Some more errors similar after fixing the above one:
In file included from src/runtime/Allocator.cpp:27:
./arm_compute/runtime/MemoryRegion.h:99:21: error: ‘uint8_t’ was not declared in this scope
99 | std::shared_ptr<uint8_t> _mem;
| ^~~~~~~
./arm_compute/runtime/MemoryRegion.h:31:1: note: ‘uint8_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’
30 | #include <cstddef>

Hi @pinskia
Could you please share these details?
g++ --version
or the corresponding cross-compiler you are usingThe version of GCC I am using:
[apinski@xeond2 upstream-cross-aarch64]$ ./install/bin/aarch64-linux-gnu-g++ -v
Using built-in specs.

gcc version 15.0.0 20240903 (experimental) [trunk 4beaa1846dc] (GCC)
This was the trunk version as of last week. as I should have mention adding #include <cstdint>
to the following files allowed me to do the testing I needed to do:
arm_compute/core/CPP/CPPTypes.h
arm_compute/runtime/MemoryRegion.h
tests/framework/instruments/hwc_names.hpp
The testing I needed to do was reduce a testcase for GCC where GCC had an internal compiler error due to -flto usage.
Hi @pinskia
Could you please share the command used to compile the library ?
It doesn't matter: your code is wrong. You need to include the relevant header before using those types. That's how C++ works. Maybe you've got away with it until now with some compilers, but the code is still wrong.
This is documented as a change that might be needed when using GCC 15: https://gcc.gnu.org/gcc-15/porting_to.html#header-dep-changes
But the bottom line is you need to include the right header for anything in the C++ standard library that you rely on.
Hi @jwakely
Many thanks for raising this, we'll have a look at it and fix it
Hi @pinskia
Since GCC15 has not yet been released I'm struggling to reproduce the problem. I'm building ACL main branch with GCC 15.0.0 20240514 (experimental)
and I can't see the errors mentioned above.

The relevant change was committed to GCC trunk on 2024-08-01 so this build won't have it.
There are RPMs of a recent gcc 15 at https://copr.fedorainfracloud.org/coprs/jwakely/gcc-latest/ or you could use the scripts at https://github.com/jwakely/pkg-gcc-latest/ to build a .deb
(I only provide a pre-built .deb
for x86_64 not aarch64).
With GCC 15, the build fails due to missing cstdint include. GCC 15 removed some extra includes in the standard headers and caused the issue. See https://gcc.gnu.org/gcc-15/porting_to.html for more information.
GCC 15 output:
