Re: [CMake] ExternalProjects: How do ExternalProject_add and ExternalProject_Add_Step interact?
I tried just listing the single step, and for some reason (probably my
fault) it didn't work.
I did get this working, but I had to add two things to keep tcl and tk
from breaking fixup_bundle -- I had to make the Tcl/Tk SO libraries
writable, and I needed to delete tclsh and wish, because fixup_bundle
didn't like their link dependencies.
set(TCL_DEPEND tcl)
set(proj tcl)
ExternalProject_Add(${proj}
CVS_REPOSITORY ":pserver:anonymous:@tcl.cvs.sourceforge.net:/cvsroot/tcl"
CVS_TAG -r core-8-5-7
CVS_MODULE "tcl"
CONFIGURE_COMMAND
sh ${CONFIG_WRAPPER}
${BRAINSTracer_BINARY_DIR}/tcl-prefix/src/tcl/unix/configure
--prefix=${BRAINSTracer_BINARY_DIR}
INSTALL_DIR ${BRAINSTracer_BINARY_DIR}
UPDATE_COMMAND ""
)
if(APPLE)
set(SHARED_LIB_EXT .dylib)
else(APPLE)
set(SHARED_LIB_EXT .so)
endif(APPLE)
ExternalProject_Add_Step(${proj} after_install
COMMAND chmod u+w ${BRAINSTracer_BINARY_DIR}/lib/libtcl8.5${SHARED_LIB_EXT}
COMMAND cmake -E remove ${BRAINSTracer_BINARY_DIR}/bin/tclsh8.5

Re: [CMake] ExternalProjects: How do ExternalProject_add and ExternalProject_Add_Step interact?
There is some info at
http://www.kitware.com/products/archive/kitware_quarterly1009.pdf
based on that I thought it was enouth do depend upon just the install in
your case...
I am collecting external projects for several libs, It seem you are
building at least VTK and Tcl and Tk that I lack...
Do you mind sharing?
my stuff is (dis)organized as a series of packages and assemblies... far
for being cross platform and complete though
If you like, have a look at
http://3d.cineca.it/storage/bazaar_repo/CmakeDeps/lib/wt/
Thanks in advance

ExternalProject_Add creates a project, e.g.
ExternalProject_Add(tcl
CVS_REPOSITORY ":pserver:anonymous:@tcl.cvs.sourceforge.net:/cvsroot/tcl"
CVS_TAG -r core-8-5-7
CVS_MODULE "tcl"
CONFIGURE_COMMAND
${BRAINSTracer_BINARY_DIR}/tcl-prefix/src/tcl/unix/configure
--prefix=${CMAKE_BINARY_DIR}
INSTALL_DIR ${CMAKE_CURRENT_BINARY_DIR}
UPDATE_COMMAND ""

When the generated makefiles actually build the project, there's a
directory named
${CMAKE_CURRENT_BINARY_DIR}/tcl-prefix/src/tcl-stamp
In which a 0-length file is created after each step of the external
project build is successfully finished. These files (and THIS is what
was undocumented, that I had to determine by poking around in the
build directories) are named
${proj}-mkdir ${proj}-download ${proj}-update ${proj}-patch
${proj}-configure ${proj}-build ${proj}-install ${proj}-done
Where 'proj' is the name you've given the ExternalProject. So in
order to add a step you have to list the steps your new custom step
depends on, after the DEPENDEES keyword. For example:
if(APPLE)
set(SHARED_LIB_EXT .dylib)
else(APPLE)
set(SHARED_LIB_EXT .so)
endif(APPLE)
ExternalProject_Add_Step(${proj} after_install
COMMAND chmod u+w ${BRAINSTracer_BINARY_DIR}/lib/libtcl8.5${SHARED_LIB_EXT}
COMMENT "--
${BRAINSTracer_BINARY_DIR}/lib/libtcl8.5.so installed read-only!"
DEPENDEES mkdir update patch download configure build install
)
Now it appears that you have to list ALL the prerequisite steps, not
just the one after which your step should occur.

[CMake] ExternalProjects: How do ExternalProject_add and ExternalProject_Add_Step interact?
So... I have been working on my 'Holy Grail' CMakeLists.txt that builds all prerequisites to my application as ExternalProjects, and then builds my application (also as an External Project). In getting it to work on OS X and Linux I ran into an issue: If you build Tcl, and install it, it installs the shared libraries for Tcl read-only. So, if I try and use fixup_bundle (from BundleUtilities) to make a standalone build with all shared libraries it fails: -- 82/204: copying '/scratch/kent/newbuild/BT-build/lib/libtk8.5.so' CMake Error at /opt/cmake-2.9.20100421/share/cmake-2.9/Modules/BundleUtilities.cmake:431 (file): file RPATH_REMOVE could not remove RPATH from file: /scratch/kent/newbuild/BT-build/bin/libtk8.5.so Error opening file for update. Call Stack (most recent call first): /opt/cmake-2.9.20100421/share/cmake-2.9/Modules/BundleUtilities.cmake:531 (copy_resolved_item_into_bundle) cmake_install.cmake:54 (fixup_bundle) So my thought was 'brilliant! I'll add a step to the ExternalProject!' -- but it isn't clear to me if ExternalProject_Add_Step is actually set up to modify an External Project, or if you're supposed to use ExternalProject_Add_Step commands to swizzle up your own custom External Project. More specifically If I have ExternalProjectAdd(xyz ... ) ExternalProject_Add_Step(xyz fix_permissions ... ) I don't know what to put for DEPENDEES to get fix_permissions to run AFTER the install. Any ideas? ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
