bd11de0 Makefile: Allow "gmake target1 target2 -j" (#14312)
2013-12-20 09:41:32 -05:00
Brad King bd11de0857 Makefile: Allow "gmake target1 target2 -j" (#14312)
Add the .NOTPARALLEL target to each local Makefile command-line
interface entry point file so that even with -j we launch only
one "make -f Makefile2" at a time.  The actual build rules
in Makefile2 and lower will still run in parallel.

Do not add .NOTPARALLEL for Borland or Watcom make tools because
they do not tolerate it.  Other make tools that do not understand
.NOTPARALLEL will not be hurt.

Stephen Kelly 97fae68b81 Remove INTERFACE build targets.
Commit b04f3b9a (Create make rules for INTERFACE_LIBRARY
targets., 2013-08-21) extended the makefile generator to create
build targets for INTERFACE_LIBRARY targets. No other generators
were extended with this feature.

This conflicts with the feature of whitelisting of target properties
read from INTERFACE_LIBRARY targets. The INTERFACE_* properties
of the INTERFACE_LIBRARY may legitimately contain TARGET_PROPERTY
generator expressions for reading properties from the 'head target'.
The 'head target' would be the INTERFACE_LIBRARY itself when creating
the build rules for it, which means that non-whitelisted properties
would be read.

02a545c Don't generate subdir convenience rules for IMPORTED targets.
2013-12-02 12:07:41 -05:00
Stephen Kelly 02a545c534 Don't generate subdir convenience rules for IMPORTED targets.
This was missing from commit c34968a9 (Port some of the generator
API to cmGeneratorTarget., 2012-10-10). The generator targets
stored with the cmMakefile include IMPORTED targets, unlike the
accessor for resgular targets. Before this patch, rules would
be generated for Qt5::Core for example, which result in broken
makefiles.

Stephen Kelly 0bfcb450e6 INTERFACE_LIBRARY: Avoid codepaths which set unneeded properties.
As an INTERFACE_LIBRARY has no direct link dependencies, we can
short-circuit in cmGeneratorExpressionEvaluator and
in cmGlobalGenerator::CheckLocalGenerators.

As they do not generate any output directly, any generate- or install-
related code acn also be short-circuited. Many of the local generators
already do this.

Because only INTERFACE related properties make sense on INTERFACE_LIBRARY
targets, avoid setting other properties, for example via defaults.

Stephen Kelly c34968a9aa Port some of the generator API to cmGeneratorTarget.
Just enough to reach the BuildMacContentDirectory method and the
NeedRelinkBeforeInstall methods.

In the future, those methods can be moved to cmGeneratorTarget.

Brad King 684063c036 Refactor tool selection for edit_cache (#14544)
Refactor edit_cache tool selection to ask each global generator for its
preference.  Teach the Ninja generator to always use cmake-gui because
Ninja by design cannot run interactive terminal dialogs like ccmake.
Teach the Makefile generator to use cmake-gui when also using an "extra"
generator whose IDE has no terminal to run ccmake, and otherwise fall
back to CMAKE_EDIT_COMMAND selection for normal Makefile build systems.

Stephen Kelly b04f3b9a2a Create make rules for INTERFACE_LIBRARY targets.
The result is that the depends of the target are created.

So,

 add_library(somelib foo.cpp)
 add_library(anotherlib EXCLUDE_FROM_ALL foo.cpp)
 add_library(extra EXCLUDE_FROM_ALL foo.cpp)
 target_link_libraries(anotherlib extra)

 add_library(iface INTERFACE)
 target_link_libraries(iface INTERFACE anotherlib)

Executing 'make iface' will result in the anotherlib and extra targets
being made.

Adding a regular executable to the INTERFACE of an INTERFACE_LIBRARY
will not result in the executable being built with 'make iface' because
of the logic in cmComputeTargetDepends::AddTargetDepend.

So far, this is implemented only for the Makefile generator. Other
generators will follow if this feature is possible for them.

Make INTERFACE_LIBRARY targets part of the all target by default.
Test this by building the all target and making the expected library
EXCLUDE_FROM_ALL.

in c++ by cmake.

Brad King 4bb6e24809 VS,Xcode: Drop incorrect legacy dependency trace (#14291)
Drop the "vsProjectFile" argument from cmTarget::TraceDependencies.  It
appears to be the modern equivalent to a hunk added in commit ba68f771
(...added new custom command support, 2003-06-03):

 +  name = libName;
 +  name += ".dsp.cmake";
 +  srcFilesToProcess.push(name);

but was broken by refactoring at some point.  The current behavior tries
to trace dependencies on a source file named the same as a target, which
makes no sense.  Furthermore, in code of the form

 add_executable(foo foo.c)
 add_custom_command(OUTPUT "${somewhere}/foo" ... DEPENDS foo)

the "vsProjectFile" value "foo" matches source "${somewhere}/foo.rule"
generated to hold the custom command and causes the command to be added
to the "foo" target incorrectly.

Simply drop the incorrect source file trace and supporting logic.

Stephen Kelly a6286e92c9 Fix the evaluation of per-config COMPILE_DEFINITIONS (#14037)
The API for retrieving per-config COMPILE_DEFINITIONS has long
existed because of the COMPILE_DEFINITIONS_<CONFIG> style
properties. Ensure that the provided configuration being generated
is also used to evaluate the generator expressions
in cmTarget::GetCompileDefinitions.

Both the generic COMPILE_DEFINITIONS and the config-specific
variant need to be evaluated with the requested configuration. This
has the side-effect that the COMPILE_DEFINITIONS does not need to
be additionally evaluated with no configuration, so the callers can
be cleaned up a bit too.
2013-03-25 10:49:22 -04:00
Stephen Kelly 3a298c0bf4 Fix generation of COMPILE_DEFINITIONS in DependInfo.cmake.
As INTERFACE_COMPILE_DEFINITIONS are now possible, we can have
situations like this:

 add_library(foo ...)
 add_library(bar ...)
 target_link_libraries(foo bar)

 target_compile_definitions(bar INTERFACE SOME_DEF)

The INTERFACE_COMPILE_DEFINITIONS of bar determine how foo should be
compiled, and if they change, foo should be rebuilt.

Additionally, as of commit d1446ca7 (Append the COMPILE_DEFINITIONS
from the Makefile to all targets., 2012-09-17), we don't need to
read definitions from the makefile if we read them from the target,
so also de-duplicate the cached info.

The DependInfo for INTERFACE_INCLUDE_DIRECTORIES is already handled
correctly.

Alex Neundorf 05f162ce95 AddCustomCommand: Handle multiple IMPLICIT_DEPENDS files (#10048)
The code handling IMPLICIT_DEPENDS was only able to track a single file,
the latest file replaced earlier files in the list.

The documentation now mentions that the language has to be prefixed to
every file and the test now uses two implicit dependencies, where only
the second is modified to trigger re-running of the custom command.

Brad King ee6c1b8aca Makefile: Support directory names containing '=' (#12934)
Since commit c8ef6430 (Allow directory names containing '=' and warn if
necessary, 2012-02-06) we allow directories with '=' instead of
rejecting them as was previously done since commit 8704525f (Reject
directory names containing '=', 2011-01-14).  However, we did not warn
in all cases that '=' may cause failure, such as when it appears on the
right-hand side of a dependency line.

Both commits above were made assuming that '=' cannot be escaped in Make
syntax, but it can be achieved with a variable:

  EQUALS = =
  left$(EQUALS)side : right$(EQUALS)side

Use this approach to escape '=' in dependency lines, thus supporting
the character in paths.

All our tests now pass when CMake is built in source and build trees
both containing '=', except for the "OutOfSource" test.  It fails in
its coverage of the obscure "OutOfBinary" test case where part of the
build tree is located outside the main build tree of the test.  The
reason is that CMake must invoke a command like

  $(MAKE) -f /path/with=sign/build.make /path/with=sign/somefile

but the make tool interprets the last argument as a variable assignment.
This is an acceptable limitation, since the case is so obscure, in
exchange for supporting '=' cleanly otherwise.

Brad King c8ef6430e0 Allow directory names containing '=' and warn if necessary (#12934)
The approach taken by commit 8704525f (Reject directory names containing
'=', 2011-01-14) was perhaps too heavy-handed for avoiding the obscure
cases when '=' in the path fails due to limitations of Make syntax.
Only two CMake tests:

  LinkDirectory
  OutOfSource

fail when the path contains '=' and they cover obscure cases.  Instead
of rejecting such paths outright just warn when the problem may occur.

The Watcom WMake tool has trouble running commands in paths that have
parentheses.  We already convert most commands to a shortpath for Watcom
if the path contains a space, but the use of $(CMAKE_COMMAND) hides the

that contain parentheses as well as spaces.  Use the new method to
convert the value of $(CMAKE_COMMAND) and other helper variables.

While all modern versions of windows have shells that support it, the

David Cole 269a4b876a Enable calling commands with : in argv[1] (#9963)
The solution seems hackish, but it works: for
NMake only, prepend a no-op command before each
real command that begins with ".

This is really a work-around for an NMake problem.
When a command begins with ", nmake truncates the
first argument to the command after the first :
in that arg. It has a parsing problem.

Workaround..., hackish..., but it should solve
the issue for #9963 and its related friends.

Also, modify the CustomCommand test to replicate

Alexander Neundorf 39383ef8cb Major optimization of C/C++ dependency scanning.
Now only the dependencies for the file where the dependencies actually may
have changed are rescanned, before that this was done for all source files
even if only one source file had changed.
This reduces e.g. on my machine the time for scanning the dependencies
of kdelibs/khtml/ when only one file (khtml_global.cpp) has changed from
around 7.5 seconds to 1.2 seconds.

The tests succeed, it does what I expected it to do on kdelibs, and Brad

Alexander Neundorf 298de4374b Major improvement of the generated targets in Eclipse.
Before this change all targets were displayed in the top level directory of
the project. Now the targets are displayed in the correct directory.
The targets "clean" and "all" are now created in every subdirectory.
Also now the targets for just compiling one file, preprocessing one file,
assembling one file are are created for Eclipse.
Additionally all targets get a prefix now in eclipse, so that they are
sorted in a way which makes sense (global targets first, then executable and
libraries, then object files, then preprocessed, then assembly). Also
this prefix gives the user a hint what the target is, i.e. whether it's a
library or an executable or something else.
