No PLT for relocation

["Dr. Peter Zumbruch" <P.Zumbruch@gsi.de>]

Hello everybody,

I am trying to cross compile and link an application based on stream 
device and asyn
with patched base 3.14.10 on a linux-x86_64 system with the 
linux-cris_v10 as target.

Stream and Asyn have been compiled for the host and target architectures.
When building the application the final linking for the target failes 
with this command
(which I just split up for better reading, and paths shortened <..>):

> cris-g++ -o streamHadcon
> -Wl,-Bstatic -static-libgcc
> -Wl,--strip-all
> -L<IOC_TOP>/lib/linux-cris_v10
> -L<EPICS_HOME>/base/lib/linux-cris_v10
> -L<EPICS_HOME>/modules/soft/StreamDevice/lib/linux-cris_v10
> -L<EPICS_HOME>/modules/soft/asyn/asyn-4.11a/lib/linux-cris_v10
> -Wl,-rpath,<IOC_TOP>/lib/linux-cris_v10
> -Wl,-rpath,<EPICS_HOME>/base/lib/linux-cris_v10
> -Wl,-rpath,<EPICS_HOME>/modules/soft/StreamDevice/lib/linux-cris_v10
> -Wl,-rpath,<EPICS_HOME>/modules/soft/asyn/asyn-4.11a/lib/linux-cris_v10
> -L<AXIS_TOP>/target/cris-axis-linux-gnu/lib
> -L<AXIS_TOP>/target/cris-axis-linux-gnu/usr/lib
> streamHadcon_registerRecordDeviceDriver.o streamHadconMain.o
> -lstreamHadconSupport
> -lrecIoc
> -lsoftDevIoc
> -lmiscIoc
> -lrsrvIoc
> -ldbtoolsIoc
> -lasIoc
> -ldbIoc
> -lregistryIoc
> -ldbStaticIoc
> -lca
> -lCom
> -lstream
> -lasyn
> -lpthread
> -lm
> -lrt
resulting in this output:

> <EPICS_ASYN>/lib/linux-cris_v10/libasyn.a(devAsynInt32.o): In function 
> `getIoIntInfo':
> epicsTypeClass/../../asyn/devEpics/devAsynInt32.c:288: undefined 
> reference to `epicsRingBytesCreate'
> [..]/cris-axis-linux-gnu/bin/ld:

> [..]/cris-axis-linux-gnu/bin/ld: final link failed: Bad value
> collect2: ld returned 1 exit status
Notes:
- But 'epicsRingBytesCreate' is defined in libasyn.a(devAsynInt32.o), 
(cris-)nm gives consistent results
- Unfortunately in addition I do not fully get the meaning of the error
- It does compile for linux-x86_64
- base itself needed an independent patch for _64 architecture in base 
CONFIG.linux-x86_64.linux-cris(_v10/32) copy linux-x86 (to be committed 
soon)


Since I did the port of EPICS to cris,
has anybody else seen such a response or something similar when cross 
building an application?

Any help appreciated,

Thanks, Peter
