Perfect, thx (just fixed up the double-quote escaping a bit and things worked
fine).

Hmmm, OK, I'll look into reviewing this to see how things differ.

Re: [CMake] INSTALL CODE Error Results and Termination
Hi,
You also need to add the "if" statement into the "CODE" parameter, for
example something like this ...
install(CODE "If (NOT \${_res} EQUAL "0")
message( FATAL_ERROR \"out: \${_out}, err: \${_err}, res: \${_res}\")
endif()
")
To keep things simpler, you could also look at "INSTALL(SCRIPT ...)" it
would allow you to avoid escaping. You would just need to configure the
script using "configure_file".

One last item here: I'm now able to see the resulting variable values in the
message command output, but I'd now like to enclose this in an 'if' command.
Something like:
install(CODE "execute_process (
COMMAND ${CMAKE_COMMAND} -E echo \"Hello\"
OUTPUT_VARIABLE _out
ERROR_VARIABLE _err
RESULT_VARIABLE _res
)"
)
If (NOT \${_res} EQUAL "0") # escaping here has not effect one way or the
other...
install(CODE "message( FATAL_ERROR \"out: \${_out}, err: \${_err}, res:
\${_res}\")")
endif ()
However, the resulting cmake_install.cmake has the following (meaning the fatal
error message will always be executed regardless of the value of '_res"):
IF(NOT CMAKE_INSTALL_COMPONENT OR "${CMAKE_INSTALL_COMPONENT}" STREQUAL
"Unspecified")
MESSAGE( FATAL_ERROR "out: ${_out}, err: ${_err}, res: ${_res}...")
ENDIF(NOT CMAKE_INSTALL_COMPONENT OR "${CMAKE_INSTALL_COMPONENT}" STREQUAL
"Unspecified")
Is there a way to do this?

Aha! This was probably obvious to you and Kornel, but it "escaped" me ;).
Brilliant, this is working fine now.

Re: [CMake] INSTALL CODE Error Results and Termination
Hi David,
You need to escape the "$" sign otherwise the "_err", "_out" and "_res"
variables are resolved to an empty string.
Here is an example of what you could do:
-8<---8<--
cmake_minimum_required(VERSION 2.8.9)
install(CODE "execute_process (
COMMAND ${CMAKE_COMMAND} -E echo \"Hello\"
OUTPUT_VARIABLE _out
ERROR_VARIABLE _err
RESULT_VARIABLE _res
)"
)
install(CODE "message( STATUS \"out: \${_out}, err: \${_err}, res:
\${_res}...\")")

Yes, I see this. I also assumed that the ERROR_VARIABLE would be returning
non-zero text as well in this case. I will change to using RESULT_VARIABLE,
but, in both cases, it seems that I'm referencing the variable incorrectly
(either syntactically or in the incorrect context) since this/these is/are
always .

Ideally, I want to be able to test for the result of this variable (either
ERROR_VARIABLE or RESULT_VARIABLE) after the execute_process command completes
(during 'make install') to determine its result and to terminate (with error
message) when the command fails.

Well, this just has the following:
IF(NOT CMAKE_INSTALL_COMPONENT OR "${CMAKE_INSTALL_COMPONENT}" STREQUAL
"Unspecified")
EXECUTE_PROCESS (
COMMAND ant ...
WORKING_DIRECTORY /home/david/src/java
#OUTPUT_VARIABLE _out
ERROR_VARIABLE _err
#RESULT_VARIABLE _res
)
MESSAGE( FATAL_ERROR "err: ")
ENDIF(NOT CMAKE_INSTALL_COMPONENT OR "${CMAKE_INSTALL_COMPONENT}" STREQUAL
"Unspecified")
IF(NOT CMAKE_INSTALL_COMPONENT OR "${CMAKE_INSTALL_COMPONENT}" STREQUAL
"Unspecified")
MESSAGE("out: , err: , res: ...")
ENDIF(NOT CMAKE_INSTALL_COMPONENT OR "${CMAKE_INSTALL_COMPONENT}" STREQUAL
"Unspecified")
So it looks like the variable(s) is(are) being expanded (in the first case)
prior to running the 'ant' command. Any ideas why this might be?
Thanks,
-David
PS: I'm surprised that this isn't something that many, many CMake authors
need/require (i.e., the ability to terminate or otherwise operate on the
results of an "install code..." sequence). Especially given the availability of
the error, output, and result variable arguments to the execute_process
command. What is the proper syntax/pattern for this?

If you run 'cmake --help-command execute_process', you see:
...
If RESULT_VARIABLE is given the variable will be set to contain the
result of running the processes. This will be an integer return code
from the last child or a string describing an error condition.
...
So, if this is not "0", then you have an error condition.

Never did this. When do you want to see the message?
As I understand your code, only in call of cmake, e.g. at configuration time.

Re: [CMake] INSTALL CODE Error Results and Termination
Hi David,
You could look at the generated file named "cmake_install.cmake" to have a
better idea of what could be wrong ...
As a side note, there is also an issue with command like
"install(CODE|SCRIPT ..." there are always executed first in a given
directory. See [1] (Note that I couldn't find a issue in the tracker
referencing that problem ... will create one if no body find it)

No, I really do mean ERROR_VARIABLE (unless, of course, this variable does not
include the non-zero exit status of the EXECUTE_PROCESS command?).
BTW, I'm still curious about the (dual 'code') construct generally.
Specifically, if I do the following I never see the fatal error message (so I'm
wondering if there's still something wrong regarding the scoping of the message
command)?
install (CODE "EXECUTE_PROCESS (
COMMAND ant ...
WORKING_DIRECTORY ${PROJECT_SOURCE_DIR}/java
ERROR_VARIABLE _err
)
MESSAGE( FATAL_ERROR \"err: ${_err}\")
BTW, the following doesn't work either (each of the variables is empty):
install (CODE "EXECUTE_PROCESS (
COMMAND ant ...
WORKING_DIRECTORY ${PROJECT_SOURCE_DIR}/java
OUTPUT_VARIABLE _out
ERROR_VARIABLE _err
RESULT_VARIABLE _res
)
Install (CODE "MESSAGE( STATUS \"out: ${_out}, err: ${_err}, res:
${_res}...\")")
