What Compiler and options used for Raspian build

gmh

Hello, we're doing some experiments on a Raspberry Pi 4 (Raspbian GNU/Linux 10 (buster)) Using the ICE C++11 bindings with the g++ 8.3 compiler delivered with the OS. We're having occasional problems with ICE ( libzeroc-ice3.7:armhf package ). It behaves like an ABI issue, although I suppose it could be either general compiler options or the C++ ABI that changed at g++-7. Can you tell me what compiler version and compile options were used for this package?

Hi Greg,

We use the default OS compiler g++ 8.3, are you installing zeroc-ice packages from the debian repository or from a different source?
Do you have any more info about the failures?
You can try running the 3.7 test suite against the binary distribution to check if everything works

git clone git@github.com:zeroc-ice/ice.git
cd ice
make ICE_BIN_DIST=all CONFIGS=cpp11-shared V=1
ICE_BIN_DIST=all python allTests.py --config=cpp11-shared --all

We regularly run all tests on debian armhf and arm64 platforms and are not aware of any issues that affect the C++11 mapping, there is a known issue that affects the C++ 98 mapping but shouldn't matter for your case as you are using the C++11 mapping.

Thanks. We'll keep investigating. When we build our application with -mcpu=cortex-a72, we have problems that would be explained by an ABI mismatch. Using -march=armv6+fp avoids the issue. I haven't seen anything to indicate that there are ABI differences by specifying a different cpu.
