Hi all.

Until last week I used DIDE for developing my project. Because project growth recompiling it each time became annoying, so I decide to use PN2 as editor and SCons system as builder. I wrote SConscripts, etc, etc, and try to compile. All fine, all compiles but I've got some errors on link step. Something ala

src\rame\graphics\rsgl.obj(rsgl)
Error 42: Symbol Undefined
__init_52TypeInfo_C4rame8graphics12rendertarget12ColorBuffer

I could not understand the reason for several days: all modules present, all classes are implemented, etc. Today I spoted a problem and made exaple project that models this situation:

>>>>>>>>>>>> classes.d
module classes;

class A
{
int a;
}

>>>>>>>>>>>> templ.d
module templ;

class TemplateClass(T)
{
static const TypeInfo ti = typeid(T);
}

>>>>>>>>>>>> core.d
module core;
private import templ;
private import classes;

int main(char[][] args)
{
TemplateClass!(A) tc = new TemplateClass!(A)();

return 0;
}

>>>>>>>>>>>>> SConstruct
Program("test", ['core.d', 'templ.d', 'classes.d'])



Build output is:
D:\dtest>scons
scons: Reading SConscript files ...
scons: done reading SConscript files.

As you can see linker reports every class that will be transmited to
TemplateClass as template parameter as undefined symbol.
static const TypeInfo ti = typeid(T); line invokes this strange behaviour.

I think this is a bug. But maybe I didn't understand something?

I have had what looks to be the same problem with the mintl library. It only happens for me when I templatize a mintl SortedAA on a function delegate. For example, this code fails to link:

module test;

import mintl.sortedaa;

SortedAA!(char[],void delegate()) foo1;

int main()
{
  return 0;
}

Compiler output:
[baron@athe bug1]$ dmd test1.d -I../../include/phobos/ -I../../include ../../lib/libmintl.a
gcc test1.o -o test1 ../../lib/libmintl.a -lphobos -lpthread -lm
/usr/bin/ld: Warning: size of symbol `_D3std6stdarg9va_arg_Aa6va_argFKPvZAa' changed from 23 in test1.o to 34 in /usr/local/lib/libphobos.a(format.o)

: undefined reference to `_init_13TypeInfo_DFZv'
collect2: ld returned 1 exit status

This is in linux, and it also fails to find an init TypeInfo instance. But if you insert a line like this in the single source file it will link.

TypeInfo info=typeid(void delegate());

I'm glad you were able to track it down with more detail than I was. This has kept me from using mintl for now. :(

Walter, any ideas on this one? Thanks!

- Doctor, doctor, everybody ignores me.
- The next, please. :)

Nobody collide with this problem? Maybe the sequence of dmd commands is wrong?

Can you give me the url for download DIDE?
I went to the mainpage but found nothing to download
