In the error noted above however the "ld" cannot find it. Now without all the

I have tried copying bth the libm file and link into /usr/lib to no avail.

If it seems like I am rude ,it is because I have been on this ,on and off for

Hi Ty,

Have you got the static variants of those libraries installed? (i.e.
libm.a)  Seems you are doing a static link using dynamic libraries..

On Debian, these are found in package "libc6-dev", other distros will
have them elsewhere.

Thanks David . No I have only the .so. version. I am intrigued by your comment that I am doing a static link using dynamic libraries . Can you expand on that please . How would the command line change to use dynamic libraries? Rather than do a lot of typing can you point me to a site that explains the difference ?

On Linux, linking is exactly the same for static and dynamic libraries. This is one of the advantages of the linux system. There is no dll or import library complexity to deal with as there is on Windows. The difference with the developer packages is that they usually supply both the static and dynamic libs without the postfix version numbers, They also supply the necessary C headers and documentation. Some Linux distributions include the developer versions of the libraries by default. Other distributions do not. Ty might have to download these libs to get things working... which would explain a lot of the problems he's been having. I notice also that the command line error complained "/usr/bin/ld: cannot find -lm" which is odd. It seems to be not interpreting the commandline flag: I would expect it to say "cannot find libm.a (or libm.so). But I'm not certain. Nonetheless the compiler is looking for the the non-version decorated libm and cannot find it. Incidentally, libm is the default math library on linux. Most linux should have it installed. The developer lib package may be necessary to access this library directly, but even then one could access the non-developer version simply by making a symbolic link to the versioned one in the lib directory where it resides. Or one could even provide the full path the the versioned library on the command line to achieve the same thing. But instead of fiddling with the system, the user should just download the necessary developer version of these libraries. Part of these problems seem to be that Ty is unfamiliar with linux, or, at least, linux development. If this is the case, there is a LOT more to help out with then just dmd/dwt related issues. Linux is not an easy system to learn to program on since there are many tools with which to get familiar. Thus, we must assume, to some extent, that the dwt user has some familiarity with the system he develops on. It would horribly time-consuming otherwise to have to step the user through platform development peculiarities and linux administration. Thankfully, we don't have to do that... since there appears to be an amazing supply of very accommodating and knowledgeable people here. But I do think it is unfair to assume we owe such a user all our time and attention for such details. -JJR

You assume a lot . and incorrectly at that . I have a fairly intimate knowledge of Linux but this I have not seen before.

If you look at the example program "helloworld1.d"which I will attach here , there are a lot of problems in dwt .

Okay. I don't know why there isn't a libm.so sym-link to these libs than. Try making one and see what happens.

Okay. Perhaps I assumed wrong, but it appeared otherwise. I thought most linux developers understood that linking to a static or dynamic library was achieved the same way on linux (with the -l switch). Incidentally, I do not claim to have an intimate knowledge of linux developement or linux. I do have a comfortable working knowledge of it, however.

This is not clearly a dwt issue, so I won't (or shouldn't) devote more time to postulating why -lm is not found. That would be futile for me at this point. You are correct that I spent too much time typing a post in such quantity (including this one). libm is a dependency that the dmd compiler adds to the command-line, and this has been so for a long time. So if it isn't working right now, I wouldn't blame it on dwt just because this is the library you are trying to use right now. I'd tend to look further into why dmd is not working. Furthermore, I have no idea why one needs to add the Tango imports to get things linking correctly. I suggest you ditch dwt from your system and test dmd/dsss/Tango (or perhaps Phobos first) rigorously before you even approach dwt again.
 I have tried putting /lib/ in front of my PATH and also at the end to no
avail. I have copied both file and link to /usr/lib aain to no avaail . This is
my $PATH  
 PATH=/lib:./:/usr/bin:/bin:/usr/local/bin:/usr/X11R6/bin/:/usr/games:/usr/lib/qt3/bin:/usr/lib/qt3/bin:/usr/lib/qt3/bin:/usr/local/:/usr/local/lib:/usr/include:/lib
 When I find the cause for the triple qt entry I'll be in heaven.
 
These are all linux issues (or dmd setup issues). If these cannot be straightened out, I can't help.
 I'm starting to think the library may have been corrupted somehow. Have you
had any reports of file corruption by dmd or dsss?
 
 
No. It's very unlikely libm could get corrupted by dmd or dsss... unless you run linux as the superuser all the time (which would be a bad idea). Even then, I don't know why dmd or dsss would do such a thing. Your whole linux distribution would be compromised if they could or did. Even so, ld would probably report the error if libm was corrupt. Maybe a reinstall of your Linux distribution or a different distribution might be the answer. That may seem like a lame suggestion to you; but sadly, this is becoming the best I've got. -JJR

That's from the glibc package. You must also install the glibc-devel package. If you have, there should be a /usr/lib/libm.so (which should be a symlink to one of the others). If this symlink is not there, I suggest reinstalling glibc-devel. You might also want to try "rpm -V glibc-devel" to make sure that your install has not been corrupted somehow.

I am confused on your accusation here, are you saying that my posts have no thought because I don't read your posts? If that is your claim it is a lie, as I have read ever post of yours and every post replying to your posts. Not only that, but I have compared my own knowledge with those responses to see if anything needed corrected or added. I have even taken time to see how accurate your accusations have been. I feel I have put a lot of thought into my posts. As stated before, your last posted problem is not a step forward. Running into an inability find a needed linked file is at the first stages of linking. Your other problems had already gone past this stage and run into duplicate definitions. The last think you bring up is that most of my posts have been to "knock" yours. This first group has been purely help: http://www.digitalmars.com/webnews/newsgroups.php? art_group=digitalmars.D.dwt&article_id=623 http://www.digitalmars.com/webnews/newsgroups.php? art_group=digitalmars.D.dwt&article_id=636 http://www.digitalmars.com/webnews/newsgroups.php? art_group=digitalmars.D.dwt&article_id=681 http://www.digitalmars.com/webnews/newsgroups.php? art_group=digitalmars.D.dwt&article_id=722 Then we have the group of informative and "knocking," the last on starting with help, but mostly explaining way we made suggestions, after having been accused of not putting thoughts into our posts. http://www.digitalmars.com/webnews/newsgroups.php? art_group=digitalmars.D.dwt&article_id=662 http://www.digitalmars.com/webnews/newsgroups.php? art_group=digitalmars.D.dwt&article_id=733 This final group has provided you with no help, but instead trying to demonstrate that your frustration with our help has been related own misunderstanding of the problem and not ours. http://www.digitalmars.com/webnews/newsgroups.php? art_group=digitalmars.D.dwt&article_id=740 And of course this Current post. These post have come about not because of your still needing help, or creating new problems, but because of your continued hostility to those that have already provided you with help. As I do not want to be accused of not thinking I will have to explain way said line is hostile: "Probably any one of you could have explained this had you trie a little harder ." You say we just needed to try a little harder. This would suggest that if we looked at the output from your command we could have explained why you might have been missing -lm. This conclusion is supported by the added: "Now without all the other extraneous b/s of versions etc , surely someone can suggest why this might be." Now had you politely return here with this new problem requesting help, I would have seen no reason to have corrected you incorrect accusation. I set for to correct this by providing all of the output you gave us, to show you that at no point did a problem with -lm show up. I ask how does that not show thought? In final hopes of resolution, you will note that only with this post have I hit the 50/50 mark for hostile postings. I suppose to round this off as hostile, I could through in the hostile postings you have had, but I did not see that as the purpose of this posting.

You may think so but this guy has been following my posts and posting without a lot of thought merely to have a shot . Bit of a paranoid I think to look at the time spent quoting other posts. When you look closely at his posts in this thread they are mostly wrong and rubbish - something wrong with him- There is a limit to being polite.

Could not find reference to needed libraries, you used dmd instead of
dsss or rebuild, so the proper -l flags were not added.

Just in passing I do not agree with this .There is no reason dmd would not add
the correct libraries
Prove it .

Prove it? Prove that dmd does not guess which libraries you need? There's nothing to prove. DMD includes the libraries listed in your sc.ini and the source files and libs you list on the command line. Nothing else. If you want to link with anything besides those, you have to list it yourself. Or use DSSS. --bb

Yeh, I just wasn't going to recommend that because I haven't personally tried to build DWT with bud. And I don't think it's mentioned in the DWT readme currently either. But yeh, in theory Bud should work. --bb

You mentioned in another post that you are still working on bud, but you haven't updated svn. Is there a more recent build of bud that we can get a hold of? I wouldn't mind giving it a try again. -JJR

I'm a lucky guy :-) After saying I'd work on it last night, I get a call from a customer saying that they have a big problem and thus now so do I. It positively absolutely has to be fixed RIGHT NOW! So I work at it and sometime around 11:30pm I finish. It's now the next day and I'm waiting for them to say everything's alright. I haven't heard from all day them so I'm guessing things can't be too bad ... maybe I should call anyways. Also, Walter has now delivered DMD 2.011 so I have to recompile and fix up the 'gotchas' again. Maybe tonight ... or maybe I'll just hide away and play some CoD4 online :LOL: -- Derek (skype: derek.j.parnell) Melbourne, Australia 20/02/2008 4:36:40 PM

I use windows mostly, but I can tell you emphatically that those two absolutely do *not* do the same thing on Windows. First off, dsss build /Mysuff/main.d will just die with an error if you haven't made a dsss.conf for it. Second, assuming you do have a dsss.conf, dsss build scans main.d for any 'import' statements, and adds those files to the list of things to compile and link with. Likewise it adds the imports of those imports, and so on recursively. 'dmd' does none of that. It just compiles and tries to link main.d into an executable, including a few default standard libs listed in sc.ini. I don't know what dmd.conf is. All this is on Windows. And I'd be surprised if it was radically different on Linux. --bb

Right Bill thats what I need, On Linux dmd.conf I think is much the same as sc.ini on windows I have a dsss.conf file for it and the output of both, I must admit, is different and maybe with that piece of info I can progress further. Bloody Tango /Phobos. Thanks

You don't need a dsss.conf file you you run dsss with the command "dsss build target", you need a dsss.conf file if you run dsss with the command "dsss build"

Is that so? I don't think that used to be the case... Oh, I see. For that to work you have to include the ".d" in the name. So "dsss build target.d". Otherwise you get "target is not described in the configuration file." You don't need the .d if the target is in a dsss.conf, so I don't usually type it. Good to know. --bb

I wrote "target" and not "target.d" because you can have a directory as target and I assume that it also works without a dsss.conf file

I was wondering about this too, so I just tested it. Seems that you don't need a dsss.conf to build stuff. But if there is one in the current dir, you can't build anything not listed in it. So it's one or the other.

Why do you keep insisting on using only dmd and not dsss? DSSS is a great tool that will help you a lot when you compile D code. You can also download, build and install D related applications and libraries with just one command, like ruby gems if you are familiar with that. I see no reason not to use it.
