Overwriting CMAKE_OSX_SYSROOT with an invalid value about ios-cmake HOT 7 CLOSED

And further work is done with CMAKE_OSX_SYSROOT as a path to a file, rather than as the name of the SDK.

In these points:

I think there should be used CMAKE_OSX_SYSROOT_INT.

from ios-cmake.

For what purpose?

After reading the documentation it became clearer:

"Specify the location or name of the macOS platform SDK to be used."

There are some problems with cmake versions above 3.14 that includes the combined builds support that forced me to rewrite the sysroot path.

Is this still an issue fo you? The reasoning being that lots have changed since May and i have made some patches in the last months that might have improved the issue with regards to newer versions of CMake being released.

Sorry for the long delay in answering. Hopefully I can check this out soon in my project.

Nevertheless, I express my gratitude to you for the work done. Sorry I didn't do it right away.

My problem, both earlier and now, is to get exactly the path to the SDK. In my project, I build the Boost library through its build system (b2) and the CMake. CMake should pass the compiler path and flags to the b2. For this reason, a name of the SDK cannot be used.

As a result, both earlier and now, I use CMAKE_OSX_SYSROOT_INT from your ios.toolchain.cmake.

You can see more details in the project repositories.
Explanation and common scripts:

Project repository for the Boost building and CMAKE_OSX_SYSROOT_INT variable usage:
https://github.com/LibCMaker/LibCMaker_Boost/blob/master/cmake/cmr_boost_set_cmake_flags.cmake#L172
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -isysroot ${CMAKE_OSX_SYSROOT_INT}")

But CMAKE_OSX_SYSROOT_INT is a variable for internal use, not documented.

That is, there is a problem with the CMAKE_OSX_SYSROOT variable, but I am using a workaround with undocumented variable CMAKE_OSX_SYSROOT_INT.

I think the problem can be closed by adding documentation for the CMAKE_OSX_SYSROOT_INT variable. And at your discretion, you can change the name of the variable.

This is now "fixed" on dev where the "CMAKE_OSX_SYSROOT" always points to a path in the requested SDK. It is just setting the value more or less based off "CMAKE_OSX_SYSROOT_INT".
