how to install Fortran -dev package using sudo yum

I have installed (GCC) 4.7.2 20121015 (Red Hat 4.7.2-5) already and jave also installed yum install gcc-gfortran . (Package gcc-gfortran-4.4.7-18.el6.x86_64)

But I'm getting error like :

/usr/bin/ld: cannot find -lgfortran
collect2: error: ld returned 1 exit status
make: *** [quadprog.so] Error 1

Please help me in installing -lgfortran. It seems like I need to install "Fortran -dev package providing the Fortran library". I do not know how to do that in RedHat/CentOS. Please help. I'm facing hard time in doing this.

I have tried installing libgfortran using:

yum install libgfortran

But it says:

Package libgfortran-4.4.7-18.el6.x86_64 already installed and latest version Nothing to do (Running in an interactive session, skipping clean step.)

More Info: I tried installing package quadprog for R and below are the logs:

回答1:

The following compile line was looking for libgfortran at /usr/lib64/R/lib but the library is not there. Hence, the linker error.

gcc -m64 -std=gnu99 -shared -L/usr/lib64/R/lib -o quadprog.so aind.o init.o solve.QP.compact.o solve.QP.o util.o -L/usr/lib64/R/lib -lRblas -lgfortran -lm -lgfortran -lm -L/usr/lib64/R/lib -lR

As we could not locate and modify the makefile. We created a symbolic link /usr/lib64/R/lib/libgfortran.so to /usr/lib64/libgfortran.so.3 and rerun the installation steps and it resolves the linker error.

This is a work around that we follow which resolves the issue

You showed us this:

# type -a gcc

 gcc is /opt/centos/devtoolset-1.1/root/usr/bin/gcc 
 gcc is /usr/bin/gcc'

It means that you have installed Red Hat Developer Toolset and enabled it for this shell, using scl enable or a similar command. Do you still need it? If not, I suggest to disable it.

If you need DTS, you will have to install the Fortran compiler from DTS 1.1, using:

yum install devtoolset-1.1-gcc-gfortran

(Or download it directly from here, which seems to be the repository from where you got your DTS compiler.)

This will install the Fortran compiler which is compatible with the gcc compiler you have configured. Without that, the system Fortran compiler and the DTS gcc are used together, which does not work because the DTS gcc command (used for linking in the build process you quoted) is not able to locate the libgfortran.so library from the system Fortran compiler.

Alternatively, you can bring the two compilers into sync by deinstalling the DTS compiler:
