Install g++ from source in Fedora 26

Question

I am trying to install a c++ compiler on a IBM Power7 with Fedora 26. In /usr/bin it is installed gcc [(GCC) 7.2.1 20170915 (Red Hat 7.2.1-2)] but it has not the c++ compiler (I tried gcc -lstdc++ but the result is: `

/usr/bin/ld: cannot find -lstdc++

I do not have sudo rights so I have to install everything from source. I was able to install:

• Zlib
• Perl
• Curl
• Git
• GNU M4
• GMP
• MPFR
• MPC
• EXPAT
• APR and APR-UTIL
• ISL

but when I try to install locally gcc, after a successfull configure , when I try make I got this error:

configure: error: in `/home/aantonietti/gcc/host-powerpc64-unknown-linux-gnu/gcc':

configure: error: C++ preprocessor "/lib/cpp" fails sanity check

See `config.log' for more details.

make[2]: *** [Makefile:4333: configure-stage1-gcc] Error 1

make[2]: Leaving directory '/home/aantonietti/gcc'

make[1]: *** [Makefile:23745: stage1-bubble] Error 2

make[1]: Leaving directory '/home/aantonietti/gcc'

make: *** [Makefile:945: all] Error 2

I also tried to install clang++ but it needs tons of other dependecies.

Do you have any hint on how to install just the gcc-c++ compiler?

Answer 1

Why don't you run dnf install gcc-c++ ? It will install the C++ system compiler bring in linking support for libstdc++ as well.
