[sword-devel] Is --enable-debug what I want?

[Dmitrijs Ledkovs]

I wanted to create a Debian package with debug symbols in it.

I've setup packaging and I've also added --enable-debug flag to
configure. It failed to build from source on all 4 ubuntu releases X 3
arch with following error:

libtool: compile:  g++ -DHAVE_CONFIG_H -I. -I../include -I../include
-I/usr/include -DUSE_AUTOTOOLS -DUNIX -Dunix -D__unix__

without the --enable-debug flag it builds fine (relative part I think is):

libtool: compile:  g++ -DHAVE_CONFIG_H -I. -I../include -I../include
-I/usr/include -DUSE_AUTOTOOLS -DUNIX -Dunix -D__unix__

Is it known that --enable-debug is broken? Do I need it if I want
debug symbols left within binaries?

What does it actually do?
