Re: [Ecls-list] threading failures

Hello, that's probably my fault, sorry. I've migrated bugs manually and probably missed this one (I remember this bug! but can't find anywhere). I'm adding it to regression tests in repository, thanks! Yes, old reports are unfortunately lost. As a sienote, please use ecl-devel(a)common-lisp.net mailing list – I'm closing the old one today. You can subscribe here https://mailman.common-lisp.net/listinfo/ecl-devel . All archives before 2015-08-10 are imported to the new one and gmane stream is redirected (if you use it).

Displaying lisp errors while running with save_eval
by Diogo Franco 08 Dec '15

08 Dec '15

Hi all, Uncaught error conditions in lisp code don't display in *standard-output* for me, when ecl is running embedded in c (i presume the reason is that i'm calling the lisp functions using save_eval()). My workflow on the shell while developing is then to do ctrl-c which drops me to the REPL, and to manually execute the functions, which will print the error. I'm no expert on the inner workings of ecl, so forgive me if this is a dumb question, but is there some way to get the errors in *standard-output* even when using save_eval()? Thanks in advance, Diogo Franco
