It seems that uSTL 1.4 has introduced a portability issue. Building the
tests for target "m5272c3" (for example):

Are you able to provide a portable implementation of NextPow2() and
submit upstream?

Note also that your patch to include/ustl/uctrstrm.h prevents building
uSTL with "-fno-rtti" and should be omitted.

I'm copying Uwe Kindler to ensure he's aware of your contribution.

Hi John

Sorry, that was pretty bad testing on my side ;) only did some tests on 
the synth target. The shortcomings are pretty obvious!

I'll fix the mistakes and post an updated patch.

Here is the updated patch.

Added a generic implementation for the NextPow2, which is currently 
suboptimal but mimics what the x86 implementation is doing. Also removed 
the introduced change in include/ustl/uctrstrm.h so it should build 
again with -fno-rtti.

Hi Simon
and John,

I built successfully uSTL tests using the Simon's latest patch for
arm7tdmi, i386 pc (i386-elf-gcc from eCosCentric) targets.

But, when I tried to build it for i386linux target I got the same error
likes John got.

Simon, I often run update-manager :-( and my stuff is

It seems for me we have to try something is suggested here (for example)
http://lists.busybox.net/pipermail/uclibc-cvs/2005-December/007852.html

Though I did not grep much the NET for the issue...

I will try to investigate in the issue tonight.

Hi

I could not understand why a build with native GCC wanted 'lrint'
http://www.opengroup.org/onlinepubs/009695399/functions/lrint.html

I tried a hack (added libm.a to linker GROUP), and that helped...

$ sed -i 's,libgcc_eh.a,& libm.a,' install/lib/target.ld

$ grep GROUP install/lib/target.ld
GROUP(libtarget.a libgcc.a libsupc++.a libgcc_eh.a libm.a)

Well, this was brutal hack, but it was possible to build all tests on my
Linux box. Should we implement 'lrint' in eCos libm?

Re: uSTL 1.4 update

[Sergei Gavrikov]

Hi

Now I see that is not uSTL *1.4* issue. I tried to build 'bvt23' using a
prepatched version of uSTL (1.3) for synthetic target and I got that
stop too!

IMO, the linking error on sythetic cannot stop the uSTL updating. May be
we have to register the linking issue on Bugzilla instead?

John, can you confirm the linking issue with uSTL 1.3 for synthetic in
your Linux environment?

Now checked in. Thank you for the contribution.

I recommend that you submit your portable NextPow2 implementation to
Mike Sharov as a patch for inclusion in the uSTL master repository.
