Which version of libfmt is being used?

[cs-sun]

I have tried v4.0.0 and v3.0.0, and both of them cant run properly on example/mnist.

when compiling graphnn with libfmt v3.0.0 got warning:

include/fmt/format.h(2591): warning: statement is unreachable

and while running mnist example later got error:

➜  mnist ✗ make -j
g++ -Wall -O3 -std=c++11 -DUSE_GPU -I/usr/local/cuda/include -I/opt/intel/mkl/include -I../../include -Iinclude -o build/mnist mnist.cpp ../../build/lib/libgnn.a -L../../build/lib -lgnn -lm -L/usr/local/cuda/lib64 -lcudart -lcublas -lcurand -lcusparse -lmkl_rt -lfmt

I'm using v4.0.0.

It seems that you haven't installed the libfmt properly. The message cannot find -lfmt tells that the libfmt library is not in your system path.

I got the same problem. Can you give more details to install libfmt properly?

[Hanjun-Dai]

after cloning the libfmt, do the following: mkdir build cd build make -j sudo make install

you can also install to your local dir when needed.

But I'll try to remove this dependency shortly.

I can run the code correctly.

I've included the core code of libfmt into this project. Now the graphnn library is self-contained, and no separate dependency of libfmt is needed.
