Stage2 install issue

[rezso]

Install docs stage2 (i686-unknown-linux-gnu)
touch: cannot touch '/usr/lib/rust-install-probe': Permission denied
install: error: can't write to destination. consider sudo.

command did not execute successfully: "sh" "/var/uhubuild/work/compile/build/tmp/dist/rust-docs-1.18.0-i686-unknown-linux-gnu/install.sh" "--prefix=/usr" "--docdir=/usr/share/doc/rust" "--libdir=/usr/lib" "--mandir=/usr/share/man" "--disable-ldconfig"
expected success, got: exit code: 1

Why NEED to run install 3 times, and why not works under chroot?

[Mark-Simulacrum]

Without more details, I don't think this issue is actionable. Can you create the file manually (touch /usr/lib/rust-install-probe)? I don't know what you mean by "need to run install 3 times," I believe make install should install rust into the configured directories.

[Mark-Simulacrum]

Closing. Let us know if you can respond to my questions above and we'll reopen.

[rezso]

Sorry, I don't saw your questions, I think the email is lost.
So, I build everything under chroot. This means, I need to create /var/uhubuild/work/install/usr/lib/rust-install-probe instead of /usr/lib/rust-install-probe. I don't saw any option to add install prefix,
And yes, I can create manually, but this file will be lost on the next or restarted build, because rust compiled 3 times.
But because I need rust compiler just for compiling a small rust code in Firefox, I simply use the precompiled binary now.

don't saw any option to add install prefix

You should be able to copy src/bootstrap/config.toml.example next to x.py and edit the prefix field under [install] to specify an installation prefix.

I'm still not clear what you mean by rust will compile 3 times, but perhaps you're referring to the compiler bootstrapping itself. A build log would be helpful. Using precompiled binaries is probably a good bet for compiling firefox, though installing from source should work.

[Mark-Simulacrum]

@rezso Is there a chance you could get back to me if adding the prefix worked? A build log would be appreciated as well, and if possible, full reproducible steps.

[rezso]

The build system always tries to download anything, but it fails, because the internet connection not works for me under chroot currently (I don't know why, previously worked):

I tried to compile the 1.20 release from relase tarball.

[rezso]

Okay, I solved the network error.
I try to compile 1.20.0 on 64 bit:

I get similar "thread 'main' panicked" error with precompiled 64-bit binary, if I try to compile firefox with it:

This happens on 64-bit only, on 32-bit no problem.

[rezso]

Solved.
I have llvm 4.0, which is not contains the /usr/bin/FileCheck binary. Setting codegen-tests to false solves this.
In the install, the liblzma.{a,la,pc} and header files are installed, so rust package conflicts with xz-dev package.
If I set docs to false, the build fails:
Nothing to run...

Triage: this is a very old issue, and the last comment says "solved", so, closing!
