Dear everyone,
I posted a similar question to Stack Overflow there:
https://stackoverflow.com/questions/46907554/binding-with-libiconv-failed-while-compiling-r-devel-on-ubuntu-17-04
and I was suggested to post my question here.
I tried to compile R devel using Dirk Eddelbuettel's recipe (and many variants
of it). Regardless of what I do, I have:
===
[...]/src/main/sysutils.c:794: undefined reference to `libiconv'
[...]
[...]/src/main/platform.c:3052: undefined reference to `u_getVersion_54'
[...]
===
add many other similar lines, similar to the last comment of
http://jtremblay.github.io/software_installation/2017/06/21/Install-R-3.4.0-and-RStudio-on-Ubuntu-16.04
(Of note: the offending line does not contain "libiconv" per se, but instead
"iconv(...)".)
It seems that libiconv is now in libc6. I checked that these packages are
correctly installed, and updated (with Gnome Ubuntu 17.04):
- libc6-dev
- libicu-dev
- build-essential
- fort77
- xorg-dev
- liblzma-dev
- libblas-dev
- gfortran
- gcc-multilib
- gobjc++
- aptitude
- libreadline-dev
- libcurl4-openssl-dev
- default-jdk
- texlive-latex-base
- libcairo2-dev
The configuration step regarding libiconv seems ok:
===
checking iconv.h usability... yes
checking iconv.h presence... yes
checking for iconv.h... yes
checking for iconv... yes
checking whether iconv accepts "UTF-8", "latin1", "ASCII" and
"UCS-*"... yes
checking for iconvlist... no
checking for iconv... yes
checking for iconv declaration...
extern size_t iconv (iconv_t cd, char * *inbuf, size_t
*inbytesleft, char * *outbuf, size_t *outbytesleft);
===
The command iconv -l seems to work fine. This C file compiles with no problem
either:
===
#include <iconv.h>
int main( int argc, char **argv ) {
iconv_t cd = iconv_open( "UTF-8",
"ISO-8859-1" );
iconv_close( cd );
return 0;
}
===
So libiconv seems to be indeed usable, but not during the linking.
Where should I look?
