Premake

Warning

This is a deprecated feature. Please refer to the Migration Guidelines to find the feature that replaced this one.

Since Conan 1.9.0 the premake generator is built-in and works with premake5, so the following should be enough to use it:

[generators]
premake

Example

We are going to use the same example from Getting Started, a MD5 hash calculator app.

This is the main source file for it:

main.cpp

 #include "Poco/MD5Engine.h"
 #include "Poco/DigestStream.h"

 #include <iostream>


 int main(int argc, char** argv)
 {
     Poco::MD5Engine md5;
     Poco::DigestOutputStream ds(md5);
     ds << "abcdefghijklmnopqrstuvwxyz";
     ds.close();
     std::cout << Poco::DigestEngine::digestToHex(md5.digest()) << std::endl;
     return 0;
 }

As this project relies on the Poco Libraries, we are going to create a conanfile.txt with our requirement and also declare the Premake generator:

conanfile.txt

 [requires]
 poco/1.9.4

 [generators]
 premake

In order to use the new generator within your project, use the following Premake script as a reference:

premake5.lua

 -- premake5.lua

 include("conanbuildinfo.premake.lua")

 workspace("ConanPremakeDemo")
     conan_basic_setup()

     project "ConanPremakeDemo"
         kind "ConsoleApp"
         language "C++"
         targetdir "bin/%{cfg.buildcfg}"

         linkoptions { conan_exelinkflags }

         files { "**.h", "**.cpp" }

         filter "configurations:Debug"
         defines { "DEBUG" }
         symbols "On"

         filter "configurations:Release"
         defines { "NDEBUG" }
         optimize "On"

Now we are going to let Conan retrieve the dependencies and generate the dependency information in a conanbuildinfo.lua:

$ conan install .

Then let’s call premake to generate our project:

Use this command for Windows Visual Studio:
```
$ premake5 vs2017  # Generates a .sln
```

Use this command for Linux or macOS:

$ premake5 gmake  # Generates a makefile

Now you can build your project with Visual Studio or Make.
