Problem in installation of Qbox in Ubuntu 20.04

[rajorshi]

Dear All,

I am trying to install Qbox code in my Ubuntu 20.04 machine and g++ - 9.4.0. I am using the gcc_atlas.mk build file provided in the build directory. I have installed all the libraries required and have provided the paths to them in the .mk file. However, I still get the following error-

/usr/bin/ld: /home/rajorshi/Downloads/scalapack-2.2.0/libscalapack.a(pxerbla.o): undefined reference to symbol '_gfortran_transfer_integer_write@@GFORTRAN_8'
/usr/bin/ld: /usr/lib/x86_64-linux-gnu/libgfortran.so.5: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make: *** [Makefile:65: qb] Error 1

The .mk file I have used is as follows:

# gcc_atlas.mk
PLT=Linux_x8664
SCALAPACKDIR = $(HOME)/Downloads/scalapack-2.2.0
XERCESCDIR=$(HOME)/Downloads/xerces-c-3.2.3/src/.libs
ATLASDIR=/usr/lib/x86_64-linux-gnu/atlas

PLTOBJECTS = readTSC.o
SVN_VER :=$(shell svnversion -n)
DFLAGS += -DSVN_VERSION='"$(SVN_VER)"'

CXX=mpicxx
LD=$(CXX)

PLTFLAGS += -DIA32 -D_LARGEFILE_SOURCE \
-D_FILE_OFFSET_BITS=64 -DUSE_MPI -DSCALAPACK -DADD_ \
-DAPP_NO_THREADS -DXML_USE_NO_THREADS -DUSE_XERCES \
-DMPICH_IGNORE_CXX_SEEK

# FFT must be FFTW2, FFTW3, ESSL or NOLIB
FFT=FFTW2

ifeq ($(FFT),FFTW2)
PLTFLAGS += -DUSE_FFTW2
PLTFLAGS += -DFFTWMEASURE

LIBS += -lfftw
endif

ifeq ($(FFT),FFTW3)
PLTFLAGS += -DUSE_FFTW3
PLTFLAGS += -DFFTWMEASURE
#PLTFLAGS += -DFFTW_TRANSPOSE
PLTFLAGS += -DFFTW3_2D
FFTWDIR=$(HOME)/software/fftw/fftw-3.3.4
FFTWINCLUDEDIR=$(FFTWDIR)/api
FFTWLIBDIR=$(FFTWDIR)/.libs
INCLUDE += -I$(FFTWINCLUDEDIR)
LIBPATH += -L$(FFTWLIBDIR)
LIBS += -lfftw3
endif

ifeq ($(FFT),ESSL)
$(error ESSL library not available)
endif

ifeq ($(FFT),NOLIB)
PLTFLAGS += -DFFT_NOLIB
endif

INCLUDE += -I$(XERCESCDIR)/include

CXXFLAGS= -g -O3 -Wunused -D$(PLT) $(INCLUDE) $(PLTFLAGS) $(DFLAGS)

LIBPATH += -L$(XERCESCDIR)/lib \
-L$(ATLASDIR) -L$(SCALAPACKDIR) -L/usr/lib64

LIBS += -lpthread -lxerces-c -lscalapack -llapack -lf77blas -latlas

LDFLAGS = $(LIBPATH) $(LIBS)

Can anyone help me solve this issue ? I thank you in advance

Hello,

From the error message, it seems that it misses symbols from the gfortran library. It may be resolved by adding -lgfortran to your link line, after "-latlas".

In case this is still not working, I include below another arch file that was used on an Ubuntu platform. The packages to be installed are listed at the beginning of the file.

Please let me know if you still have problems.

Francois
