INSTALLATION: Requires gcc (> 4.8.5) - compiles with gcc 5.3.1 (useful for RHEL/CentOS users)

[HenrikBengtsson]

Just wanna mention that RcppAlgos requires something newer than gcc 4.8.5 (see error below), which is the default on the RHEL/CentOS 7 distro. I've confirmed that gcc 5.3.1 is sufficient.

Maybe you could add a note on this in the DESCRIPTION file? It'll help people on RHEL/CentOS.

With

RedHat/CentOS users: If you're on RHEL/CentOS and have CentOS Software Collections (SCL) installed - check with scl --list, you can compile RcppAlgos using one of them. This is what I did on an up-to-date CentOS 7 distro:

## Too old
$ gcc --version | head -1
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39)

## Use a less old gcc version
$ scl enable devtoolset-4
$ gcc --version | head
gcc (GCC) 5.3.1 20160406 (Red Hat 5.3.1-6)

## Now we can compile RcppAlgos
$ Rscript -e "install.packages('RcppAlgos')"
* installing *source* package ‘RcppAlgos’ ...
** package ‘RcppAlgos’ successfully unpacked and MD5 sums checked
** using staged installation
...
** testing if installed package keeps a record of temporary installation path
* DONE (RcppAlgos)

## Done; disable the SCL again
$ exit

## Back too old setup, ...
$ gcc --version | head -1
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39)

## ... but it doesn't matter when it comes using RcppAlgos
$ Rscript -e "packageVersion('RcppAlgos')" -e "loadNamespace('RcppAlgos')"
[1] ‘2.3.6’
<environment: namespace:RcppAlgos>

The error you get with gcc 4.8.5 is:

* installing *source* package ‘RcppAlgos’ ...
** package ‘RcppAlgos’ successfully unpacked and MD5 sums checked
** using staged installation

Hello @HenrikBengtsson,

Thanks for reporting this. I will add this to the DESCRIPTION file in the next release.

Hello @HenrikBengtsson,

I want to make sure I do this right, so I scoured all 15000+ packages on CRAN with the rvest package and only found two occurences requiring a minimum gcc compiler. They are:

• VARsignR
• TexExamRandomizer

I wanted to get your opinion on what the best approach is. With the VARsignR package, they have gcc (>= 4.0) under SystemRequirements and the TexExamRandomizer has ..., A modern compiler (>=gcc-4.9), ... under SystemRequirements. I was thinking about a hybrid like:

• SystemRequirements: C++11, gmp (>= 4.2.3), A modern compiler (e.g. gcc (>= 4.9))

Thanks,
Joseph

Wow, that's an impressive scan. I don't know what's best - you might want to reach out on the r-pkg-devel mailing list - but using "A modern compiler (e.g. gcc (>= 4.9))" looks like a good template. It avoids suggesting that one has to use gcc.

The only thing that complicates how to phrase it is the fact that we don't know the lower version limit, only that gcc 4.8.5 is not enough an gcc 5.3.1 works. Using gcc (>= 4.9) may convey that gcc 4.9.0 is sufficient and then someone with that version might pull their hair to figure out why it doesn't work for them. Maybe: A modern compiler (gcc 4.8.5 is too old; gcc 5.3.1 is sufficient).

If it gets too wordy, one could add an INSTALL.md with free-text comments/notes.

@HenrikBengtsson, I really appreciate your feedback.

I forgot to mention the additional research I did that led me to saying at least gcc version 4.9.

First off, I went straight to Writing R Extensions and didn't find anything promising. I then found a couple of post that talked about version 4.8 in regards to C++11 compatibility. Here is a good one with a very simple reproducible example that backs up the claim that 4.8.x isn't C++11 complete: Is GCC 4.8.1 C++11 complete?. This site has some interesting information as well: https://gcc.gnu.org/projects/cxx-status.html.

Anywho, I will definitely reach out to the r-pkg-devel mailing list. In the meantime I will leave this open.

Again, thanks for your help!

@HenrikBengtsson,

I took your advice and added an INSTALL.md file with the relevant information.

Thanks again for your help.
