Could not find MPFR about ibm_qx_mapping HOT 6 CLOSED

Hi,

you should be able to easily get the required depencies by executing

sudo apt install libmpfrc++-dev

in the terminal.

Please let us know, if this solved the issue.

from ibm_qx_mapping.

Thanks for your reply. I tried the command and got this error：

Could NOT find MPFR (missing: MPFR_LIBRARIES) (Required is at leaast version "1.0.0")
Call Stack (most recent call first):
/usr/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:378 (_FPHSA_FAILURE_MESSAGE)
cmake/Modules/FindMPFR.cmake:70 (find_package_handle_standard_args)
CMakeLists.txt:8 (FIND_PACKAGE)

It seems to solve the problem of missing "MPFR_INCLUDES" and "MPFR_VERSION_OK", but still missing "MPFR_LIBRARIES".

Well I don't know why it's not working for you.
Anyway, MPFR is not really required for the mapper, so the newest commit doesn't use it anymore.

Please let us know if this worked for you.

Again, thanks for your prompt reply. I modified the code as the commit, but I got the same result of missing MPFR_LIBRARIES and some other failed on detecting C and CXX compiler features.

I feel that it doesn't make sense...
I think I will keep trying to find other method to install MPFR_LIBRARIES and will let you know if I have any progress as well.

Could you please pull the latest commit and try once more (without MPFR)?

I accidently missed a line in the CMakeList.txt still referring to MPFR, but it's gone now.

from ibm_qx_mapping.

It works!! Thank you!
