I'm setting up some codes in the bash/Ubuntu/Xming environment on a Windows machine (a new Dell laptop, 64 bit). One item in particular that I'd like very much to get running is seg2segy, as I'm not aware of too many other options for converting SEG2 to SEGY. I'm definitely not very proficient at compiling, but I've been stuck on this for several days and would be glad for suggestions. I've installed a number of libraries to get this to compile, via apt-get, and do get it to (seemingly) compile. But the executable doesn't actually work. I've got two main options at this point: If I compile with "gcc -m32 seg2segy.c -Bstatic -o seg2segy", and then attempt to run the executable, I get this message " -bash: ./seg2segy: cannot execute binary file: Exec format error". My understanding is that this indicates that the executable was compiled for an incorrect type of system. But I don't entirely understand what that means in this case. I'm not too sure whether I ought to be using the -m32 flag, but that's what's indicated by the note in the Makefile. If I use that flag, in order to avoid a compile error regarding "fatal error: sys/cdefs.h: No such file or directory", I need to install either/both of g++-multilib or libc6-dev-i386. If I compile with "gcc seg2segy.c -Bstatic -o seg2segy" (same as above, just without the -m32 flag) then I get an executable that runs, but that rejects the SEG2 files I've tested it on, giving this message (I'm including my command): > ./seg2segy 329.dat 1 Using default header word mappings. File 329.dat, Data Format Revision: 1, Number of traces: 3 Not a SEG-2 trace header. Can not process 3a55 (line 740) I've tested on a few SEG2 files, including the one that comes with SU in the ThirdParty directory, with the same result. Thank you very much for any suggestions on this. Seth -------------- next part -------------- An HTML attachment was scrubbed...

Once in .su format you can convert to segy easily. I downloaded,? compiled sioseis (gfortran) and ran its conversion options. The following code is taken from inside a "for-loop" that works over many files, where each file name is an indexed element ($i) of an array of file names. For example, $file_name[$i] represents the "ith" element of the array of file names ( strictly @file_name). So if you are not familiar with the perl syntax, just replace $file_name[$i] with a single file name. The only catch is that sioseis expects SEG2 file names to have a suffix = ".DAT".? My seismograph outputs ".dat" files that have to first be converted. A second "gotcha" is that I usually have to run 'segyclean' on the output. In any case, it you need a quick conversion, just send me the files and I can send them back converted.? I work on 64-bit machines under CentOS7. sioseis << eof procs seg2in diskoa end seg2in ffilen $file_name[$i] lfilen $file_name[$i]end end diskoa opath $file_name[$i].su ofmt 1 format su end end end eof Cheers, Juan On 4/9/2018 4:48 PM, Haines, Seth wrote: > Hi all, > ? ?This isn't exactly an SU question, but seg2segy is among the > ThirdParty codes, and I'm hoping that someone here may be able to > provide some suggestions. > > ? ?
