Thanks for the quick response. I removed ~/.cache/common-lisp, started SBCL and tried to load Drakma. I got this error:* (ql:quickload "drakma")To load "drakma":Load 1 ASDF system:drakma; Loading "drakma"[package trivial-gray-streams]....................[package flexi-streams]...............................................................................................................................[package cffi-utils]..............................[package cffi-features]...........................[package cffi-sys]...debugger invoked on a SB-EXT:PACKAGE-LOCKED-ERROR:Lock on package SB-ALIEN violated when interning SHARED-OBJECT-FILE while inpackage CFFI-SYS.See also:The SBCL Manual, Node "Package Locks"Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.restarts (invokable by number or by possibly-abbreviated name):0: [CONTINUE ] Ignore the package lock.1: [IGNORE-ALL ] Ignore all package locks in the context of this operation.2: [UNLOCK-PACKAGE] Unlock the package.3: [RETRY ] Retrycompiling #<CL-SOURCE-FILE "cffi" "src" "cffi-sbcl">.4: [ACCEPT ] Continue, treatingcompiling #<CL-SOURCE-FILE "cffi" "src" "cffi-sbcl"> ashaving been successful.5: [ABORT ] Give up on "drakma"6: Exit debugger, returning to top level.(SB-EXT:PACKAGE-LOCK-VIOLATION#<PACKAGE "SB-ALIEN">:SYMBOLNIL:FORMAT-CONTROL"interning ~A":FORMAT-ARGUMENTS("SHARED-OBJECT-FILE"))0]Is this a problem with my SBCL installation?Thanks,PatrickOn Mar 23, 2013, at 1:13 PM, Hans Hübner <hans.huebner@gmail.com> wrote:I have just tried this(drakma:HTTP-REQUEST "http://ichart.yahoo.com/table.csv?s=IBM&a=0&b=01&c=2012&d=11&e=31&f=2012&g=d&ignore=.csv")
with Drakma from current Quicklisp and it works. I guess that you have .fasl files of old versions somewhere. Try removing ~/.cache/common-lisp/ and maybe fetch Quicklisp again.-Hans_______________________________________________On Sat, Mar 23, 2013 at 3:03 PM, Patrick May <patrick.may@mac.com> wrote:
I'm trying to get Drakma working with SBCL. I've loaded it with quicklisp but when I try to connect to a website in Slime, I get this error:
The function DRAKMA::WITH-CHARACTER-STREAM-SEMANTICS is undefined.
[Condition of type UNDEFINED-FUNCTION]
Any idea what could be causing this? I've attached the backtrace in case that helps.
Thanks,
