RISCV installation error : make: g++: Command not found

riscv · 03-22-2017, 07:18 AM

Hello,

I'm installing riscv-tools found at riscv.org.

These are the commands i've run (after cloning the riscv-tools repository)

PATH=$PATH:/home/alpha/riscv-tools
export PATH=$PATH:/home/alpha/riscv-tools
git submodule update --init --recursive
export RISCV=/home/alpha/riscv-tools
export PATH=$PATH:/home/alpha/riscv-tools/bin

With CC=gcc-5 CXX=g++-5 ./build.sh
I get:

Code:

make: *** [disasm.o] Error 4

with CC=gcc-4.8 CXX=g++-4.8 ./build.sh
I get:

Code:

Can you please tell me what I'm doing wrong (in beginner level explanation please) ? Thank you

Thank you for replying.

So i removed it all and redid it. The same error occurs.

for the g++,i've tried:
sudo apt-get install g++
./build.sh
and
export RISCV=/home/alpha/riscv-tools && ./build.sh

and for fatal: Not a valid object name HEAD, i've used:
git symbolic-ref HEAD refs/heads/my-branch

The outcome is:

Code:

? What does that mean ? Please elaborate.
""git symbolic-ref HEAD refs/heads/my-branch"" doesn't seem to be required.

Quote:

g++: Command not found

Are you sure g++ is installed ? Please test : $ g++
... The command g++ should answer with "g++: fatal error: no input files".

Hello,

Apparently even when i installed g++ it was still appearing as not installed. So i reinstalled it and it worked. But i still have errors related to gcc (libiberty for example).

The riscv-tools directory looks like this:

Code:

build.common      build.sh             build-spike-pk.sh  regression.sh  riscv-fesvr          riscv-isa-sim  riscv-opcodes  riscv-tests
build-rv32ima.sh  build-spike-only.sh  README.md          riscv          riscv-gnu-toolchain  riscv-llvm     riscv-pk

I'm trying to install the riscv-gnu-toochain which looks like this:

Code:

bin    build-binutils-newlib  config.log     configure     hello.c  lib      linux-headers  Makefile.in  riscv64-unknown-elf  riscv-dejagnu  riscv-glibc   scripts  src
build  build-gcc-newlib       config.status  configure.ac  include  LICENSE  Makefile       README.md    riscv-binutils-gdb   riscv-gcc      riscv-newlib  share    stamps

So i run the following from the riscv-tools directory:

Code:

git submodule update --init --recursive
sudo apt-get install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils 
export TOP=$(pwd)
export RISCV=$TOP/riscv
export PATH=$PATH:$RISCV/bin
export MAKEFLAGS="$MAKEFLAGS -j5"
./build.sh

Now, the ./build.sh looks like this

Code:

#! /bin/bash
#
# Script to build RISC-V ISA simulator, proxy kernel, and GNU toolchain.
# Tools will be installed to $RISCV.

. build.common

echo "Starting RISC-V Toolchain build process"

build_project riscv-fesvr --prefix=$RISCV
build_project riscv-isa-sim --prefix=$RISCV --with-fesvr=$RISCV
build_project riscv-gnu-toolchain --prefix=$RISCV
CC= CXX= build_project riscv-pk --prefix=$RISCV --host=riscv64-unknown-elf
build_project riscv-tests --prefix=$RISCV/riscv64-unknown-elf


echo -e "\\nRISC-V Toolchain installation completed!"

At the riscv-gnu-toolchain stage: it yields this error:

Re #5.

"libiberty.a" :
The binutils development files are probably required to compile the internal gcc :
/usr/lib64/libiberty.a
But may be the file isn't supplied with the default binutils for your OS ?

Or may be it is intended that you use the {riscv binutils-newlib libiberty.a} ?
I have this ...

Code:

/home/knudfl/riscv-tools/riscv-gnu-toolchain/build/build-binutils-newlib/libiberty/libiberty.a

... Please check your "/home/alpha///riscv-tools/lib/" folder for presence of libiberty.a, etc.
... And then include "riscv-tools/lib/" in the LD_LIBRARY_PATH

riscv · 03-24-2017, 11:38 AM

Re,

I didn't find libiberty in /usr/lib

and /home/alpha/installation/rocket-chip/riscv-tools/lib/ doesn't have any lib folder:

Code:

build.common      build.sh             build-spike-pk.sh  regression.sh  riscv-fesvr          riscv-isa-sim  riscv-opcodes  riscv-tests
build-rv32ima.sh  build-spike-only.sh  README.md          riscv          riscv-gnu-toolchain  riscv-llvm     riscv-pk

On the other hand, i've followed your path and found it here: /home/alpha/rocket-chip/riscv-tools/riscv-gnu-toolchain/build/build-binutils-newlib/libiberty/libiberty.a

So do i add that path to LD_LIBRARY_PATH (export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home//home/alpha/rocket-chip/riscv-tools/riscv-gnu-toolchain/build/build-binutils-newlib/libiberty/lib) ? Or should i create a lib folder inside of the riscv-tools and add it?

Thank you !

knudfl · 03-24-2017, 02:31 PM

Re #5, #6.

No libiberty.a was asked for in the two test runs I did today :
1) With PCLinuxOS 2017 - x86_64
2) With CentOS 7.3.1611 - x86_64
..... No errors at all.

Code:

[knudfl@localhost riscv-tools (master)]$ export RISCV=/home/knudfl/riscv-tools
[knudfl@localhost riscv-tools (master)]$ export PATH=$PATH:$RISCV/bin    
[knudfl@localhost riscv-tools (master)]$ ./build.sh 

.
.
.

Installing project riscv-tests

RISC-V Toolchain installation completed!

Ubuntu, Debian, Mint : libiberty.a is in the package libiberty-dev :
/usr/lib/x86_64-linux-gnu/libiberty.a
https://packages.debian.org/jessie/a...y-dev/filelist

$ sudo apt-get install build-essential

That should grab the gcc, g++, make, and other compile type things. Toolchains are normally in addition to these things so the compiler can get passed the right flags and output to the right location(s). Toolchains are not a replacement for the compilers. In general anyway. When in doubt, compile on the platform you are compiling for, it simplifies things greatly. Although it tends to be slower if it's not the same architecture.

knudfl · 03-25-2017, 07:12 AM

@riscv.

I made a third build of the riscv-tools : Ubuntu 14.04 - 64bits.
No errors, no "libiberty-dev" required : Ubuntu 14.04 has a native gcc-4.8 compiler.

A later Ubuntu version : The gcc-5 (g++-5) is known to fail with certain applications.

knudfl · 03-25-2017, 10:51 AM

@riscv.

So I made another test (4), now with Ubuntu 16.04 - x86_64. ( gcc-5, g++-5 ). No errors.

? Did you ever tell which OS you are using ?

riscv · 03-26-2017, 03:47 PM

@Shadow 7. Thank you for your anwer and explanation. I did install buid-essential, the libiberty.a error is still there after building the toolchain.

@knudfl: i'm using a 16.02 ubuntu (virtual machine) and the gcc version i'm using now is 6.2.
I know in the manual it says >= 4.8 for 14.04. Could you please explain why it only works with those versions ? Will it not work with the versions i'm using ? Also, what difference does the compiler version make for riscv ?

Thank you.

knudfl · 03-26-2017, 04:56 PM

Re #12.

Quote:

Indicates a wrong gcc version.

Quote:

the manual it says >= 4.8 for 14.04

... Means 4.8 or later. But obviously not the Ubuntu 16.10 gcc-6 that you installed.
Riscv tools contains two year old files, not meant to be build with "the gcc of tomorrow".

Quote:

Do you mean 16.04 or 16.10 ? ?
This command will show : $ cat /etc/issue

Shadow_7 · 03-26-2017, 05:45 PM

The libs that end in .a are for static linking. Perhaps there's an --enable-shared option that gets past it's absence, by using the .so. Or recompile the lib with --disable-shared or --enable-static, whatever applies to create the .a variant.

riscv · 03-26-2017, 05:45 PM

Sorry my bad (gcc 6.2) but the linux version is 16.04.

So i removed gcc and g++ and now they're 5.3.1 (after running apt-get install gcc-5 g++-5).
Running ./build.sh yields the same error.
