Hi, ---------------------------------------------------------------------------------------------------------------------------------------------- #include<stdio.h> typedef struct { int x; int y; }type27; int a; int main() { int m,n; type27 t; a=100; printf("\n %d %d %d ",t.x,t.y,(t.x)+(t.y)+a); } ---------------------------------------------------------------------------------------------------------------------------------------------- I compiled the above program as armv5tel-redhat-linux-gnueabi-gcc myprogram.c -g When I print the dwarf information with readelf --debug-dump a.out I got the following debugging information about the typedef "type27" : <1><147>: Abbrev Number: 6 (DW_TAG_typedef) <148> DW_AT_name : type27 <14f> DW_AT_decl_file : 1 <150> DW_AT_decl_line : 6 <151> DW_AT_type : <126> But when I compiled the same(myprogram.c) as armv5tel-redhat-linux-gnueabi-g++ myprogram.c -g I could not get any debugging information for "type27" Why so???? In this link http://examples.oreilly.com/palmprog/CDROM/Linux/gcc/gcc-2.7.2.2/README.DWARF I foundout the following statements: "DWARF generation for the GNU g++ compiler is still not operable. This is due primarily to the many remaining cases where the g++ front end does not conform to the conventions used in the GNU C front end for representing various kinds of declarations in the TREE data structure. It is not clear at this time how these problems will be addressed." Is my problem is because of "g++ front end does not conform to the conventions used in the GNU C front end for representing various kinds of declarations in the TREE data structure"???? If so can anyone tell me what are these g++ front end issues?? and why are these causing problems?? Thanks in advance.
