Troubles building an executable

ROOT

Well, my problem is that I couldn’t compile my own application because I got the errors:

Hi,

It seems that you are trying to link code build with gcc 2.95.2 with the version 2.96 of the compiler. Make sure that you always use the same compiler.

Cheers,
Philippe.

Well in fact I had corrected the version of the gcc compiler but the problem presists … I don’t know why …

There’s anybody out there who could help me please?

Hi,

Make sure that you recompile everything from scratch with the correct compiler and linkers. Then, if there is still an error, send me the new error output.

Cheers,
Philippe.

Well I try to do that and what I get is the following:

When I use another makefile named Makefile … i got:

lncms01> make
make: *** No rule to make target Analizav00LinkDef.h', needed byAnalizaGUIv00Dict.cxx’. Stop.

In attachement I will send the files … if you or soemone else could help me I’ll be very greatfull.

Hi,

The problem is that in your header files you have:

const char *filetypes[] = { //"All files", "*", ....
This is the instantiation of a variable. This means that EACH source file that include this header will create a duplicate of this (hence the linker error).
Instead you should have that statement in a source file and just have something like:

in the header file.
Better yet you should not use global variables …

Philippe.
