Hi,
I tried to use clang from pkgin on both base and base64 (version 14.3.0).
Is clang supposed to work?
I installed clang like so:
$ pkgin up
$ pkgin in clang gcc47
I then tried to compile a small program:
int main(int argc, char **argv)
{
return 42;
}
and got a link error:
$ clang -o test test.c -v
clang version 3.5.0 (tags/RELEASE_350/final)

For comparison, when I build with GCC, it uses a different linker and
slightly different libraries, specifically it seems to us "-lgcc_eh"
instead of "-lgcc_s":
$ gcc -o test test.c -v
Using built-in specs.
