Vlad,


I have to come back to some Windows-specific issues:

See below - it seems this doesn't work in cmake 2.6.4.

Ok, I did this by calling "cmake -N -L".


This is the start of a current "INFO_BIN" file, identical for 32 and 64
bit except for the directory names in the "Source - Binaries ..." line
(yes, same host):

| =3D=3D=3D=3D=3D Information about the build process: =3D=3D=3D=3D=3D

| ...

Note this is cmake 2.6.4 which should be current (in the 2.6 line).

I don't have any issues with those specific "*.exe" file names written,
but I do miss the timestamp and the "generator" output.
Also, I'm a bit disappointed that neither on Windows nor on Linux I get
informed whether this was a 32 or 64 bit build, but so be it.

This is the code I used (with remarks inserted):

| MACRO(CREATE_INFO_BIN)
|   SET(INFO_BIN "Docs/INFO_BIN")
|
|   FILE(WRITE ${INFO_BIN} "=3D=3D=3D=3D=3D Information about the build p=
rocess:
=3D=3D=3D=3D=3D\n")
|   IF (WIN32)
|     EXECUTE_PROCESS(COMMAND date /c /T OUTPUT_VARIABLE TMP_DATE)
=46rom the result, "TMP_DATE" must be empty.

|   ELSEIF(UNIX)
|     ...
|   ENDIF()
|   SITE_NAME(HOSTNAME)
|   FILE(APPEND ${INFO_BIN} "Build was run at: ${TMP_DATE} on host
'${HOSTNAME}'\n\n")
|   FILE(APPEND ${INFO_BIN} "\nSource ${CMAKE_SOURCE_DIR} - Binaries
${CMAKE_BINARY_DIR}\n")
That line is for debugging only, will be removed.

|
|   # According to the cmake docs, this variable should always be set.
|   # However, it is empty in my tests, both cmake 2.6.0 and 2.6.4 on Lin=
ux.
|   # Include this code, so we will profit if a build environment does
provide that info.
|   IF(${CMAKE_HOST_SYSTEM})
|     IF(${CMAKE_CROSSCOMPILING})
|       FILE(APPEND ${INFO_BIN} "Build was done for ${CMAKE_SYSTEM}
using ${CMAKE_SYSTEM_PROCESSOR}\n")
|     ENDIF()
|     FILE(APPEND ${INFO_BIN} "Build was done on  ${CMAKE_HOST_SYSTEM}
using ${CMAKE_HOST_SYSTEM_PROCESSOR}\n\n")
|   ENDIF()
I may replace the above code by two separate "if", for "cmake_system"
and "cmake_host_system", but according to the docs I should get output
(no crosscompiling, so the values are identical, and only the second
line should appear).

|
|   # ${CMAKE_VERSION} doesn't work in 2.6.0, use the separate components=
=2E
|   FILE(APPEND ${INFO_BIN} "Build was done using cmake
${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}.${CMAKE_PATCH_VERSION} \n\n=
")
|
|   IF (WIN32)
|     FILE(APPEND ${INFO_BIN} "=3D=3D=3D=3D=3D Compiler / generator used:=
 =3D=3D=3D=3D=3D\n")
|     FILE(APPEND ${INFO_BIN} ${CMAKE_GENERATOR} "\n\n")
Also empty in the generated file.

|   ELSEIF(UNIX)
|     ...
|   ENDIF()
|
|   FILE(APPEND ${INFO_BIN} "=3D=3D=3D=3D=3D Feature flags used: =3D=3D=3D=
=3D=3D\n")
|   IF(EXISTS ${CMAKE_BINARY_DIR}/CMakeCache.txt)
|     # Attention: "-N" prevents cmake from entering a recursion, and it
must be a separate flag from "-L".
|     EXECUTE_PROCESS(COMMAND ${CMAKE_COMMAND} -N -L ${CMAKE_BINARY_DIR}
OUTPUT_VARIABLE FEATURE_FLAGS)
|     FILE(APPEND ${INFO_BIN} ${FEATURE_FLAGS} "\n\n")
|   ELSE()
|     FILE(APPEND ${INFO_BIN} "File 'CMakeCache.txt' is not yet found.\n\=
n")
|   ENDIF()
|
|   FILE(APPEND ${INFO_BIN} "=3D=3D=3D=3D=3D EOF =3D=3D=3D=3D=3D\n")
|
| ENDMACRO(CREATE_INFO_BIN)
