Re: [cmake-developers] cmake server mode

2016-09-28 Thread Tobias Hunger

Hi Michele,

cmake -E server mode will always trigger something in cmake, so the
help will report that. I think it is nicer to report "Server mode
unavailable" when somebody attempts to run "cmake -E server" when that
is not available than to produce a "Unknown command".

To check whether or not server mode is available you can run "cmake -E
capabilities": That has a "serverMode" key with a boolean in its JSON
output. Easy to parse:-)

Gcc 4.8 should be new enough to enable it, there is only very light
C++11 usage, but I admit that I am not sure about MSVC2010.

Your build errors seem unrelated to server-mode.

Best Regards,
Tobias

[cmake-developers] cmake server mode

2016-09-28 Thread michele pagot

I'm interested in the cmake server mode. I've started from 
https://steveire.wordpress.com/2016/01/24/cmake-daemon-for-user-tools/ and then 
to  https://github.com/steveire/CMake.git and finally to the cmake official  
git master branch as it seems e

I rebuilt it from scratch on Windows trying both VS2010 and MinGW. With this 
second one, using gcc4.8. Everything seems fine as the build works as expected 
and

the inline help report server mode with both compilers.

the  new feature seems to be activated only if some special compiler capability 
are fulfilled. So I've changed compiler to gcc5.3 and now I'm even nor able to 
build due to errors like:

Re: [cmake-developers] Remove RPATH on install

That adds it in a way that hides its presence from CMake.  CMake has its
own way to specify RPATH entries in the build tree.  It will replace the
build-tree-only entries with install-tree-only entries (if any) during
installation.
I'm not aware of any better ways to apply global settings for all 
targets without modifying CMakeLists.txt



   Any entries it doesn't know about are assumed to be added
by the toolchain and are thus preserved.

I can't save them because it's full path hence will be not relocatable.



If one uses target_link_libraries to link each executable explicitly
to the shared library via absolute path to the library file then IIRC
CMake will put the RPATH in the build tree for that and remove it on
installation.

Yep, I know.




adding new one, like CMAKE_INSTALL_DELETE_RPATH?

We don't actually define any kind of first-class RPATH-update operation.
It is only an implementation detail that we edit the RPATH on installation.
In principle the design is that there is a build tree RPATH and an install
tree RPATH.  On non-ELF platforms we actually need to re-run the linker
to produce the install tree version.  Therefore CMAKE_INSTALL_DELETE_RPATH
would not fit within our model.

Ok


Instead one could add a BUILD_RPATH target property with CMAKE_BUILD_RPATH
variable that specifies additional entries to put in the build tree RPATH.
This would be the build-tree equivalent to the INSTALL_PATH target property.


Should work too. I will do the tests and send a patch.

[cmake-developers] Remove RPATH on install

2016-09-28 Thread Ruslan Baratov via cmake-developers


Hi,

I want to link the library to all executables in project so I'm adding 
` -Wl,-rpath,` to CMAKE_EXE_LINKER_FLAGS. That works 
fine however after install step this RPATH was not removed and full path 
to  remains as part of executable in LC_RPATH. As far as I 
understand there is no such variable for now in CMake that holds the 
list of RPATH directories that need to be removed on install step. If it 
is true what about adding new one, like CMAKE_INSTALL_DELETE_RPATH? Just 
for the record  is not a part of CMAKE_INSTALL_PREFIX or 
CMAKE_BINARY_DIR.

Please patch cmAuxSourceDirectoryCommand.cxx directly.  KWSys Directory
is a low-level API whose clients may not all need sorting.
