Dear all,
after trying to compile R on our IBM Power3/AIX 5.1 machine I've
been able to run it correctly.
First of all I would thank all who responded my mails.
I explain here how I've done it:
First of all, it seems that configure and some shared libraries of
AIX does not work at the same time. I tried to configure & make with
the following environment vars
CC=xlc
F77=xlf
CCC=xlC
CFLAGS=-O3 -qstrict -qmaxmem=8192
FFLAGS=-O3 -qstrict -qmaxmem=8192
MAIN_LDFLAGS=-Wl,-brtl
SHLIB_LDFLAGS=-Wl,-G
CXXFLAGS=-O2 -qmaxmem=8192
FC=xlf
CCFLAGS=-O3 -qstrict -qmaxmem=8192
But for some reason at make the compilation failed when trying to
locate a shared library for X. For this reason I tried to discard
shared libraries enabling --disable-shared on configure, but this
didn't help (Nor removing MAIN_LDFLAGS and SHLIB_LDFLAGS). Next I
tried to compile without X environment and I got the following error
...

Stop.
ERROR: compilation failed for package 'foreign'
make: 1254-004 The error code from the last command is 5.
...
At this point I was looking for foreign.h, but it was in a TAR.GZ!
I place comment on lines 51 and 52 for taking int16/int32 out
(as AIX headers does define them and XLC fails compiling --
while GCC continues showing only a warning!)
When those lines were commented I make a new TAR.GZ and update the
softlink to the modified version.
With this modifications the main program where created. Was time
for 'make check'... and failed! There was a problem on ESSL and
R, so I forced R not to use the default BLAS (ESSL) of the machine
(--without-blas).
After removing all temporal files, reconfiguring and recompiling
the make check WORK PROPERLY! :D
In brief, the environment I used to compile was
CC=xlc
F77=xlf
CCC=xlC
CFLAGS=-O3 -qstrict -qmaxmem=8192
FFLAGS=-O3 -qstrict -qmaxmem=8192
MAIN_LDFLAGS=-Wl,-brtl
SHLIB_LDFLAGS=-Wl,-G
CXXFLAGS=-O2 -qmaxmem=8192
FC=xlf
CCFLAGS=-O3 -qstrict -qmaxmem=8192
./configure --prefix=YOURDIRECTORY --without-x --without-blas
As our machine and our user plans to use R only for a compute
intesive calculations there's no need to use X. So this
compilation is perfect for our purposes.
Many thanks to all!,
