error when make converter folder

[whatlas]

try to compile MNN on my x64 PC with WSL environment. The Ubuntu version is 18.04 from Microsoft store, with libprotobuf 3.0.0.9 installed by apt-get.
this script https://github.com/alibaba/MNN/blob/master/doc/Install_EN.md can be compiled without any error. but when I try to compile converter folder, errors occur like

then I add #include <functional> to tfUtils.hpp to fix this error. but got this

can I get any help ? seems its a protobuf problem but I cannot get the reason.

[czy2014hust]

Could you upgrade protobuf? Probably protobuf version result in this error, you can try protobuf version@3.6.

[li-qing]

it's not a protobuf problem. we include a copy of protobuf in 3rd_party folder, and which is used in generating headers from protos.

run schema/generate.sh before building converter, and make sure no error occurs.

I run this script and got these errors

./schema/generate.sh: line 9: pushd: ../3rd_party/flatbuffers: No such file or directory
./schema/generate.sh: line 17: popd: directory stack empty
*** cleaning up ***
*** generating fbs under default ***
find: ‘../default/*.fbs’: No such file or directory
../../3rd_party/flatbuffers/tmp/flatc: error: missing input files

but I can still compile MNN root folder without any problem, this issue only occurs in converter folder

[li-qing]

I see ...

please follow install.md's guide -- "cd schema && ./generate.sh && cd ..",

not "./schema/generate.sh", so that path error will be fixed.

consider to make the shell compatible later.

thks, now cmake in root folder makes no misktake ,BUT the converter folder cannot be compiled yet, just as i wrote in this issue, MNN/tools/converter/source/tensorflow/SplitTf.cpp:106:53: error: no match for ‘operator[]’ (operand types are ‘const google::protobuf::RepeatedField<int>’ and ‘int’), it looks definitely like a protobuf problem

[whatlas]

solved this problem by changing file tools\converter\source\tensorflow\SplitTf.cpp line 106

splitvParam->axis = value.tensor().int_val()[0];

to

splitvParam->axis = value.tensor().int_val(0);

now everything works.
