    <p>I have compiled Ffmpeg (1.0) with newt configuration:</p> <pre><code>./configure --disable-doc --disable-ffplay --disable-ffprobe --disable-ffserver --disable-avdevice --disable-avfilter --disable-pthreads --disable-everything --enable-muxer=flv --enable-encoder=flv --enable-encoder=h263 --disable-mmx --disable-shared --prefix=bin/ --disable-protocols --disable-network --disable-debug --disable-asm --disable-stripping </code></pre> <p>It compiled - no errors - headers and libs (static <code>.a</code>) are in place. (special experimental cigwin, experimental gcc, with no asm options, and no known by ffmpeg platform defines) (yet I have compiled and tested boost on it)</p> <p>Now I try to compile my app. I get next exceptions:</p> <pre><code>../ffmpeg-1.0/bin/lib/libavcodec.a: error: undefined reference to 'exp' ../ffmpeg-1.0/bin/lib/libavcodec.a: error: undefined reference to 'log' </code></pre> <p>My compiler build line looks like this:</p> <pre><code>g++ -static -emit-swf -o CloudClient.swf -I../boost/boost_libraries/install-dir/include -I../ffmpeg-1.0/bin/include -L../boost/boost_libraries/install-dir/lib -L../ffmpeg-1.0/bin/lib \ timer.o \ audio_encoder.o \ audio_generator.o \ video_encoder.o \ video_generator_rainbow.o \ simple_synchronizer.o \ multiplexer.o \ transmitter.o \ graph_runner.o \ cloud_client.o \ -pthread \ -lswscale \ -lavutil \ -lavformat \ -lavcodec \ -lboost_system \ -lboost_date_time \ -lboost_thread </code></pre> <p>So as you see quite complex and I already have all object files compiled and ready... Only one thing left - link it all to ffmpeg (striped from ffmpeg version compiled with boost)</p> <p>Tried adding <code>-lm</code> - no help...</p> <p>Well here my question is - how to get list of libraries ffmpeg linked to (like <code>-lm</code> etc)? </p>

    2. COI think you just put them in the wrong order. You need to add `-lm` to the *end* of the command line, not the beginning.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
