Unable to install Package about idea HOT 3 CLOSED

Hi @zamlerd

Based on your error, I guess that the installed compiler on your MAC does not support OpenMP. So you have to install the compile which supports the OpenMP. I recommend you to install the compilers such as gcc or clang from homebrew, and after install them, you have to modify variables in your personal makeovers file (~/.R/Makevars). Here is an example of the ~/.R/Makevars files when using gcc as the compiler on the macOS.

VER=-11.0.3
CC=gcc$(VER)
CXX=g++$(VER)
CFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion
CXXFLAGS=-mtune=native -g -O2 -Wall -pedantic -Wconversion
FLIBS=-L/usr/local/Cellar/gcc/11.0.3/lib/gcc/11

The first line is the gcc version on your computer (type gcc --version on your terminal, you will got the information).And you also have to modify the last line according to your version of gcc.

You can use the homebrew to install it, i.e. brew install gcc

If this does not help, here are also other solutions you can follow: RcppCore/RcppArmadillo#143

Hope it helps!

Hey Ying,

After trying both methods above I am now getting a new error

devtools::install_github('xzhoulab/iDEA')
Registered S3 method overwritten by 'cli':

Error: Failed to install 'iDEA' from GitHub:

Call pkgbuild::check_build_tools(debug = TRUE) to diagnose the problem.

I have devtools installed and can call it

Hi @zamlerd,

Could you please call the function pkgbuild::check_build_tools(debug = TRUE) to see the output?
For example, this is the output of mine:

pkgbuild::check_build_tools(debug = TRUE)
Trying to compile a simple C file
\Running /usr/lib/R/bin/R CMD SHLIB foo.c
gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic -O3 -pipe -g -c foo.c -o foo.o
gcc -std=gnu99 -shared -o foo.so foo.o -L/usr/lib/R/lib -lR

Your system is ready to build packages!

Just want to check if you have installed the tools necessary to compile the package.

Thanks!
