We have a server that compiles some code just fine. I am trying a help someone out in compiling the same code on a 2nd server that we just brought up. I am his system administrator and I am trying to install the necessary packages to compile and link this software. We are using the same Intel compiler on both systems xe_2017-update 1. Here is the error we get when trying to link:

 

ld: /users/ramos/neptune-sandy-test/src/objdir/mod_precon.o: undefined reference to symbol 'dhseqr_'
/lib64/liblapack.so.3: error adding symbols: DSO missing from command line
make[1]: *** [fcst_model] Error 1
make[1]: Leaving directory `/users/ramos/neptune-sandy-test/src/drivers/fcst_model'
make: *** [fcst_model] Error 2
[ramos@sandy1 neptune-sandy-test]$

 

I am not a programmer, just trying to osrt this out. Thank you.

Please show the command line used for linking (or provide the makefile). I suspect that what happened is that -llapack was listed in the command before the object files being linked were named.
