Problem with Windows build

[SergeyPalamarchuk]

Hello. I'm trying to build rust-zmq on Windows platform, but I'd collided with problem on link stage. I was set enviroment varible LIBZMQ_PREFIX, as discribed in guide. linker can't find external link _ZN18build_script_build4main. Is anybody know that problem? Maby the reason in version libzmq? Then which is version libzmq I must use?

[rotty]

Could you paste the exact steps you took, and include the output of the tools? rust-zmq's appveyor build is working, so maybe you can take inspiration from its build script.

I just got a similar (-ish) linker error when cargo tried to run the zmq build script. The linker error says the __imp_zmq_has symbol isn't found.

This is on a windows 10 machine running the 0b72d48f8 2018-04-10 nightly. ZeroMQ 4.0.4 is installed on my machine.

I ran into the same problem today:

error LNK2019: unresolved external symbol __imp_zmq_has referenced in function _ZN18build_script_build4main17h1f67e42f1e4bb592E

The appveyor script installs zeromq from source for version 4.2.0, but the zeromq Windows binary page stopped updating after 4.0.4. Instead of trying to compile from source myself I used conda:

conda create -n rust-zmq
activate rust-zmq
conda install zeromq
SET LIBZMQ_PREFIX=C:\Users\dg\Miniconda\envs\rust-zmq\Library\
cargo clean
cargo build

(I think I also had to rename a couple files C:\Users\dg\Miniconda\envs\rust-zmq\Library\ from libzmq.lib to zmq.lib, etc)

[rotty]

Ok, so this is more of a documentation issue -- we should document more clearly that Windows users need to build libzmq from source. Once the documentation is updated, this issue can be closed, I think.

[oblique]

I believe it will be simpler if zmq-sys actually compiles zeromq and statically links it. This is what libz-sys, curl-sys and many other crates *-sys do.

[zachlute]

FWIW, I just put up PR #239 to do the build and link on Windows. You still have to install CMake yourself, but it should handle everything else. I don't know how active this project is at this point, but I'm open to input.

Hi there, see related comment in #241.

We use the latest version of libzmq (v4.3.2), which I compiled with Visual Stuio 2017 using the CMake -> Install -> ZeroMQ menu option. I also copied the static lib from libzmq-mt-s-4_3_2.lib to zmq.lib in the lib folder.

I tried to compile branch https://github.com/oblique/rust-zmq/tree/build-zmq, but got some errors, which is the similar to what I get when compiling from master at https://github.com/erickt/rust-zmq

@hansieodendaal You need to recompile libzmq with /GL- C++ flag.

For more info check https://github.com/rust-lang/rust/issues/26003 and MSVC's whole program optimization.

[hansieodendaal]

@oblique, thank you for your response. I cannot find such an option in the CMake files generated by Visual Studio when I open the libzmq folder. It seems that is only available if a project solution is used. My CMakeCache.txt file.

[hansieodendaal]

See PR #249 for dynamic linking of ZeroMQ. Also added basic installation instructions.

[rotty]

I think the Windows issues should now all be addressed by PR #267 and #249.
