[julia-users] installing c library using BinDeps

[Martin Kuzma]

Hi, I am trying to install c library using BinDeps. But I am getting error: 
ERROR: LoadError: Could not load library triangle. Try running Pkg.build() 
to install missing dependencies!

I followed its github manual:

*Directory structure:*

deps/
  build.jl
  builds/     
    Makefile
    src/        
      triangle.c
      triangle.h
    usr/
      lib/
src/
 test.jl

*The Makefile content:*

SRC = ./../src/
LIB = ./../usr/lib/
BUILD = ./
CC = gcc
CSWITCHES = -O -DLINUX -DANSI_DECLARATORS -fpic
TRILIBDEFS = -DTRILIBRARY

all: $(LIB)triangle.so

$(LIB)triangle.so: $(BUILD)triangle.o
        $(CC) -shared -o $@ $^

$(BUILD)triangle.o: $(SRC)triangle.c $(SRC)triangle.h
        $(CC) $(CSWITCHES) $(TRILIBDEFS) -o $@ -c $(SRC)triangle.c

clean:
        rm -rf $(BUILD)triangle.o 


*build.jl content:*

using BinDeps

@BinDeps.setup
    triangle = library_dependency("triangle", aliases = ["triangle.so"])
    prefix = joinpath(BinDeps.depsdir(triangle), "usr")
    triangle_build = joinpath(BinDeps.depsdir(triangle), "builds")
    provides(SimpleBuild,
       (@build_steps begin
            ChangeDirectory(triangle_build)
             FileRule(joinpath(prefix, "lib", "triangle.so"),
                (@build_steps begin
                    `make`
                    `make clean`
                end))
        end), triangle)
@BinDeps.install

*test.jl content:*

using BinDeps
@BinDeps.load_dependencies

Did anyone have this problem? Basically the make command puts triangle.so 
to the lib folder. But it seems, that julia cant find it.
Thanks for your advices. Martin
