--- Comment #17 from rob1weld at aol dot com 2007-06-17 14:07 --- Due to the bugs in mpfr ( http://www.mpfr.org/mpfr-2.2.1/#bugs ) we should probably _require_ a recent version. It would be kind of someone else to make that patch - I am kinda busy at the moment. The section File: mpfr.info, Node: Miscellaneous Functions provides the macros. Mpfr p5 may have bugs in it but it is the newest available so we should require that version at least. Using an old version (without an expect script to print a WARNING: line in the testsuite) will drive people buggy trying to find out why their code is broken when in fact it is the user's library that is needing fixing. Applying these changes can clean a few errors off the testsuite and put us a step closer to a release. Please don't prefer patching the testsuite to skip tests on the basis that the user has an old unsupported version of mpfr. The lines in configure that need changes are: #if MPFR_VERSION MPFR_VERSION_NUM(2,2,0) #if MPFR_VERSION MPFR_VERSION_NUM(2,2,1) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32258

--- Comment #18 from rob1weld at aol dot com 2007-06-17 20:46 --- Page: http://gcc.gnu.org/install/prerequisites.html says: MPFR Library version 2.2.1 (or later) Necessary to build GCC. It can be downloaded from http://www.mpfr.org/. The version of MPFR that is bundled with GMP 4.1.x contains numerous bugs. Although GCC may appear to function with the buggy versions of MPFR, there are a few bugs that will not be fixed when using this version. ... If we want that page to be correct then the MPFR_VERSION_NUM(2,2,0) must be changed to at least MPFR_VERSION_NUM(2,2,1) (mandatory) and the second [MPFR_VERSION_NUM(2,2,1)] should require p5 (good idea). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32258

--- Comment #11 from rob1weld at aol dot com 2007-06-13 08:06 --- The configure script should check the headers against the library version. Two people from gcc.gnu.org and I all got nailed by this. It may bite others with less computer knowledge than ourselves. The bug is this: 1): The configure script needs a sanity check since GCC compiles and works reasonably well with the library / header mixup. 2): It is the GCC configure script that is choosing the wrong headers to match the library it chose. 3a): _IF_ GCC wants /usr/lib/libmpfr.so/.a it should use /usr/include/mpfr.h 3b): _IF_ GCC wants /usr/local/lib/libmpfr.so/.a it should use /usr/local/include/mpfr.h -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32258

--- Comment #12 from rob1weld at aol dot com 2007-06-13 09:32 --- Comment #10 From Andrew Pinski 2007 This is not a bug. Here is the deal, the reporter compiled GCC with the new headers but is using the old library (which is known to be buggy). Comment #6 From Rob warning: MPFR header version 2.2.1-p5 differs from library version 2.2.0. I double checked. Configure is taking it's library from /usr/lib/ and using /usr/local/include/mpfr.h The MPFR docs say: `MPFR_VERSION_STRING' is the version as a string constant, which can be compared to the result of `mpfr_get_version' to check at run time the header file and library used match: if (strcmp (mpfr_get_version (), MPFR_VERSION_STRING)) fprintf (stderr, Error, header and library files do not match\n); So we need something as simple as this added to the main configure script: if (strcmp (mpfr_get_version (), MPFR_VERSION_STRING)) return 1; -- rob1weld at aol dot com changed: What|Removed |Added Status|RESOLVED|VERIFIED http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32258

The GNU/Linux apt-get or aptitude in combination with installing mpfr yourself _might_ have caused a problem with the include files. A standard configuration of mpfr (without any extra configuration options) creates and installs a static library _only_ in /usr/local/lib. When gcc 4.3.0 is configured and built without extra mpfr options it uses the mpfr library in /usr/lib (in preference to the newer one in /usr/local/lib). # ls -l /usr/include/mpfr.h /usr/local/include/mpfr.h -rw-r--r-- 1 root root 34500 May 7 05:29 /usr/include/mpfr.h -rw-r--r-- 1 root staff 34500 Jun 6 17:37 /usr/local/include/mpfr.h # diff -Naur /usr/include/mpfr.h /usr/local/include/mpfr.h (Prints Nothing) # grep -B3 MPFR_VERSION_STRING /usr/include/mpfr.h #define MPFR_VERSION_MAJOR 2 #define MPFR_VERSION_MINOR 2 #define MPFR_VERSION_PATCHLEVEL 1 #define MPFR_VERSION_STRING 2.2.1-p5 I don't know how I got my /usr/include/mpfr.h and /usr/local/include/mpfr.h the same (and neither relevant for /usr/lib/libmpfr*) but I fixed that.
