[CMake] Last minute build-date file.

The problems I can see are: 1 - It is not portable as it uses the OS date command. 2 - It is not portable as it calls gcc directly. 3 - It will not work with Debug or Release builds unless I set additional target LINK_FLAGS_type properties. 4 - I wish the creation of the link_date.cc file could be done inline of the add_custom_command instead of requiring a separate file. (I got into quoting hell.) 5 - Sneaking link_date.o onto the link line with the LINK_FLAGS property is kind of a hack. Suggestions please. Thanks in advance. Bill This is just OTTOMH, but could you have something like this: #include string const std::string link_date( __DATE__ ); const std::string link_time( __TIME__ ); in a separate blah.cc file? Then set the blah target to one of the PHONYs in the Makefile (those are the ones that always recompile regardless, right?), and make sure it's a requirement for every link.

Re: [CMake] How would I use parallel make on ExternalProjects?
There is one problem with that, which is what I'm trying to address: load balancing. If your project builds ITK, VTK, and sundry other prerequisite libraries, it will spawn 4 sequential builds. In practice this means everything except ITK (which we build with wrapping on) finishes, and then ITK chugs along doing its sequential build. If I do what I'm talking about, I'd sequentially conduct parallel builds of ITK VTK etc. In which case the big hairy libraries, like ITK with wrapping, get built in parallel. Have you considered distcc? It's essentially a compiler load balancer and fairly mature by now. I don't think it works on Windows though, so if you need that it might not be what you want. ___ 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
[CMake] Disallowing in-source builds
is there an easy way to clean out a source tree if an in-source build was accidentally kicked off? (short of dividing the files by their timestamp and removing the newer ones, etc..) My immediate thought was, does make clean not work for you? But I guess you're talking about CMake debris rather than make debris. Ideally, I?d like to prevent it before any cruft is written into the source tree. I suggest an alternative. I think I read about it on this list but I'm not sure. What I do is provide an empty cmake folder in my source tree root, and run all CMake commands in it. This ensures all the CMake cruft is contained in one in-source folder. (I guess you could modify this so it's out-source.) To re-run the rootwards-most CMakeLists.txt file: cd projectx/cmake cmake .. Then, to clear all CMake debris: rm -r projectx/cmake/* (insert usual disclaimer on rm usage) This doesn't prevent anything, but it does at least make it easy to build in-source without cluttering the source tree. Is there a good way to disallow in-source builds? Probably the best way is to circulate an email stating the lead developer has threatened to eat^H^H^H^H fire anyone who builds in-source. You could maybe do something with user permissions and build scripts. Make sure the build scripts only work in one place.

[CMake] CMake/MinGW/Windows XP 32-bit: command line arguments delimited by semicolon?

Why are the command line arguments separated by semicolons? It should be spaces. I've looked in the generated Makefile and CMakeCache.txt but I can't figure it out. This MinGW installation has been installed and working for a little while now, so I don't think it's a MinGW problem.

I assume Linux CMake will tolerate the double quotes, I'd hate to have more than one set of CMakeLists.txt files.

Seems one is an expanded version of the other. The value does seem to
be correct.
Could you explain me why the buildbot would have an invalid HOME
Heh. This takes some explaining. Here goes. HOME is actually defined
correctly in /etc/passwd as /var/lib/buildbot. (Why buildbot chose
*that* as opposed to /home/buildbot I don't know.)
The buildbot script is in two parts, buildmaster and buildslave. The
buildslave(s) run a series of build steps (darcs pull, make all,
etc) whenever they're told to. The buildmaster coordinates the actions
of the buildslaves and contains the build steps.
Let's assume the buildmaster is up and running already, and the
buildslave is already configured. Here's how I start the buildslave.
1. Log into the buildslave over SSH using my normal user account,
fatman. The SSH daemon is set for public-key authentication only, so
fatman is the only account I can use.
2. Switch to a bash shell controlled by my non-login-enabled account,
buildbot, using the command sudo -u buildbot bash. Note, HOME
still points to /home/fatman because sudo doesn't change user
context.
3. Start the buildslave. It detaches itself from the console.
4. Exit from the buildbot shell and log out, leaving the buildslave
running in daemon mode.
Now, note that the buildslave environment is running with user
buildbot, but has the HOME of user fatman. When the buildmaster
instructs it to start a build and it gets around to running CPackRPM,
it still has the wrong HOME.
If yes from which user to su from using which method (a,b,c,d,e)?
c) sudo
from your point of view should I see the problem or do you have some
other steps I miss ?
No, that is essentially what I do. You will see the problem.
error: failed to create directory %{_topdir}: /home/fatman/rpmbuild:
Permission denied
May be you can send me the whole rpmbuild.err and rpmbuild.out files?
The .out file is empty, and the .err file contains only that single
line.
build...@nikko:/var/lib/buildbot/Reu2/slave/bin/nikko/build/cmake$ cat
_CPack_Packages/Linux/RPM/rpmbuild.err
error: failed to create directory %{_topdir}: /home/fatman/rpmbuild:
Permission denied
build...@nikko:/var/lib/buildbot/Reu2/slave/bin/nikko/build/cmake$
My interpretation: rpmbuild is trying to make a temporary folder in
HOME and build the RPM package in it. HOME is wrong, so the permissions
for HOME are inappropriate, and we get permission denied. Does that
sound plausible?
Note the different user. This is why the HOME variable is wrong.
Why would it be wrong?
I believe you are correct about su, but I'm using sudo, which for
reasons I forget doesn't switch user context (in Ubuntu at least).
/var/lib/buildbot/Reu2/slave/bin/nikko/build/cmake/_CPack_Packages/Linux/RPM
is the previous directory belonging to user buildbot ?
User buildbot owns /var/lib/buildbot and all subdirectories and files.
By the way, I am also building a DEB and TGZ package. They both
complete successfully.
Yes but even if rpm building is enabled on Debian based host it's
possible that rpmbuild is not working as expected on such host.
Quite so. I meant that the aberrant behaviour seems to occur in the
part of the system governed by CPackRPM, rather than CMake, CPack,
CPackDEB or CPackTGZ (if those are the names).
By any chance do you have any other buildbot machine which would be
RPM based which exhibits the same trouble?
No. I do have a temporary buildslave, Vostro, running Ubuntu 32-bit.
The entire build succeeds and I get a pretty green column in my
buildmaster's waterfall webpage :D We don't see the same error because
I'm using my main user to start the buildslave. So

Re: [CMake] CMake/Buildbot xplat upload?
CMake is integrating well with Buildbot to make a sort of poor-man's build farm. The one thing I can't seem to work out is a crossplatform way to upload CPack-built packages (Windows and Linux) to a web server (Ubuntu). that's true you have file(DOWNLOAD ...) (which internally uses libcurl) so it should be fairly easy to add file(UPLOAD ...) but currently AFAIK this does not exists... may be worth a feature request. I'll do that. It would certainly save me some scripting headaches. The target web server supports SSH, SCP, DAV and possibly NFS. Any ideas? Or should I be asking Buildbot's mailing list? I don't know or use buildbot but it appears to be written in python so may I guess python may be required when using build bot. May be using some 100% python SSH lib (in order to be cross platform) like paramiko (http://www.lag.net/paramiko/) is doable in order to transfer your files using scp. You may call your python scp script from CMake using execute_process after a find_package(PythonInterp). Correct, Buildbot is a Python script. I only brought Buildbot up because (it seems to me) uploading is one of those edge use cases, where it could fall into the purview of either system, and I wasn't sure if this was more a Buildbot feature or not. (It's a barrel of fun getting Buildbot to run at all on a Windows machine, never mind as a service, and never mind as a Windows 7 service, but I did it anyway.

As a total non-expert I don't see how this will work because if build

CMAKE_CXX_FLAGS.

Could be. I too am a non-expert. CMake doesn't seem to output the

Can I make CMake more verbose? The IO log above contains the command
line executed by Buildbot (cd cmake make all cd ..).

[CMake] Error finding boost libraries
From: David Aldrich david.aldr...@eu.nec.com Subject: To: cmake@cmake.org cmake@cmake.org The following command is not working for me: find_package( Boost 1.40.0 COMPONENTS python REQUIRED ) I get error: CMake Error at CMakeLists.txt:36 (find_package): Could not find module FindBoostLibs.cmake or a configuration file for package BoostLibs. I am running CMake 2.8.2, which contains 'FindBoost.cmake' (NOT FindBoostLibs.cmake). Is this a known problem? I notice you specify Boost.Python. This is possibly a non-sequitur, but I've had problems with Boost.Python in the past, in particular when I tried to compose a pkg-config file (.pc) for it. The rest of Boost works just fine with pkg-config, as it turns out. It's just Boost.Python I had to give up on. IMO, the Boost.Python binary is inherently warped. ___ 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
Re: [CMake] CMAKE_CXX_FLAGS [was: Re: CMake Digest, Vol 77, Issue 104]
Could be. I too am a non-expert. CMake doesn't seem to output the command lines it executes, or if it does then Buildbot ignores it. This is the view from Buildbot's IO log: snip blah Can I make CMake more verbose? The IO log above contains the command line executed by Buildbot (cd cmake make all cd ..). You can run cmake and then: make VERBOSE=1 to see the flags. Thanks! I'll insert that into the builder configuration, sighup the buildmaster and force a build. Then we'll smell what CMake is cookin'. ___ 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
Re: [CMake] CMAKE_CXX_FLAGS
I'll insert that into the builder configuration, sighup the buildmaster and force a build. Or at least I will when the server lets me in. It's started doing this odd thing every day where it works until I try and SSH into it, then it goes offline for an hour and when it comes back I can SSH into it fine. Something else to fix. I hate computers. ___ 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
Re: [CMake] CMAKE_CXX_FLAGS
It let me in more quickly than usual today. Let's look at the IO log.
cd cmake make VERBOSE=1 all cd ..

secs)

I think I'll leave VERBOSE on, I like detailed logfiles.
Looks like you're right. This is my debug build, and I don't see any of
my flags in there (--pedantic, --std=c++0x, --gdwarf-2, etc).
I'll alter my CMakeLists.txt and see if your suggested edits make a
difference.
