Changing INSTALL_DIR in generated Makefile doesn't trigger an install to the new location

[omerguzelelectronicguy]

When I compile the toolchain it is directly installed in the given directory. I wanted to move the executables to another directory. For example, I can do it in riscv-isa-sim by changing makefile and running make install however I couldn't make it in this repo. Could anyone help me with how to make it?

I thought directly move the binaries however I afaraid the corruption because of the paths. I also don't know what I need to move exactly ( executables and libraries others?).

Specify your desired install directory using configure --prefix=<install-dir>?

What corruption are you referring to here?

Copying the toolchain top level directory works fine for me - e.g.

git clone https://github.com/riscv-collab/riscv-gnu-toolchain issue-1398
cd issue-1398
./configure --prefix=`pwd`/installed-tools
make

cp -r installed-tools installed-tools-copy

Please be more specifc about what actual problems you face when copying/moving the toolchain and provide reproducible test case details/instructions.

This worked for me:

Create a simple test program:

cd ~/Downloads
vi hello.c 

...

// hello.c
#include <stdio.h>

int main(int argc, char *argv[])
{
    printf("Hello, World!\n");
    return 0;
}

Build the toolchain:

cd ~/Downloads
git clone https://github.com/riscv-collab/riscv-gnu-toolchain issue-1398
cd issue-1398
./configure --prefix=`pwd`/installed-tools
make

Compile the test program:

./installed-tools/bin/riscv64-unknown-elf-gcc -v ~/Downloads/hello.c -o hello

If you want to build a toolchain that can be copied to another machine or even distro, and not just to another location on the build machine, then maybe look at the following:

• crosstool-NG
• xPack GNU RISC-V Embedded GCC
  • Build Details
    • https://github.com/xpack-dev-tools/riscv-none-elf-gcc-xpack/blob/xpack/README-MAINTAINER.md

The issue title:

when install dir is changed in Makefile, make is not working

doesn't really correlate to the issue description:

When I compile the toolchain it is directly installed in the given directory. I wanted to move the executables to another directory. For example, I can do it in riscv-isa-sim by changing makefile and running make install however I couldn't make it in this repo. Could anyone help me with how to make it?

I thought directly move the binaries however I afaraid the corruption because of the paths. I also don't know what I need to move exactly ( executables and libraries others?).

But, in any case, my previous post addresses your issue as far as I can see.

[omerguzelelectronicguy]

I'm sorry for not getting back to you sooner. let me explain my problem in more detail.

I am working in a directory called my_dir. I installed the toolchain to my_dir by giving --prefix=/home/omer/mydir. Checked it. It is working fine. Then I wanted to install the toolchain to /opt/riscv I changed the install dir in the makefile from /home/omer/mydir to /opt/riscv and run make again. It returned "make: Nothing to be done for all'". So, couldn't install the compiled toolchain to /opt/riscvin this way. (It worked when I installed spike again to a different directory). I also tried to run../configure --prefix=/opt/riscvin my build directory and run make. It returned "make: Nothing to be done forall'".

I understand that my_dir is replaceable and can work anywhere when I copy it. So, I can copy the insiders of my_dir to /opt/riscv/.. However, I already installed the spike to /opt/riscv so there are already bin, lib, include directories that created by spike installation. I was afraid to harm them if I do it manually(I didn't try).

[omerguzelelectronicguy]

When I was installing spike, make install was worked when I changed the install dir inside the Makefile. The compiled bin lib and include dirs are added to /opt/riscv/.` It doesn't work in the same in this repo. That is why I wrote the title like that. Excuse me if I make you confused.

It's better not to manually edit the generated Makefile.
It's better to use configure --prefix=<preferred-install-dir>.

It returned "make: Nothing to be done for `all'".

You need to do make distclean first to clean out the previously built artifacts otherwise the Makefile detects that there is nothing to be done even though the target install directory has changed.

But if you're only changing the target install ("prefix") directory then you can just copy the toolchain as I mentioned earlier instead of rebuilding the whole thing.

If you are copying to a "system" directory such as /opt/riscv which may be shared by multiple users then you might also want to change the file attributes (e.g. owner and group).

[TommyMurphyTM1234]

Closing as there is no problem identified here with the riscv-gnu-toolchain.

I guess that the Spike Makefile has something that detects a change to the target install directory as an indication that it needs to do something (specifically do the "install" copying of build artefacts) but the riscv-gnu-toolchain one does not. Maybe some or most other projects also have that capabilitity but I supect that because riscv-gnu-toolchain is basically an integration of multiple other (mostly) upstream projects (GCC, GDB, Binutils, glibc, Newlib, LLVM, Spike, QEMU etc.) it does not do this.

But, in any case, an already built/installed riscv-gnu-toolchain can safely be copied to another install directory on the same machine as mentioned earlier.
