Qt mac os x check how to#

It is a fairly large script, but you should already know how to use it: PROTOS = A.proto B.proto I found a great snippet for this task here:

To solve this, we need to pass all proto code generation stage prior to building the resulting source code. If we would generate code for A.proto first (to produce A.pb.h and A.pb.cxx) and feed it to the compiler, it will just fail because the dependency B.pb.h does not exist yet. Imagine you have two contracts, where A is referencing B. You can easily Google a suitable solution, but you need to be aware of one important corner case. Let’s see how can we inject protoc execution into the build process. Code GenerationĪ great example of code generation as a pre-built step is when a C++ project is using Google protobuf. Note: DISTFILES was introduced for the same purpose, but it only works in Unix. When learning existing qmake projects, you may be surprised how different variables can be referenced: \(VAR,\)/openssl/bin/crypto.dll) Control flow statements allow you to include other qmake specification files, control conditional sections, and even call functions. Each variable, in general, holds a list of strings. In a nutshell, a qmake specification is nothing more than a list of variable definitions mixed with optional control flow statements. To build the binary (executable in this case), you need to run qmake first to produce a Makefile and then make (or nmake, or mingw32-make depending on your toolchain) to build the target.

pro file: SOURCES = hello.cppīy default, this will create a Makefile that would build an executable from the single source code file hello.cpp. This is an example of the simplest possible. Qt developers can treat this as a cookbook when starting a new project or can selectively apply some of the features to any of the existing projects with low impact. Readers that are new to Qt can use this guide as a tutorial to Qt’s build system. This guide describes the most useful qmake features and provides real-world examples for each of them.

You are building a standalone library/plugin to be used by other qmake projects.

You are using Qt Creator IDE and most of its features.

You are building a cross-platform Qt-based project.

You might prefer using qmake if the following apply to you: Only a few of them supply dual configuration, e.g., qmake and CMake. Virtually all third-party Qt-based libraries or plugins supply qmake files used to integrate into qmake-based projects seamlessly. Even if you do not intend to use Qt Creator, you may still want to consider qmake as a second build system in case you are building public libraries or plugins. It is likely that CMake support in Qt Creator will be improved over time, and this will be a good reason to issue the second edition of this guide, aimed specifically at CMake. Yes, you can also choose CMake and Qbs build systems for a new project there, but these are not that well integrated. Needless to say, Qt’s default IDE- Qt Creator-has the best support of qmake out of the box. Unlike CMake and Qbs, qmake was a part of Qt since the very beginning and shall be considered as a “native” tool. Qmake is a build system tool shipped with Qt library that simplifies the build process across different platforms.
