[CMake] Add suppport for new IDE

[forumer]

Hi,

I would like to add some support for generating makefiles/IDE solutions 
for the D language (http://dlang.org).
Especially I would like to be able to generate VisualD and monoD 
projects.
The language is hold inside files with a .d extension and that can be 
compiled by 3 differents compilers:


1)dmd: the official compiler
2)gdc: compiler based on gcc
3)ldc: compiler based on llvm


There is already a kind of makefile system called dub that build 
libraries/application but it cannot generate ide projects.
So in a perfect world it would be cool to add support for dub makefile, 
VisualD and MonoD.


Is there any example about how to do that ?
Do you support other languages except C/C++ ?



Thanks

[CMake] add_custom_command not triggered

[Nico Schlömer]

After downloading a file with ExternalData_Expand_Arguments [1], I would
like to execute a command on the data to produce another file. So far, I
have
```
ExternalData_Expand_Arguments(
  noshTestFetchData
  OUT_DATA DATA{${CMAKE_SOURCE_DIR}/test/data/${file}}
)
ExternalData_Add_Target(noshTestFetchData)

add_custom_command(
  OUTPUT ${CMAKE_BINARY_DIR}/test/data/pacman.e.2.0
  COMMAND decomp -p 2 ${CMAKE_BINARY_DIR}/test/data/pacman.e
  DEPENDS noshTestFetchData
)
```
The file is downloaded alright, but the `add_custom_command` is never
triggered. Why not?

This is with CMake 3.2.2.

Cheers,
Nico

I don't know anything about the ExternalData module but assuming this is 
unrelated ...


do you have a target that depends on the new output?
Without one the custom command does not get emitted.

E.g. add_custom_target(foobar ALL DEPENDS 
${CMAKE_BINARY_DIR}/test/data/pacman.e.2.0)
or list it in the sources of an existing add_executable() or 
add_library() target.

Oh wait, I read it wrong...

Try ${} to get the value of the variable. (It contains a file name, right?)

Re: [CMake] [Plplot-devel] [ANNOUNCE] CMake 3.4.0-rc1 is now ready!

Ah, thank you very much.  The attached patch fixes this.


Hi Orion:

Thanks for implementing Brad's suggestion to fix the PLplot Ada
language support issue for CMake-3.4.  To help give you PLplot git
credit for your work, would you please put the patch in "git
format-patch" form?

I also notice substantial use of  in the PLplot D language
support case. I assume your tests did not reveal any issues for D
because you were not trying any D compiler flags, but I predict if you
do that, you will encounter the same problem.  For example, if you try

export DFLAGS=-Iwhatever

I assume that (harmless) compile flag will correctly propagate to the D compile 
step (as seen
by the VERBOSE=1 option for make) for older versions of CMake but will
not propagate correctly for CMake-3.4.

Anyhow, I am virtually positive there is also a PLplot  D
language support issue for CMake-3.4 so if you don't beat me to it, I
plan (likely late next week because I am currently tied up with
something else) to expose that issue with a test like the one I
suggested above and also plan to fix the issue following Brad's
suggestion.

Re: [CMake] add_custom_command not triggered

[David Cole via CMake]

Because you're giving DEPENDS as a target name, this is only an ordering
dependency, stating that the command should run after the target is built.
But not necessarily re-build whenever the target is re-built...

If you want to re-run the command based on a file changing instead, then
use the full path to a file name as your DEPENDS argument. The downloaded
file itself, or the extracted data file the command uses would probably be
reasonable choices.

Read the DEPENDS section of
https://cmake.org/cmake/help/v3.3/command/add_custom_command.html carefully.


HTH,
David C.

Re: [CMake] add_dependencies being ignored for add_custom_command?

[Iosif Neitzke]

Yes, Header.hpp will be generated before the target is built.  I do
not believe the order of files listed in add_library() matters at all.

[cmake-developers] [CMake 0015823]: FIND_LIBRARY & TARGET_LINK_LIBRARIES

[Mantis Bug Tracker]

The following issue has been SUBMITTED. 
== 
https://public.kitware.com/Bug/view.php?id=15823 
== 
Reported By:Anthony Ette
Assigned To:
== 
Project:CMake
Issue ID:   15823
Category:   CMake
Reproducibility:always
Severity:   major
Priority:   normal
Status: new
== 
Date Submitted: 2015-10-31 14:46 EDT

== 
Summary:FIND_LIBRARY & TARGET_LINK_LIBRARIES
Description: 
On version 3.3.20150618.
I am not understanding the behavior of these two commands or am getting
inconsistent results.  Sometimes when the results of a found static library from
FIND_LIBRARY are passed to TARGET_LINK_LIBRARIES, it generates "/path/to/lib"
linker syntax BUT other times it produces a "-Wl,-Bstatic -llib -Wl,-Bdynamic"
syntax.  I've confirmed that both lib vars as returned from FIND_LIBRARY are
full paths to .a static archive files so how can the different handling at the
linker CLI be explained?

Steps to Reproduce: 
Unknown.  Some libs are handled one way and others are handled another.  The
only potential lead may be that they come from different paths on the file
system (say one from /usr/lib and another from /sim/lib/v67/ihawk).

Additional Information: 
None
