Pkg.test("Cairo") fails for me

[ranjanan]

Since build is passing, I must be doing something wrong. Help please!

I just ran into this myself. A Pkg.build("Cairo") fixed it.

[colbec]

I also have the problem "ERROR: LoadError: UndefVarError: _jl_libcairo not defined". OP reports from Mac, I am on Linux. I have done Pkg.checkout("Cairo") followed by Pkg.build("Cairo"), but no difference. The suggestion in #149 to remove Cairo installed in my system would be severe requiring ~600 other applications to be removed.

I believe this issue may be responsible for the failure to test of ImageView which @timholy tried to help me with in julia-users.

Is there a file at Pkg.dir("Cairo","deps","deps.jl") ? If so, what does it say?

[colbec]

File /home/colin/.julia/v0.6/Cairo/deps/deps.jl says:

# This is an auto-generated file; do not edit

# Pre-hooks

# Macro to load a library
macro checked_lib(libname, path)
    ((VERSION >= v"0.4.0-dev+3844" ? Base.Libdl.dlopen_e : Base.dlopen_e)(path)
    quote const $(esc(libname)) = $path end
end

# Load dependencies

# Load-hooks

I have been checking file Cairo/deps/build.jl, and note that section "System Package Managers" contains a reference to Zypper, but previous experience has indicated that the earlier reference to an existing but truncated AptGet might get preference on my system. If I were to move the Zypper entry to precede the AptGet would that ensure that AptGet entry would be ignored?

I have also been checking the format of the deps aliases for minor differences but all looks ok so far.

[timholy]

For comparison, on mine the crucial section looks like this:

# Load dependencies
@checked_lib _jl_libgobject "/usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0"
@checked_lib _jl_libpango "/usr/lib/x86_64-linux-gnu/libpango-1.0.so.0"
@checked_lib _jl_libpangocairo "/usr/lib/x86_64-linux-gnu/libpangocairo-1.0.so.0"
@checked_lib _jl_libcairo "/usr/lib/x86_64-linux-gnu/libcairo.so.2"

[tkelman]

What is BinDeps.has_apt ? ref JuliaPackaging/BinDeps.jl@89d4d8d

[colbec]

julia> using BinDeps

julia> BinDeps.has_apt
false

Edit: as a side note, calling apt-get -v simply as a test triggers the odd appearance of the openSUSE package manager GUI, which is such a curious oddity on openSUSE.

[tkelman]

Okay then that old issue with BinDeps thinking opensuse has apt-get should be resolved. If you comment out

Cairo.jl/deps/build.jl

Lines 75 to 84 in 18c5638

	provides(Zypper,
	@compat Dict(
	"libcairo" => cairo,
	"libfontconfig" => fontconfig,
	"libpango-1.0" => [pango,pangocairo],
	"libglib-2.0" => gobject,
	"libpng12" => libpng,
	"libpixman-1" => pixman,
	"gettext" => gettext
	))

and do Pkg.build("Cairo"), it should build a local copy from source.

[colbec]

OK so did the following:
Commented out the Zypper section as instructed.
Pkg.rm("Cairo") twice, Pkg.add("Cairo"), Pkg.build("Cairo") => build successful but test still fails as above.
Did rm(Pkg.dir("Cairo","deps","usr"); recursive=true) and rm(Pkg.dir("Cairo","deps","src"); recursive=true) then rebuild but again build successful but tests fail same error.
File /home/colin/.julia/v0.6/Cairo/deps/deps.jl no change from above.

[tkelman]

I did not say to Pkg.rm. That probably removed the modifications to the build script.

[colbec]

Oh dear then that is very strange. I go back to my cached Cairo files and find that the modifications I made are still in place. I will start again.

[colbec]

Nope, can't seem to get it. Wiped all traces of Cairo from julia and added it back, . Modified the build.jl file and rebuilt. Still the same error. Changed from block comment to series of single line comments to see if I had the block comment wrong but no I had it right (and build complained once when I had the syntax wrong, so we are looking at the same file), build is fine (and goes very quickly) but test still not cooperating.

[tkelman]

alright then it sounds like this requires trying to debug why bindeps isn't writing any results. I don't have many great suggestions for how to go about that other than adding a bunch of @show calls in various different BinDeps functions.

[colbec]

@tkelman I found the output from the BinDeps.debug("Cairo") quite interesting.
It may not be writing anything because it is satisfied from the system sources?
