Static link of cryptopp lib to Qt-app
-
Hi guys,
I want to use cryptopp in one of my projects. As I don't want to use a dll for security reasons, I have to compile cryptopp into my application.
I thought to compile a lib from visual studio and add it as a static lib to my Qt-project.
Unfortunately Qt gives me linker errorscryptlib.lib(cryptlib.obj):-1: error: LNK2038: mismatch detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value 'MDd_DynamicDebug' in main.objI'm using the windows binaries of Qt so it's probably built with /MD
Is it even possible to statically add a lib in my Qt-version without recompiling Qt with /MT ?CU

Hi,
AFAIK, no, however you can build cryptopp statically while still linking to the dynamic runtime, then you'll be able to link it to your Qt application.

I was able to compile 64 bit MSVC 2017 cryptopp v700 using the following pro file.
Note: static library using MDd & MD cxx flags which will solve your original issue, LNK2038 mismatch.TEMPLATE = lib TARGET = cryptopp INCLUDEPATH += .
