Can you upload the entire log file?

[minnyres]

Hi this is the entire log. log.txt

[firasuke]

I haven't tested mussel on Debian based distributions, and I haven't encountered this issue neither on Arch nor on Fedora.

It appears to be related to C++17 issues used with the latest isl 0.25, a workaround to solve this would be adding ax_cv_cxx_compile_cxx17=no \ before line 12 so that it becomes:

printf -- "${BLUEC}..${NORMALC} Configuring cross-gcc (compiler)...\n"
ax_cv_cxx_compile_cxx17=no \
$SRCDIR/gcc/gcc-$gcc_ver/configure \
  --prefix=$MPREFIX \
  --target=$XTARGET \
  --with-sysroot=$MSYSROOT \
  --enable-languages=c,c++ \
  --disable-multilib \
  --disable-bootstrap \
  --disable-libsanitizer \
  --disable-werror \
  --enable-initfini-array $XGCCARGS >> $MLOG 2>&1

[minnyres]

Thanks for your reply, but I still meet the error with this patch.

[firasuke]

That is weird, C++17 is only used for a test here. I think you'll have to wait until your host's compiler is actually capable of supporting C++17, or perhaps try passing ax_cv_cxx_compile_cxx17=no as a global environment variable and see if that works for you.

[minnyres]

try passing ax_cv_cxx_compile_cxx17=no as a global environment

still not working.

wait until your host's compiler is actually capable of supporting C++17

I will update the result when Debian upgrades to GCC 11 or 12.

[firasuke]

still not working.

That's unfortunate...

I will update the result when Debian upgrades to GCC 11 or 12.

Please do. I'll keep this issue open until then.

Yes, well disabling isl isn't a good idea here.

I see that you're using gcc 8.4.0, and I recommend trying with gcc 11 or 12, which in theory should fix this issue correctly.

[terefang]

linux mint 19.3 does not have gcc 11 or 12

i also checked LFS ... they also dont use isl

maybe i need to write my own build script

[firasuke]

I'm not saying you can't use ISL, but if you don't you'll miss on loop optimizations.

Quoting from the GCC install prerequisites page:

Necessary to build GCC with the Graphite loop optimizations. It can be downloaded from https://gcc.gnu.org/pub/gcc/infrastructure/. If an isl source distribution is found in a subdirectory of your GCC sources named isl, it will be built together with GCC. Alternatively, the --with-isl configure option should be used if isl is not installed in your default library search path.

Hope that clears up the confusion.

maybe i need to write my own build script

Well that's up to you, it's easier to fork this script and disable ISL only to enable it later on because eventually your distribution's GCC will be updated, than write your own script from scratch. Either ways good luck!

[terefang]

i would like to continue using your script.

would you mind adding an option like --without-isl to your script ?

the impact of not having isl in gcc is not that impacting in my usecase, as i use it to build only intermediate (stage 2) compilers.

as i final step, i would like to compile different sets (profiles ie. versions) of (stage 3) compilers with matching libraries like those given in the LFS documents or various distributions, maybe as far back as gcc3.

would you mind adding an option like --without-isl to your script ?

perhaps it is better to manually change the version of isl

That would also work, since isl version 0.24 doesn't require C++17.

But it's a temporary downgrade until gcc on Debian is updated to support C++17.

[firasuke]

@minnyres is this still an issue?

[minnyres]

Debian stable is still using GCC 10.2.1. The problem may be solved when GCC 11 or higher is available on Debian stable.

[minnyres]

It works in Debian 12 with GCC 12.2 so this issue can be closed.

[firasuke]

Glad that it is working again!
