...kage to the current 2.7.1 rc, I noticed that R decides to use its own bzip2 sources. Looking at configure, I see the test is essentially a strcmp on '1.0.5' from the version-returning function: #ifdef HAVE_BZLIB_H #include <bzlib.h> #endif int main() { char *ver = BZ2_bzlibVersion(); exit(strcmp(ver, "1.0.5") < 0); } but unfortunately, bzip2 returns a different string that includes the date: edd at ron:~/src/debian/R/R-2.7.1.20080621> cat /tmp/bzver.c #include <bzlib.h> #include <string.h> int main() { const char *ver...

...g the included bzlib2 source and using it rather than the system bzip2 libraries and headers. I tracked down the reason to this section of configure: cat >>conftest.$ac_ext <<_ACEOF /* end confdefs.h. */ #ifdef HAVE_BZLIB_H #include <bzlib.h> #endif int main() { char *ver = BZ2_bzlibVersion(); exit(strcmp(ver, "1.0.5") < 0); } _ACEOF That code wasn't working at all because HAVE_BZLIB_H never gets set anywhere, even though the configure script had found the system bzip2 bits. This patch adds it to m4/R.m4 and configure, against 2.8.0. With the patch, R now proper...

...245 Nov 3 10:15 /opt/buildaix/include/bzlib.h Seems a very specific bzip2 library is desired - 1.0.6 - not what the message says! BZ2_version():1.0.5, 10-Dec-2007 /* end confdefs.h. */ #include <stdio.h> #ifdef HAVE_BZLIB_H #include <bzlib.h> #endif int main() { char *ver = BZ2_bzlibVersion(); fprintf(stderr,"BZ2_version():%s\n",ver); /* added by aixtools for debugging */ exit(strcmp(ver, "1.0.6") < 0); } So, my question - is this REALLY needed (v1.0.6) as it may break many locations!

Dear All, zlib has been removed from R-devel src/extra recently, and building R requires zlib >= 1.2.5. Ubuntu 12.04 LTS (also used on Travis CI) only has 1.2.3. This means that the next version of R will probably not available on Ubuntu 12.04. (Unless I am missing something of course.) Which is probably fine, it is almost three years old now. I guess R-core is aware of this. Just wanted to
