Description David Binderman 2005-02-23 06:42:28 EST

Description of problem:

I just tried to compile package conglomerate-0.9.0-1 from 
Redhat Fedora Extras development tree.

The compiler said

cong-error-file-save.c(162): remark #592: variable "volume_capacity"
is used before its value is set

The source code is

	char* volume_capacity_string =
gnome_vfs_format_file_size_for_display(volume_capacity);

Suggest initialise volume_capacity before first use.

Comment 1 Phillip Compton 2005-02-24 14:22:02 EST

WFM, no error on FC3.

Can you provide some additional information:
which release of Fedora are you using?
are you using any kind of build system?
is there anything custom about your system (not core + extras)?

Comment 2 Michael Schwendt 2005-02-24 15:36:05 EST

He's looking for compiler warnings, probably adding -Wall to rpm
optflags and rebuilding all of Extras.

This one is not a bug. Rationale given in lines 152-159.

Comment 3 David Binderman 2005-02-25 04:38:16 EST

>are you using any kind of build system?

The clue is in the remark message - I hope you can recognise
that it isn't a message produced by the GNU C compiler.

In fact, I am using the most excellent Intel C compiler
- better messages (see above) and better code generation.

For conglomerate, this does appear to be code that is
"work in progress" - plenty of commented out bits.
