I think this might be possible, but if it meant that not only guile, but every lib and app that was linked against guile would have to be packaged two ways, then it's probably not feasible. > It is not possible to load this plugins with some C++ constructs > (e.g. exceptions, don't know the full list), since guile > crashes. Are we talking about guile functions calling c++ functions, or c++ functions calling guile functions here, and are we talking about the c++ code being accessed via guile loaded (dynamic-link)ed shared libraries or via direct linking/loadinga? Also is there a description of the problem available anywhere? i.e. in the case of exceptions where c code is calling c++ code, is it a problem if the c++ code throws an exception at all, or only if it tries to throw one up to the c level. If the latter, then can the c++ code just be required to have a catch-all "catch" at the top-level in all of the functions guile will be calling? -- Rob Browning rlb @defaultvalue.org, @linuxdevel.com, and @debian.org Previously @cs.utexas.edu GPG=1C58 8B2C FB5E 3F64 EA5C 64AE 78FE E5FE F0CB A0AD _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://mail.gnu.org/mailman/listinfo/guile-devel
