cannot open source file "Version.h"

[gcstoianowski]

I am trying to build Grid on a cluster with BDW processors using Intel 2019.1.144 icpc and Mellanox HPC-X 2.4.0 (Open MPI 4.0.2a1). A similar build not so long ago succeeded.

I cloned the 'develop' branch:

[gerardo@clx-hercules-027 Grid]$ git branch

• develop

ran ./bootstrap.sh and configured it with ../configure --enable-precision=double --enable-simd=AVX2 --enable-comms=mpi3 --enable-mkl CXX=mpicxx --with-lime=/labhome/gerardo/lime_132_i18 --prefix=/labhome/gerardo/Grid_i191h240

make failed almost immediately due to non-existence of Version.h:

[gerardo@clx-hercules-027 build]$ make V=1 2>&1 | tee make_i191h240.log Making all in Grid make[1]: Entering directory /hpc/scrap/users/gerardo/Grid/build/Grid' make all-am make[2]: Entering directory /hpc/scrap/users/gerardo/Grid/build/Grid' depbase=echo util/version.o | sed 's|[^/]*$|.deps/&|;s|\.o$||';

Here is the config.log file: config.log

I could not find a grid.config.summary file.

I have no idea where to find or how to generate the missing Version.h file.

[gcstoianowski]

I found a workaround, consisting in creating Grid/util/Version.h with a single line:

[gerardo@mngx-orion-01 Grid]$ cat Grid/util/Version.h #define GITHASH "c2c4252a07059b837804cc81507a017fe6064ede"

where the value for GITHASH was obtained from 'git show'.

@gcstoianowski thanks! That was really helpful.

I'm still getting this on develop; I assume bootstrap.sh is supposed to generate this file or something?
