Re: [Rd] Can't build R 3.6.1 or 3.5.3 on Ubuntu 18.04 LTS
Hi, Yes I am aware of it. And yes, I have libicu60 installed. Is it the configure script making a mistake?

Are you aware you can get up-to-date binaries either from PPA or CRAN: sudo add-apt-repository ppa:marutter/rrutter sudo apt-get install r-base-dev and I ran ./configure During "make", I get the following error: platform.o: In function `do_eSoftVersion': /home/user/Desktop/R-3.6.1/src/main/platform.c:3129: undefined reference to `u_getVersion_58' Such linking errors indicate you are not linking against the correct library that you compiled against. In this case, there seems to be a version conflict because you compiled against version 58 of ICU, but Ubuntu Bionic actually has ICU60: https://packages.ubuntu.com/bionic/libicu-dev So the question is how do you end up with ICU58 headers? I am guessing your either installed a custom libicu in /usr/local/, or you upgraded from an older version of ubuntu but haven't upgraded libicu-dev. Either way the solution is to clean up your system and make sure there is only one version of libicu. __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

[Rd] switch to reference counting in R-devel
Baring any unforeseen issues R-devel will switch in about a week from the NAMED mechanism to reference counting for determining when objects can be safely mutated in base C code. This is expected to have minimal impact on packages not using unsupported coding practices in their C code. The transition to reference counting has been in progress for a number of years. Some older notes on this are available at http://developer.r-project.org/Refcnt.html. These may no longer be completely accurate but should give you an idea of what is going on. If you want to test your package under reference counting you can do so by building R with -DSWITCH_TO_REFCNT added to CFLAGS or DEFS in a config.site file. A small number of packages are still using the NAMED or SET_NAMED functions even though this has been discouraged for some time. For now these will not produce errors but also not do anything useful. They will probably be removed before R 4.0.0 is released, so you should look at why you are using them and adjust accordingly. Best, luke -- Luke Tierney Ralph E.
