This appears to be a bug in the app. It is attempting to use dlerror to check if the previous dlsym() call failed, rather than checking if the dlsym returned NULL. libX11 is doing just fine, but a side effect of its eventually-successful dlopen()ing of libXcursor is that it will have caused a dlopen error, so dlerror() will be returning non-NULL for the next person that comes along. Attached is an untested patch. --=20 Eric Anholt eta@lclark.edu http://people.freebsd.org/~anholt/ anholt@FreeBSD.org --=-VL+vv1xsgFU/N+/4df+o Content-Disposition: attachment; filename=grace-dlerror.diff Content-Type: text/x-patch; name=grace-dlerror.diff; charset=ISO-8859-1 Content-Transfer-Encoding: base64 SW5kZXg6IE1ha2VmaWxlDQo9PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PT09DQpSQ1MgZmlsZTogL2hvbWUvbmN2cy9wb3J0cy9t YXRoL2dyYWNlL01ha2VmaWxlLHYNCnJldHJpZXZpbmcgcmV2aXNpb24gMS40NA0KZGlmZiAtdSAt cjEuNDQgTWFrZWZpbGUNCi0tLSBNYWtlZmlsZQkxIE1hciAyMDA1IDE0OjQxOjQyIC0wMDAwCTEu NDQNCisrKyBNYWtlZmlsZQkyOCBPY3QgMjAwNSAwNzo0Njo1MyAtMDAwMA0KQEAgLTcsNyArNyw3 IEBADQogDQogUE9SVE5BTUU9CWdyYWNlDQogUE9SVFZFUlNJT049CTUuMS4xOA0KLVBPUlRSRVZJ U0lPTj0JMA0KK1BPUlRSRVZJU0lPTj0JMQ0KIENBVEVHT1JJRVM9CW1hdGggcHJpbnQNCiAjDQog TUFTVEVSX1NJVEVTPQlmdHA6Ly9wbGFzbWEtZ2F0ZS53ZWl6bWFubi5hYy5pbC9wdWIvZ3JhY2Uv c3JjL3N0YWJsZS8gXA0KSW5kZXg6IGZpbGVzL3BhdGNoLWRsbW9kdWxlLmMNCj09PT09PT09PT09 PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT09PT0N ClJDUyBmaWxlOiBmaWxlcy9wYXRjaC1kbG1vZHVsZS5jDQpkaWZmIC1OIGZpbGVzL3BhdGNoLWRs bW9kdWxlLmMNCi0tLSAvZGV2L251bGwJMSBKYW4gMTk3MCAwMDowMDowMCAtMDAwMA0KKysrIGZp bGVzL3BhdGNoLWRsbW9kdWxlLmMJMjggT2N0IDIwMDUgMDc6NDg6MzYgLTAwMDANCkBAIC0wLDAg KzEsMTMgQEANCistLS0gc3JjL2RsbW9kdWxlLmMub3JpZwlTYXQgSnVsICAzIDEzOjQ3OjQ1IDIw MDQNCisrKysgc3JjL2RsbW9kdWxlLmMJRnJpIE9jdCAyOCAwMDo0NzozMyAyMDA1DQorQEAgLTkw LDggKzkwLDggQEANCisgICAgIH0NCisgICAgIA0KKyAgICAgbmV3a2V5LmRhdGEgPSBkbHN5bSho YW5kbGUsIGRsX2Z1bmN0aW9uKTsNCistICAgIGlmICgoZXJyb3IgPSAoY2hhciAqKSBkbGVycm9y KCkpICE9IE5VTEwpIHsNCistICAgICAgICBlcnJtc2coZXJyb3IpOw0KKysgICAgaWYgKG5ld2tl eS5kYXRhID09IE5VTEwpIHsNCisrICAgICAgICBlcnJtc2coKGNoYXIgKikgZGxlcnJvcigpKTsN CisgICAgICAgICBkbGNsb3NlKGhhbmRsZSk7DQorICAgICAgICAgcmV0dXJuIFJFVFVSTl9GQUlM VVJFOw0KKyAgICAgfQ0K --=-VL+vv1xsgFU/N+/4df+o-- --=-HWYSL+X/Ewab77w0VMdu Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (FreeBSD) iD8DBQBDYdgrHUdvYGzw6vcRAnlNAJ97SKWIyan4Xd1hn4JTuuTeqkpvoACfTEQU I4/77cEVj17KeOIyz8cdODU= =rPL9 -----END PGP SIGNATURE----- --=-HWYSL+X/Ewab77w0VMdu--
