I was able to execute the following on my original platform (Solaris 8) (loop :repeat 100 :do (break-cl-ppcre::test-telnet-argsmmgts5--case-2 "localhost" :prompt break-cl-ppcre::+default-mgts-server-prompt--break-cl-ppcre+)) with no problems. Looks like it did the trick.

[cl-ppcre-devel] Startup issues [fixed]
by Randall Randall 19 Apr '04

19 Apr '04

Hi, all. So, Jim Prewett pointed out offlist that this certainly should not be happening if I use a saved core. The reason it was still happening with a saved core was that I still had that (load ...) line in the .cmucl-init.lisp file. With that removed, using the .core I saved, it doesn't do the long compilation on startup. I'm still curious as to why it was doing it at all, but at least it's not tapping me on the shoulder whenever I start up my lisp now. :) Thanks, Jim! -- Randall Randall <randall(a)randallsquared.com> 'I say we put up a huge sign next to the Sun that says "You must be at least this big (insert huge red line) to ride this ride".' -- tghdrdeath(a)hotmail.com

[cl-ppcre-devel] (no subject)
by Randall Randall 19 Apr '04

19 Apr '04

Hi, I'm new to lisp and new to cl-ppcre. After building cl-ppcre, every time I start lisp, even if I don't explicitly load cl-ppcre.ppcf, I get ~150 lines of: ; Compiling LAMBDA (PCL::.PV-CELL. PCL::.NEXT-METHOD-CALL. CONDITIONS::X): ; Compiling Top-Level Form: before a lisp prompt. Is this usual? Of course, in production it won't matter, since I'll only very occasionally be restarting, but it's surprising and I wonder if it might be indicative of an actual problem with the build or install or something? Thanks! -- Randall Randall <randall(a)randallsquared.com> 'I say we put up a huge sign next to the Sun that says "You must be at least this big (insert huge red line) to ride this ride".' -- tghdrdeath(a)hotmail.com
