The problem that bothered me for several weeks, because of my work, I had to compile with the old version of iGraph source code. At present, my R version is 3.5.1 and rtools35 But when compiling iGraph\_ 1.2.3.tar.gz, the following problems always occur. ## I hope someone can give me a way to solve the problem. Thank you very much igraph\_glpk\_support.h:36:18: fatal error: glpk.h: No such file or directory #include \ ^ compilation terminated. make: \*\*\* [C:/PROGRA~1/R/R-35~1.1/etc/i386/Makeconf:208: feedback\_arc\_set.o] Error 1 ERROR: compilation failed for package ‘igraph’ - removing ‘C:/Program Files/R/R-3.5.1/library/igraph’ In R CMD INSTALL Warning in install.packages : installation of package ‘C:/Users/Administrator/Desktop/新建文件夹/igraph\_1.2.3.tar.gz’ had non-zero exit status ---

The problem is that `GLPK` is not installed. Please follow the instructions as outlined [here](https://github.com/igraph/rigraph/issues/490). > > > I am trying to install igraph from CRAN with \`install.packages("igraph")\`, and I… get an error like this: > > \`\`\` > In file included from feedback\_arc\_set.c:31: > igraph\_glpk\_support.h:36:10: fatal error: glpk.h: No such file or directory > #include \ > ^ ~~~~~~~ > compilation terminated. > \`\`\` > > How do I solve this? ---

I want to restore to the R environment 3 years ago. I need to install the current version of iGraph. Do you know where to download the old binary version of iGraph? For example, where can I download the binary version of iGraph 1.2.3? ---

Hmmm, it looks like CRAN archives the source code of older versions but not the binaries. So, you can find the source code here: [https://cran.r-project.org/src/contrib/Archive/igraph/](https://cran.r-project.org/src/contrib/Archive/igraph/) You’ll need to grab the tarball, and then run `R CMD INSTALL path-to-igraph-1.2.3.tar.gz` on it. You will still need to compile the source, though, so you’ll need to install GLPK as outlined above. ---

My computer has installed GLPK, but there are other problems when compiling.
