configure error: C compiler cannot create executables

Doug Orleans — 2008-08-29T16:56:31

Hi, I recently reinstalled Ubuntu 8.04 from DVD. I checked out the PLT trunk from Subversion, but when I run configure I get this error: dougo< at >quiet:/usr/local/plt/src$ ./configure checking for gcc... gcc checking for C compiler default output file name... configure: error: C compiler cannot create executables See `config.log' for more details.

Right. A time-compat..sls file supplies a time macro which may be a "dummy", depending on . The R6RS test suite code which runs on all implementations includes "the" time-compat.sls library, uses the time macro, and its code does not change. I think we are "agreeing loudly" here using different words. Right? -KenD _________________________________________________ For list-related administrative tasks: http://list.cs.brown.edu/mailman/listinfo/plt-scheme

Thanks again guys for your help in this I *really* appreciate it. Let me know if you are coming to London so I can make it up to you. Back to the problem; I'm confused that it is working for Grant, because while I have made considerable changes, I didn't think anything in the code would affect the documentation. (I even renamed the scribble file to avoid what I thought was a possible name collision problem) I've zipped the source at http://projects-project.googlecode.com/files/projectmgr.zip On Fri, Aug 29, 2008 at 4:56 AM, Robby Findler public.gmane.org> wrote: I've downloaded the latest overnight plt-full, reset all my config files back to the default and renamed the .scrbl file - the old error has been replaced your one; uclic36:~/Documents/Development/scheme/subversion/projects-project stephen$ planet create projectmgr Building: notes.scrbl PLaneT packager: Error generating scribble documentation: main-doc-relative->path: expected argument of type ; given (#) Refusing to continue packaging. uclic36:~/Documents/Development/scheme/subversion/projects-project stephen$ (I've switched machines to a 10.4 intel mac too) Sorry, I don't get your stake trace - I may be doing something wrong.

Re: r6rs timer

Jos Koot — 2008-08-29T07:08:01

Many thanks. Very clear. When I said R6RS conformant, I ment source code that runs on all R6RS implementations, not restricted to PLT only. The two R6RS documents do mention "time" in their indices, nor anything alike. Hence when using "time" in a performance test suit, I must include a dummy time macro, which I replace by an import from scheme/base when running with PLT. When the user runs the code with another implementation that does provide a timer, she may replace the dummy macro by an import of that timer. When the user runs the code with an implementation that does not provide a timer, the dummy time macro evaluates its expression without producing timing info.

I've improved planet's error handling in SVN and here is the current error message, now with stack trace information (this error message is different, I guess because I'm running a newer version of PLT Scheme than you are Stephen?). I don't know what this error message, but the stack trace indicates to me that it is at least a missing check earlier? Does that seem right?

Re: Cleanup on Servlet Timeout (Again)

Matthew Flatt — 2008-08-28T09:23:01

That's true. That sounds like the right solution to me. Why not? More generally, you could run it in any thread that has the same capability to run as the server thread --- perhaps another thread that is created when the web server is started. Using the FFI, you could call scheme_start_atomic() and scheme_end_atomic(), but I recommend the other approach. A comment on your version of the code: A writer posts to `fail-s' even after succeeding and posting to `done-s'. When both semaphores are posted, there's no guarantee that the server will see `done-s' before `fail-s', since it `sync's on both at the same time. That is, if both are available before the server actually picks (perhaps even before the server manages to call the `sync' function), then it might pick `fail-s' even though `done-s' is available. Also, you still need to use something like `reply' instead of `channel-put' to accept a reader/writer, but I think you know about that problem (and probably you're waiting to create a test that demonstrates the problem before fixing it).

Thanks! In the text of bug reports, I often write snippets of code. With Trac you can write preformatted text by writing: {{{ (define foo 42) }}} But with the right plugins, you can also write: {{{ #!scheme (define foo 42) }}} and it formats the text nicely.

Re: PLaneT bug tracking

Robby Findler — 2008-08-28T20:56:29

I didn't see a very good way to do this, so I've added a dummy component that I'm responsible for, and made that the default. (I also fixed planet's interface to trac so that the right component is selected by default when you come from a planet package page.) There doesn't seem to be a good way to deal with version numbers, either, so I'll probably just get rid of that field or try to make it just an editable text field at some point.

I've started using the Trac database, and it's great. A few requests: 1) Can you make it so the default package associated with a bug is empty? Otherwise poor abromfile/drocaml.plt is gonna get a lot of unwanted attention. 2) I thought the sorting of the package list was screwy, but now I can't find anything wrong with it. I may be on crack, I can't be sure. ;) 3) Trac supports some plugins that do language-specific syntax highlighting in the Wiki markup. It would be nice if you could install one of the plugins that recognizes Scheme (and as the maintainer of dherman/java.plt and dherman/javascript.plt, I'd add that Java and JavaScript would be nice too). I know configuring Trac is obnoxious 'cause you end up having to hack into the Python, but it would be really nice. Thanks!

Re: Cleanup on Servlet Timeout (Again)

Henk Boom — 2008-08-28T19:07:36

Simply because this feels like an atomicity problem rather than a synchronization problem. Not really an important reason, but an intuitive one. Except that if it's not atomic I have to make sure that the monitor doesn't attempt to close the transaction while the query is running, so I either need to use the same thread or introduce a new lock. I think using the same thread is the simpler solution. Important question: what is the overhead of blocking on inter-process communication? I'm guessing it's much less than the time it takes to make the database query, so it would be OK to use this every time, but I don't know. Right, thanks. I was planning on checking the status of done-s when handling the fail-s event, but I forgot. Now that I think about it, that would be unintuitive behaviour for fail-s, so I've changed it to set! fail-s to #f after posting done-s so that I know not to post it as well. I'm curious about the behaviour of this, so I'd like to try it out. Wouldn't the same sort of delays happen when trying to send through a channel to the server? (Obviously the same workaround does not work in that case) Henk _________________________________________________ For list-related administrative tasks: http://list.cs.brown.edu/mailman/listinfo/plt-scheme

Re: r6rs timer

Ken Dickey — 2008-08-28T18:18:27

R6RS library compatibility is still a bit in flux, but the basic strategy for importing implementation specific features is to define a *-compat..ss file and have your program import library *-compat. You still need to set the the implementation specific search paths and possibly symbolic links. E.g. see attached process-compat.*.sls files which live in my "kend" directory. Use: (import (kend process-compat) ;; ... ) Close enough?

Re: r6rs timer

Jos Koot — 2008-08-28T18:00:41

Thanks for replying. Much obliged indeed.But as the implementation of SRFI 19 depends on PLT Scheme, I may as well directly import macro "time" from scheme/base. I was looking for a timing tool that is available in all R6RS implementations. Apparently such a timer is not included in R6RS or any of its libraries. An omission?
