Ubuntu standard C++ libs documentation?

[kahumba]

Hi,
I know how to install the C++ Gtk+ docs (libgtkmm-2.4-doc) and browse them at
/usr/share/doc/libgtkmm-2.4-doc/reference/html/classes.html

is there such a package for Ubuntu for the standard C++ classes (libs) like <iostream> etc?

I know but my internet connection is so shaky that I really need an offline version of the docs, preferably a good one, I thought it's possible just like with the gtkmm package mentioned above.

I do not know of any; you could always download this tutorial in its PDF format.

Thanks, I guess I'll use that one.
I found libstdc++6-4.4-doc which can be browsed at
/usr/share/doc/gcc-4.4-base/libstdc++/html/index.html
but it seems to "raw" for me.

I am having similiar problems trying to run gcc and g++ on a recent install of gcc 4.2.2.
When running the good 'ol hello.c, many errors are returned.
gcc : hello: no such file or directy
hello.c:1:22: error isotream.h: No such file or directory
hello.c: in function 'main':
hello.c:4 error: 'cout'undeclared (first use in this function)
hello.c:4:error: (Each undeclared identifirer is reported only once
hello.c:4:error: for each function it appears in.)

in what directory file should the c and cpp library headers be located?

Thanks

Alex,

If you have installed the g++ package, you should have no issues with locating header files. I would offer the following for your hello-world woes:

1. You need to include the <iostream> library. Not the <isostream> library to do stuff with cout and the like.

2. You should probably name the file hello.cpp or hello.cxx to let gcc know that it is a C++ file, not a standard c file.

3. You should probably compile with g++ instead of gcc.

Regards.

Thanks for your follow up.
1. the isostream was a typo when composing the forum question. it is entered as iostream in the hello.cpp file.
2. Yes, it was named as hello.c for gcc run and hello.cpp for g++ run
3. it is accurate to assume all c files must compile with gcc and all cpp must compile with g++. Will g++ recognize filename.c code?

[alexkaz]

no. 3: should be IS it ???

So, we meet again... 8)

Yes, g++ should recognize filename.c code.
Actually, the contents of the files is more important than the filename (but it is a good habit to use the .c extension for C code and .cpp for C++ code).
gcc can only compile C code (ex: printf), while g++ can compile C and C++ (ex: cout).

P.S.: You can use the "edit" button in the bottom-right of your post to correct typos. ;)
