This bug can be solved by changing the existing as-needed patch
(gammu-1.07.00-as-needed.patch):

It is needed to move the $(LDLIBS) from the beginning of line 18 to its end.


Btw. Deleting -Wall from the Makefiles will decrease output by 1000th of
warning-lines when using gcc-4.1.1.

I'm confused. You say I need to modify line 18 of the as-needed.patch but your
errors are referring to "Linking gammu-shared" command, which is at line 27.
The line 27 cannot be wrong since the only option after the libraries is the -o
outfile (not something that would break linkage with --as-needed).

Btw, I did build it successfully using LDFLAGS=-Wl,-O1,--as-needed and
gcc-3.4.6, so I guess it fails only on gcc-4.1?

I am trying to emerge gammu with these use-flags USE="bluetooth -debug -irda
-mysql"

The error message clearly states that ./common/libGammu.so is linked wrong
(more precise: is not linked with -lbluetooth but using its functions)

But as a library is allowed to have undefined symbols the error occurs when
linking against this lib.

moving the LDLIBS to the end of the line corrects the linking order (the to be
linked object files before the referenced libs).

At least for final linking this order is the only allowed - seems to work the
same way when linking shared objects.

I identified failing makefile command by the "Linking gammu-shared" line on top
of the captured output (please notice the echos above every change made by
as-needed.patch). If the failing make command were the one modified at the line
18 of the patch, it would have been "Linking libGammu.so.0.0", but I reckon you
made a mistake when you copy-pasted the output.

Anyway, I've fixed it in cvs. 
It still builds successfully on my gcc (yes, first I've set the USE flags to
match yours).

That is the thing I mean which makes it complicate.

The lib is linked wrong, but the error does not show here.


It first shows when linking something against the built lib.
