Compilation FAQ

This is an informal collection of common compilation problems and their solutions. Please add your solutions whenever you encounter a problem so that other people do not have to reinvent the wheel.

1. A lot of errors along the lines of Vars is not a template or qualified name not allowed. Check whether you compile with the c++11 or c++14 standard (-std=c++11 or -std=c++14) and that your compiler is recent enough to support the option you have chosen.
2. undefined reference to `dgemm_etc. This is a very common error and usually means that blas and lapack aren't included correctly. Usually, adding-lblasand-llapack` to syslibflags in $CHOMBO_HOME/mk/Make.defs.local does the trick.
3. undefined reference to `for_write_seq_lis` etc. This has previously arisen with intel compilers and has been solved by adding -lifcore to the syslibflags in $CHOMBO_HOME/mk/Make.defs.local.
4. A guide to installing on ubuntu is here, kindly provided by Leonard Werneck.
