[Merged, Moved] Compile problems on Ubuntu and OS X

[kyleplattner]

I have a very basic application that just loads a qml file. Here is my error, any thoughts:

@Running build steps for project harvest...

I get this output error in Ubuntu. Any ideas?

Probably the .pro file mentions non-existing files?

[kyleplattner]

Contents of my .pro file:

@include(../src.inc)
QMAKE_CXXFLAGS_DEBUG += -fprofile-arcs
-ftest-coverage
QT += declarative
TARGET = harvest
SOURCES += main.cpp
harvest.cpp
HEADERS += harvest.h
CONFIG += no_fixpath
RESOURCES = resources.qrc

harvest.path = /usr/bin/harvest
harvest.files = ../../build/dist/harvest
INSTALLS += harvest@

Here is the directory listing for the project folder:

build build.inc harvest.pro harvest.pro.user src

[lycis]

Usually the output line

@make[1]: *** No rule to make target `main.cpp',...@

is an indicator that you don't have a main.cpp file or it is not writeable or not in the directory.

Maybe you could provide a little bit more information on your project?

[kyleplattner]

What sort of information would be helpful?

As I keep looking it seems to have something to do with a main.o file which doesn't exist in my folder structure. Where can I get this?

[lycis]

Well as browsing through the forum I suppose this is the same topic as "here?":http://developer.qt.nokia.com/forums/viewthread/3279/

I assume it's better to talk about this topic there because missing declarations in the .pro file would have been my next guess and it looks like this is not a platform dependant issue!

[goetz]

The paths to your main.cpp and harvest.cpp and other SOURCES and HEADERS are wrong. They must be either

• absolute path (not recommended)
• or relative to the directory where your .pro file is in

To achieve the latter, go to a shell, enter the directory where your .pro file lives and list the source file on the command line like this:

@
ls -l src/main.cpp
@

If you see a result, the argument to ls is what must go into your .pro file.

Also, qmake should have printed a warning on the console:

@
$ qmake
WARNING: Failure to find: main.cpp
WARNING: Failure to find: harvest.cpp
WARNING: Failure to find: harvest.h
@

[lycis]

The .o files are generated by your compiler.

Are your source files stored in the same directory as your .pro-file? If not, this might be kind of problem, because your project file declares it's sources to be

@SOURCES += main.cpp
harvest.cpp@

This usually means that these files are in the same folder as the .pro-file.

[kyleplattner]

I am using both OS X and Ubuntu and having issues on each. I tried both areas since with a different os in each because I wasn't for sure where the best location was for it.

[kyleplattner]

They are not. I will do some experimenting.

[goetz]

I've merge the two threads since they are about the same problem and moved to the Tools forum, because it's more a qmake question.

[kyleplattner]

Thats fine. Still having some issues... and still poking around.

[lycis]

An easy solution for the SOURECS definition is to declare it as:
(notice that I assume that your sources and headers are located in src)

@
SOURCES += src/main.cpp
src/harvest.cpp
INCLUDEPATH += src/
@

With INCLUDEPATH qmake will configure make to find all header files within the src folder because this will also cause some trouble if they are not found.

I hope this helps you a little bit.

On my Mac the mkspec is per default macx-xcode. To compile the project in a console use qmake -spec macx-g++ && make. This works for me.

[kyleplattner]

That change rendered this error:

[kyleplattner]

My problem had to do with a shadow build and installing unit test files.
