[OpenIndiana-discuss] "Unexpected" error

[Apostolos Syropoulos]

Hi again,
According to the 5th answer of a similar question posted to Stack Overflow
https://stackoverflow.com/questions/19768267/relocation-r-x86-64-32s-against-linking-error
if the third command produces no output, the static library is not position-independent and cannot be used to generate a shared object.

apostolo at adalind:/tmp$ ar -x libgfortran.a 
apostolo at adalind:/tmp$ file async.o 
async.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped
apostolo at adalind:/tmp$ readelf --relocs async.o | egrep '(GOT|PLT|JU?MP_SLOT)'
apostolo at adalind:/tmp$ 

Provided the above is correct, the static library was not build the proper way.
Best regards,A.S.

 I expect that all code needs to be built position independent. So -fpic or -fPIC in CFLAGS.

Hello,
I am trying to compile R on my system and compilationstops with the following error:
make[4]: Entering directory '/container/source/lang/R-4.5.2/src/modules/lapack'
gcc -std=gnu23 -shared -fopenmp -L/usr/local/lib -o libRlapack.so dlamch.o dlapack.o cmplx.o dlartg.o dlassq.o la_constants.o la_xisnan.o zlartg.o zlassq.o    -L"../../../lib" -lRblas -R/usr/gcc/14/lib/amd64 -lgfortran -lm -lquadmath

collect2: error: ld returned 1 exit status
make[4]: *** [Makefile:117: libRlapack.so] Error 1

It seems that something is 32bit while everything is 64bit But
objdump -f libgfortran.a|grep ^architecture
says that everything is 64bit and all the object files are 64bit files!So what is wrong? Does anyone have any idea?

Apostolos
