Making simple QTE application, cannot find libpthread_nonshared.a

Making simple QTE application, cannot find libpthread_nonshared.a

[Dmitry Vinokurov]

Hello,

Example from manual chapter"Creating and Using a Qt Embedded SDK" fails 
at linking stage:
---------------------------
$ qmake2
$ make

---------------------------

Could anybody suggest, how this issue can be solved? I even have no 
idea, why it searches for static library instead of dynamic.

Thanks.

When did you build meta-toolchain-qte?

Yesterday pulled from dev branch (git describe output is 
pre-nov2009-core-updates-606-g237cbb4) and made meta-toolchain-qte 
rebuild, then tried again to build example -- same error "cannot find 
/usr/lib/libpthread_nonshared.a inside 
/usr/local/minimal/arm/arm-oe-linux-gnueabi"

Could you look into the libc-dev package, or in general libc packages to see 
if this library is present in any package? You could use mc or 
Packages.filelist to figure that out.

Oh you are using minimal? So all these files are installed into /lib? So you 
actually do have a libpthread_nonshared.a but it is in lib/ and not usr/lib? 
Could you confirm this?

I think you're thinking of micro, not minimal.  AFAIK, minimal uses the
"normal" filesystem layout, complete with /usr.

Yeah... confusion on my side... I know that DISTRO=micro is broken for gcc 
targets (on the device, on the SDK).

Here is search results:
--------
[14:50]raydan@t46x[build]$ find tmp | grep libpthread_nonshared.a
tmp/staging/armv5te-oe-linux-gnueabi/usr/lib/libpthread_nonshared.a
tmp/work/armv5te-oe-linux-gnueabi/eglibc-2.10-r7.5/staging-pkg/staging/armv5te-oe-linux-gnueabi/usr/lib/libpthread_nonshared.a
tmp/work/armv5te-oe-linux-gnueabi/eglibc-2.10-r7.5/image/usr/lib/libpthread_nonshared.a
tmp/work/armv5te-oe-linux-gnueabi/eglibc-2.10-r7.5/package/usr/lib/libpthread_nonshared.a
tmp/work/armv5te-oe-linux-gnueabi/eglibc-2.10-r7.5/build-arm-oe-linux-gnueabi/nptl/libpthread_nonshared.a
--------
[10:43]raydan@t46x[qte-example]$ find /usr/local/minimal/ | grep 
libpthread_nonshared.a
--------

So, libpthread_nonshared.a exist in eglibc for ARM, but not present in 
the QtE SDK.

How do you think, is there better way to solve this issue than just 
copying library into QtE SDK lib dir?

Copied libpthread_nonshared.a from eglibc dir to 
/usr/local/minimal/arm/arm-oe-linux-gnueabi/usr/lib. Tried 'make' -- 
similar trouble with libc_nonshared.a. Copied it too, 'make' succeed, 
binary ready. For the present I can't test it on the board, hope I'll do 
it at this week.

Maybe this two libraries should be copied from libc to QtE SDK during 
it's build?

ah eglibc... so your finding is that this library is not in any glibc-* 
package? So when building glibc you must get a warning like unpackaged 
content...   could you take a look at the log?

In high level terms. The library should be in a package (like -dev) and it 
should be installed. If that is not the case it must be fixed.


thanks

Following commands show no output (though log files exist there):
--------
grep -i unpackaged tmp/work/armv5te-oe-linux-gnueabi/eglibc-2.10-r7.5/temp/*
grep -i "not shipped" 
tmp/work/armv5te-oe-linux-gnueabi/eglibc-2.10-r7.5/temp/*
--------

"When building glibc" -- you meant eglibc? glibc wasn't build at all.
