The proposed patch for the issue could not be applied as is
because the SOURCE_DIR always exists for an ExternalProject_Add
call by the time we get to the place to emit the potential error.
The fix is to emit the error only if the source dir is empty.
By which, I mean devoid of files and subdirectories. If
SOURCE_DIR is used by itself, without any DOWNLOAD_COMMAND
or repository info, then it implies that the SOURCE_DIR is ready
to build as-is without need for a download step. Clearly, if it
is empty, then it is not ready to build as is. So complain if
the SOURCE_DIR is empty.
Override CMAKE_DOC_DIR and CMAKE_DATA_DIR cache entries on Cygwin early
enough so the new values are used everywhere. Previously only some of
the uses were overridden. Also set CPACK_PACKAGE_VERSION to the whole
CMake_VERSION so that the Cygwin MANIFEST file goes in the proper path.
The warning appears everywhere we use static_cast to explicitly truncate
an integer width. It appears in the form
cc-3968 CC: WARNING File = ..., Line = ...
implicit conversion of a 64-bit integral type to a smaller
integral type (potential portability problem)
static_cast<...>(...);
^
which is strange because a "static_cast" is not implicit. It also
appears in system library code.
Use 'git fetch' followed by 'git reset' to update the source tree. This
is better than 'git pull' because it can handle a rewritten upstream
branch and does not leave local modifications. After fetch, parse
FETCH_HEAD to find the merge head that 'git pull' would choose to track
the upstream branch. Then reset to the selected head.
In the normal fast-forward case the behavior remains unchanged.
However, now local modifications and commits will be erased, and
upstream rewrites are handled smoothly. This ensures that the upstream
branch is tested as expected.
Teach (create|run)_dashboard_script macros to treat the argument as the
name of a build tree. Append '.cmake' to generate the dashboard script
name. This allows future re-use of the macros for multiple test
scripts.
Commit 82c081ba (Fix rpath-link flag for SunPro C++ on Linux,
2009-07-13) taught CMake to pass '-rpath-link' because SunPro C++ 5.9
does not support '-Wl,'. Now SunPro C++ 5.11 does not recognize the
option without using '-Wl,'. Detect whether to use '-Wl,' based on the
output of "sunCC -flags".
Commit 67277bac (Teach ctest_update about Git submodules, 2010-05-04)
accidentally logged "git submodule update" with the prefixes "pull-out"
and "pull-err". Fix it to use "submodule-out" and "submodule-err"
instead.
The CopyFileIfDifferent, CopyFileAlways, CopyAFile and CopyADirectory
methods should always copy permissions. The special cases in which a
caller would pass copyPermissions=false should be handled at the call
site. The parameter needlessly complicates the interface and semantics
of these methods.
Use it from ExternalProject and the ExternalProject test's
CMakeLists file rather than having duplicate find_program calls.
Add logic so that we do not try to use *.cmd variants of git
programs when using the MSYS Makefiles generator. Should fix
the last remaining dashboard issue with the new ExternalProject
git support additions.
Also, correct minor problem regarding placement of the local git
repo during test execution. On clean builds, it was being placed
incorrectly because of the ../.. relative reference. Use an absolute
path to place the local git repo in the proper directory, and only
use the relative reference when referring to it.
If there is a .bat or .cmd file used as a custom command
then the Borland Makefiles generator (specifically) requires
using the "call " syntax before the name of the .bat or .cmd
file. This fix applies to all Makefile based generators where
WindowsShell is true.
