Description Jashelle O 2012-07-18 16:50:38 EDT
Description of problem:
McIDAS assigns g77 (part of gcc install) to help in the build. At the last step of the build, there is a g77 compiler error which includes the mnmx.f file: internal compiler error: in gen_reg_rtx, at emit-rtl.c:819. "compile mnmx.for: FAILED"

Version-Release number of selected component (if applicable):
cernlib-g77.x86_64 : General purpose CERN library
cernlib-g77-devel.i686 : General purpose CERN library development package
gcc.x86_64 : Various compilers (C, C++, Objective-C, Java, ...)

All latest versions. 

How reproducible:
I'm not sure but error keeps appearing even when switching to gcc or gfortran

Steps to Reproduce:
1.Compile McIDAS (make ..)
2.Error occurs
Actual results:
./mccomp -g -mysql -g77 -I. -I../netcdf/libsrc -I../hdf/hdf/src -I../hdf/mfhdf/libsrc -I../jpeg -I../libpng -I../zlib -I../tiff/libtiff -I../libgeotiff -I../jasper/src/libjasper/include -I../g2clib -I../bzip2 -c mnmx.for
mccomp: Using default optimizations
rm -f mnmx.o

compile mnmx.for:               FAILED

Expected results:
An actual Build

To investigate further, we will need your mnmx.f file.
