Software packaging problems

[abigcoder04]

Dear bro， After I successfully installed the qp software in the directory /usr/local/qp/qp2 and successfully tested the case, I now want to package the qp and put it in the directory /root I specified, and delete the installed qp package in the directory /usr/local/qp/qp2 at the same time. Now I go to the /root directory to directly test the qp software. He will prompt me to find some files in the/usr/local/qp/qp2 directory. How to solve this problem. I installed ocaml using ./configure -i ocaml, I recompile directly in the/root directory, and the error is as follows：

System file /usr/local/qp/qp2/external/ocaml-bundle/bootstrap/bin/ocamlc, which package ocaml-bootstrap.4.11.1 depends upon, no longer exists. The package has been marked as removed, and opam will try to reinstall it if necessary, but you should reinstall its system dependencies first. Finished, 0 targets (0 cached) in 00:00:00. Exception Sys_error("/root/pkg/qp-2.1.2-hpc/qp2/ocaml/qptypes_generator.byte: No such file or directory"). Compilation unsuccessful after building 0 targets (0 cached) in 00:00:00.

I would like to ask how to package the qp software to run in other directories or on other machines. I hope to get your reply.

Hello, if you install OCaml with ./configure -i ocaml, you can't move the installation because some absolute paths are written in files. I have been looking for a solution for a long time and the best I found is to use a singularity or docker container.

Dear scemama, How to solve this problem with using a singularity? Can you tell me how to solve this problem？I hope to get your reply!

[scemama]

See discussions of issue #180. There are links to singularity build files which could be good starting points for you.

I took a closer look and found that the developer did not use the automatic build method to install ocaml and reported an error while making. Later, the following comment area gave him a solution that still used ./configure -i ocaml.

[abigcoder04]

Hello, if I finished packaging, I re-download install ocaml package path is feasible with ./configure -i ocaml?

[scemama]

Hello, it should work.

[abigcoder04]

Thank you for your answers, scemama!

hello, scemama! I tried retesting qp on paths other than the installation path, and I have removed the qp package for the installation path, and I tried rerunning. / configure -i ocaml on other paths. The following errors were encountered:

[ERROR] System file /root/install/qp2-2.1.2/external/ocaml-bundle/bootstrap/bin/ocamlc, which package ocaml-bootstrap.4.11.1 depends upon, no longer exists. The package has been marked as removed, and opam will try to reinstall it if necessary, but you should reinstall its system dependencies first.

hello, scemama! I tried to package the installed qp and move it to another server and modified it. The path problem in the /bin directory getopt-sample, ocamlbuild, ocamlbuild.byte, ocamlbuild.native. And I also modified the path problem in the /etc directory 00.qp_root.rc, and changed it to the directory where I want to run the currently packaged qp. At this time, I execute ./bin/qpsh can enter the encoding mode of qp. But i can't execute qp create_ezfio -b 6-31g hcn.xyz -o hcn, the system can not recognize. I want to ask if there are other places where the path I have not changed. I hope to get your reply.

Hello, if the qp command is not recognized, it is that the quantum_package.rc file has not been sourced in the current bash. Can you tell more about "the system can not recognize"? Can you send the error you get?

[abigcoder04]

I currently package the qp package under the installation path to other paths, and delete the successfully installed qp package under the installation path. Then I have modified the path problems in getopt-sample, ocamlbuild, ocamlbuild.byte, ocamlbuild.native and 00.qp root.rc under the new directory qp root directory, and then I execute source quantum package.rc. I then execute./bin/qpsh to get into qp encoding mode, and then I execute qp create_ezfio-b 6-31g hcn.xyz-o hcn to get into trouble. Normally if I execute the hcn.xyz example, I execute qp create_ezfio-b 6-31g hcn.xyz-o hcn to generate the hcn file, but in this case the error: bash : qp_create_ezfio : command not found

Qp software package to run on other machines, is it in addition to these files I changed the directory problem, there are other files in the directory problem I need to modify together ?

hello, scemama! After I reinstalled ocaml in the new directory, I tried to re-make qp, and the final error of make was as follows :

File qptypes_generator.byte I have generated in the installation directory, packaged to run under other machines encountered this problem, I would like to ask how this file error should be resolved. I hope to get your reply.
