Qt Creator on mac osx: c++ headers not being found / boost/shared_ptr.hpp: No such file or directory

[andrinbertschi]

I started using Qt Creator 2.8.2 on mac osx 10.9.4 for sailfish OS application development (Downloaded Qt Creator from https://sailfishos.org)

If I want to compile a sample c++ file including header from boost, the compilation fails showing
"fatal error: boost/shared_ptr.hpp: No such file or directory".

I downloaded boost 1.55.0_2 with brew (brew install boost --with-c++11) and all necessary header files are in "/usr/local/Cellar/boost/1.55.0_2/include/boost" aliasing to "/usr/local/include/boost/".

In my *.pro file, I added

@INCLUDEPATH += /usr/local/include/@

and

@LIBS += /usr/local/lib/@

But this doesn't help, I still can't use boost header files because of

@/app/src/harbour-wlan-keyboard.cpp:41:32: fatal error: boost/shared_ptr.hpp: No such file or directory"@

Do you have any idea whats wrong here?

What is the output of:

ls -lh /usr/local/include/boost

[andrinbertschi]

ls -lh /usr/local/include/boost is pointing to:

/usr/local/include/boost -> ../Cellar/boost/1.55.0_2/include/boost

There are all header files.

[ambershark]

Sorry I actually wanted to see the files and forgot that command would just show the link, can you:

cd /usr/local/include/boost
ls -lh

and post that for me?

Thanks.

[ambershark]

Can you also show me the line of code that is failing, this one:

../app/src/harbour-wlan-keyboard.cpp:41

[andrinbertschi]

Thanks for your support.

I)
@ cd /usr/local/include/boost
ls -lh
@

Here is the output: https://gist.github.com/abertschi/b177e45d6258ef2aed19

II.)

@./app/src/harbour-wlan-keyboard.cpp:41:32: @

is the include of the boost header file:

@#include <boost/shared_ptr.hpp>@

[andrinbertschi]

Btw, my os has Xcode in version 5.1.1 (5B1008) installed.

[ambershark]

Ok I don't see anything wrong so lets test a few more things:

1. If you cat /usr/local/include/boost/shared_ptr.hpp does it work? Do this as the user that is doing the build. Making sure there is no permission issue and that it can actually read the file.

2. Trying adding INCLUDEPATH += /usr/local/Cellar/boost/1.55.0_2/include to your project file. This will test to see if there is some kind of symlink issue or something.

Your symlink looks good, your files look good (no permissions issues I can see), and your include path in your build looks good. It should work so it's weird that it isn't.

[andrinbertschi]

1.) cat /usr/local/include/boost/shared_ptr.hpp looks good. I trigger the build in Qt Creator by "Build Project". The user is the same as I used for cat.

2.) I have already tried to include
INCLUDEPATH += /usr/local/Cellar/boost/1.55.0_2/include
but without success. I get the same error showing "no such file or directory".

I packed the whole project as zip: http://abertschi.ch/default_public/qt/app.zip

Even if I exclude all Sailfish OS specific #includes and just include the boost library in a simple cpp file, the boost header can't be found.

Do you have any other idea ?

[ambershark]

This is really weird. Let's try removing Qt from it and just do:

@
// main.cpp

#include <boost/shared_ptr.hpp>

int main(int argc, char *argv[])
{
return 0;
}
@

Then to build (on command line):

@
g++ -I/usr/local/include -o main main.cpp
@

If that has the problem them we can try to figure it out from there, if not it's something Qt is doing and we can look further into it.

[andrinbertschi]

It's weird indeed. The compilation by command line works just fine.

[ambershark]

Ok, lets make it into a Qt project and see if that works. Assuming you have an empty directory with just main.cpp in it, do

@
qmake -project
@

Then edit the resulting pro file and add:

@
INCLUDEPATH += /usr/local/include
@

Then try:

@
qmake
make
@

See if that builds.

[andrinbertschi]

make shows me
@
make: Nothing to be done for `first'.
@

Although the code was never compiled.

Generated Makefile: https://gist.github.com/abertschi/d77626909a2f0a8d6912

[andrinbertschi]

Just to keep you on track.
The next things I'm going to try are:

• Download Qt 5.3.1 and try to compile with boost headers

• Try to find an older Sailfish Qt release and try to compile with boost headers

@ambershark, I really appreciate your help, thanks a lot. If you have any other idea please let me know.

[ambershark]

Let me see the generated pro file, or you can just try:

@
make distclean
qmake
make
@

If distclean doesn't cause a recompile, then

@
rm *.o
rm main
qmake
make
@

That should force the compile and we'll see what happens.

And boost should work even without compiling it into qt, but adding it to qt would be the better approach. This guarantees compatibility.

[andrinbertschi]

@make distclean @

or

@rm *.o @

don't help. No out files were generated.

@ make: Nothing to be done for `first'.@

All I get is the above message and the Makefile:

@

[ambershark]

Let me see that qt-proj.pro file...

[ambershark]

Ok there's the problem. It is using a subdirs template. Not sure why it would have generated that.

Make a new pro file with this:

@
TEMPLATE = app
TARGET = main
INCLUDEPATH += /usr/local/include .
QT += core

SOURCES += main.cpp
@

Then try building.
