So 'make all-target-libstdc++-v3' worked but the first time I ran
'make install-target-libstdc++-v3' I got issues related to the feature
of making the output directory read only:


cmorgan@cmorgan-laptop:~/Downloads/crosstool-ng-1.7.0/targets/arm-unknown-eabi/build/build-cc-core-baremetal$

After 'chmod -R u+r' on the output directory I ran the install target
again and the install worked.


I was able to compile a simple app:

$ cat simple.cpp

#include <stdio.h>

class blah
{
 public:
   blah()
   {
    printf("blah\n");
   }
};

int main()
{
  blah();
  return 0;
}


cmorgan@cmorgan-laptop:~/test$
~/x-tools/arm-unknown-eabi/bin/arm-unknown-eabi-g++ simple.cpp
cmorgan@cmorgan-laptop:~/test$ file a.out
a.out: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically
linked, not stripped
cmorgan@cmorgan-laptop:~/test$ ls -l a.out
-rwxr-xr-x 1 cmorgan cmorgan 87429 2010-06-12 22:47 a.out

The output size looks reasonable considering the static linking.
