[Coin-ipopt] intel/gnu compiler conflict

[Scott Turnberg]

Hi,
I just built Ipopt on linux and got the error below.  My machine has 
both intel and gnu compilers.  During the build the gnu compilers were 
used for compiling the C++ object files and linking.  The intel 
compilers were used for building the C and fortran object files in ASL 
and HSL.  I'm pretty sure this is not correct and is leading to the 
error.  I reconfigured Ipopt and explicitly told it to use the gnu 
compilers for everything and was able to successfully build it. 
The problem appears to be in BuildTools/coin.m4.  When calling 
AC_PROG_CXX/CC/F77 you are giving different priorities to the intel 
versus gnu compilers in each case.
Hope this helps,
Scott
