Ok, English is not my native language, and I even

Neither is it for me, though I had some English

However, I assume everybody to understand the

computer problems :).

Maybe. But I see conflict in using
previous/non-grace result from dlerror(), which
I think grace should not do.
Indeed, so the proper way is to call dlerror()
prior to a dlsym() call, to reset any previous
error condition. Something like this:
/* clear error condition */
dlerror();
/* use dlsym and check for error */
data = dlsym();
if ( (error = dlerror()) != NULL ) {
errmsg(error);
return FAILURE;
}

OK, great.
Meanwhile, I came closer to the real problem.
You don't need to create the link in /usr/X11R6/lib.
The problem is dlerror(). Whenever one of the
dl-functions is called, it will set the error
indicator in dlerror() in case of problems.
For some unclear reason, the error indicator in
dlerror is set when grace starts-up. I don't
know why yet (I'll discuss that with the grace
mailing list).
When grace uses the dl-functions in src/dlmodule.c,
which is caused by the USE... lines in
gracerc.user, something like this happens:
dlopen(library name, MODE);
if (dlerror() != NULL) {
report_error();
exit(1);
}
Now, dlerror() is set, but not by dlopen(), but
by some other part at start-up. A workaround is
following:
/* reset any possible earlier error */
dlerror();
dlopen(library name, MODE);
if (dlerror() != NULL) {
report_error();
exit(1);
}
When I patch grace with this dummy dlerror(),
prior to the dl-function calls, all works like
a charm (and you don't need the link in
/usr/X11R6/lib anymore).
As I said before, I now have to find out why
grace activates the dlerror() at start-up.
Regards,
Rob.

As I said before, I now have to find out why grace activates the dlerror() at start-up. So, problem is on grace side, not on FreeBSD side. I think there are some differences in execution environment for grace on Linux and FreeBSD. Then we have to tell the grace developper, who is a devote Linux user, about the oddities on FreeBSD, or we have to come up with a reasonable patch to make it work properly on FreeBSD. Meanwhile I digged a little deeper in the grace source code, to find out at what place exactly the dlerror() error-indicator is set. When grace initializes its GUI, there is this kind of code: --- XtAppContext app_con; Display *disp = NULL; char *display_name = NULL; XtSetLanguageProc(NULL, NULL, NULL); XtToolkitInitialize(); app_con = XtCreateApplicationContext(); disp = XOpenDisplay(display_name); --- (I have simplified this code snippet a bit, for this example; also, grace uses Motif for its GUI). Before the XOpenDisplay() call, dlerror() does not have the error-indicator set, but after that call, it has. Is this where Linux and FreeBSD are out-of-sync? Or does Grace something wrong here, or is this a problem cause by FreeBSD or Xorg? I feel I'm getting closer and closer, but still I have not really a good idea of what's going on here!

I think, that when XOpenDisplay called, ld.so tries load some libraries
from preconfigured paths, and
last unsuccessful attempt is recorded for dlerror().
dlopen() _does not_ reset dlerror() state on sucess, it just returns non
NULL. So you must not check dlerror() for error condition, you need
check return result of dlopen(), and if it is NULL, then you need use
dlerror().
So, code in grace:
dlopen(library name, MODE);
if (dlerror() != NULL) {
report_error();
exit(1);
}
need to be:
handle = dlopen(library name, MODE);
if (handle == NULL) {
report_error(dlerror());
exit(1);
}
just because dlerror() != NULL is not indicator of error.

Sorry,
I have reread manual page for dlerror() and found that it need clear
error state after call, but
dlerror() in src/libc/gen/dlfcn.c does not do this:
#pragma weak dlerror
const char *
dlerror(void)
{
return sorry;
}
So error is in FreeBSD libc, if I understand this correctly. I'll do PR.

Bad day for me :-(.
Above code is from src/libc/gen/dlfcn.c, but real dlerror for dynamicaly
linked executables is in rtdl.c, and it works as described in manual
page (clears error status).
So problem is somewhere else. Sorry for false info.

Talk to the xorg maintainers ([EMAIL PROTECTED]). I suspect there are two problems: the libXcursor.so.1.0.2 reference in the x library, which should not be there, and a bug in xmgrace for not correctly handling dlerror(), as Igor has been explaining. xmgrace should be robust enough to handle the case of some other application having failed to dlopen() something, instead of assuming it has perfect knowledge of the program state.

(I have simplified this code snippet a bit, for
this example; also, grace uses Motif for its GUI).
Before the XOpenDisplay() call, dlerror() does
not have the error-indicator set, but after
that call, it has.
I wrote simple program to test XOpenDisplay +
dlopen:
#include X11/Xlib.h
#include dlfcn.h
#include stdio.h
main(int argc, char **argv)
{
Display *d;
void *handle;
void *f;
char *err;
if ((err=dlerror()) != NULL) {
fprintf(stderr,dlerror: %s\n,
err);
exit(1);
}
d = XOpenDisplay(NULL);
if (d == NULL) {
fprintf(stderr, Error in
XOpenDisplay\n);
exit(1);
}
if ((err=dlerror()) != NULL) {
fprintf(stderr, dlerror: %s\n,
err);
exit(1);
}
XCloseDisplay(d);
handle = dlopen(argv[1], RTLD_NOW);
if (handle == NULL) {
fprintf(stderr, dlopen: %s\n,
dlerror());
exit(1);
}
f = dlsym(handle, argv[2]);
if (f == NULL) {
fprintf(stderr, dlsym: %s\n,
dlerror());
exit(1);
}
dlclose(handle);
}
Compile it with
gcc -o t t.c -I /usr/X11R6/include -L /usr/X11R6/lib
-lX11
Then test with:
./t /usr/lib/libm.so pow
Then
./t /usr/lib/libm.so pow33
dlsym: Undefined symbol pow33
So as you can see on my system all looks good. Try
it on your system.
First:
NULL return from dlsym() does not always imply an
error. dlsym() can return NULL because it has an
empty list, but this does not set the error
indicator of dlerror(), because it is not an error.
However, if an error occurs, dlsym() has NULL as
a return (that's probably most sensible return).
Second:
I get different output than you, from this part
of the program:
d = XOpenDisplay(NULL);
if (d == NULL) {
fprintf(stderr, Error in XOpenDisplay\n);
exit(1);
}
if ((err=(char *)dlerror()) != NULL) {
fprintf(stderr, dlerror: %s\n, err);
exit(1);
}
I get here:
dlerror: Shared object nss_dns.so.1 not found,
required by t
So apparently dlerror() is set by XOpenDisplay().
Hmmmyesterday I updated my world and kernel
to most recent 5-Stable, and after that I
recompiled all my ports. Still get this problem!
This is my /etc/make.conf:
---

Does that cause any problems?

I have rebuilt xmgrace/grace from sources without port Makefile, and all works fine. Be sure that you do NOT start xmgrace, while there is a gracerc.user in the 'pwd' (current directory); because that prevents the loading of ~/.grace/gracerc.user , which then may give you the impression that all is OK. For me, I still get the same error, even without the port's Makefile. Rob. __ Yahoo!

math/grace port: libXcursor.so.1.0 not found ??
Hi, I'm running FreeBSD 5-Stable. I only seem to encounter this problem with the math/graphical port 'grace', and the dlopen() call inthere. It seems to be a FreeBSD specific problem and I wonder if other people on this list encounter the same problem. This is the problem: 1. Install Grace from ports (math/grace) 2. Create $HOME/.grace/gracerc.user and put one line in this file: USE pow TYPE f_of_dd FROM /usr/lib/libm.so (this is the example from the Grace UsersGuide) 3. Start grace like this: $ xmgrace Shared object libXcursor.so.1.0 not found, required by xmgrace DL module load failed: USE pow TYPE F_OF_DD FROM /usr/lib/libm.so Error at line 1 Because if this library problem, Grace cannot load pow from /usr/lib/libm.so. However, apart from that, grace starts normally. The syntax in file gracerc.user is correct; I have verified this with the Grace mailinglist. The line Shared object...not found is the error message-string set by the dlopen() call in Grace: handle = (void *)dlopen(/usr/lib/libm.so, RTLD_LAZY) When I do a 'locate libXcursor.so.1.0', I get: /usr/compat/linux/usr/X11R6/lib/libXcursor.so.1.0.2 Why is dlopen() failing on libXcursor.so.1.0 ? A possible hint could be that libXcursor.so.1.0.2 appears when 'strings /usr/X11R6/lib/libX11.so.6'. Why is it in libX11.so.6 ?? Thanks for help or clues! Rob. __ Yahoo!
