jsulm

@Bharth You did not post stack trace.
Did you actually try to debug your app to see where EXACTLY it is crashing? This is first thing to do...

Pablo J. Rogina

@Bharth said in After adding crypto++ lib application is crashing....:

i built crypto700 lib and i added .a file to our Qt project and also headers if i run application is crashing....

In addition to provide the stack trace as asked before, are you using the same compiler to build the library and your Qt project?

Bharth

i used QT command prompt

Bharth

while building boost library i used windows command prompt,,,,and while building crypto++ library i have used qt command prompt

jsulm

@Bharth Please just say whether you used SAME compiler to build both...

Pablo J. Rogina

@Bharth said in After adding crypto++ lib application is crashing....:

while building boost library i used windows command prompt,,,,and while building crypto++ library i have used qt command prompt

Could it be possible you share the actual command/settings used for every build you did (Boost, libcrypto, Qt app)?

Bharth

@jsulm No different for boost i used windows and for cryptoo i used qt command prompt because in windows command prompt im not able to generate .a file

Bharth

@Pablo-J.-Rogina for boost build
............................................................
In command prompt
cd boost-1-68-0
boostrap.bat
b2 toolset=gcc

for crypto++
...................
cd crypto
mingw32-make CXXFLAGS="-DNDEBUG-g2-O3-std=c++11"

Pablo J. Rogina

@Bharth mmm no debug settings for Boost... I'm suspicious that you might be mixing release and debug version of the application and libraries.
