[Rd] Matrix loading hangs on AIX 5.3 with 3.1.2
Hi all,
Yes, I know 5.3 is old, but it's a system I have to work with at present.
I have the latest supported xlC + friends. gcc building is not an option on
this system for other reasons.
I have read the install instructions and set the env vars according to those
and also am using the freeware iconv and other GNU tools where needed.
Problem - the Matrix package hangs on installing.
Gets to:
Loading required package: Matrix
and then nothing. Left overnight even.
My env vars look like this:
export OBJECT_MODE=64
export LIBICONV=/opt/freeware
export CC="xlc_r -q64"
export CFLAGS="-O -qstrict"
export CXX="xlC_r -q64"
export CXXFLAGS="-O -qstrict"
export F77="xlf_r -q64"
export AR="ar -X64"
export CPPFLAGS="-I$LIBICONV/include -I/usr/lpp/X11/include/X11"
export LDFLAGS="-L$LIBICONV/lib -L/usr/lib -L/usr/X11R6/lib"
xlc -qversion
IBM XL C/C++ for AIX, V12.1 (5765-J02, 5725-C72)
Version: 12.01..0011
xlC -qversion
IBM XL C/C++ for AIX, V12.1 (5765-J02, 5725-C72)
Version: 12.01..0011
xlf -qversion
IBM XL Fortran for AIX, V12.1
Version: 12.01..
I have tried with R_SHELL set to bash and ksh. My login shell is bash.
I have tried with enable static and disable shared.
I have subsequently built without recommended packages. R build and
installs. (Minor issue with the location of libRblas but I solved that.
I have then tried doing a install.packages("Matrix") from R.
Same thing. Hangs.
Any ideas?
I can supply more information as needed. Please let me know what you would
like to know.
Kind regards

I wouldn’t exactly know since I’m not using Windows.
Try this:
R CMD config LAPACK_LIBS
to see the command line options needed.
And why are you using dgemm_?
Use the F77_CALL macro provided by R; you’ll be less system dependent that way.

[Rd] Problem with shared library and lapack under windows
Hi all,
I have a C function, say Cfun, that calls Lapack's DGEMM routine and I need
to create a shared library to use Cfun inside R. The C file is the following
#include
#include
#include
void Cfun(double *res, double *X, int *n, int *q)
{
char *ptr_TRANSA, TRANSA='T', *ptr_TRANSB, TRANSB='N';
ptr_TRANSA=&TRANSA;
ptr_TRANSB=&TRANSB;
double *ptr_ALPHA, ALPHA=1.0, *ptr_BETA, BETA=0.0;
ptr_ALPHA=Α
ptr_BETA=Β
dgemm_(ptr_TRANSA, ptr_TRANSB, q, q, n, ptr_ALPHA, X, n, X, n, ptr_BETA,
res, q);
}
In Ubuntu I have no problem in compiling: R CMD SHLIB -llapack myfile.c.
However, under Windows the -llapack flag is not recognised and I am able to
get the code compiled only if I build an R package with the suitable
Makevars file options: PKG_LIBS=$(LAPACK_LIBS) $(FLIBS). Is there a way to
get the .dll without resorting to build a package?
Thanks in advance,
N. Lunardon
