BinDeps.jl finding system Python

Hi Robin,

We are fussing with build.jl, because we don't want to use system Python when installing lcm.

We came onto this because we would like to use python provided by .julia/v0.5/Conda. I think this is not happening. The possibly offending line above is grabbing system python via BinDeps.library_dependency.

please see output from @pvazteixeira below...

Does LCMCore still need Python?

Curious, is Python still needed for LCMCore? I know it was a while back but thought it was removed.

It seems to still be in the deps though: https://github.com/JuliaRobotics/LCMCore.jl/blob/master/deps/build.jl#L24

Broken on 0.6 due to `using Dates`

Tricky glib find on Ubuntu 18.04, Pkg.build("LCMCore") fails

Hi,

We had a little trouble with getting LCMCore to buildon 18.04. Turns out it was a simple fix:

sudo apt-get install libglib2.0-dev

Not sure if the dev package is needed, but that worked for me.

Problem building LCMCore from separate project

After #64, add LCMCore in a fresh project results in

ERROR: LoadError: SystemError: opening file "/Users/tkoolen/.julia/packages/LCMCore/6Feiw/deps/Project.toml": Permission denied

This is because deps/Project.toml is read-only, like every file unpacked from an added package, and write access to Project.toml is required to run update when the deps project is instantiated when there's no Manifest.toml.

Memory leak in event handling of readlog.jl

Right now there's no call to liblcm implementation of lcm_eventlog_free_event .

I've currently manually implemented it as:

function lcm_event_destroy(event::Ptr{LCMCore.lcm_eventlog_event_t})
    ccall(
    (:lcm_eventlog_free_event, LCMCore.liblcm),
    Cvoid,
    (Ptr{LCMCore.lcm_eventlog_event_t}, ),
    event
    )
end

But otherwise, when iterating event by event through a log file, the allocated memory is never cleared.

New release

We should release a new version with the updated LCMType interface. @tkoolen the old API of defining fingerprint(), resize!(), etc. still works, right? So I think this can be a patch release rather than a minor version.

Unsafe arrays change seems to break encode/decode in v0.5.2

When I use LCMCore with the latest code and I use the log playback, it throws an error when decoding the UInt array:

ERROR: LoadError: MethodError: no method matching decode(::UnsafeArrays.UnsafeArray{UInt8,1}, ::Type{brookstone_supertype_t})
Closest candidates are:
  decode(::Array{UInt8,1}, ::Type{T<:LCMType}) where T<:LCMType at /home/gearsad/.julia/dev/LCMCore/src/lcmtype.jl:355
Stacktrace:

 [3] top-level scope at ./none:0
 [4] include_string(::Module, ::String, ::String) at ./loading.jl:1005
...

Ran the tests and they pass. I've jumped back to v0.5.1 and the issue goes away.

I'll try take a look this afternoon, but wanted to check if this rings any bells? It seems to be related to the new UnsafeArrays code.

python was not found in the pkg-config search path

The build fails on ArchLinux :(
I get

Package python was not found in the pkg-config search path.
Perhaps you should add the directory containing `python.pc'
to the PKG_CONFIG_PATH environment variable
No package 'python' found

It seems that pkg-config does not work for python but works for python3 and python2.

$ pkg-config --cflags python 
Package python was not found in the pkg-config search path.
Perhaps you should add the directory containing `python.pc'
to the PKG_CONFIG_PATH environment variable
No package 'python' found
$ pkg-config --cflags python3
-I/usr/include/python3.6m
$ pkg-config --cflags python2
-I/usr/include/python2.7

If I remove the validator for python then the build completes successfully.
Would it be appropriate to check for python, python2 and python3 in the validator and return true if at least one works ?

Ubuntu 16.04 compiling issues with hamcrest

Hi @rdeits ,

Have you maybe seen an LCM compile issue with the hamcrest dependency? As far as I can trace it maybe an openjdk-7or 8 issue. Are you on openjdk-6 or later?

EDIT: I should add, I tried this for several lcm-proj/lcm master branches from March 2017 through August, but they all have the same issue.

Please see the issue I posted at lcm-proj/lcm#192.

This is what I get for a new LCMCore.jl install.

Access to undefined reference when resizing vector-of-vectors

I have the following two message types:

mutable struct polynomial_t <: LCMType
    timestamp::Int64
    num_coefficients::Int32
    coefficients::Vector{Float64}
end

@lcmtypesetup(polynomial_t,
    (coefficients, 1) => num_coefficients,
)

mutable struct polynomial_matrix_t <: LCMType
    timestamp::Int64
    rows::Int32
    cols::Int32
    polynomials::Vector{Vector{polynomial_t}}
end

@lcmtypesetup(polynomial_matrix_t,
    (polynomials, 1) => rows,
    (polynomials, 2) => cols
)

If I try to resize a polynomial_matrix_t as follows:

m = LCMPolynomials.polynomial_matrix_t()
m.rows = 1
m.cols = 1
LCMCore.resize!(m)

then I get this error:
