Missing "HISTORY_STATE" and "history_get_history_state()" symbols

[Ed K]

I am attempting to compile SAC from source (sac-102.0.tar.gz) and am seeing some undefined symbols, HISTORY_STATE and history_get_history_state(), referenced in history.c in the function length_history. The file History.doc refers to a file called history.h but there is no such file. It probably should read sac_history.h but that file doesn't define those symbols either. I wonder if I have a defective tarball. Any thoughts?

Ed,

I think you will have a better chance of getting useful help if you paste in the error and its context during the installation along with the computer type and operating system you are using.

Thanks, Stephen and Cliff. I am helping a user of the SAC code to install it on a Penguin HPC running RHEL. At this point configure recognizes some missing libraries so I am running this configure from my build directory to bypass that problem.

../configure --prefix=${INSTALL} \
 CC=gcc CXX=g++ \

--disable-editing

Configure seems happy so I run "make" which ends with the errors I mentioned. The gcc version is 8.5.0 (old, but its version doesn't appear relevant):

The symbols HISTORY_STATE and  history_get_history_state() appear nowhere in the tarball that I have, which led me to wonder if I mine might be messed up.

Thank you, Stephen and Cliff, for your replies.

I am helping a SAC user install v. 102.0 from the source tarball
sac-102.0.tar.gz on a Penguin HPC running RHEL. The current configuration
is using gcc 8.5.0, a pretty old version but the compiler version doesn't
appear to be relevant.

The configure, which disables editing for the moment to avoid a missing library
runs without complaint:

../configure --prefix=${INSTALL} \
    CC=gcc CXX=g++ \
    --disable-editing

However the make hits an error when it gets to history.c:

The missing symbols, HISTORY_STATE and history_get_history_state, are defined
nowhere in the code that I have which is what made me wonder if I somehow got a
defective tarball. The src/history/History.doc file refers to a file called
"history.h" being added to src/main/sac.c but that is incorrect. I assume that
this is actually "sac_history.h" which I do have (and which carries the internal
label "history.h"), but that file doesn't define those symbols. So it seems that there
are some components that are at a minimum not up-to-date in my copy.

Thanks for your input.
