gcc cannot find cc1plus

Question

I'm trying to install the python package pandas on CentOS 6 but I'm having problems with the gcc compiler:

sudo pip install pandas
...    
creating build/temp.linux-x86_64-2.7/pandas/msgpack

gcc -pthread -fno-strict-aliasing -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -DNDEBUG -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -D_GNU_SOURCE -fPIC -fwrapv -fPIC -D__LITTLE_ENDIAN__=1 -Ipandas/src/msgpack -Ipandas/src/klib -Ipandas/src -I/opt/rh/python27/root/usr/lib64/python2.7/site-packages/numpy/core/include -I/opt/rh/python27/root/usr/include/python2.7 -c pandas/msgpack/_packer.cpp -o build/temp.linux-x86_64-2.7/pandas/msgpack/_packer.o -Wno-unused-function

gcc: error trying to exec 'cc1plus': execvp: No such file or directory

error: command 'gcc' failed with exit status 1

Cleaning up...

So it appears I need cc1plus, which by reading around requires gcc-g++. But I already have gcc-c++:

sudo yum install gcc-c++
...
Package gcc-c++-4.4.7-16.el6.x86_64 already installed and latest version
Nothing to do

About gcc and cc1plus:

gcc --version
gcc (GCC) 4.8.2 20140120 (Red Hat 4.8.2-15)

which gcc
/opt/rh/devtoolset-2/root/usr/bin/gcc

locate cc1plus
/usr/libexec/gcc/x86_64-redhat-linux/4.4.4/cc1plus

My own solution below. Does anybody have better ways of addressing the problem?

Answer 1

Solution to my own question: It seems that cc1plus, although present, is not visible to gcc as it is not on path. So a solution is to link cc1plus to a directory on PATH:

sudo ln -s /usr/libexec/gcc/x86_64-redhat-linux/4.4.4/cc1plus /usr/local/bin/

Now sudo pip install pandas succeeds.

(But why the package manager put cc1plus there in the first place?)
