Minimum GCC required?

[IsmailM]

With GCC 4.8.5, I get the following error:

g++ -std=c++14 -ggdb -Wshadow -Wall -pedantic -pipe -O3 -fopenmp -march=native -I ./sparsehash/include/usr/local/include/ -I ./hopscotch-map/include/tsl/ -c gzstream/gzstream.C
g++: error: unrecognized command line option ‘-std=c++14’
make: *** [gzstream.o] Error 1

(Attempting to use -std=c++1y instead causes a different issue (in ReadQueue.cpp))

So what is the min GCC version required?

[FischerJo]

Your attempt with -std=c++1y was the right thing to do. Could you please post the followup error that you got in ReadQueue.cpp?

ReadQueue.cpp:2571:38:   required from here
./hopscotch-map/include/tsl/hopscotch_hash.h:1729:20: warning: declaration of ‘bucket_count’ shadows a member of 'this' [-Wshadow]
make: *** [ReadQueue.o] Error 1
The command '/bin/sh -c make' returned a non-zero code: 2

You can reproduce with the following Dockerfile:

FROM gcc:4.8.5
COPY . /usr/src/fame
WORKDIR /usr/src/fame
RUN sed -i 's/-std=c++14/-std=c++1y/g' Makefile
RUN make
CMD ["./FAME"]

Building the above in the FAME source directory (docker build -t fame .) will show the above error...

On a side note, I was able to use the above Dockerfile with gcc:latest to create a static binary (using -static -static-libgcc -static-libstdc++), which I was then able to use in the host machine (would be nice if these were available in Github releases)

Okay what wonders me the most is that it crashes when there is a warning. Could it be that the compiler is set with a flag that enforces warnings to be treated as errors, e.g. -Werror? Or is there any earlier error message that was not posted here?

I will soon include docker builds into the release of FAME, including your suggestion of a static binary. Thanks for trying it out!
