I'll add for example when it is processing languages, CMakeCInformation.cmake (and the CXX version) which that script assumes that it will be managing not only the compiler, but linker and libarian Why this way? Because in this case, there is ZERO need to do all of the "./configure" type testing and determination because at the end of the day, CMake will not be executing the compiler period. The IDE will do all of that work. This type of change is non trivial, and I'm wondering if it is the right approach or not. -Duane. -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.

Hmm - Another approach is to use Python to create the IDE files
And from that python script generate CMakefiles for the unit test
situation.
Sort of backwards from where I am starting, but that said - my focus is
the Embedded side, not the host.
One thing that is never easy is a "split language" development
environment. ie: Some stuff is done in C (the generator) - and some
stuff is done in Script (ie: Cmake Language)
you don't have a debugger for Cmake, just print statements, and you are
always asking your self the question: "Should this step be in Language
A, or Language B"

but that uses/requires/assumes - Make files are used to run the build.
Having the IDE execute Make - while doable, is *NOT* desired.
>> Are you familiar with cmake cross-compiling support in CMake ?
yes, I'm currently building Cmake from source, and stepping through the
code experimenting and learning how Generators work.
For my generator I basically need to make a dummy (does nothing)
generator and let everything be done in the template
Often it seems to always comes back to the generator and what needs to
be done there. It is same problem I talked about earlier - some things
are in CmakeScript, Some are in C, and others will be in the template it
self, and where does feature(X) need to be in C, or in Cmake or in the
Template?

this exists basically.
The files cmake loads are named --.cmake.
In CMake there are e.g. Generic-SDCC-C.cmake.
This would be "BareMetal" using sdcc.
You can write your own files for your own platforms.
OS and other settings can be set up in your toolchain file.
Are you familiar with cmake cross-compiling support in CMake ?
If not, please get into this, it handles many of the issues you have.

Re: [cmake-developers] new generator question - xml file output for embedded IDE platforms.
>> configure_file is not the right command
Yea, it's the nearest existing item, and it only does the most
simplistic replacement that's why I use that as a basis for my example.
It is in effect, like the final last 'sed' step done by gnu
autoconfigure tools. Nothing more.
>> If an IDE is actually not supported by CMake a generator it will have to be
>> implemented for that in the source code of CMake.
yea, i'm trying to avoid that - but I can write that if required :-(
It's more then the IDE, it is also the CHIP effectively the SYSTEM
What I need is the variable data that Cmake has already and I need to be
able to tell CMake that it *cannot* run the compiler instead, all of the
information about the compiler will be provided via some Cmake script,
for example names like this, either on the command line or specified in
a Cmake file that holds alot of variables.
Cmake-Embedded-${CompilerName}.txt
Cmake-Embedded-${ChipName}.txt
Possibly:
Cmake-Embedded-${RtosName}.txt
or
Cmake-Embedded-BareMetal.txt
And packages (aka: Libraries) that you might want to use would never be
discovered and would instead be specified in some form, for example
Cmake-Embedded-Package-${PackageName}.txt
An Embedded Package (aka: A static library) provided it does not require
a specific hardware access should EASILY be re-usable in a host
environment.
Thus, a package could provide for example
Cmake-Embedded-Package-HostLib-${PackageName}
And several unit test type applications like this.
Cmake-Embedded-Package-HostTest-${PackageName}
Key thing to remember, i'm approaching this from the *embedded*side*
where most - if not all of the flexibility found on a HOST simply does
not exist, thus moving an embedded package to host is easy because the
host side is far more flexibility then the embedded.
the WIN I am looking for is the "HostLib" and "HostTest" Cmake already
provides this, why re-invent the wheel.
Other alternatives is autoconfig - which - is very Windows Unfriendly,
lots and lots of embedded types use Windows - in some cases the IDE is
only available on windows.
Bottom line:
Given the information in the Cmake-Embedded-*.txt files there is enough
information to create the embedded IDE project files which are generally
simple XML files
And that's the idea ...
Thanks for your help & comments.
-Duane.

Re: [cmake-developers] new generator question - xml file output for embedded IDE platforms.
Hi Duane, As far as i understand from your mail you want to generate project files from CMake. Although I would appreciate a more powerful configure_file command (e.g. a built in generator like the mustache generator (https://mustache.github.io/) or something like that) i must confess that configure_file is not the right command for the feature you want. It is used to generate some files from templates (e.g. Header Files), actually in a simple form of exchanging placeholders with contents of a CMake Variables. It works like that: The feature which you want is done by the CMake Generators, which you can specify by the command line option -G (or you can select it with the cmake-gui). If an IDE is actually not supported by CMake a generator it will have to be implemented for that in the source code of CMake. There are generators which generate IDE projects, where you can build it with the IDE itselt (e.g. Visual Studio) and there are so called "Extra generators" which generate Ninja/Makefiles and additional project files for the IDE. The build can be done by the IDE, but it will run the Ninja/Makefiles (e.g. Eclipse CDT generator). https://cmake.org/cmake/help/v3.11/manual/cmake-generators.7.html The Toolchain and the Processor (Chip) may be specified by Toolchain Files, which can also be chosen by the cmake-gui or on the command line with the option -T . You may have several toolchain files for different toolchains (e.g. one for embedded and one for PC) Some information regarding that can be found here: https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/CrossCompiling https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html When CMake is run it checks for a working compiler. To check that CMake tries to compile a simple program. For embedded compilers it is not always possible without some special files (e.g. linker files), so CMake also provides a special mode for that where only a library is created instead of an executable. (See Variable CMAKE_TRY_COMPILE_TARGET_TYPE, https://cmake.org/cmake/help/v3.11/variable/CMAKE_TRY_COMPILE_TARGET_TYPE.html) Best regards, Matthias. -- matthias.goessw...@eeas.at /mail www.eeas.at /web +43 660 1280 131 /phone -- eeas gmbh Technologiepark 17 4320 Perg Austria -- ATU67456549 /uid FN385458a /firmenbuchnummer landesgericht linz /firmenbuch Am 01.05.2018 um 22:50 schrieb du...@duaneellis.com: > Hi - > > I'm looking into adding a new "generator" type, that is basically a > fancy form of "configure_file()" > > At this point, I've been stepping through Cmake code trying to > understand the general flow > and want to ask the question: Is this insane or stupid?
