SuiteSparseQR_C.h: No such file or directory

[nazariyv]

Cannot install your library. Installed SuiteSparse through conda like in the other issue. Did not work. In terms of how to install SuiteSparse through a link you provided in ReadME I do not know, there is no explanation either in your ReadME or their's web-page. Here is the error:

[dswah]

i am seeing the same problem!

[dswah]

OK, i got it working 2 different ways. Note: i am running ubuntu 16.04 and py3.6

1

• conda install -c conda-forge suitesparse
• clone this repo
• locate the freshly installed SuiteSparseQR_C.h file (i used ubuntu's search...)
• change https://github.com/yig/PySPQR/blob/master/sparseqr/sparseqr_gen.py#L18 to point to the directory containing the file
• proceed with manual installation

2

• install libsuitesparse (for apt-get linux) following http://ceres-solver.org/installation.html#linux
• pip install sparseqr

[yig]

@nazariyv What platform are you running on?

[yig]

@dswah I like the second version. Do you have a suggestion for the README?

[dswah]

@yig i guess the README already had the correct information, but it would have been good to clarify 2 things:

• debian/ubuntu linux wants sudo apt-get install libsuitesparse-dev
• doing conda install -c conda-forge suitesparse isnt sufficient because it leaves the necessary files in the wrong place?

perhaps something can be done about the second point. is it possible for PySPQR to look for suitesparse some other way?

[yig]

I pushed a change to the README.

[yig]

It may be possible to have PySPQR look for suitesparse in more locations. Feel free to look into it and propose a change. I don't have time now.

[nazariyv]

@yig same as you, ubuntu 16.04 and python 3.6

Would be nice to see an update on this. Still an issue several years later.

[sgbaird]

Maybe relevant? https://stackoverflow.com/questions/67440802/point-cmake-to-proper-python-header-inside-conda-env

[yig]

This may have been fixed. Can someone please check if it is still an issue?

This may have been fixed. Can someone please check if it is still an issue?

Not yet, still having the issue installing it on windows VS Code Ananconda env.
