.
A good test shouldn't leave any trace if it was successful. Every change
may cause another test to behave differently. Tests should be isolated
as much as possible. Thus, not influencing each other. There may be
cases where one wants to influence another test but these are very rare
I guess.

Forking phobos

2011-04-03 Thread Aleksandar Ružičić 
I want to fork Phobos and hack a bit on it (maybe even submit some
pull requests, someday), but I'm having trouble compiling it (on
windows).
This is what I've done:

 - forked phobos on github
 - cloned the fork to my machine
 - run make -f win32.mak

and make complained that it can't make druntime lib. So I've cloned
druntime in same directory where i have phobos (so I now have phobos
and druntime directories on same level),
Did make -f win32.mak clean and tried make again, but it still
complains about druntime:

cd ..\..\..
Error: don't know how to make '..\druntime\lib\druntime.lib'

What I'm I doing wrong? Am I missing some more components?
I just want to be able to edit phobos source, compile it to phobos.lib
and link it to my d program.

I have DMC, DMD and LINK on PATH, that's not the issue...


Thanks,
Aleksandar

I believe that these are the correct steps:

1. Make sure that druntime and phobos were both put at the same directory 
level. e.g. I have C:/github/druntime and C:/github/phobos.

2. Adjust your sc.ini accordingly. e.g. Mine is

=
[Version]
version=7.51 Build 020

[Environment]
LIB=c:\github\druntime\lib;c:\github\phobos\;c:\dmd2\windows\lib;c:
\dm\lib
DFLAGS=-Ic:\github\phobos\;c:\github\druntime\import
LINKCMD=%@P%\link.exe

3. Build druntime by running make -f win32.mak in the druntime directory.

4. Build Phobos by running make -f win32.mak in the phobos directory.

That's interesting. I'm on Linux. I tried running druntime's unittests

some local setup problem. But now I see that the problem must be

  That's interesting. I'm on Linux. I tried running druntime's unittests
  some days ago and I had a very similar problem. I assumed this must be
  some local setup problem. But now I see that the problem must be
  somewhere else. I have the same undefined references
  _D4core5bitop3bsfFNaNbkZi as you.

  How come that the auto-tester (http://d.puremagic.com/test-results/)
  does not have this problem? Does the auto-tester use the dmd it is
  building?
