undefined reference to 'osint__B83s'

[aytey]

I am trying to build gnat-llvm as follows:

git clone https://github.com/AdaCore/gnat-llvm.git
cd gnat-llvm
git clone git://gcc.gnu.org/git/gcc.git llvm-interface/gcc
ln -s gcc/gcc/ada llvm-interface/gnat_src
cd llvm
make setup
cd llvm-project-16.0.6.src
for i in ../patches/*; do patch -p1 < $i; done  ## massage some paths here
cd ..
make llvm
cd ..
make

and here is the output at the end:

/home/avj/opt/alire/gnat-x86_64-linux-14.2.0-1/bin/../lib/gcc/x86_64-pc-linux-gnu/14.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /mnt/baranem/llvm-gnat/source
s/gnat-llvm/llvm-interface/obj/osint-c.o: in function `osint__c__set_output_object_file_name':
/mnt/baranem/llvm-gnat/sources/gnat-llvm/llvm-interface/gnat_src/osint-c.adb:474:(.text+0x27e5): undefined reference to `osint__B83s'

This is with using:

both from Alire.

Am I missing a step?

This looks like a compiler (GCC) bug unfortunately.

[aytey]

Are you able to tell me what commits of https://github.com/AdaCore/gnat-llvm.git and git://gcc.gnu.org/git/gcc.git, as well as the version of Alire that are compatible?

Please see issue #49 which gives all the details
