Hello, I am trying to port code from a Debian distribution with gcc version 3.4.4 to a Ubuntu distribution with gcc version 4.1.2. The code compiles and runs on the Debian machine but fails to compile on the Ubuntu with an error message I do not understand. Here is the output of the compile: rjslom@turbo-dog:~/msg$ make gcc msg_client.c -o msg_client In file included from msg_client.c:13: msg_bmk.h:34: error: expected declaration specifiers or '...' before 'msgbmk' msg_bmk.h:34: error: expected declaration specifiers or '...' before 'msqid' msg_bmk.h:34: error: expected declaration specifiers or '...' before 'MSG_TRIALS' msg_bmk.h:34: warning: data definition has no type or storage class make: *** [msg_client] Error 1 The code in question (line 34 of msg_bmk) is a preprocessor macro which is supposed to expand to a user stub for a new system call. Here is the line: _syscall2( int, msgbmk, int, msqid, int, MSG_TRIALS ) The file msg_bmk.h includes the header file <linux/unistd.h> which contains the macro definition. Any feedback would be great. Thanks for you time, Ryan
