Cannot run the PZ model because of qrupdate not found

[Yinsen Miao]

Hi All, 

I installed LibBi on ubuntu using linuxbrew. Then I tried to run the example code PZ but it gave me the following errors:

~/Documents/libbi/PZ-master$ ./run.sh
Error: ./configure failed with return code 1. required QRUpdate library not found. See .PZ/build_openmp_sse_sm_30/configure.log and .PZ/build_openmp_sse_sm_30/config.log for details
Error: ./configure failed with return code 1. required QRUpdate library not found. See .PZ/build_openmp_sse_sm_30/configure.log and .PZ/build_openmp_sse_sm_30/config.log for details

Then I checked the dependence of libBi using the brew info. Clearly, qrupdate is already in /home/linuxbrew/.linuxbrew/Cellar/qrupdate but libBi cannot find it.

Can anyone have a clue about this error? Thank you in advance!

This looks like you've got qrupdate is installed but the compiler doesn't find it. You could try setting LDFLAGS and see if that makes a difference:

$ export LDFLAGS="-L/home/linuxbrew/.linuxbrew/lib"

Alternatively, perhaps try one of the non-linuxbrew install methods.

Dear Sebastian,

I tried your method and it worked!! Thank you so much!! 

Best,
