Build Error

[victorstewart]

building on Clear Linux (6.6) with GCC 13.2.1 with this command python3 ./build/fbcode_builder/getdeps.py --allow-system-packages build katran and got this error:

/tmp/fbcode_builder_getdeps-ZrootZkatranZbuildZfbcode_builder-root/repos/github.com-facebookincubator-katran.git/katran/lib/BpfLoader.cpp: In function ‘std::string katran::{anonymous}::libBpfErrMsg(int)’: /tmp/fbcode_builder_getdeps-ZrootZkatranZbuildZfbcode_builder-root/repos/github.com-facebookincubator-katran.git/katran/lib/BpfLoader.cpp:46:25: error: variable ‘std::array<char, 128> buf’ has initializer but incomplete type 46 | std::array<char, 128> buf{}; | ^~~ [17/80] Building CXX object katran/lib/CMakeFiles/katranlb.dir/KatranLb.cpp.o

so i just manually edited BpfLoader.cpp to add #include <array> at the top, then it built successfully.

The above solution did not work for me, when i used ./build.sh but it works with the python script, so something is off.
