[SOLVED] Statically linking an extremely simple c++ program using g++.

c_moriarty · 04-30-2011, 11:03 AM

This is the file, test.cpp:

Code:

#include <iostream>
using namespace std;

int main()
{
    cout << "Hello!" << endl;
    return 0;
}

This at the command-line:

Code:

[c_moriarty@home Haskell]$ g++ -static -Wall test.cpp
/usr/bin/ld: cannot find -lstdc++
/usr/bin/ld: cannot find -lm
/usr/bin/ld: cannot find -lc
collect2: ld returned 1 exit status

So, I've been searching on Google for an hour. How do I make it work?

Code:

[c_moriarty@home Haskell]$ g++ -static -Wall -o test test.cpp -lm -lstdc++ -lc

/usr/bin/ld: cannot find -lstdc++
/usr/bin/ld: cannot find -lm

Perhaps you're missing some packages. Which version of Fedora are you using and what does the following command say?

rpm -qa | grep -E "glibc|stdc++"

c_moriarty · 04-30-2011, 11:36 AM

Fedora 14.

Code:

[c_moriarty@home Haskell]$ rpm -qa | grep -E "glibc|stdc++"
glibc-devel-2.13-1.i686
libstdc++-devel-4.5.1-4.fc14.i686
glibc-common-2.13-1.i686
glibc-headers-2.13-1.i686
glibc-2.13-1.i686
libstdc++-4.5.1-4.fc14.i686

As a quick test, does it work if you remove the -static flag?

c_moriarty · 04-30-2011, 11:42 AM

Yes, it works fine...

Code:

[c_moriarty@home Haskell]$ g++ -Wall -o testcpp test.cpp
[c_moriarty@home Haskell]$ ./testcpp
Hello!

Nylex · 04-30-2011, 11:45 AM

This suggests (to me, at least) that the static versions of the relevant libraries aren't present on your system. Can you just run

ls /usr/lib | grep libstdc++.a

to check?

c_moriarty · 04-30-2011, 11:46 AM

Code:

[c_moriarty@home Haskell]$ ls /usr/lib | grep libstdc++.a
[c_moriarty@home Haskell]$

That seems strange. I have all the packages installed that I would think you'd have to have installed...

c_moriarty · 04-30-2011, 11:48 AM

They're separate, for some reason... I found it:
libstdc++-static.i686 : Static libraries for the GNU standard C++ library
glibc-static.i686 : C library static libraries for -static linking.

c_moriarty · 04-30-2011, 11:50 AM

Thanks...

Nylex · 04-30-2011, 11:50 AM

Presumably you're missing the other static packages too (like for glibc, the GNU C library). I'm not sure which packages you'll need to install, though, as I don't know how Fedora splits everything. Hopefully another Fedora user will see this thread if you can't manage to work it out yourself

.

c_moriarty · 04-30-2011, 11:51 AM

Code:

[c_moriarty@home Haskell]$ g++ -static -Wall -o testcpp test.cpp
[c_moriarty@home Haskell]$ ./testcpp
Hello!

Cool, glad you got it sorted. Please mark the thread as solved (using the "Thread Tools" at the top).

c_moriarty · 04-30-2011, 11:52 AM

I had to install both of those,
libstdc++-static and glibc-static
