Since commit v3.4.0-rc1~5^2~1 (VS: Add support for selecting the Windows
10 SDK, 2015-09-30) the VS 2015 generator requires a Windows 10 SDK to
be available when CMAKE_SYSTEM_VERSION specifies Windows 10 (e.g. when
building on a Windows 10 host). Howewver, it is possible to install VS
2015 without any Windows 10 SDK. Instead of failing with an error
message about the lack of a Windows 10 SDK, simply tolerate this case
and use the default Windows 8.1 SDK. Since building for Windows Store
still requires the SDK, retain the diagnostic in that case.
In commit v3.4.0-rc1~5^2~1 (VS: Add support for selecting the Windows 10
SDK, 2015-09-30) we added Windows 10 SDK selection choosing the most
recent SDK that is not newer than the target version. This is backward
because it should be up to the application code to not use APIs newer
than the target version. It is up to the build system to provide a SDK
that has at least the APIs expected to be available for the target
version. Furthermore, since the default target version is the host
version of Windows, the old approach breaks when the only SDK available
is for a newer version of Windows.
Fix this by always selecting a Windows 10 SDK if one exists. Use the
SDK for the exact version if is available. Otherwise use the latest
version of the SDK available because that will have at least the APIs
expected for the target version.
Starting with VS 2015 the GenerateDebugInformation build property is an
enumeration (`No`, `Debug`, `DebugFastLink`) instead of a boolean value
(`false`, `true`). For now we simply change to `No` and `Debug` fix
current behavior. Support for `/debug:fastlink` can be added later.
Since commit v3.1.0-rc1~110^2 (Tolerate symlinks during RPATH ordering,
2014-09-09) we call realpath() for every directory ordering constraint
check. On some platforms/filesystems this is slow, so memoize the
result of the call for each directory.
We enforce policy push/pop balance around any scope that pushes/pops a
snapshot. Therefore a snapshot may never reference entries of
PolicyStack that were created in nested scopes. Free storage of
short-lived policy stack entries when they are popped.
Add a method to increment an iterator (follow the "up" pointer) to the
previous level in the stack of scopes and free storage of the top of the
stack if possible. This will allow short-lived scopes to be created and
destroyed by matching Push/Pop pairs without accumulating storage.
Logically the method pushes a nested scope on top of a given scope
because the "up" pointer sequence forms a stack independent of any
other branches of the tree.
Everywhere we use cmMakefile::ScopePushPop to manage variable scopes
also expects policy scopes to be balanced. There is no place that we
use cmMakefile::PolicyPushPop without also using ScopePushPop. Relieve
PolicyPushPop of responsibility for policy scope balance checks by
moving it to ScopePushPop.
The PolicyPushPop constructor arguments and Quiet method were used to
pass non-default arguments to PushPolicy and PopSnapshot, but no clients
use them anymore.
The `PopPolicyBarrier` method is actually responsible for closing any
scope opened by creating a snapshot. Rename it to `PopSnapshot` and add
a comment explaining the purpose of the poilcy-scope-specific part of
the method.
Since commit v3.4.0-rc1~179^2~1 (cmState: Add a VariableScope snapshot
type, 2015-08-23) the snapshot stack may have a VariableScopeType entry.
Skip over these when constructing the call stack, just as we do for
policy scopes. Otherwise we report the command causing the variable
scope to be entered twice (e.g. find_package while loading a package
version file).
This fixes a bug where 64 bit builds with /bigobj incorrectly determined
that the object files were not 64 bit. This manifested itself with
printf type functions showing up as undefined because the leading
underscore was being removed and should not be removed.
Our check of CMAKE_PLATFORM_NO_VERSIONED_SONAME, originally added by
commit v3.1.0-rc1~416^2 (Add basic Android platform module, 2014-06-06),
was dropped accidentally by commit v3.4.0-rc1~250^2~21
(cmGeneratorTarget: Move GetLibraryNames from cmTarget, 2015-08-04).
Restore the check in the new location of the GetLibraryNames method.
Refactoring in commit v3.4.0-rc1~74^2~1 (MSVC: Rewrite manifest file
handling with Makefile and Ninja, 2015-09-15) broke handling of this
option. Fix it and add a test case.
The moved-from location checks for the existence of whether certain
generators are needed for any target in a loop, rather than whether
the current target has an install rule.
This was introduced in commit v3.4.0-rc1~275^2~3 (cmInstallCommand: Move
the SetHaveInstallRule invocation., 2015-07-28). Move the
SetHaveInstallRule call to a more-obvious place where the
cmInstallTargetGenerator is constructed.
Changes in commit v3.4.0-rc1~124^2~1 (cmFindProgramCommand: Re-implement
search using more flexible approach, 2015-09-01) did not preserve the
behavior of looking for the given name with no search path at all.
Fix this and add a test case covering finding an absolute path with
no search directories.
This reverts commit 9a271e1323. The
`-list` option is not documented and may be removed in future Qt
versions. Fixing this correctly will require detecting the availability
of `--list` or `-list` based on the `rcc` version found. For now we
choose to support the documented option that will be supported in future
Qt versions.
Changes in commit v3.4.0-rc1~79^2~1 (CPackDeb: use of libarchive and
removal of fakeroot, 2015-09-11) accidentally set the wrong compression
scheme for the `control.tar.gz` file. Set it explicitly to GZip.
Refactoring in commit v3.4.0-rc1~390^2~1 (cmCTestMultiProcessHandler:
Refactor RUN_SERIAL implementation, 2015-06-01) forgot to update a code
path for cleaning up after a failed RUN_SERIAL test. This causes an
infinite loop after a RUN_SERIAL test fails. Fix it and add a test.
Commit v3.4.0-rc1~494^2~4 (cmMakefile: Add API for elseif to create
backtrace., 2015-05-29) removed the use of cmMakefileCall to push/pop
execution context in favor of a new way to create backtraces.
However, a call to cmMakefile::GetExecutionContext is still invoked to
issue a contextual CMP0054 warning through cmConditionEvaluator. As
the elseif is not part of the call stack, this resulted in trying to
access an empty vector.
Avoid the attempt at getting execution context when evaluating elseif by
constructing a context and backtrace on behalf of the cmConditionEvaluator
in all cases.
