how should we install openfst properly to let pynini recognize the library?

Dear Kyle,

Thanks for your previous reply (long time ago) on my issue! I realized that reply a while ago on new version of pynini and playing with it. But I found problem when compiling it.

I compiled an openfst first (version 1.7.1) using below command:

cd tools/openfst-1.7.1/
./configure --enable-static=no --enable-grm
make -j 4

then go to pynini folder at same path (version 2.0.6) and compile it but then it outputted some error about ld calling:

building 'pywrapfst' extension

/usr/bin/ld: cannot find -lfstscript
collect2: error: ld returned 1 exit status
error: command 'x86_64-linux-gnu-g++' failed with exit status 1

so I guess the problem is the way of my compiling openfst, making it not "global" enough. Any ideas on how to properly compiling openfst for it? Thanks!

You've compiled OpenFst, but not yet installed it. In tools/openfst-1.7.1 you have also issue sudo make -j4 install to install it.

Tried and worked :joy: thanks Kyle
