            Bug ID: 8651
           Summary: libMonoPosixHelper.so wrong link reference in
                    buildroot image
           Product: buildroot
           Version: 2015.11
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned at buildroot.uclibc.org
          Reporter: Markus.Egle at Qiagen.com
                CC: buildroot at uclibc.org
  Target Milestone: ---

With the current buildroot 2015.11.1 (initially seen with 2015.05) configured
to use mono, the libMonoPosixHelper.so will be searched in the
/home/userX/buildroot/output/host/usr/lib/ path. This path and file may exist
on my building machine, but not on the target.

I have a working workaround with creating this folder and copy
libMonoPosixHelper.so from /usr/lib at startup in the ram disk.

Dear Markus Egle,

It is probably reletad to this bug:

https://bugzilla.xamarin.com/show_bug.cgi?id=24131

Try that workaround and report your results here. I'll look at this ASAP.

Till now I'm not really familiar with the config/make procedure. 
So I don't know if I have to change the Makefile.in or the config.in or both. 

Found four possible locations to make the testing changes. 


...> find /home/eglem/buildroot -name "*.in"|grep mono|awk '{print "grep -Hn
libMonoPosixHelper " $1}'|sh|grep target

/home/eglem/buildroot/output/build/host-mono-4.0.2.5/runtime/Makefile.in:629:  
sed
's,target="$(prefix)/$(reloc_libdir)/libMonoPosixHelper$(libsuffix)",target="'$$d'/libMonoPosixHelper.la",'
../data/config > $@t
/home/eglem/buildroot/output/build/host-mono-4.0.2.5/data/config.in:13: <dllmap
dll="MonoPosixHelper"
target="@prefix@/@reloc_libdir@/libMonoPosixHelper@libsuffix@" os="!windows" />
/home/eglem/buildroot/output/build/mono-4.0.2.5/runtime/Makefile.in:629:       
sed
's,target="$(prefix)/$(reloc_libdir)/libMonoPosixHelper$(libsuffix)",target="'$$d'/libMonoPosixHelper.la",'
../data/config > $@t
/home/eglem/buildroot/output/build/mono-4.0.2.5/data/config.in:13:      <dllmap
dll="MonoPosixHelper"
target="@prefix@/@reloc_libdir@/libMonoPosixHelper@libsuffix@" os="!windows" />



Then I just remove the prefix?

Dear Markus Egle,

Could you try to have a look at file /etc/mono/config in your generated image?

You should reply in the bug tracker. I am not sure Markus is a
subscriber of the Buildroot mailing list, and I'm not sure sending
e-mails to bugzilla at busybox.net works.

Otherwise, thanks a lot for taking care of this Mono bug report. It is
good to see additional users testing this functionality, as it will
test it in different conditions.

Thanks!

Thomas

The config file on the target shows this wrong path to the lib. 

grep home /etc/mono/config
        <dllmap dll="MonoPosixHelper"
target="/home/userX/buildroot/output/host/usr/lib/libMonoPosixHelper.so"
os="!windows" />

Great!

Change that line and it should work. Now we should understand where that file
is generated that way ...

Crosschecked it...

- corrected ./buildroot/output/target/etc/mono/config

- removed the libMonoPosixHelper.so copy to home folder... at startup

And it works. Thanks.

Fixed.

Applied patch with copying to buildroot/package/mono
After 
> make clean
> make

buildroot/output/target/etc/mono/config shows the correct path for
libMonoPosixHelper.so without any prefix and accordingly bzImage works as
expected. 

Thanks
Markus
