Use condor_compile to relink a program with the HTCondor libraries for submission as a standard universe job. The HTCondor libraries provide the program with additional support, such as the capability to produce checkpoints, which facilitate the standard universe mode of operation. condor_compile requires access to the source or object code of the program to be submitted; if source or object code for the program is not available, then the program must use another universe, such as vanilla. Source or object code may not be available if there is only an executable binary, or if a shell script is to be executed as an HTCondor job.
To use condor_compile, issue the command condor_compile with command line arguments that form the normally entered command to compile or link the application. Resulting executables will have the HTCondor libraries linked in. For example,
condor_compile cc -O -o myprogram.condor file1.c file2.c ...will produce the binary myprogram.condor, which is relinked for HTCondor, capable of checkpoint/migration/remote system calls, and ready to submit as a standard universe job.
If the HTCondor administrator has opted to fully install condor_compile, then condor_compile can be followed by practically any command or program, including make or shell script programs. For example, the following would all work:
condor_compile make condor_compile make install condor_compile f77 -O mysolver.f condor_compile /bin/csh compile-me-shellscript
If the HTCondor administrator has opted to only do a partial install of condor_compile, then you are restricted to following condor_compile with one of these programs:
cc (the system C compiler) c89 (POSIX compliant C compiler, on some systems) CC (the system C++ compiler) f77 (the system FORTRAN compiler) gcc (the GNU C compiler) g++ (the GNU C++ compiler) g77 (the GNU FORTRAN compiler) ld (the system linker)
NOTE: If you explicitly call ld when you normally create your binary, instead use:
condor_compile ld <ld arguments and options>
condor_compile is a script that executes specified compilers and/or linkers. If an error is encountered before calling these other programs, condor_compile will exit with a status value of 1 (one). Otherwise, the exit status will be that given by the executed program.
