I have following the instructions to compile and install GCC 15.2.0 from:
GCC 15.1 with C++26 on Ubuntu | by Alex Lykov |
Medium<https://medium.com/@xersendo/moving-to-c-26-how-to-build-and-set-up-gcc-15-1-on-ubuntu-f52cc9173fa0>
(I changed the checkout gcc-15.1.0 to gcc-15.2.0)
Make has failed with the following errors:
