Problem with compiler on Linux

[Elendurwen]

Hi,

I had argos3 installed by someone else on a Redhat-based computer cluster. They compiled and installed argos and you can run argos3 -q all without a problem. You can also run cmake for an argos3-dependant example program, but then the actual compilation fails. I think the g++ is of a wrong version, but it might be something else. Does anyone have any idea or has seen this issue before? This is my output:

Edit: I changed the cmake line to

Code: Select all

cmake -DCMAKE_CXX_COMPILER=/local/software/gcc/4.8.1/bin/c++

to assure I have the right compiler version, but it is still not properly recognised, it finds:

Code: Select all

-- The C compiler identification is GNU 4.4.6 -- The CXX compiler identification is GNU 4.8.1

And I still get a similar error when compiling an argos3-dependant program:

Code: Select all

This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

Another edit: I found the higher version of the C compiler as well, so now I get output:

Code: Select all

-- The C compiler identification is GNU 4.8.1 -- The CXX compiler identification is GNU 4.8.1 -- Check for working C compiler: /local/software/gcc/4.8.1/bin/gcc -- Check for working C compiler: /local/software/gcc/4.8.1/bin/gcc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working CXX compiler: /local/software/gcc/4.8.1/bin/c++ -- Check for working CXX compiler: /local/software/gcc/4.8.1/bin/c++ -- works

However, I still have the same problem during compilation of my program

I managed to fix my problem by running the cmake first, then editing the build/CMakeCache.txt, changing the line:

Code: Select all

CMAKE_CXX_FLAGS:STRING=-std=c++11

Then running make builds fine. I am not sure if somehow this could have been done better by passing a parameter to cmake though, to make it more automatic.

Hi,

Sorry for the late reply, but the email notification of the forum seems not working properly.

I fixed this problem before Christmas. There was a little issue in entity.h. To the best of my knowledge, updating Argos and getting the latest version of the examples should be enough to fix the issue.

What version of Argos did you use?

Cheers,
Carlo

[Elendurwen]

Hi Carlo,

the version on that system is 3.0.0-beta21. It was installed shortly before Christmas I believe.

Best,
Lenka

[pincy]

There's a new one after that, beta22

[Elendurwen]

Ok, I'll ask them about updating then, thanks. Must have just missed the new version by days!
