[SOLVED] How to compile?

Ian D · 07-25-2009, 04:19 AM

I have some source code (which I have compiled before on a different machine). I have just installed Ubuntu and installed several packages - but I seem to be missing at least 1.

I have a folder containing 2 .cc files and 1 .h file

I CD to that folder and type g++ -o filename *.cc
(where filename is the name I want to call the compiled output)

I get a number of errors, but the first is that gtkmm.h cannot be found.

Which package should I install to get gtkmm.h?

On opensuse there are gtkmm2 and gtkmm2-devel packages. Probably you will need both.

Hi,

I have come across the same problem with other files and dependencies, packages not installed and so on. Since you're using Ubuntu you can use the apt-file program which will list all the packages that contain the file(s) that give you the error. First you'll have to install the program using:

Code:

apt-get install apt-file

After that do an update:

Code:

apt-file update

and then you can start using it:

Code:

apt-file search gtkmm.h

which will give you the result:

Code:

libgtkmm-2.4-dev: /usr/include/gtkmm-2.4/gtkmm.h
libgtkmm-doc: /usr/share/doc/libgtkmm1.2-0c2a/FAQ/gettinggtkmm.html

So the package you need to install is libgtkmm-2.4-dev

This way you'll always have a handy tool to assist you with compilation errors.

Kind regards,

Eric

Ian D, you do know, also, that you have to tell the compiler to link the gtkmm libraries, right? Just running "g++ -o outfile *.cc" doesn't include the right flags to tell the compiler/linker about the gtkmm libraries. A simple command line to include the right flags can be found here, but you may want to read more detailed information (which you can probably find in the gtkmm documentation, but I don't use it myself, so I'm not sure).

Thanks Nylex,

I had forgotten the bit about those flags.

On the other machine I have a file to remind me how to compile - but that machine won't boot (hardware problem), so I can't read my handy file.
