[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:

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!

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:

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