Bug ID: 400393
Summary: When using cargo for compilation, the C++ standard lib
is incorrect on Windows when linking but not
compiling.
Product: rust-qt-binding-generator
Version: unspecified
Platform: MS Windows
OS: MS Windows
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: j...@vandenoever.info
Reporter: jacobj...@gmail.com
Target Milestone: ---
SUMMARY
When using cargo for compilation, such as with the "qt_quick_cargo" template,
if the C++ library is already compiled, then rust-qt-bindings-generator will
output linker information, including the standard library stdc++. When
compiling with stdc++, this fails because stdc++.lib does not exist.
The relevant code is here:
https://github.com/KDE/rust-qt-binding-generator/blob/master/src/build.rs#L241
rust-qt-bindings-generator should replicate the behavior of the cc crate, which
can be found here:
https://github.com/alexcrichton/cc-rs/blob/master/src/lib.rs#L928
STEPS TO REPRODUCE
1. Compile the qt_quick_cargo template
2. Change main.rs to trigger a recompile of the rust code but not the C++
library
3. Recompile
OBSERVED RESULT
MSVC fails to link stdc++
EXPECTED RESULT
It should not try to link to stdc++
