Build fails

[alipourm]

Build fails. It seems that it is related to solidity parser.

/mainsol.py solidity.y
bison -d pt_solidity.y -o pt_solidity.tab.cc -v -g
pt_solidity.y:213.9-15: syntax error, unexpected identifier, expecting string
make[1]: *** [pt_solidity.tab.cc] Error 1
make: *** [TARGET] Error 2

I have encountered the same problem on MacOS, and I solved it by installing the latest version of bison.

[alipourm]

bison is already the latest version.

$ brew install bison Warning: bison 3.3.2 is already installed and up-to-date

[chenzimin]

You have to, if you haven't done it already, force link bison (in MacOS at least), otherwise it still uses the older version of bison:

brew link bison --force

and export the bin path to bison:

'export PATH="/usr/local/opt/bison/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile

You can check the bison version by:

bison -V

Thanks! It worked.

I get this error when building. Can anyone help me with this? I am running the latest version of bison and python 2.7

It seems '' doesn't exist on MacOS.

A replacement is to use #include <mach/error.h> on Mac OS.

My approach is to remove the include statement, since it is not used in solidity.l. After removing it, my build succeeded.
