git2r

0.35.0

We first download and unpack the source package, then mask the configure command

wget -qO- https://cran.r-project.org/src/contrib/git2r_0.35.0.tar.gz | \
tar xvfz -
cd git2r
mv configure configure.sav
# create src/Makevars
cd -
 

where we also create Makevars at src/ with the following contents,

# Use C++17 standard
CXX_STD = CXX17

# Compiler flags
CXXFLAGS = -Wall -O3

# Linker flags
LDFLAGS = -shared

# Include directories
PKG_CPPFLAGS = -I/usr/local/Cluster-Apps/ceuadmin/libgit2/1.1.0/include

# Libraries to link against
PKG_LIBS = -L/usr/local/Cluster-Apps/ceuadmin/libgit2/1.1.0/lib -lgit2
 

This is half-way through and issue command libssh2/1.11.0-icelake, and we are now ready to compile

R CMD INSTALL git2r
