Relocations in generic ELF (EM: 183)

Hi,

I used to be able to cross-compile a program for aarch64 architecture with arm cpus with:

./configure --host=aarch64-linux-gnu --prefix=/data/data/papi/independent --exec-prefix=/data/data/papi/dependent --with-static-lib=yes --with-shared-lib=no --with-static-tools --with-arch=aarch64 --with-CPU=arm --with-ffsll --with-walltimer=cycle --with-tls=__thread --with-virtualtimer=clock_cputime_id --with-perf-events

But now, after running make, I'm getting this error:
mpicc -I../testlib -I../validation_tests -I.. -I. -g -Wextra -DUSE_PTHREAD_MUTEXES -Wall -O1 first.c ../testlib/libtestlib.a ../testlib/do_loops.o ../libpapi.a -ldl -static -o mpifirst

Running file on test_utils.o gives:
test_utils.o: ELF 64-bit LSB relocatable, ARM aarch64, version 1 (SYSV), not stripped

Makefile.recipies:230: recipe for target 'mpifirst' failed corresponds to:
mpifirst: mpifirst.c $(TESTLIB) $(DOLOOPS) $(PAPILIB)
$(MPICC) $(INCLUDE) $(MPFLAGS) $(CFLAGS) $(TOPTFLAGS) first.c $(TESTLIB) $(DOLOOPS) $(PAPILIB) $(LDFLAGS) -o mpifirst -lpthread

Looks fine to me :/

Any ideias on how to solve it?

Thanks,
Luís

I think the lib ../testlib/libtestlib.a is not ok (not relocatable)

Thanks for the reply @pan64

According to another thread, I was invoking the wrong system linker and probably the wrong compiler too.

Running:

Code:

mpicc -c  -I../testlib -I../validation_tests -I.. -I.  -DUSE_PTHREAD_MUTEXES first.c
file first.o

Gives:

Code:

ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped

Running:

Code:

$ mpicc --print-multiarch

Gives:

Code:

x86_64-linux-gnu

I don't know how to change the triplet or chose the right path, so that, mpicc finds the right toolchain compiler (aarch64-linux-gnu-)

Thanks,
Luís
