Hi all,
   I met a series of problems when using stream.
   centOS 7(64). asyn and stream, both them was downloaded in git, so i have no idea about version.

I did£º
makeBaseApp.pl -t example test
makeBaseApp.pl -i -t example test    (I want create the example first)
modify configre/RELEASE(add asyn,sream), testApp/src/xxxSupport.dbd(following), testApp/src/Makefile(following), st.cmd(following).

Answer:
Test example was good, but failed after modify.

My quesiton:
The test(example) worked well when I did not add the stream. Why the message came out,"unknow type ai,aai,..." after add stream.

I did set epicsEnvSet "STREAM_PROTOCOL_PATH" "/opt/test/db" in st.cmd. But it seem that did not work, the PATH was still ".".

Thank you so much
Feng W

Here is some information of mine.
