Build error (on Linux Mint 18.1): 'PTXLexer' is not a member of 'parser

[eyalroz]

I'm trying to build gpuocelot on a Linux Mint 18.1 system (it's based on Ubuntu 16.04 Xenial Xerus). After following the clone and submodule init instructions, I ran:
./build.py -j 4 -p ~/opt/gpuocelot -i
in the gpuocelot source directory, and after some successful compilations I get:

In file included from ocelot/ocelot/parser/interface/PTXLexer.h:11:0,

What should I do?

[wanglu1991]

Same problem.Have you found a solution?

[eyalroz]

No, but to be honest I didn't really invest time in finding a solution. if you do find something, let me know (or just write me regardless - looks like we might have some common interests.)

[hemangandhi]

Any updates? I'm still getting this issue... I'm thinking that the file outputted by bison is somehow Kaput - it lacks the includes that are on the top of ptxgrammar.yy.

[eyalroz]

No updates from me, but again - I haven't looked into this further.

[hemangandhi]

I think this may fix the issue: https://github.com/hemangandhi/gpuocelot/tree/fix-parser

It seems two-fold: firstly, the generated header didn't include some required types.
Then, including said types causes a circular dependency.

I don't think my fix is the best, but it's a hack that seems to work, at least for the compilation of Module.cpp. Let me know if you think it's PR-worthy. (Now I'm getting a separate boost issue that I'll figure out. Might be me being dumb about library versions - I haven't worked with boost enough.)

@hemangandhi : With the branch you linked to, I get different errors. Would you like me to open a new bug on your issue page, or post them here?

[hemangandhi]

I'm not sure what collaborators would prefer... but here is easier for me (also because I'm getting an issue that might suggest that my "fix" is incomplete - TOKEN_TYPE not defined in PTXLexer).

I'll definitely work on this until this builds. Thanks for checking!
