Here are the phases of the scala compiler, along with slightly edited versions of their comments from the source code. Note that this compiler is unusual in being heavily weighted towards type checking and to transformations that are more like desugarings. Other compilers include a lot of code for: optimization, register allocation, and translation to … Read more
Not sure what your level of expertise is, but here are the basics. Below is a linker error from VS 2005 – yes, it’s a giant mess if you’re not familiar with it. ByteComparator.obj : error LNK2019: unresolved external symbol “int __cdecl does_not_exist(void)” (?does_not_exist@@YAHXZ) referenced in function “void __cdecl TextScan(struct FileTextStats &,char const *,char const … Read more
GHC wiki contains an introductory article about STG written by Max Bolingbroke: The STG machine is an essential part of GHC, the world’s leading Haskell compiler. It defines how the Haskell evaluation model should be efficiently implemented on standard hardware. Despite this key role, it is generally poorly understood amongst GHC users. This document aims … Read more
The Visual Studio automatically defines _DEBUG symbol for Debug builds (and NDEBUG for non-debug builds). Another way to do this is to go to the project settings -> configuration properties -> C/C++ -> preprocessor, and edit the preprocessor definitions manually. See also: This answer explains the differences between _DEBUG and NDEBUG in more detail. This … Read more
None of these will allow you to compile PHP with cURL enabled. In order to compile with cURL, you need libcurl header files (.h files). They are usually found in /usr/include/curl. They generally are bundled in a separate development package. Per example, to install libcurl in Ubuntu: sudo apt-get install libcurl4-gnutls-dev Or CentOS: sudo yum … Read more
Unfortunately to be able to use the extension modules provided by others you’ll be forced to use the official compiler to compile Python. These are: Visual Studio 2008 for Python 2.7. See: https://docs.python.org/2.7/using/windows.html#compiling-python-on-windows Visual Studio 2010 for Python 3.4. See: https://docs.python.org/3.4/using/windows.html#compiling-python-on-windows Alternatively, you can use MinGw to compile extensions in a way that won’t depend … Read more
Swift toolchain is still a bit gross, you’ll need to use some temporary workarounds until Apple fixes it (see UPDATES below) Here is a list of items that you can do to keep yourself from going crazy. Slowness caused by immature Swift compiler Change your development workflow using Injection for Xcode. Once you installed the … Read more
This has changed in Xcode 4. Now Apps can be exported from the “Organizer” If you haven’t already, you need to create an Archive. On the menu go to Product -> Archive Once you’re in the Organizer – Archives screen click Share or Distribute… (Xcode 4.3.3 or newer) Then choose the format you want to … Read more
Templated code implementation should never be in a .cpp file: your compiler has to see them at the same time as it sees the code that calls them (unless you use explicit instantiation to generate the templated object code, but even then .cpp is the wrong file type to use). What you need to do … Read more
