This is mainly to help along discussion of language features and to see what fundamental issues I've overlooked! ftp://ftp.digitalmars.com/dmdalpha.zip Enjoy. -Walter |

I'm absolutely interested in any and all bug reports. Post away, there's nothing secret here! As for the bugs listed in the doc, I'm interested in what priorities people have for them. I need to get it whipped into shape before my DDJ article on D gets published! -Walter |

Posted in reply to Walter | Bug 0002: Link problems I compiled the following source file, wanting to test out how the GC works: import stdio; class Foo { static this() { printf("%p ",this); } ~this () { printf("~%p ",this); } } int main() { { Foo ptr = new Foo; printf("x"); } printf("x"); long i; for(i=0; i<1000*1000*1000; i++); printf("x"); return 0; } My makefile was as follows: russ.exe: russ.obj link ..\lib\phobos.lib ..\lib\snn.lib russ.obj russ.obj: russ.d mars russ.d -I..\src\phobos I get the following errors on the link: link ..\lib\phobos.lib ..\lib\snn.lib russ.obj OPTLINK (R) for Win32 Release 7.50B1 Copyright (C) Digital Mars 1989 - 2001 All Rights Reserved ..\lib\snn.lib(stream) Offset 3CFB1H Record Type 00C3 Error 1: Previous Definition Different : ?WS@@YAAAVistream@@AAV1@@Z (istream &c decl WS(istream &)) ..\lib\snn.lib(_wfopen) Offset 51C1DH Record Type 00C3 Error 1: Previous Definition Different : __WFOPEN ..\lib\snn.lib(wconstar) Error 42: Symbol Undefined _wmain ..\lib\snn.lib(wwinstar) Error 42: Symbol Undefined _wWinMain@16 ..\lib\snn.lib(winstart) Error 42: Symbol Undefined _WinMain@16 --- errorlevel 5 I have never used DM compilers before, so I downloaded dm823c.zip, extracted it, dmdalpha.zip and extracted it, and then copied all the files in the dmd/ directory over into the corresponding ones in dm/ -- The Villagers are Online! http://villagersonline.com .[ (the fox.(quick,brown)) jumped.over(the dog.lazy) ] .[ (a version.of(English).(precise.more)) is(possible) ] ?[ you want.to(help(develop(it))) ] |
December 09, 2001 Bug 0003: Illegal Operation when compiling a .d file with a .lib file | ||||
---|---|---|---|---|
| ||||
Posted in reply to Walter | I tried to use the compiler to link in a .lib file with something I was compiling, since I've seen that done on gcc. I don't know if the DM d compiler supports that sort of thing, but instead of reporting an error I get an "Illegal Operation" window with the following line: mars russ.d -I..\src\phobos ..\lib\phobos.lib -- The Villagers are Online! http://villagersonline.com .[ (the fox.(quick,brown)) jumped.over(the dog.lazy) ] .[ (a version.of(English).(precise.more)) is(possible) ] ?[ you want.to(help(develop(it))) ] |

I might be wrong, but AFAIK VC++ doesn't allow such things. Borland compilers do. Is it in ANSI C++ or not, I wonder? Not sure I'd like to see it be legal in D, anyhow. |

I had modified the program a little: import stdio; class Foo { this() { printf("%p created\n", this); } ~this() { printf("%p destroyed\n", this); } } int main() { { Foo ptr = new Foo; printf("ptr %p out of scope\n", ptr); ptr = cast(Foo) null; // no effect } printf("waiting for gc...\n"); for (long i = 0; i < 1000*1000; i++); printf("done\n"); return 0; } Now when I run it, Foo gets created but is never destroyed, even with 1000000000 iterations of loop! Shouldn't the GC run at the end of the program anyhow? Also note one weird thing. null is a void*, and is incompatible with any other pointers, requiring explicit cast! This should definitely be changed... |

Anyhow, you should do it when linking: mars russ.d -I..\src\phobos sc russ.obj phobos.lib |

Posted in reply to Walter | Program consists of two files: // mod1.d import mod2; char[] name() { return "EvilOne"; } int main(char[][] args) { greet(); } // mod2.d import mod1; import stdio; void greet() { printf(name()); } First, I've compiled it as follows (repeating -I stuff omitted): > mars mod1.d mod2.d mod1.d(10): undefined identifier greet OK, now vice-versa: > mars mod2.d mod1.d mod2.d(7): undefined identifier name Then I decided to compile them separately: > mars mod1.d !!!Works!!! > mars mod2.d Internal error: ..\ztc\cgcs.c 348 Here, the order doesn't matter. mod2 always fails to compile.
