Hello I am using GTK+ version 1.2.6 on Solaris(Sparc). So far it was doing good. Recently I have included a header file(say "test.h") to my source code. But when I compile my source , the compiler outputs the following warning. Warning: Invalid white space character in directive My test.h looks like this: #ifndef TEST_H #define TEST_H : ; definitions of some structures : #endif I've noted that if I link my source to another gtk source file which also in cludes "gtk/gtk.h", the same thing happens. It seems there is something wrong with "define" or "ifndef" directives. Any suggestions? Best Regards, Takdir([EMAIL PROTECTED]) -- To unsubscribe: mail -s unsubscribe [EMAIL PROTECTED] < /dev/null
