compilation of FastLAS2

[dio4ev]

Hi!

I would like to compile FastLAS2 on my machine, but get the following error:

$ make                                                                                                                                                                                                                                                                            [dcefbc9]

Do you know how I can fix that?

Thanks!

Hi,

Do you have bison installed? I've never come across this error before, and can't reproduce it. But the parser depends on bison (although I'd have thought that cmake would have complained if you didn't have it).

[dio4ev]

Yes bison is installed. I have no clue what causes this error. Do you have another idea?

[marklaw]

No. Are you able to build other things in CMake?

I've just made a simple Dockerfile with all the FastLAS dependencies, installing on a fresh (dockerised) instance of Ubuntu 20.04, and it builds fine. The Dockerfile is below. Could you try running each of the steps in the Dockerfile?

FROM ubuntu:20.04

ENV DEBIAN_FRONTEND=noninteractive

RUN apt-get update
RUN apt-get -y install git cmake gringo g++ build-essential flex bison
RUN apt-get -y install libboost-dev libboost-program-options-dev
RUN git clone https://github.com/spike-imperial/FastLAS
WORKDIR FastLAS/FastLAS2/implementation

RUN cmake CMakeLists.txt
RUN make -j8

[dio4ev]

Yes, until now I never had any problems with CMake.

Hmmm strange...the Dockerfile builds without errors and I also checked that I have all the listed dependencies installed on my system. I am using Arch Linux.

Ah, well I've only ever tested FastLAS on Ubuntu. I've had a quick look and found this:

Apparently -o3 should be -O3. It seems Ubuntu and macOS c++ compilers are more tolerant and allow -o3 too. Could you try changing the flag in CMakeLists.txt? If it works, please let me know and I'll update CMakeLists.txt. If this is the issue, I'm sorry for the time it's cost you.

I also looked through stackoverflow, but didn't find this thread :) Apparently, this solves the problem with parser.cpp.

But now I get a lot errors with Solve.cpp -> 0

[marklaw]

It looks like adding #include <string> to the headers that it is complaining about should fix that. If you let me know which headers you have to add it to, I'll update the version in the repo so that people don't have the same issue on Arch in the future.

[dio4ev]

I thought it is easier to just fork and open a pull request :)

At least for me, the changes in the pull request fix all problems.

Thanks!

Thank you!
