Create shared library (.lib and .dll) using qmake and MSVC2015
To create a shared library (.lib and .dll) using qmake and MSVC2015, you can follow these steps:
Create a
.pro
file: Create a new.pro
file or modify an existing one to define the configuration for your shared library. Here's an example:proTEMPLATE = lib
CONFIG += dll
TARGET = YourLibraryName
# Add your source files
SOURCES += yoursourcefile.cpp
# Add any additional dependencies
LIBS += -lSomeLibrary
# Set the output directory for the generated files
DESTDIR = $$PWD/Output
Adjust the
TARGET
andSOURCES
variables to match your project's settings and source files. You can also add any necessary library dependencies to theLIBS
variable.Open the MSVC command prompt: Launch the MSVC command prompt for the appropriate architecture (e.g., x86 or x64). The command prompt sets up the environment variables required for building with MSVC.
Navigate to the project directory: Use the
cd
command to navigate to the directory where your.pro
file is located.Run qmake: Execute the following command to run qmake and generate the makefiles:
qmake -tp vc
This command generates the MSVC project files based on your
.pro
file.Build the project: Use MSVC's
nmake
command to build the shared library:nmake
This command will compile your source files and generate the
.lib
and.dll
files in the specified output directory.Verify the output: Once the build process completes, you should find the generated
.lib
and.dll
files in the output directory specified in your.pro
file.
Make sure that you have MSVC 2015 properly installed and configured on your system before attempting these steps. Adjust the commands and configuration according to your specific project requirements.
Additionally, note that qmake is considered deprecated in recent versions of Qt. It's recommended to migrate to qbs or CMake for more advanced build configurations and better support for different platforms and IDEs.
