At jl.config: g++: error: libjulia.dll.a: No such file or directory #46

Closed standarddeviant closed 7 years ago

standarddeviant commented 7 years ago

I may have missed something, but when I run jl.config() on Matlab2016A, Windows x86-64, Matlab yields g++: error: libjulia.dll.a: No such file or directory

This seems obvious based on https://github.com/JuliaLang/julia/issues/13337

I have verified that there is not a file there, but other issues seem to have gotten past this point. Apologies if this is redundant, but I searched the issues and didn't see a workaround for a missing libjulia.dll.a

As an aside, mexjulia seems like an intriguing way to wean codebases off of MATLAB in a piecemeal fashion, which is rather exciting.

Here is the full output of jl.config():

The standard julia installer for windows should include a libjulia.dll.a in the lib directory.

Also, it looks like you are using MinGW to build. I have no reason to believe that using it to build mexjulia through the mex command (as jl.config does) shouldn't "just work," but I also haven't tried this myself.

standarddeviant commented 7 years ago

I was looking in the bin directory before. It is included in the lib directory. Apologies for the spam.

@twadleigh Do you typically use MSVC? If so, what version?

twadleigh commented 7 years ago

Ever since I put jl.config together to make the building simpler across platforms I have primarily used MSVC to build mexjulia. In that time I've probably used every version from 2008 to 2017 without any real issues.

By closing this issue, does this mean you got it to build successfully with MinGW? If so, great. If not, let's reopen this and see if we can at least get it to build for you.

I'll also be curious to know if you get the immediate segfaults that other windows users (#39) have reported. I myself haven't been able to duplicate it. An extra data point might at least help narrow down under what conditions it occurs.

twadleigh commented 7 years ago

OK, I think I know what might fix this for building with MinGW. libjulia.dll.a is spelled out as an extra object for linking on the command line vs. what should be the normal thing (adding -ljulia). The reason for that is that -ljulia will cause MSVC to look for something named julia.lib, which, of course, doesn't exist. Hence the hack. MinGW shouldn't have that problem, though.

Getting jl.config to work with both MSVC and MinGW may now mean we have to be able to query which compiler we are using. Which means more hackery and special casing. sigh (Using the mex command to build was supposed to make things simpler. :cry: )

twadleigh commented 7 years ago

It might also be sufficient to list the full path to libjulia.dll.a when attempting to do the link. That would avoid special case hackery if it works.

standarddeviant commented 7 years ago

Your last suggestion is very reasonable - and it worked! I have a few matlab versions on different computers. I'll report back if using the libjulia.dll.a fullpath doesn't work, but I'm closing the issue for now.

I don't have an affinity for MinGW, but it is the "free and click these buttons to get a C/C++ compiler" for matlab since 2016 or so.
