Hello cmake users
I want to put the current subversion revision into a script every time I run "make
install".
Currently, I use configure_file() to replace a variable in the script, but this only
updates the script when either the script or something in CMakeLists.txt changes. Is
there a way to update the script every time I run "make install"?
Did you try with
install([[SCRIPT <file>] [CODE <code>]] [...])
using this you may execute a CMake script at install time.
Good idea. This may lead to what I'm looking for. My svn_revision.cmake
script now looks like this:
find_package(Subversion)
if(Subversion_FOUND)
Subversion_WC_INFO(${ER_SOURCE_DIR} ER)
set(REVISION ${ER_WC_REVISION})
configure_file(${ER_SOURCE_DIR}/scripts/version.sh.in
${ER_SOURCE_DIR}/scripts/version.sh @ONLY)
endif(Subversion_FOUND)
It is invoked in CMakeLists.txt with "install(SCRIPT svn_revision.cmake)".
The only problem I have now is that ${ER_SOURCE_DIR} is not defined in the
external script. Is there a way to pass arguments to this svn_revision.cmake
script?
I don't know if you can pass arguments. But I personnally do it in another way
using configure_file + install(script like this:
CONFIGURE_FILE(svn_revision.cmake.in svn_revision.cmake @ONLY)
INSTALL(SCRIPT ${CMAKE_BINARY_DIR}/svn_revision.cmake)
Now the content of "svn_revision.cmake.in" should be something like:
find_package(Subversion)
if(Subversion_FOUND)
Subversion_WC_INFO(@ER_SOURCE_DIR@ ER)
set(REVISION @ER_WC_REVISION@)
configure_file(@ER_SOURCE_DIR@/scripts/version.sh.in
@ER_SOURCE_DIR@/scripts/version.sh @ONLY)
endif(Subversion_FOUND)
Ah great! I didn't think of the possibility to let cmake change a cmake
skript on the fly. It works perfectly.
Thank you very much for your help
James
