Hello!

I try to use the Earthworm-7.10 on Linux armv5tejl platform.
Some modules compiled, some not, but anyway minimal setup works.

There are a setup from:
* startstop module;
* tankplayer module, which takes samples from test_file.tnk and put them into the WAVE_RING;
* decimate module, which takes samples from WAVE_RING, decimate them by 5 and 2, and write back samples, with different SCNL, into the WAVE_RING.

This setup works somehow, because the sniffwave is able to sniff samples of the tankplayer and samples of the decimate.

But decimate module flooding console by to many repeating messages like

mem_circ_queue.c 241 bed98a6c 6c270
mem_circ_queue.c 242 bed98a6c 6c270
mem_circ_queue.c 243 bed98a6c 6c270
mem_circ_queue.c 244 bed98a6c 6c270
mem_circ_queue.c 245 bed98a6c 6c270
mem_circ_queue.c 246 bed98a6c 6c270
mem_circ_queue.c 247 bed98a6c 6c270
mem_circ_queue.c 248 bed98a6c 6c270
mem_circ_queue.c 249 bed98a6c 6c270
mem_circ_queue.c 250 bed98a6c 6c270
mem_circ_queue.c 251 bed98a6c 6c270
mem_circ_queue.c 252 bed98a6c 6c270
mem_circ_queue.c 253 bed98a6c 6c270
mem_circ_queue.c 254 bed98a6c 6c270
mem_circ_queue.c 255 bed98a6c 6c270
mem_circ_queue.c 256 bed98a6c 6c270
mem_circ_queue.c 257 bed98a6c 6c270
mem_circ_queue.c 258 bed98a6c 6c270
mem_circ_queue.c 259 bed98a6c 6c270
mem_circ_queue.c 260 bed98a6c 6c270
mem_circ_queue.c 261 bed98a6c 6c270


This flooding significantly slow down the Earthworm, which makes it unusable in real application.

I have not found direct use of the logit() or *printf() like functions, which print messages of above format. Neither in src/seismic_processing/decimate
*.[ch] files, neither in src/libsrc/util/mem_circ_queue.c.

Please, help me to understand what these messages mean and how to debug and resolve that issue.

Best wishes.

Issue gone "automagically" when I have recompiled Earthworm.
Have no clue what was changed, but now it work fine.

Igor,

Please be sure to source the ew_linux_arm.bash file before you compile the programs.  That should correct some of your issues.

If not, you will need to share the errors from the compile and link steps.
