The closest thing I’m aware of is BeanShell.

The equivalent of ./configure in Windows?
I just faced with the same issue and here is what I did, I first installed MinGw using the installation manager (with msys base included). Then I go to C:\MinGW\msys\1.0\ folder in my pc, where msys.bat (to evoke the MinGW shell) and run it. Then on that bash screen, I navigated to the folder that … Read more
The benefits / disadvantages of unity builds? [duplicate]
Very similar question and good answers here: #include all .cpp files into a single compilation unit? The summary seems to be that less I/O overhead is the major benefit. See also The Magic Of Unity Builds as linked in the above question as well.
How to improve Golang compilation speed?
Try go install -a github.com/mattn/go-sqlite3 which will install the compiled-against-Go-1.3 package into your $GOPATH. Right now, you likely have an older version installed under $GOPATH/pkg/ and therefore Go is recompiling it for every build.
What are the stages of compilation of a C++ program?
Are the stages of compilation of a C++ program specified by the standard? Yes and no. The C++ standard defines 9 “phases of translation”. Quoting from the N3242 draft (10MB PDF), dated 2011-02-28 (prior to the release of the official C++11 standard), section 2.2: The precedence among the syntax rules of translation is specified by … Read more
Undefined reference to global variable during linking
Change your z.c to #include “a.h” #include “b.h” #include “global.h” int count; /* Definition here */ int main() { count = 0; functAb(); functBa(); return 0; } From global.h, all your files inherit the declaration of variable count but the definition is missing from all files. You must add the definition to one of the … Read more
What does a semi colon do after a conditional block in C#?
This is a simple question with a simple answer, but I just wanted to add something relevant. Often people understand that it does nothing and particularly for the case that you presented, the semi-colon is an unnecessary line termination. But what is the rationale behind it ? Actually, those empty statements are allowed for statement … Read more
Is the compiler allowed to optimise out private data members?
Possible in theory (along with unused public members), but not with the kind of compiler ecosystem we’re used to (targeting a fixed ABI that can link separately-compiled code). Removing unused members could only be done with whole-program optimization that forbids separate libraries1. Other compilation units might need to agree on sizeof(foo), but that wouldn’t be … Read more
C/C++ How Does Dynamic Linking Work On Different Platforms?
To answer your questions one by one: Dynamic linking defers part of the linking process to runtime. It can be used in two ways: implicitly and explicitly. Implicitly, the static linker will insert information into the executable which will cause the library to load and resolve the necessary symbols. Explicitly, you must call LoadLibrary or … Read more
MinGW c++ compiler zlib1.dll missing error?
I had this same problem, but fixed it like this: I ran the MinGW Installation Manager (e.g. C:\MinGW\libexec\mingw-get\guimain.exe). I navigated to All Packages -> MinGW -> MinGW Libraries. I checked the boxes next to mingw32-libz (dev & dll). I went to Installation -> Apply Changes. Now everything worked properly.
