Hi, I'm having trouble building the project under Arch Linux:

# git clone python-seabreeze
# cd python-seabreeze
python setup.py build >>file.txt 2>&1

file.txt is attached

The first compile error is:

gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -march=x86-64 -mtune=generic -O3 -pipe -fno-plt -fno-semantic-interposition -march=x86-64 -mtune=generic -O3 -pipe -fno-plt -march=x86-64 -mtune=generic -O3 -pipe -fno-plt -fPIC -I/usr/include/libusb-1.0 -Isrc/libseabreeze/include -I/usr/include/python3.9 -c src/libseabreeze/src/api/seabreezeapi/DHCPServerFeatureAdapter.cpp -o build/temp.linux-x86_64-3.9/src/libseabreeze/src/api/seabreezeapi/DHCPServerFeatureAdapter.o

Any ideas?

Hi @greyltc

What's your gcc version and what's your Cython version?
I will try to reproduce this error on my machine.

Cheers,
Andreas 😃

Hi @greyltc

With gcc-11 I get the same error as you reported.
But seabreeze builds fine on ArchLinux using gcc-10.

$ gcc --version
gcc (Arch Linux 10.3.0-2) 10.3.0

If you could work out what compiler flag changes or code changes would be required to support older and newer versions of gcc (see: https://gcc.gnu.org/gcc-11/changes.html) that would be great.
I would suggest opening a PR and I could give some guidance in there on how to either implement the compiler flag changes dependent on gcc version or how to make the necessary code changes.

Let me know what you think,
Cheers,
Andreas 😃
