在R中安装ggp​​lot2 / digest时出错

Question

I receive the following error after trying to install ggplot2 which in turn tries to install digest . The session info is pasted below.

sha2.c(88): catastrophic error: #error directive: Define BYTE_ORDER to be equal to either LITTLE_ENDIAN or BIG_ENDIAN
#error Define BYTE_ORDER to be equal to either LITTLE_ENDIAN or BIG_ENDIAN

Has anyone encountered this before?

I encountered this and it appears that it happens because your OS headers don't define BYTE_ORDER. I don't know what Linux distributions omit this, but I solved this by doing

$ wget http://cran.stat.ucla.edu/src/contrib/digest_0.6.3.tar.gz
$ tar zxvf digest_0.6.3.tar.gz

Then edit digest/src/sha2.c and stick the following line in there near the top:

#define BYTE_ORDER LITTLE_ENDIAN

(this is assuming your machine is, in fact, little endian; Intel/AMD processors fall into this category). Then

R CMD INSTALL digest
* installing to library ‘/N/u/glock/sierra/R/lib64/R/library’
* installing *source* package ‘digest’ ...
file ‘src/sha2.c’ has the wrong MD5 checksum

The wrong MD5 checksum is harmless.
