Hello, I get a nasty segmentation fault as soon as a SQLconnect fails using unixodbc, e.g. the isql coming with! The ddd output is quoted below.
Let me tell you how I build the Drivers etc., maybe the error is related to this. I used gcc version 2.95.3 20010315 (SuSE), to compile: unixODBC-2.2.2.tar.gz from www.unixodbc.com MyODBC-3.51.03.tar.gz from www.mysql.com !!!! HOWEVER, when building the driver from MyODBC 3.51.02 which came with unixodbc, this seg fault doesn't occur !!!! The server in binary distribution mysql-3.23.52-pc-linux-gnu-i686.tar.gz und the shared lib and devel and stuff MySQL-shared-3.23.52-1.i386.rpm MySQL-devel-3.23.52-1.i386.rpm Here, I am wondering, whether these have been build for thread-safe-clients, as this has been required somewhere. I tried to follow the build instruction in INSTALL best I could, for unixODBC and especially for MyODBC, I didn't rebuild the mySQL binaries, and the shared client libs, though. So, ddd gives to following output, where ===>>> indicates the SEGFAULT in error.c SQLRETURN SQL_API SQLError(SQLHENV henv, SQLHDBC hdbc, SQLHSTMT hstmt, SQLCHAR FAR *szSqlState, SQLINTEGER FAR *pfNativeError, SQLCHAR FAR *szErrorMsg, SQLSMALLINT cbErrorMsgMax, SQLSMALLINT FAR *pcbErrorMsg) { SQLRETURN error=SQL_INVALID_HANDLE; DBUG_ENTER("SQLError"); if (hstmt){ error = my_SQLGetDiagRec(SQL_HANDLE_STMT,hstmt,1,szSqlState, pfNativeError, szErrorMsg, cbErrorMsgMax,pcbErrorMsg); if(error == SQL_SUCCESS) CLEAR_STMT_ERROR(((STMT FAR*)hstmt)); } else if (hdbc){ error = my_SQLGetDiagRec(SQL_HANDLE_DBC,hdbc,1,szSqlState, pfNativeError, szErrorMsg, cbErrorMsgMax,pcbErrorMsg); if(error == SQL_SUCCESS) CLEAR_STMT_ERROR(((STMT FAR*)hstmt)); } else if (henv){ error = my_SQLGetDiagRec(SQL_HANDLE_ENV,henv,1,szSqlState, pfNativeError, szErrorMsg, cbErrorMsgMax,pcbErrorMsg); if(error == SQL_SUCCESS) ===>>> CLEAR_STMT_ERROR(((STMT FAR*)hstmt)); } DBUG_RETURN(error); } Program received signal SIGSEGV, Segmentation fault.
