Hi everybody. First, sorry for my english, i am argentinian. I am trying to use a c library called openDBX that helps us talk to different RDBMS. Here is the link: http://www.linuxnetworks.de/doc/index.php/OpenDBX I have already compiled and installed. Now, i am trying a simple c programe that uses it. The problem is that when i tried to compile this program, i have en compile error in a header i need to include of openDBX. Mi c program (Prueba.c) is this: Code: #include <stdio.h> #include <stdlib.h> #include <odbx.h> int main(void) { puts("Hello World!!"); return EXIT_SUCCESS; } The file odbx is the one i need to use. See that the problems occurs during compilation, even if i don't use it. This file (odbx.h) is in /usr/local/include. I undestand that this directory is standard so i don't need to pass any parametres to gcc. don't i ? The error is this: In file included from Prueba.c:3: /usr/local/include/odbx.h:206: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘odbx_rows_affected’ If i open de odbx, the line 206 is like this: uint64_t odbx_rows_affected( odbx_result_t* result ); The uint64_t is only used there. I think there is the problem. I see that odbx.h includes the stdint, in this way: #ifdef HAVE_STDINT_H #include <stdint.h> Can i have a problem with this and the gcc ??? do you need some other information so that to help me ? I am using gcc version 4.1.3 and ubuntu gutsy gibbon. very thanks mariano
