When I tried to port the phoneMe feature mr4 to linux-arm, some annoying problems occured as below:

I use the source code of phoneme_feature-mr4-rel-src-b01-20_apr_2009, JDK version is j2sdk1.4.2_15, using gcc-3.4.3-csl-uClibc-0.9.30-softvfp(made by self), and the platform is linux-arm, using Directfb-1.2.9.
Did anyone meet with the same problems before? If so, I'd appreciate it if any valuable information is offered, thanks.

Hi Alex,

Please try to make ConcatenatedStream, BytecodePrintClosure and UnicodeStream constructors non inline and define them in the cpp files. And see if the corresponding errors disappear.

Hi Pavel,

Thanks for your quick reply, and I've tried this already, another 7 more errors like these were fixed, but these 5 errors remained too.

Fortunately, I've found the solution to this issue in a nother page in this forum, the link is below:

It seems that compiling the phoneme mr4 in debug mode always cause this error, and it disappears in product or release mode.

However, instead of modifing the root.make, I change the command "make" to "make product" when compiling the CLDC part, and it works!

I've googled for this issue, the reason of this error may be a bug of the gcc as it says below:
