I can't compile R-alpha on AMD 64. Rather than include a 1400 line script
I have put it on the web
http://www.stat.umn.edu/~charlie/typescript.txt
way down near the bottom it fails building lapack.so
gcc -shared -L/usr/local/lib64 -o lapack.so Lapack.lo -llapack -lblas
-lg2c -lm -lgcc_s
/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.5/../../../../x86_64-suse-linux/bin/ld:
/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.5/../../../../lib64/liblapack.a(dgecon.i):
relocation R_X86_64_32 against `a local symbol' can not be used when making a
shared object; recompile with -fPIC
/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.5/../../../../lib64/liblapack.a:
could not read symbols: Bad value
The 'recompile with -fPIC' is bullsh*t. The problem is that is is looking
in /usr/lib64/liblapack.a rather than /usr/lib64/liblapack.so.3 both of which
exist. Some searching for this error message on Google shows a lot of
questions about this problem but no solution that I found other than
rm /usr/lib64/liblapack.a
which I don't consider a solution. It will link with the .so as the bottom
of the script shows
snowbank$ cd src/modules/lapack
snowbank$ gcc -shared -o lapack.so Lapack.lo -llapack -lblas -lg2c -lm
-lgcc_s
/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.5/../../../../x86_64-suse-linux/bin/ld:
/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.5/../../../../lib64/liblapack.a(dgecon.i):

/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.5/../../../../lib64/liblapack.a:

collect2: ld returned 1 exit status
snowbank$ gcc -shared -o lapack.so Lapack.lo /usr/lib64/liblapack.so.3
-lblas -l g2c -lm -lgcc_s
No problems with the second link.
So what do I do? liblapack.so is there. I've linked other (non-R) programs
to it. So it SHOULD work with R.
Either I can't read (possible) or the solution to this isn't in the gcc info
pages.
System (more info in typescript).
AMD 64
SuSE linux 9.3
GCC 3.3.5
I also observed the same problem with R-2.1.1 but didn't get around to
debugging it until today.
It occurred to me that /usr/local/lib/liblapack.so.3 which is 32 bit
(because right now we are running only one R on both 32 and 64 bit and
that's where the 32 bit R finds it's shared libraries), but I don't
think that's the problem. Well maybe it is. How do I tell configure
NOT to add /user/local ?
