fedora 22: ld: cannot find -lstdc++

I'm having trouble installing this library. I tried the x86_64 and i686 version and I'm still getting ld:cannot find -lstdc++

I installed:

Code:

dnf install libstdc++-devel

dnf install libstdc++

Code:

dnf install libstdc++-devel.i686

dnf install libstdc++.i686

What am I missing?

Thanks,

ld:cannot find -lstdc++

$ dnf provides */libstdc++.so

# dnf install gcc-c++.x86_84
( Provides /usr/lib/gcc/x86_64-redhat-linux/5.1.1/libstdc++.so )

Hey I ran the provides command:

Code:

$ sudo dnf provides */libstdc++.so

So I tried to install both x86_64 and i686 version of gcc-c++

Code:

$ sudo dnf install gcc-c++.x86_64

Nothing to do.

Complete!

However I'm still getting the same error of
ld -lstdc++
ld: cannot find -lstdc++

Thanks,

? Which software is it that "cannot find -lstdc++" ?

Well this came up from building a cross compile toolchain. I'm using crosstool-ng and was running:

Code:

./ct-ng build

[DEBUG]  Checking that gcc can statically link libstdc++ (CT_CC_GCC_STATIC_LIBSTDCXX)

[DEBUG]    You may need to ensure that libstdc++.a is installed on your system

But when I try to run this from the command line I can the same error.

Code:

$ ld -lstdc++

ld: cannot find -lstdc++

Thanks for you help.

Sorry I was getting confused I think the issue is the cross compiling is what is having the issues not the host machine.

Here is the command that is error-ing out:

Code:

./x86_64-build_unknown-linux-gnu-gcc \

        -O2 -g -pipe \

        /home/stralko/src/embedded-linux-labs/toolchain/crosstool-ng/.build/arm-cortexa5-linux-uclibcgnueabihf/build/test.c \

        -static -lstdc++ \

        -o /home/stralko/src/embedded-linux-labs/toolchain/crosstool-ng/.build/arm-cortexa5-linux-uclibcgnueabihf/build/.gccout

Re #5, #6.

Quote:

You may need to ensure that libstdc++.a is installed on your system

Please read post #2 about "dnf provides */<file>".
So why not use 'dnf provides */libstdc++.a' ?

The package libstdc++-static provides /usr/lib/gcc/x86_64-redhat-linux/5.1.1/libstdc++.a

Thank you so much. the dnf provides command is a life savior!
