installation of ocaml: gmp-devel and zeromq-devel needed, even if present in libs and include about qp2

Hello Anthony,

I tried using the dev branch the installation of ocaml works fine now 👍

Thank you a lot for your help !

Hello Matthias, yes, you are right. You don't need root privileges and the dependencies have already been properly installed. Can you try the following? ``` ./configure source quantum_package.rc ./configure --install=all ```

Hello Anthony,

Thank you for your answer.

I deleted the whole folder and ran

git clone https://github.com/QuantumPackage/qp2.git
cd qp2
./configure
source quantum_package.rc
./configure --install=all

But got the same exact error at the installation of ocaml/opam, saying that the packages gmp-devel and zeromq-devel are missing.

I checked the environment and the lib and lib64 folder are in the LIBRARY_PATH and LD_LIBRARY_PATH. Moreover the include folder is in the C_INCLUDE_PATH and CPATH environment variables. Is it enough for opam to resolve the dependencies ?

Hi,
Yes, I agree with you. Setting LIBRARY_PATH and C_INCLUDE_PATH should be enough for opam to detect the installed libraries.

You can try to wipe out everything, log out and in again, and then clone the dev branch. We have improved the installation, and it could work better for you:

git clone https://github.com/QuantumPackage/qp2.git --branch=dev
cd qp2
./configure --install=all

Please let me know if it solves you problem. Good luck!
