I have installed both the GNAT Programming Studio (GPS) and GtkAda. They both seem to work fine, but when I try to build the Simple Window project under New Project from Template, I get a bunch of errors saying "file gtk.ads not found." This seems to be a directory/dependency sort of problem - GPS doesn't know where to look for GtkAda. I'm running Windows 7, and have GPS installed at C:\GNAT\2011, and GtkAda installed at C:\GtkAda. I tried adding GtkAda to my PATH; at the moment my PATH user variable includes C:\GNAT\2011\bin, and my Path System variable includes C:\GtkAda\bin. Any advice on resolving this problem is greatly appreciated!
There are two things here.
First, "project" is key. Whenever you're building something that depends
on a library like GtkAda, it's much much easier if (a) you use GNAT
Project to manage it, and (b) you use the GPR(s) provided by the library
- always assuming it does, of course.
In the case of GtkAda, that means that your GPR needs to "with" GtkAda;
with "gtkada";
project Tinkering is
...
Second, gnatmake or gprbuild needs to be able to find gtkada.gpr.
The easiest way is to install GtkAda in such a way that gtkada.gpr is in
the default place that gnatmake/gprbuild expect to find GPR files. This
is $prefix/lib/gnat. GtkAda obeys this convention, so you could install
GtkAda under the same root as your compiler. I don't know why that's not recommended anyway.
If you don't want to do that, you can add the correct location to the
environment variable ADA_PROJECT_PATH, for example in your case set it
to C:\GtkAda\lib\gnat.
There is a lot of good stuff in the GtkAda README at libre.adacore.com, and in
the GtkAda User's Guide which I see from the README is also included with the
installed package at (in your case) C:\GtkAda\doc\GtkAda\gtkada_ug.

I'm writing my first KDE plasmoid using QML. The hello world example uses a metadata.desktop file, while this KDE Plasmoid tutorial talks about a metadata.json instead and says that the metadata.desktop is 'discouraged' now and a desktop file should be converted to json using desktoptojson.
However, when I browse the globally installed plasmoids under /usr/share/plasma/plasmoids/ they all have both the metadata.desktop and metadata.json.
First question: So, what is really recommended? Just the metadata.json? Or both?
And, I wasn't able to find the desktoptojson tool. I'm using Linux Mint and the ./kdesrc-build --initial-setup for debian based systems says that it's "This is woefully incomplete and not very useful" ... I read that "most users of this [i.e. desktoptojson] utility will use the CMake macro kservice_desktop_to_json as part of the process of building a plugin.". However, I haven't found the documentation yet how to use this.
Second question: In case one should maintain both files (for whatever reason), should I use desktoptojson to keep them in sync? And if yes, how?
Thanks!
First question: So, what is really recommended? Just the metadata.json? Or both?
In the current source code, most stock KDE applets such as the task manager use metadata.json's and have dropped the metadata.desktop's. It may be that the desktop files you have locally are left over from old versions, the new format was installed but the old one was never deleted.
Second question: In case one should maintain both files (for whatever reason), should I use desktoptojson to keep them in sync? And if yes, how?
The man page on Arch you linked to has all the information. The tool is part of the package kservice. Find the equivalent in the repository for your distribution. Then, to use it
as part of a CMake macro:
add_library(myplugin MODULE ${myplugin_SRCS})
kservice_desktop_to_json(myplugin myplugin.desktop)
directly on the command-line:
desktoptojson -i myplugin.desktop -o myplugin.json
I'm writing a custom check for installed libraries in autoconf:
AC_DEFUN([AC_GHC_PKG_CHECK],[
...
GHC_PKG_RESULT=$($PYTHON autotools/check-ghc-version-range ....)
...
])
where my Python script that actually performs the check resides in the autotools/ sub-directory of the project.
However, this is not portable, for example make dist-check fails because then autoconf tools are called from a different directory. How can I reference the absolute path to my Python script so that it gets called properly no matter what the current directory is?
ac_top_srcdir or ac_abs_top_srcdir should work in this case:
AC_DEFUN([AC_GHC_PKG_CHECK],[
...
GHC_PKG_RESULT=$($PYTHON $ac_top_srcdir/autotools/check-ghc-version-range ....)
...
])
EDIT: I don't think this approach will work -- it seems that $ac_top_srcdir aren't evaluated until later (AC_OUTPUT?).
What I think might work in this instance is to do something similar to what the runtime C tests do: blast a configuration test to a temporary file (conftest.py instead of conftest.c in this case) and run it. Unfortunately, there's (yet) no builtin macros or for automake/autoconf other tools that directly assist with this task.
Fortunately it seems that a clever person has written at least a couple different ways to do this. The first one is GNU pyconfigure which seems to have facilities for writing Python test code as I described above. The second one is more of an ad hoc macro collection that he used for his project.
You can use $srcdir.
It's not necessarily an absolute path, but it's a path that points from the top of the build tree to the top of the source tree.
I'm developer on a big system (>100 Projects in Solution, >100 000 LOC, > 10 Services, ...) and did the installation of this system in the past with wix and it worked fine. Now I need a way to patch (Minor Upgrade) parts of the system and run into several issues.
My Current Wix Setup is as following:
I have VS2010 and Wix3.6 Toolset and TFS2012 to Build the whole thing and get an installer
I'm using a Setup Library Project Type per Service
I'm using exactly one Setup Project to bundle things together and get one installer for the whole system.
It's not possible to change this setup.
The Setup Library Projects are set up as following:
I use the heat-directory msbuild task to generate the components and files and I'm using preprocessor variables to modify the file paths.
I need to modify the file paths because it must be possible to build an installer on the local developer system and to build the installer on the tfs build system which is different in folder structures.
The TFS uses always the same directory to compile subsequent versions of the software and moves the output after successful compilation to a unique folder structure.
Now I need a patch.
I created the Patch.wxs and called candle and light for it. I called torch to get the difference file. And finally want to create the patch with pyro.
Everything worked fine with a simple testproject, but on the big system
Pyro has the problem that it can't find the files to install.
Through my setup (see above), I must use preprocessor variables and have a full qualified path in my wix output (for example: C:\builds\myproduct\prodct.exe as file source). After moving the TFS output to another location this path is not valid anymore. I tried to use -bt and -bu switches for pyro, but this does only work for relative paths or for named bindpaths.
Now I wanted to change my wix project setup to use named bindpaths rather than preprocessor variables, but it seems that this is not possible.
heat can only use preprocessor variables or wixvariables but it seems not to be possible to use bindpath variables. heat provides a switch -wixvar which should create binder variables instead of preprocessor variables but I does exactly nothing.
Now I tried do use no wix and no preprocessor variables in heat and tell light per -bu -bt switches where to find the files. But if I do not set a preprocessor variable the resulting files look like Sources\product.exe. I can't get rid of this Sources. I know that I can transform all the xml with xslt and remove the Sources but thats a workaround which I would only implement if no other solution is possible. This would also mean that there is a problem in the wix toolchain.
It looks like pyro does only support bindpath variables and heat does only support preprocessor and wix variables. This seems to be really crazy, because how should they work together?
How can I create a patch if I use lit, light, candle, heat, torch and pyro and if the original build paths have changed (which is very common on a build system) and the file paths are created with heat and therefore be fixed or preprocessor or wix variables?
As you've found heat wasn't designed to be used in the patching scenario. It was only in recent versions of the WiX toolset that the generated GUIDs got to a point where there was even a chance that heat could successfully build output that would be patchable. Still need to do work there to make patching where heat is used work well.
Ultimately, I believe the answer is to simplify the "original source" problem. It is challenging to get all the bindpaths set up correctly and that makes patching, which is a hard problem, even harder. We've kicked around a few ideas but nothing has come together yet.
You could always use admin image based patching. It's slower but can be easier to get the "original source" and "target" laid out. That path does lose filtering though.
Basically, we need to do a bit more work in patching scenarios to make it much easier.
PS: "Source" in the path for a File/#Source attribute is an alias for the "default bindpath". You can use bindpaths there.
I'm writing a command-line utility in Go that (as part of its operation) needs to get a password from the user. There's a great gopass module for Unix that does this, and I know how to write one for the Windows console. The problem is that the Windows module obviously won't build on *nix, and the *nix version won't build on Windows. Since Go lacks any preprocessor support (as far as I can tell), I have absolutely no idea what the right way to approach this is. I know it's possible, since Go itself must do this for its own libraries, but the tooling I'm used to (conditional imports/preprocessors/etc.) seems to be missing.
Go has build constraints, which can either be specified as comments in a .go file, or as part of the file name.
One set of constraints is for target operating system, so you can have one file for Windows, one for e.g. Linux and implement the same function in two different ways in the two.
More information on build constraints are at http://golang.org/pkg/go/build/#hdr-Build_Constraints
Need To Set Version Information on the existing .dll
I need to add these to dll
1.File Version
2.Product Version
Tried this free version.
does not work
any Idea ?
There is a tool named verpatch that does exactly that.
After you download it you can run it from command line as below:
verpatch your.dll /pv "product.version" /va "file.version"
There are many other flags that can be used to add extra information.
Try:
verpatch /?
There is Resource Tuner Console from Heaventools Software.
Resource Tuner Console is a command-line tool that enables developers to automate editing of different resource types in large numbers of Windows 32- and 64-bit executable files.
See specifically the Changing Version Variables And Updating The Version Information page for greater details.
I've created a tool for this purpose because didn't find anything that is enough easy to use and easy to automate. Developers find it useful.
I'm sorry if that might seem as a self-ad but I know how annoying is to sync versions...
