I want to simply create a reusable "library" for all my future projects that I'm going to be doing in Haxe. I understand there aren't library projects in Haxe, but rather you would just have a collection of source files somewhere and import them as needed. Right?
I've created a new project using Flambe (a Haxe framework) and opened it in the FlashDevelop IDE. It compiles and runs fine.
Now I want to include my library, so I go into the Project Properties under the "Classpaths" tab and set the relative path to my library. It shows up correctly in the "References", and even has the proper code completion when I type "import ...", yet when I compile it fails on the import line stating: 'Class not found : mlg.Engine'
(mlg being the package, and Engine being the class/type)
Is there anything I'm missing?
I think (i may be wrong) that flashdevelop "references" are just autocompletion and not actually passed to the compiler.
I'm not sure what's the "right" way to do it, but I can tell you what I've done (I made a few helper classes for flambe too :P): I simply created a "fake" haxelib, I created HaxeToolkit/haxe/lib/[name]/git, and in [name] i created a .current file that contains "git".
Then on flashdevelop you have to add it as a library (Project settings -> Compiler options -> Libraries).
Note: there are probably other/better ways to do it.

I am currently working on a Node.JS project written in TypeScript using Node.JS Tools for Visual Studio (NTVS). I have a few classes and enums spread out in 3 or 4 files in my project. I am now trying to use the classes defined in those files from my main app file. From my previous work with Node, I know that I would normally need a require call to import each other file/class if I were working with a text editor and the command-line compiler. But, if I open any TypeScript file in my project and start typing the name of a class defined in a different file, Visual Studio shows IntelliSense autocomplete for the class name and its members. This makes me think that the NTVS and/or TypeScript configuration are automatically making all of my classes available project-wide. But if I click the 'run' button, errors are printed to the console because Node can't find the referenced classes at runtime.
This behavior leads me to believe that IntelliSense isn't actually telling me that the classes are available, just that they exist (which seems odd). If I add a require call to the top of the file, and use that imported value instead of the original class name, Node finds the class and I can use it in my code. But this presents two problems:
I must come up with a new name to use for the variable that I import the class into. If I require() it with the original name, Visual Studio shows errors saying that the identifier is a duplicate, because it seems to believe that the original class is available project-wide.
I don't get the autocomplete or type checking in my usage of the class. This pretty much defeats the purpose of using TypeScript.
So, what's the proper way to do this import? Is there a way to make all my classes available globally? If not, what import statements do I need?
This behavior leads me to believe that IntelliSense isn't actually telling me that the classes are available, just that they exist
unless you have top level import or export statement the file is considered a global module and is available project wide : http://basarat.gitbooks.io/typescript/content/docs/project/modules.html
A global module will not work at runtime in node.js
You should use file level modules using import/export and compile with --module commonjs
I'm trying to write a plugin for 3ds max, I went through the entire sdk installation process to the letter as described in the help files.
The problem I'm facing though is intellisence complaining about an invalid macro definition
"IntelliSense: command-line error: invalid macro definition:_CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES_COUNT =1"
I found the definition in project settigs -> c/c++ -> preprocessor definitions as inherited from parent or project default.
I tried disabling the inherited definitions and re-entered them, this time without the space between the name and the = and all works fine so I'm guessing its a typo on their part?
Anyway, I want to change the default project or whatever to not repeat it every time i start a new project. The project is created with a wizard which required me to copy over some files to appear and after which I had to enter the sdk path.
The files I copied are plain text with some fancy extensions and not much in them so I'm guessing the defaults are described in the sdk directory.. somewhere. Does anybody know what kind of a file I'm looking for?
EDIT: I found a file called root.vcxproj_template and it has a section for preprocessor definitions but all it contains is
<PreprocessorDefinitions>_USRDLL;%(PreprocessorDefinitions)</PreprocessorDefinitions>
and no mention of the broken one
EDIT2: in another part of the file there was a path to a property sheet (maxsdk\ProjectSettings\propertySheets\3dsmax.common.tools.settings) which included the faulty definition. I fixed it an no more complaints from VS.
_CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES_COUNT = 1 means that compiler should replace all old C run-time routines such as sprintf, strcpy, strtok with new versions such as strprintf_s, strcpy_s, strtok_s and similar. It goes in pair with following definition _CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES = 1.
More you can find here: (MSDN) https://msdn.microsoft.com/en-us/library/ms175759.aspx. However I tried to use this but without success. It says that you can use this only for statically allocated buffers like char buffer[32], but compilers was still complaining bout unsecure strcpy.
I have a visual c++ project which compiled correctly. Myproject.vcxproj contains a1.cpp, a2.cpp.
Now I'd like to remove a1.cpp from the project and link with the previously generated a1.obj .
I have added $(SolutionDir) to VC++/Library directories
I have added a1.obj to Linker/Input/Additional dependencies
I have got the following error message
LINK : fatal error LNK1104: cannot open file 'a1.obj'
What I made wrong?
I'm using Visual C++ Express 2010.
A (relatively) clean way to do what you seem to be trying to do is to make a library in the same solution, and add it as a reference to the project that will use it.
Right click the project, select "References" then "Add new reference" and then select the library project in your solution.
If you really want to try using the linker properties, note that there is a "Additional Libraries Directory" setting - this will need to be the OutputDir of the project you are trying to import - and is different to the "Additional dependencies" library name (just the lib name without a path)
I have IntelliJ 12 and some groovy code (along with a pile of java code) in a project.
In intelliJ, i can see class A's import of some groovy code, and i have also included the library that has that code.
However, while the package itself is in one colour (for the import), the actual class being imported is in red, which implies an issue of some sort. Hovering the mouse over it reveals no issue though.
When i run a "make" or a "rebuild project" is where the problems start - i get
Groovyc: unable to resolve class com.blah.blah.blah.A
How can i resolve this?
Currently, my project setup is like so:
Under "Libraries" in (Project Structure -> Project Settings -> Libraries) I have:
the jar file with all the groovy code
the src jar file with all the groovy code
In the "Modules" section i have the - well, i don't know what to call it, the column isn't labelled - the library name from the libraries section associated with the src and class files, and the little "export" button beside it is ticked.
Incidentally, opening the class in intelliJ never shows the source code, which given the source is included struck me as weird.
Is there anything else I should need to do?
I've worked this one out, but if anybody knows why groovy cannot be in the "Resource Patterns" list and wants an upvote, do chime in
Oh, right.
I removed the !?*.groovy entry from the list of, um, entries in the File : Settings -> Compiler -> Resource Patterns thingy.
It doesn't seem to matter if "use external build" is on or off for this, but the !?*.groovy; entry cannot be there.
I wonder if anybody knows why?
I had the same problem and had to Add Framework Support and add Groovy to the project to get round this problem.
I created the project using gradle.
I just got your question in my Google results as I had a similar issue. My problem was that I was able to get the groovy code in my IntelliJ 12 project to compile ok, but it wasn't getting wired in properly when I tried to run unit tests within the IDE.
After some investigation, I uncovered that groovy and logback libraries were all set up in the project to be available in the runtime stage of the Maven build of the project, but that resulted in them not being available in the test stage. To fix this, I ended up manually updating the groovy-all and the logback libraries scope from runtime to provided under File->Project Structure->Modules->Dependencies. This allowed me to both compile and test within the IDE while including the Groovy modules as well as the Java modules.
Perhaps you had something similar going on in your project?
Six years later, I also just got this question near the top of my search results.
In my project my Unable to load class 'groovy.text.SimpleTemplateEngine' problem was actually due to a codenarc issue. I was able to resolve the issue by adding the following to build.gradle:
// codenarc version issue work-around
configurations.codenarc {
resolutionStrategy.eachDependency { DependencyResolveDetails d ->
if (d.requested.group == 'org.codehaus.groovy') {
d.useVersion '2.4.7'
}
}
}
I have a set of statically-compiled libraries, with fairly deep-running dependencies between the libraries. For example, the executable X uses libraries A and B, A uses library C, and B uses libraries C and D:
X -> A
A -> C
X -> B
B -> C
B -> D
When I link X with A and B, I don't want to get errors if C and D were not also added to the list of libraries—the fact that A and B use these libraries internally is an implementation detail that X should not need to know about. Also, when new dependencies are added anywhere in the dependency tree, the project file of any program that uses A or B would have to be reconfigured. For a deep dependency tree, the list of required libraries can become really long and hard to maintain.
So, I am using the "Additional Dependencies" setting of the Librarian section in the A project, adding C.lib. And in the same section of B's project, I add C.lib and D.lib. The effect of this is that the librarian bundles C.lib into A.lib, and C.lib and D.lib into B.lib.
When I link X, however, both A.lib and B.lib contain their own copy of C.lib. This leads to tons of warnings along the lines of
A.lib(c.obj) : warning LNK4006 "symbol" (_symbol) already defined in B.lib(c.obj); second definition ignored.
How can I accomplish this without getting warnings? Is there a way to simply disable the warning, or is there a better way?
EDIT: I have seen more than one answer suggesting that, for the lack of a better alternative, I simply disable the warning. Well, this is part of the problem: I don't even know how to disable it!
As far as I know you can't disable linker warnings.
However, you can ignore some of them, using command line parameter of linker eg. /ignore:4006
Put it in your project properties under linker->command line setting (don't remember exact location).
Also read this:
Link /ignore

Update If you can build all involved project in single solution, try this:
Put all project in one sln.
Remove all references to static libraries from projects' linker or librarian properties.
There is "Project Dependencies..." option in context menu for each project in Solution Explorer. Use it to define dependencies between project.
It should work. It doesn't invalidate anything I said before, the basic model of building C/C++ programs stays the same. VS (at least 2005 and newer) is simply smart enough to add all needed static libraries to linker command line. You can see it in project properties.
Of course this method won't help if you need to use already compiled static libraries. Then you need to add them all to exe or dll project that directly or indirectly uses them.
I don't think you can do anything about that. You should remove references to other static libs from static libs projects and add all needed static libs projects as dependences of exe or dll projects. You will just have to live with fact that any project that includes A.lib or B.lib also needs to include C.lib.
As an alternative you can turn your libraries into dlls which provide a richer model.
Statically compiled libraries simply aren't real libraries with dependency information, etc, like dlls. See how, when you build them, you don't really need to provide libraries they depend on? Headers are all that's needed. See? You can't even really say static libraries depend on something.
Static library is just an archive of compiled and not yet linked object code. It's not consistent whole. Each object file is compiled separately and remains separate entity inside the library. Linking happens when you build exe or dll. That's when you need to provide all object code. That's when all the symbol and dependency resolving happens.
If you add other static libraries to static library dependencies, librarian will simply copy all code together. Then, when building exe, linker will give you lots of warnings about duplicate symbols. You might be able to block those warnings (I don't know how) but be careful. It may conceal real problems like real duplicate symbols with differing definitions. And if you have static data defined in libraries, it probably won't work anyway.
Microsoft (R) Incremental Linker Version 9.00.x (link.exe) knows argument /ignore:4006
You could create one library which contains A, B, C & D and then link X against that.
Since it's a library, only object modules which are actually referenced will get linked into the final executable.
Note that one way of getting this warning is to define a member function in a header without the inline statement:
// Foo.h
class Foo
{
void someFunction();
};
void Foo:someFunction() // Warning! - should be "inline void Foo::someFunction()"
{
// do stuff
}
The problem is you are not localizing library C's symbols. So you have a ODR violation when you link in A and B. You need to have a way to make these private. By default all symbols are exported. One way to do this is to have a special linker definition file for both A and B that explicitly mention which files need to be exported.
[1] ODR = One Definition Rule.
I think the best course of action here will be to ignore/disable the linker warnings(LNK4006) since C.lib needs to be part of both A.Lib and B.lib and A.Lib does not need to know that B.lib itself uses C.Lib.
This may not fix your link error, but it might help with your dependency tree issue.
What I do, is just use a #pragma to include a lib in the .cpp file that needs it. For example:
#pragma comment(lib:"wsock32")
Like I said, I'm not sure it would keep the symbols in that object file, I'd have to whip up an example to try it out.
Poor flodin seems frustrated that nobody will explain how to disable the linker warnings. Well, I've had a similar problem, and for years I have simply lived with the fact that several hundred warnings were displayed. Now, however, thanks to the info from Link /ignore, I figured out how to disable the linker warnings.
I'm using Visual Studio 2008. In Project -> Settings -> Configuration Properties -> Librarian -> Command Line -> Additional Options, I added "/ignore:4006" (without the quotes). Now my warnings are gone!
