[Speex-dev] Compile flags for sampleenc sampledec.

I suspect I am missing something basic but I do not seem to be able to get the sampleenc and sampledec programs to work together. I think I do not have a compile swtich of flag set correctly.

Backgound information: 

1) 1.0.4 tar package 'make' worked and installed on a mandrake 10.0 linux 

2) speexenc and speexdec appear to work fine. 

3) testenc and testenc_wb work fine, though I notice that compile with gcc testenc.c -lspeex produces a different .bits file than the version made with make. Also, when compiled with gcc, the decoded output is garbled. This makes me think there is a flag I am missing. 

4) test_wb output 16-bit PCM file seems about 1K shorter than the original PCM file. Not sure if this is relevant. 

5) SPEEX_GET_QUALITY does not appear to work for the decoder though documentation lists no limitation. (This has just been mentioned since I joined the group).

6) SPEEX_GET_SAMPLING_RATE does not work well for the encoder in wideband mode 

7) The first bit is documented as the 'Wideband' bit, but in the packets I have looked at, this never seems to get set in testenc_wb in either the nb packet or the following wb packet.

Any suggestions would be appreciated.
