Use of 'strtok_r' fails in Windows about curl-rust HOT 9 CLOSED

The problem is that the gcc version bundled with Rust does not define strtok_r, and the MinGW version does. The solution is to change the installation of Rust to not install the bundled gcc. If you re-run the setup; choose "Change", click the drop down before "Linker and platform libraries" and choose "The entire feature will be unavailable", the compilation should work.

I tracked this down awhile ago and unfortunately the problem is:

• libcurl is compiling with the system gcc and is detecting a newer feature, the strtok_r function.
• When the compiler links the crate, it uses a bundled gcc version
• This bundled gcc version uses its own libraries, which don't have the detected function.

Unfortunately the only fix here is to just delete the bundled linker that comes with Rust (or uncheck the box during the install).

@alexcrichton What is the equivalent to "unchecking the box during install" for installs with rustup?

from curl-rust.

@masaeedu unfortunately I don't know of a great way to do that. My personal way to work around this is to always install the MSVC host toolchain and then target pc-windows-gnu, that way these components aren't picked up

from curl-rust.

@alexcrichton I've also tried the MSVC toolchain, but this package seems to break with that as well, with the following error message:

Couldn't find libcurl from pkgconfig ("MSVC target detected. If you are using the MSVC ABI rust build, please use the GNU ABI build instead."), compiling it from source...

I'm trying to install https://github.com/killercup/cargo-edit, which depends on curl, using cargo install cargo-edit. If I use the GNU toolchain via rustup default stable-gnu, I get the strtok_r issue. If I use the MSVC toolchain via rustup default stable-msvc I get the message I pasted above. Any ideas on how to proceed are greatly appreciated.

@masaeedu that looks more like an informational message than an error maybe? Could you gist the full build log?

from curl-rust.

@alexcrichton Sure. Here you go: https://gist.github.com/masaeedu/475aa03570af8f548430f85652071530

Oh the actual build there is:

curl_setup.h(132): fatal error C1083: Cannot open include file: 'curl/curlbuild.h': No such file or directory

That's building an ancient version of curl-sys though (0.1.*) which has had tons of bug fixes since then. Unfortunately though it doesn't look like you control the version being used :(

I guess cargo-edit's depending on an old version of curl, which in turn pulls in an old version of curl-sys. I'll go file a bug there. Thanks.
