[Rd] Incorrect behavior in 64-bit version (PR#11034) (solved)

[Lodewijk Bonebakker]

Peter,

thank you for your reply, the provided link had the answer:

The problem is the Sun cc compiler not following the C99 syntax  
standard. Adding -xc99 to compiler flags fixed the problem.

My incorrect assumption was that configure.in would contain most of  
the recommended flags for compilation, combined with using the same  
wrapper script for compilation that has worked successfully since  
version 1.9. Obviously it is no longer current and I have added 'make  
check' as additional safety.

Thank you again,

Lodewijk Bonebakker


For general interest (since this is going to be public anyway), here  
is my wrapper script:

#!/bin/bash
## quick-buildR,64
##
## build R, libiconv and readline should be installed in /usr/sfw/lib/ 
amd64
##
export CC="cc -xc99"
export CPP=""
export CXX=CC
export FC=f95
export F77=f95
##
export BASEFLAGS="-m64 -I/usr/sfw/include"
# export FPICFLAGS="-Bdynamic -G"
# export CXXPICFLAGS="-pic"
# export SHLIB_CXXFLAGS="-Bdynamic -G"
# export MAIN_CFLAGS="-m64 -I/usr/sfw/include"
# export SHLIB_CFLAGS="-m64"
# export MAIN_FFLAGS="-m64"
# export SHLIB_FFLAGS="-m64"
##
export CFLAGS="${BASEFLAGS} -O -xO5 -xc99 -xlibmieee -xlibmil -nofstore"
export FFLAGS="${BASEFLAGS} -O5 -libmil -nofstore"
export CXXFLAGS="${BASEFLAGS} -O -xO5 -xlibmil -nofstore"
export FCFLAGS=${FFLAGS}
export SHLIB_CXXLDFLAGS="-G -lCstd"
export SAFE_FFLAGS="-O5 -libmil -fstore"
##
export LDFLAGS="-m64 -L/usr/sfw/lib/amd64  -L/usr/sfw/lib"

##
./configure --prefix=/opt/R/v2.6.2,64 --with-blas=sunperf --with-lapack

RESULT=$?
if [ $RESULT -eq 0 ]; then
         gmake
         RESULT=$?
fi
if [ $RESULT -eq 0 ]; then
         gmake check
	RESULT=$?
fi
if [ $RESULT -eq 0 ]; then
         gmake install
         RESULT=$?
fi
echo "RESULT $RESULT"

## end of script
