I'd like to run a java application on a OpenSolaris machine but this application uses a dll/so that I only have the linux binary. Can it be possible, and this is because I know nothing about the OpenSolaris Brandz feature, that I can deploy the dll on a linux brandz and link to it from a jvm running on the OpenSolaris side?
No you cannot mix Solaris and Linux binaries. What you might do is running the whole on the Linux branded zone.

The situation is this:
I do not have access to a machine running on Linux, just a little embedded platform where I cannot install any IDE (which is in LINUX and is my target), so I got to develop the app from my Microsoft PC.
The question is: should I use Microsoft libraries? Because I am developing in a Microsoft environment, or should I use Linux libraries? Because my target is Linux?
Applications targeting Windows do not work out-of-the-box in a Linux system (see some discussion here https://superuser.com/a/209736).
You could, however, use a Linux guest from the Windows host, through a virtual machine or even docker.
Also, your "little chip target on which you cannot install an IDE" sounds like an embedded platform. Make sure the architecture on the target is the same as your windows pc x86-64 (intel). Many embedded platforms have a different architecture (e.g., ARM's aarch64). In this case, make sure to use an appropriate cross-compiler that will create code for the target.
I compiled and ran a C++ program using Eclipse on my MacBook Pro. I now need to convert the Unix executable to a windows executable. How do I go about this? Specifally, how do I get this code to run on a Windows machine from the command prompt?
The only way you can get the unix executable to run on a Windows system is using a virtual machine (Something like VMWare or VirtualBox). This isn't REALLY running it on Windows, of course, it's setting up a UNIX system on Windows and running it on that UNIX system.
The executables (and the needed runtime environment) are vastly different between the two systems, you can't just run executables from one on the other.
Your only other option is to setup Eclipse on your Windows system and compile the application there.
You cannot "convert" an executable, you need to recompile for your target system. If you are using a GCC toolchain that is set up for Eclipse and there is no Mac specific code, it should be as easy as moving the project over, setting it up in Eclipse, and recompiling it. If that is too much of a hassle, you can consider setting up a Makefile and using MingW or Cygwin, or even Visual Studio if you'd like. If there is Mac specific code, then you need to look up the appropriate Windows documentation, or use something cross-platform like GTK+ or Qt.
I have an application written in C++ using wxWidgets. How can I compile it for Linux and Unix os like Debian, FreeBSD, CentOS, in Windows?
Thanks!
Not entirely sure if I understood the question, but I think you are asking if you can compile an application for linux using a compiler in the windows environment.
My short answer: No, but.
The but: You may be able to use Cygwin in windows, however I think there is an easier way. If you are uncomfortable with setting up your computer to have multiple partitions and installing linux on at least one of these partitions, you can use VirtualBox, VMWare, or similar virtualization software to "install" linux on your windows machine. From there you can set up build environments and such. As for how, I would leave your windows build as is, but then in create a Makefile for Linux (or use CMake to replace both your windows-specific builder (the vsproj if using visual studio, etc) and linux-specific builder (make)) so that your source will compile both on windows and linux without having to modify the actual code or project.
i would recommend to use CMake as build system
I have neved did a cross platform development before but the process we currently employ such as doing the development on a Windows machine (as we are mostly a Windows shop) and then actually building the binaries on a Solaris box looks a bit convoluted to me.
Can you recomend me a cross compiler so I can limit development tasks to a Windows machine (e.g. building Solaris binaries (.so)), and only use Solaris machine for a testing and deployment.
It would also be great to be able to test a resulting binaries on a Windows machine before (e.g. dependencies b/w binaries) deploying them into the Solaris box, but it looks like I am asking for too much.
Why not use a tool like cruisecontrol to build your apps for you simultanously on both platforms. Doing it this way makes it easier to add more platforms in the future.
Failing that you could use cygwin or mingw to build on windows only for development, then build your real distribution on solaris.
I don't know anything about cross compilers as I've never used therm, sorry
I don't know if a Windows/Cygwin hosted compiler that targets Solaris exists as a ready-to-use product, in any case some googling around didn't give any results.
However, I do have some experience with the creation of gcc&friends based toolchains that run under Cygwin and target Linux platforms (i386 and ARM). When your target is Linux, there's a tool called crosstool that automates a lot of the work that needs to be done, so basically with a reasonably fast machine, a healthy dose of patience and a (longish) evening of build runs you'll be able to build a usable toolchain.
Although in theory you could mimic what crosstool does to create your own cygwin to solaris toolchain, I'm afraid that in practice it may just not be worth the effort.
I have a small piece of code that works as a plugin for a larger graphics application. The development platform is Qt with c++ code. I've managed to build a .so, .dylib and .dll for linux, MacOS and Windows respectively, but to do so I had to have a machine running each operating system (in my case, running linux [ubuntu] gcc natively, and windows MinGW and MacOS XCode gcc in virtual machines).
Is there a way to build for all 3 platforms from one? I beat my head against this problem a while back, and research to date suggests that it's not easily (or feasibly) done. The code only needs to link against a single header that defines the plugin
API and is built from a fairly basic Makefile (currently with small variations per platform).
You should have a look at crosscompiling.
You basically build a compiler that (on your current plattform) will output binaries for your desired platforms.
Try this link about doing it on linux, for windows, with QT
Better late than never, I just came across IMCROSS
It looks quite promising!
For Linux it is fairly easy to setup or even download a virtual machine using VMWare for instance. Getting OSX to run on VMWare is somewhat tricky but possible.
Running VMWare and sharing a directory on a local drive you can even compile for the different platforms using the same exact files.
There is somewhere a cross-compiler for OSX but I wouldn't trust it to be of great quality.
