If you encounter a configuration error and cannot find the required Blas library on your system, this guide should help you.
Hello
I recently tried to install packages on clusters requiring BLAS / LAPACK. Since the clusters are often owned by universities, I have no way of installing libblas-dev sudo i.e. liblapack-dev. So, I installed OpenBLAS and compiled the source files. However, when I installed other packages (meep and scuff-em), I ran into problems because I couldn’t find What blas.

1. Download Fortect and install it on your computer
2. Launch the program and click "Scan"
3. Click "Repair" to fix any issues that are found
in the / bashrc file if you want to install the environment after a normal installation of OpenBLAS packages. And when I then use sh autogen.sh for other install packages, I prefer the option:
sh autogen.sh –prefix = / home / gao477 / packages / scuff-em -v LIBS = -ldl LDFLAGS = “- L / home / gao477 / Downloads / hdf5-1.10.5 / hdf5 / lib -l / home / gao477 / openblas / lib -L / usr / local / lib “CPPFLAGS =” – I / usr / local / include -I / home / gao477 / Downloads / hdf5-1.10.5 / hdf5 / include -I / home / gao477 / OpenBLAS / include “
to a specific path for OpenBLAS packages. However, when I did “make”, I still got the “OpenBLAS not found” error. The details are as follows:
Check PTHREAD_PRIO_INHERIT … yes Usability check of hdf5.h … yes Checking for the presence of hdf5.h … yes Verification tools for hdf5.h … yes Look for H5Fcreate in -lhdf5 … for yes Checking H5LTmake_dataset_double in -lhdf5_hl … yes Search for sgemm _… no Check the availability of ATL_xerbla -latlas in … No Look for sgemm_ in -lblas … No Search everywhere sgemm_ -lmkl … no Search for sgemm _… (cached) no Check with sgemm_ in -lcxml … No Search for sgemm_ on -ldxml … no Check sgemm_ in -lscs … No Checking as sgemm_ in -lcomplib.sgimath … No Search for sgemm_ relative to -lblas … (cached) No Search for sgemm_ für -lblas … (hidden) no configure: error: BLAS not found!
Background I found that hdf5 can be used, but BLAS is not. And I will not know what happened to my resignation. Could you help me find the site? Thanks !

I recently tried to install packages on clusters requiring BLAS / LAPACK. Since the clusters are acquired by the university, I definitely don’t have the privilege to use sudo put libblas-dev and liblapack-dev. So, I installed OpenBLAS to compile the source files. However, when I installed other packages (meep with scuff-em) I ran into problems because none of them were found.
in .file / bashrc to set the environment after a normal installation of OpenBLAS packages. And then when you use sh autogen.sh to install other packages, I have the option:
sh autogen.sh –prefix = / home / gao477 / packages / scuff-em -v LIBS = -ldl LDFLAGS = “- L / home / gao477 / Downloads / hdf5-1.10.5 / hdf5 / lib -l / home / gao477 / openblas / lib -L / usr / local / lib” CPPFLAGS = “- I / usr / local / include -I / home / gao477 / Downloads / hdf5-1.10.5 / hdf5 / include -I / home / gao477 / OpenBLAS / include “
to assign the path to the OpenBLAS packages. However, when I “built” it always showed some kind of “OpenBLAS not found” error. The requirements are as follows:

I found that hdf5 might fire but BLAS might not. And I knew what was wrong with my version. Could you help me find out? Thanks !
