Hi again, I think I figured it out now. The variable I need to use is CMAKE_STAGING_PREFIX, which is used for cross-compiling environment such as this package. I tested and does exactly what I needed.

Thanks anyway!

Hi guys, First of all, thank you very much for putting together this wrapper package. Is simply amazing and makes things so easy to use!

However I'm having trouble setting CMAKE_INSTALL_PREFIX in my builds. When I set this variable, the CMAKE_SYSTEM_PREFIX_PATH ends up wrong and things like find_path() stop working. For example:

No install prefix provided, default is /usr/x86_64-w64-mingw32:

CMAKE_SYSTEM_PREFIX_PATH is /usr;/usr/x86_64-w64-mingw32;/

Install prefix provided -DCMAKE_INSTALL_PREFIX=/tmp/install:

CMAKE_SYSTEM_PREFIX_PATH is /usr;/tmp/install;/

As you can see, the system path /usr/x86_64-w64-mingw32 is not present anymore and of course find_path() doesn't find things correctly.

I noticed that in other environments such as MSYS2 or standard cmake, things work as expected. For example in standard cmake in ArchLinux:

No install prefix provided, default: /usr/local:


Install prefix provided -DCMAKE_INSTALL_PREFIX=/tmp/install:


As you can see, the system path /usr/local is actually duplicated, therefore if you change the default CMAKE_INSTALL_PREFIX it doesn't break.

Now, I noticed that in the mingw-w64-cmake package, the wrapper actually passes CMAKE_INSTALL_PREFIX=${mingw_prefix} and providing it externally actually overrides it. Therefore, explaining the issue.

With all that, I would kindly like to ask how I'm supposed to set a custom CMAKE_INSTALL_PREFIX of my own with this mingw-w64-cmake package?

Is this a short-coming of the wrapper? Thanks!

I just tested, and it fixes it.

I think it appears only in C++ and when using a cmake config file (FooConfig.cmake used by find_package(Foo))

the problem appears with jsoncpp for example:

$ aurman -S --noconfirm --noedit mingw-w64-jsoncpp

$ git clone --depth 1 && cd pkgtest && x86_64-w64-mingw32-cmake . && make

we can see that ./CMakeFiles/t_jsoncpp.dir/includes_CXX.rsp contains "-isystem /usr/x86_64-w64-mingw32/include"

interesting thing is that with cmake 3.13.4 the includes_CXX.rsp is not used/present

I created an issue:

xantares commented on 2019-03-26 19:59

yeah, on simple stuff it goes fine here too.

I've got it with:

compiling t_agrum

Martchus commented on 2019-03-26 19:56

Do you have a simple example? I've just tried with a simple project file and couldn't reproduce it. That's currently preventing me from filing an issue.

By the way, if you're wondering why I haven't updated Qt to 5.12.2 yet - that issue delayed my tests.

xantares commented on 2019-03-26 19:47

yes, this is bad I've got it too.

if you do file an issue can you post its link here too so I can follow ?

Martchus commented on 2019-03-26 19:40

I'm going to file an issue. I reproduce this by building one of my projects, e.g. Syncthing Tray. When I downgrade the CMake version installed in the systemd container and re-run CMake it works again. So it is quite likely that a change in CMake is responsible. Someone on the #cmake channel on free node also told me that there were changes regarding implicit include directories made.

xantares commented on 2019-03-26 19:33

how do i reproduce exactly ?

is there a bug report somewhere ?
