I'm trying to install Ipopt on a Linux machine, however I dont have any sudo rights. I think the Lapack installation was succesful (is there any way I can check this?). Due to not having sudo rights, I had to install it in a different location though. What I did was the following:
I assume this installation was succesful. Now in '/volume1/dries/' I cloned the Ipopt repository and inside I ran './configure', which gave the following error
checking for LAPACK... no
configure: error: Required package LAPACK not found.
I think it can't find Lapack because the install location is different from the standard one (which is somewhere in '/usr/local'). I also tried running './configure --with-lapack-lflags="-L/volume1/dries/lapack/build/bin/ -llapack -lblas"', but it also gave an error
checking for LAPACK... configure: error: Cannot link to user-specified Lapack -L/volume1/dries/lapack/build/bin/.
How can this be solved?
The error is resolved by adding the install location to the pkg config path:
Now it can find the Lapack installation.
