[solved] mingw32-make install doesn't work

goetz

It seem as if the Makefile installs the lib into the regular lib directory of Qt.

Did you check if the files actually have been installed in the target dirs?

I just checked the Makefiles for win32-g++ (MinGW) generated on a Mac OS X box (no definitive answer though), but it seems as if "make install" does nothing here. That means, you will either have to copy the stuff yourself or set the INCLUDEPATH and LIBS variables of your .pro file to the respective paths in your source tree of kqoauth.

Which folders would that be to properly install it?
I put them in C:\QtSDK\Desktop\Qt\4.7.3\mingw\lib but that didn't help.

I also added these two lines in the project-file which didn't help either.

@INCLUDEPATH += ../../lib
LIBS += ../../lib@

goetz

I do not have an SDK installed, so I just can guess.

put the library (.a/.so/.lib/.dll - whatever it is in MinGW) into the same directory were the respective QtCore, QtGui, etc. counterparts live (this may be lib for the .lib and bin for the .dll files, I don't know)
put all header files into the include folder where the Qt headers are located

You'll have to repeat this for every Qt version you install afterwards.

I personally would add the paths of the source directory to the .pro file:

@
INCLUDEPATH += C:/kqoauth-kqoauth/include C:/kqoauth-kqoauth/src
LIBS += C:/kqoauth-kqoauth/lib -lkqoauth
@

It's just a guess, so please adjust the paths if you need so.

Hedge

your paths were right. However the compiler complains that it can't find -lkqoauth

bq. c:/qt/qtcreator-2.1.84/mingw/bin/../lib/gcc/mingw32/4.4.0/../../../../mingw32/bin/ld.exe: cannot find -lkqoauth

The error message is the same even if I use that instead:

bq. LIBS += C:/kqoauth-kqoauth/lib -lkqoauthd0

goetz

What files are in the C:/kqoauth-kqoauth/lib directory?

Hedge

kqoauth.prl
kqoauthd.prl
kqoauthd0.dll
libkqoauthd0.a

goetz

Ah, sorry, the snippet was not complete. This is the correct one (spot the "-L" before the path!):

@
LIBS += -LC:/kqoauth-kqoauth/lib -lkqoauthd0
@

Hedge

The problem remains

@c:/qt/qtcreator-2.1.84/mingw/bin/../lib/gcc/mingw32/4.4.0/../../../../mingw32/bin/ld.exe: cannot find -lkqoauth@

goetz

You should change the second one to

@
-lkqoauthd0
@

The general rule is: If you have a file libxblurb.a then you must specify -lxblurb to the linker.

I found out the LINKAGE-entries in the kqoauth.prf lead to that problem.
The relevant part is this:

@# else, link normally
isEmpty(LINKAGE) {
exists($$PWD/kqoauth.pro): INCLUDEPATH += $$KQOAUTH_INCDIR
else: INCLUDEPATH += $$KQOAUTH_INCDIR/QtKOAuth
LIBS += -L$$KQOAUTH_LIBDIR
LINKAGE = -libkqoauthd0
CONFIG(debug, debug|release) {
windows:LINKAGE = -libkqoauthd0
mac:LINKAGE = -lkqoauth_debug
}
}@

After I changed -lkqoauth to -libkqoauthd0 as you can see I get this error now:

@c:/qt/qtcreator-2.1.84/mingw/bin/../lib/gcc/mingw32/4.4.0/../../../../mingw32/bin/ld.exe: cannot find -libkqoauthd0@

goetz

I would guess, this still puts wrong paths into the library search path.

I would recommend to copy the twitter sample application into a separate directory, do not include the .prf files and adjust the .pro file of the sample as mentioned above. I do not have a running MinGW environment at the moment an so cannot test.

Hedge

I did what you said. It compiles now.
The problem however is that it doesn't display any output. It just ends.

According to the main-function it should call showHelp() which should give some output. So I guess something went wrong again. Any ideas?

Here's the main-function:

@int main(int argc, char *argv[])
{
QCoreApplication app(argc, argv);
QCoreApplication::setOrganizationName("kQOAuth");
QCoreApplication::setApplicationName("TwitterCLI");

QStringList args = QCoreApplication::arguments();

TwitterCLI tAuth;
if(args.contains("-t")) {
    if(args.last() != "-t") {
        tAuth.sendTweet(args.last());
    }
 } else if( args.contains("-a")){
    tAuth.getAccess();
} else if (args.contains("-x")) {
    tAuth.xauth();
} else {
    tAuth.showHelp();
    return 0;
}

return app.exec();

}@

and here's showHelp

@void TwitterCLI::showHelp() {
QTextStream qout(stdout);
qout << "TwitterCLI, version 0.95. Author: Johan Paul johan.paul@d-pointer.com\n"
<< "\n"
<< "Usage: twittercli -[at] <tweet>\n"
<< " -a Request for access tokens.\n"
<< " -x Use Twitter xAuth to retrieve access tokens.\n"
<< " -t '<tweet>' Send <tweet> to Twitter after retrieving access tokens\n"
<< "\n";
}@

Did you step through the debugger? It works for me there.

And watch out: It's a console application, you will not get a window with the message :-)

Hedge

I just tried it. btw. I'm using Qt Creator.
While stepping through it it shows the output (showHelp) but if I simply run it, it shows nothing (not even a qDebug() I set at the beginning of the main-function.

Its the same when I start it from the cmd-window -> no output

congrats to your 2.4k-th post :)

goetz

Ah... damn! the stdout trap on windows! As far as I know you do not have this in the cmd shell of windows, so you'll have to stick to Qt Creator to see this (or just make it a small gui, shouldn't be too hard to make a button for each option and a QTextBrowser for the output)

EDIT: Oh, and thanks for the congrats of course.

Hedge

No, that's all I needed.
I'll implement it straight in my program.
It's working beautiful.
