fatal error: 'minimum_ellipsoid/khach.h' file not found about volesti HOT 7 OPEN

@vissarion ..The interface is working fine.. I directly installed all the dependencies via RStudio. I am facing no issues in the installation.

hello @vissarion , this may solve this issue, please look at it

The C++ compiler needs to be told to look at this root path instead of /usr/include. This can be done by setting the CPLUS_INCLUDE_PATH env variable. We have to also include LLVM’s normal include path because this is where it should search first.

#Adjust your llvm and CLT include paths to match your setup
export CPLUS_INCLUDE_PATH=/usr/local/opt/llvm/include/c++/v1:/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include

This should fix any fatal error: minimum_ellipsoid/khach.h file not found errors.
We might still run into linker errors like ld: library not found for -lxxx The linker also needs to be told to look for libraries in the CommandLineTools/Xcode paths by setting the LIBRARY_PATH env variable.

export LIBRARY_PATH=$LIBRARY_PATH:/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/lib

Make sure to add these export statements to the .bash_rc, .zshrc, .bash_profile, or whatever shell you use, to make these adjusted environment variables available in all terminals.

I found the issue. See:

I then ran into another issue where colamd.h was being found in /usr/local/include instead of src/external/lpsolve/headers/include so I rewrote the following two lines

as

LP_SOLVE_CPPFLAGS=-I../../headers/include \
                  $(CPPFLAGS) \
                  -I$(R_INCLUDE_DIR) \

Afterwards I followed the following steps to install the package

1. running in R console install.packages(c('rcmdcheck', 'devtools', 'Rcpp', 'RcppEigen', 'BH', 'testthat', 'downloader', 'xfun')) followed by setwd("/Users/rjian/volesti/cran_gen")
2. running genCRANpkg.R
3. running in R console setwd("/Users/rjian/volesti/cran_gen/cran_package") followed by devtools::install()

The context for running these steps instead of the instructions in the docs

Rscript -e 'Rcpp::compileAttributes()'
    R CMD INSTALL --no-multiarch --with-keep.source .

is that

In retrospect maybe I should've just tried installing from master instead of develop, I'm not even trying to make any changes to the R interface.

from volesti.

Indeed the correct way of building and running the R interface is via genCRANpkg.R and this should be updated in the docs.

can i also work on this issue

from volesti.

I am able to install the complete interface. I am using Rstudio version 4.22
