What are the compiler and linker flags you are using?
After, I write a simple test program
as this:
#include <nanodesktop.h>
#include <iostream>
int main()
{
ndInitSystem ();
using namespace std;
cout << "Hello World!";
return 0;
}
The linker finds undefined references:
[Linker error] undefined reference to `vtable for
__cxxabiv1::__vmi_class_type_info'
[Linker error] undefined reference to `vtable for
__cxxabiv1::__class_type_info'
These are gcc symbols normally defined in libsupc++. Make sure
you explicitly link with it. You need to use gcc (not g++) to
link and specify -lsupc++ last on the link line.
You can see how we build stdcxx and the tests in our nightly
builds here:
http://people.apache.org/~sebor/stdcxx/results/builds/
Pick the platform you want to see and the follow the link
to the build log for the build type you're interested in.
For example, gcc 4.1.1 on Red Hat EL 5.0 in 12d (optimized,
shared thread-safe library, narrow build) is here:
http://people.apache.org/~sebor/stdcxx/results/linux_redhat_el-5.0-em64t-gcc-4.1.1-12d-653293-log.gz.txt
[Linker error] undefined reference to `std::basic_ostream<char,
std::char_traits<char> >& __rw::__rw_insert<char, std::char_traits<char>,
long double>(std::basic_ostream<char, std::char_traits<char> >&, long
double)'
This symbol should be defined in lib/ti_insert_dbl.o. We need
to see the full compile and link line both when you built the
library and the executable.
I have already applied Sebor's patch for
disabling MMAP/MUNMAP and it works.
The strange thing is the undefined reference in
basic_ostream. Have you some ideas about this ?
And... what about the CXXABI symbols ?
Thanks

NOTE:
Under Nanodesktop there isn't a command like
"make", so we have used the test programs in
/etc/config to create a particular homebrew
(i.e. a nd application) that generates
a config.h file.
