I have now and it works just fine... :-)
Earlier today Greg Nutt (spudmonkey at racsa.co.cr) started things
off and got a fair way along. I then took his work and finished
it. Attached you can find a patch to compile and install STLport
with uClibc and a simple test app that is setup to compile and
run vs both gcc and uClibc... libstdc++ weighs in at 400k, which
is a bit heavy for my tastes, but it seems to work just great...
$ ldd ./test
libstdc++.so.0 => /usr/i386-linux-uclibc/lib/libstdc++.so.0 (0x0x40006000)
libc.so.0 => /usr/i386-linux-uclibc/lib/libc.so.0 (0x0x4006c000)
libpthread.so.0 => /usr/i386-linux-uclibc/lib/libpthread.so.0 (0x0x4009e000)
libm.so.0 => /usr/i386-linux-uclibc/lib/libm.so.0 (0x0x400af000)
ld-uClibc.so.0 => /usr/i386-linux-uclibc/lib/ld-uClibc.so.0 (0x0x40000000)
$ ./test
hello from a global constructor
hello from a normal constructor
hello from test 1
hello from test 2
hello from test 3
Cool, things seem to be working!
goodbye from a normal destructor
goodbye from a global destructor
$ cd /usr/i386-linux-uclibc/lib
$ ls -lh libstd*
