[Bug bootstrap/40360] New: configure: error: cannot compute suffix of object files: cannot compile

[david dot kirkby at onetel dot net]

First, this bug report is very similar to the closed bug 35693. I could find no
way to re-open that bug report, and in any case this is a different version of
gcc, a different machine etc. 

I believe the 'solution' given there, which involves setting LD_LIBRARY_PATH is
not really the right answer, and instead the code should be fixed. 

LD_LIBRARY_PATH should be used as a last resort - see for example


'Why LD_LIBRARY_PATH is bad'
http://xahlee.org/UnixResource_dir/_/ldpath.html

'The evil LD_LIBRARY_PATH'
http://www.sunmanagers.org/pipermail/sunmanagers/2002-May/014159.html

gcc has been told the location of the library with switches - it should not
need LD_LIBRARY_PATH set. 

This bug comes up time and again. Numerous people find it. Really the code
should be fixed, and not workarounds suggested.

------- Comment #1 from pinskia at gcc dot gnu dot org  2009-06-13 19:14 -------
Actually -rpath is worse than LD_LIBRARY_PATH.  And in this case it is not
GCC's fault for where you installed mpfr/gmp that you need to set
LD_LIBRARY_PATH.
