First I was running 6.3 but I upgraded to 7.0 thinking that it might of solve the problem but it didn't. What amazes me is, I've got ubuntu installed on the same machine and it only takes 3 seconds to start, also it only takes 3 seconds to start in windows. Evolution running like this is completely worthless. Any ideas what might be causing this?

As far I'm concerned evolution is out of my list of programs, I still have my doubts about the real reason as to why it takes so long to open. In reality there's no real reason as to why a program will take so long to open, if that's the case evolution will loose a lot of users in the FreeBSD community. > > You're free to build Evolution and e-d-s with debugging symbols, and > watch it load in gdb if you don't believe me.

This patch for this evolution bug was posted in questions by lenzi and it solved that bug, I just thought you would like to know. It's not an evolution bug but glib20 instead. ---------------------------------x------------------------------ The problem is that glib on function g_module_load, searchs for a symbol g_module_check_init, g_module_unload... by default. It occurs that the evolution code, that will be loaded, does not have those functions available... so th glib (and dlsym) tries to find the symbol in every load module in memory... and doing so consumes all cpu for several seconds, for each load module.... ! coded a solution for gmodule that tests for those special symbos, and if found, uses dlsymb(RTLD_NEXT,....) instead of dlsym(handler....) so it will search a much less modules, and evolution will start in 3 seconds... (20 times less...) Of course the correct strategy is to correct code evolution module (libevolution-mail.so). will do next time.... modified file: /usr/ports/devel/glib20/files/patch-gmodule::gmodule-dl.c please note this is only a temporary fix... the correct solution is to fix the evolution module.... ============================================= --- gmodule/gmodule-dl.c.orig 2008-02-07 03:24:53.000000000 -0200 +++ gmodule/gmodule-dl.c 2008-03-11 18:53:44.000000000 -0300 @@ -73,6 +73,14 @@ #endif /* RTLD_GLOBAL */ +static char *special_names[]={ + "g_module_check_init", + "g_module_unload", + "e_plugin_lib_enable", + NULL +}; + + /* --- functions --- */ static gchar* fetch_dlerror (gboolean replace_null) @@ -106,6 +114,7 @@ static gpointer _g_module_self (void) { +#ifndef __FreeBSD__ gpointer handle; /* to query symbols from the program itself, special link options @@ -117,6 +126,9 @@ g_module_set_error (fetch_dlerror (TRUE)); return handle; +#else + return RTLD_DEFAULT; +#endif } static void @@ -141,9 +153,19 @@ { gpointer p; gchar *msg; + char **pn; fetch_dlerror (FALSE); - p = dlsym (handle, symbol_name); + + for (pn=special_names;*pn;pn++) { + if (!strcmp(*pn,symbol_name)) { + p=dlsym(RTLD_NEXT,symbol_name); + break; + } + } + + if (! *pn) + p = dlsym (handle, symbol_name); msg = fetch_dlerror (FALSE); if (msg) g_module_set_error (msg);
