A few notes:
|
|
|
|
- Most of the uClibc++ development is done against relatively recent versions of
|
|
GCC. Currently that means something in the 4.2 series. The 3 series was great,
|
|
but has a large number of known issues.
|
|
|
|
- If you are looking to statically compile an application, you must compile it
|
|
without the use of either rtti or exceptions. The library should be compiled
|
|
likewise. Since the application will be statically compiled, you may run a
|
|
dynamic library with exception support.
|
|
|
|
- As of version 0.1.11 uClibc+ throws LOTS of warnings when compiling about inline
|
|
functions used but never defined. There warnings are known errors in GCC
|
|
versions 3.3.3 3.4.0 4.0.0 4.1.0 [Bug #21627]. Either ignore these warnings or
|
|
upgrade your compiler. Note that these warnings will exist when compiling software
|
|
as well as the library itself.
|
|
|
|
- uClibc++ is not capable of bootstrapping itself. The library depends upon some
|
|
of the gcc support files and libstdc++ for exception support. Linking in libsupc++
|
|
moves all of the required code into the library so that the GNU library is no
|
|
longer required AFTER COMPILATION. Thus you can build uClibc++ on a development
|
|
system against libstdc++, but when deployed you will not need any of the GNU library
|
|
files.
|
|
|
|
- The debugging option now has an impact on produced code. For now it simply zeros out
|
|
pointers used internally which should never be used, or which are considered to be
|
|
invalidated anyways. This will help track down bugs easier (this change was in result
|
|
of a memory-related error).
|
|
|
|
- The files in the tests/testoutput directory ending in good are used as reference for
|
|
the test suite - this allows a byte-for-byte comparison of the output of the streams
|
|
library, and so on.
