            Bug ID: 111027
           Summary: Install error "tmp-header-vars: Permission denied",
                    build on NFS, improvement possible
           Product: gcc
           Version: 13.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other

  Target Milestone: ---

On an ARM32 Linux system just installed, i.e. parallellla board just flashed
with an SDCard image at
https://github.com/parallella/parabuntu/releases/download/parabuntu-2019.1-beta1/parabuntu-2019.1-beta1-headless-z7010.img.gz
, full compilation works fine with:

mkdir vega
# limited SDCard storage so:
sudo mount 192.168.1.84:/home/etienne/parallella /home/parallella/vega
cd vega
wget https://ftp.gnu.org/gnu/gcc/gcc-13.2.0/gcc-13.2.0.tar.xz tar xf
gcc-13.2.0.tar.xz 
cd gcc-13.2.0/
./contrib/download_prerequisites
cd ..
mkdir gcc_build
cd gcc_build
../gcc-13.2.0/configure --enable-languages=c,c++,fortran
time make -j 3    # SDCard real 2033m27.533s / NFS real: 2065m36.178s

But install fails with:
$ echo parallella | sudo -S make install

The problem is simple, I am just creating this bug report so that people can
google it.

That is the first time "root" (due to sudo) tries to create a simple file in
the build directory, and such build directory is mounted on a NFS filesystem.
The NFS server may not configure the export with "no_root_squash", so that a
standard user can create such a file "tmp-header-vars", but root cannot!

Maybe a simple test (and a better error message) could be created when root
cannot create a file in the build directory? Obviously root will create files
without problems on /usr/local/{bin,lib,....}.

Feel free to classify as "NOTABUG", just keep it accessible in search engines!

Best Regards, Etienne.

I think the bug is that make install writes to the build directory at all (OTOH
libtool tends to re-link, but this instance seems to be different).

Confirmed.

Introduced in r0-97381-g090fa0ab610a for GCC 4.5.0 so it is techincally a
regression.

Parallella box is free again.
Proposed patch (with a slight offset) is recompiling, result in 2065m36.178s...

Hello, full recompilation from source finished (your patch included), same
setup with NFS without "no_root_squash" on /home/parallella/veg, installation
goes further but stop at:
