Grondona <[email protected]> Date: Tue, Sep 28, 2010 at 12:05 PM Subject: Re: p...@cluster5: Error loading self: file not found] To: Ronald Kasl <[email protected]> Cc: [email protected] This appears to be a debian bug. You will need to have the libgenders0-dev package installed to have an operational genders module with pdsh-2.18-7. (Actually this is kind of an upstream bug too). Currently the upstream pdsh does a dlopen of self to query for the 'genders_query' symbol, and does a fallback to genders_getnodes() if this symbol does not exist. Unfortunately, the debian version of pdsh for some reason always fails when calling lt_dlopen (NULL) so I suggested that they instead dlopen the libgenders.so library directly. Unfortunately, libgenders.so is not installed on your system (it is actually a soft link), unless you have libgenders0-dev installed, thus you get the "error opening self" error message (the error wasn't updated with the new debian fix) I think that the version of genders in debian does have the genders_query() function, so the runtime test for it is not necessary. I would actually suggest that the use of dlopen/dlsym in genders.c should just go away in the debian version. I'll do the same upstream, as all modern versions of libgenders have this symbol, so we'll just deprecate backwards compatibility. something like this: diff --git a/src/modules/genders.c b/src/modules/genders.c index 59f40e2..4c1d45b 100644 --- a/src/modules/genders.c +++ b/src/modules/genders.c @@ -37,7 +37,6 @@ #include "src/common/err.h" #include "src/common/xmalloc.h" #include "src/common/split.h" -#include "src/pdsh/ltdl.h" #include "src/pdsh/mod.h" #include "src/pdsh/rcmd.h" @@ -76,10 +75,6 @@ static char *gfile = NULL; static List attrlist = NULL; static List excllist = NULL; -static lt_dlhandle dlh = NULL; -static lt_ptr g_query_addr = NULL; -typedef int (*g_query)(genders_t, char **, int, char *); - /* * Export pdsh module operations structure */ @@ -197,11 +192,6 @@ genders_process_opt(opt_t *pdsh_opts, int opt, char *arg) static int genders_init(void) { - if (!(dlh = lt_dlopen("libgenders.so"))) - errx("%p: Error loading self: %s\n", lt_dlerror()); - - g_query_addr = lt_dlsym(dlh, "genders_query"); - return 0; } @@ -217,7 +207,6 @@ genders_fini(void) if ((gh != NULL) && (genders_handle_destroy(gh) < 0)) errx("%p: Error destroying genders handle: %s\n", genders_errormsg(gh)); - lt_dlclose(dlh); return 0; } @@ -408,29 +397,6 @@ static genders_t _handle_create() return gh; } -/* - * Search attr argument for an '=' char indicating an - * attr=value pair.
