    @_ove_ Hey, how r u doing? To keep flex and bison files out of project and source control. Generate the C source files and add it to project. Add flex and bison files to project, but run flex and bison commands separately. Integrate properly with IDE (Qt Creator on Ubuntu 12.04) and source control, so that when I build the flex and bison is called to generate lexer and parser. I obviously want third option, but have no idea how to do it. Please suggest the best option and the way to do it.

    @Gerald-L Part of Boost is header only (without library files), for these parts you do not have to add anything to LIBS. Also there are system wide directories containing header files and libraries which you do not have to specify (/usr/include, /usr/lib).

    @Tiago-M-Pinto said in Link Qt program with DLLs:

    Could it be a compiler version issue?

    @sierdzio already told you that only msvc2017 and 2019 are binary compatible. So recompile your lib with 2107 or 2019 and see if it still crashes - if it is the case take a look at the backtrace to see what goes wrong.

    @filipdns said in SQLite database locked on localstorage example:

    Following documentation, js transactions are suppose to automatically close db.

    Why do you work on DB in JavaScript/QML?
    I think it will made more sense to do the DB work on C++ side and implement a QML/C++ interface to access to the data.
    JS/QML is powerful to create/handle user interface, but to work with data C++ is the better choice!

    ... CONFIG += qwt INCLUDEPATH +="/usr/include/qwt" LIBS += -L/usr/lib -lqwt

    @Conical

    The INCLUDEPATH seems to be correct. At least what you are showing.

    I do not know the test library feature of boost. However, I know that some features require separate compilation which will create libraries. This would be for the regular expression of boost for instance. Those libraries need to be referenced with LIBS statement.

    Hi,

    No there's not. You can use the OpenLDAP library to interact your your LDAP server.

    At some point, there was the Luma GUI application.

    @Ace04 said in Unresolved external symbol _strerror_r error while executing libcurl with QT:

    LIBS += -L"$$PRO_FILE_PWD/dependencies/SSL/lib/" libcrypto.a libssl.a

    Your LIBS lines are wrong.

    Correct would be: LIBS += -L"$$_PRO_FILE_PWD_/dependencies/SSL/lib" -lcrypto -lssl (Add -l, omit lib... and .a.

    Also, convert all backslashes to forward slashes.

    Also, remove all trailing slashes from the paths (INCLUDEPATH and LIBS)

    Regards.

    There should also be a folder with the tests that ran. That's the one I am suggesting to check.

    Note that there seems to be some mixing of forward and backward slash which might explain the failure. Use all forward slashes when giving parameters.
