This teaches the undocumented file(INSTALL) command to deal with
relative paths. Relative input file paths are evaluated with respect to
the current source directory. Relative output file paths are evaluated
with respect to the current binary directory.
While this command is currently used only in cmake_install.cmake scripts
(in -P script mode), this cleans up its interface in preparation for a
documented signature.
The undocumented file(INSTALL) is implemented by a cmFileInstaller class
inside cmFileCommand. This refactors the class to split out code not
specific to installation into a cmFileCopier base class.
This creates a single cmFileInstaller method to dispatch installation of
symlinks, directories, and files. The change removes duplicate tests of
input file type and makes the decision more consistent.
While copying a directory the destination must have owner rwx
permissions. This corrects our check, this time with correct operator
precedence using parenthesis.
This teaches the command to interpret relative paths with respect to the
location of the invoking CMakeLists.txt file. The convention is already
used by most commands and won't change the behavior in script mode.
When CMake 2.4 generates the build tree for CMake itself it asks the
built CMake to install itself using the rules that 2.4 generated. Since
the install rules use undocumented commands that are not compatible from
2.4 to 2.6 we need a special case to avoid failure. This sets a special
indicator variable in the install rules that enables a compatibility
hack to support the old install rule format.
The internal file(INSTALL) command argument parsing used several
booleans with at most one set to true at a time to track argument
parsing state. This refactors it to use one enumeration.
- CMake 1.8 and below did not do the check but could get in
infinite loops due to the local generate step.
- CMake 2.0 added the check but failed to perform it in directories
with no targets (see bug #678).
- CMake 2.2 removed the local generate which fixed the problem but
did not remove the check.
- Between CMake 2.4 and 2.6.0rc6 the check was fixed to work even
when no targets appear in a directory (see bug #6923).
- Bottom line: the check is no longer needed.
- If new RPATH is empty then remove the entry completely
- Preserve file modification time so installation is not repeated
- If installed file already exists remove it if its RPATH
does not match that expected
- Move computation of extended build-tree rpath
to cmComputeLinkInformation
- Only enable the extended build-tree rpath if
the target will be installed
- Generalize the interface of file(CHRPATH)
- When changing the rpath on installation only
replace the part generated by CMake because
the native tools (ex SunCC on Linux) might have
added their own part to the rpath
- Add cmSystemTools::ChangeRPath method
- Add undocumented file(CHRPATH) command
- When installing use file(CHRPATH) to change the rpath
instead of relinking
- Remove CMAKE_CHRPATH lookup from CMakeFindBinUtils
- Remove CMAKE_USE_CHRPATH option since this should
always work
with cmake cvs without this patch an invalid cmake_install.cmake script was
generated in this case, it failed with an error if no files were given. So
just do nothing if no files are listed to make it compatible.

offset can be specified where the reading starts, and using HEX the data can
be converted into a hex string, so binary data can be compared with text
functions
-add docs for LIMIT, OFFSET and HEX
Alex
conversion of hex and srec files to binary.
Without this automatic conversion, everywhere where a compiled file is parsed for strings the
a file(HEX2BIN somefile binfile) command has to be added otherwise it will
not work for these compilers. I tried this with DetermineCompiler and
CheckTypeSize and nobody will do this except the users who work with such
compilers. For them it will break if they don't add this conversion command
in all these places.
If FILE(STRINGS) is used with a text file, it
will in most cases still work as expected, since it will only convert hex
and srec files. If a user actually wants to get text out of hex files, he
knows what he's doing and will see the hint in the documentation.
Anyway, it should work without having to create a temporary file, will work
on this later.
Alex
-add a RESULT_VARIABLE to INCLUDE()
-add CMAKE_TOOLCHAIN_FILE for specifiying your (potentially crosscompiling) toolchain
-have TRY_RUN() complain if you try to use it in crosscompiling mode (which were compiled but cannot run on this system)
-use CMAKE_EXECUTABLE_SUFFIX in TRY_RUN(), probably TRY_RUN won't be able to
run the executables if they have a different suffix because they are
probably crosscompiled, but nevertheless it should be able to find them
-make several cmake variables presettable by the user: CMAKE_C/CXX_COMPILER, CMAKE_C/CXX_OUTPUT_EXTENSION, CMAKE_SYSTEM_NAME, CMAKE_SYSTEM_INFO_FILE
-support prefix for GNU toolchains (arm-elf-gcc, arm-elf-ar, arm-elf-strip etc.)
-move ranlib on OSX from the file command to a command in executed in cmake_install.cmake
-add support for stripping during install in cmake_install.cmake
-split out cl.cmake from Windows-cl.cmake, first (very incomplete) step to support MS crosscompiling tools
-remove stdio.h from the simple C program which checks if the compiler works, since this may not exist for some embedded platforms
-create a new CMakeFindBinUtils.cmake which collects the search fro ar, ranlib, strip, ld, link, install_name_tool and other tools like these
-add support for CMAKE_FIND_ROOT_PATH for all FIND_XXX commands, which is a
list of directories which will be prepended to all search directories, right
now as a cmake variable, turning it into a global cmake property may need
some more work
-remove cmTestTestHandler::TryExecutable(), it's unused
-split cmFileCommand::HandleInstall() into slightly smaller functions
Alex
fix many bugs related to target names being computed inconsistently.
- Centralized computation of a target's file name to a method in
cmTarget. Now that global knowledge is always available the
*_CMAKE_PATH cache variables are no longer needed.
- Centralized computation of link library command lines and link
directory search order.
- Moved computation of link directories needed to link CMake targets
to be after evaluation of linking dependencies.
This also removed alot of duplicate code in which each version had its
own bugs.
This commit is surrounded by the tags
CMake-TargetNameCentralization1-pre
and
CMake-TargetNameCentralization1-post
so make the large set of changes easy to identify.
