------- Comment #7 from jvdelisle at gcc dot gnu dot org 2006-10-27 22:13 ------- Using gfortran: I get AOK, no infinite loop. See information that follows.
Using built-in specs. Target: i686-pc-linux-gnu Configured with: ../gcc43/configure --prefix=/home/jerry/gcc/usr --enable-languages=c,fortran --disable-libmudflap --enable-libgomp --enable-maintainer-mode Thread model: posix gcc version 4.3.0 20061025 (experimental) I built blas and lapack at -O3 I compiled testcase.f with -O3 I used the link line used in Comment #1. The test program compiled, linked, and executed AOK on i686-linux I am using ranlib 2.17 and ar 2.17 The next questionis what tool versions are you using. I also used the make script from the lapack distribution with make.inc as follows: #################################################################### # LAPACK make include file. # # LAPACK, Version 3.0 # # June 30, 1999 # #################################################################### # SHELL = /bin/sh # # The machine (platform) identifier to append to the library names # PLAT = _gfc # # Modify the FORTRAN and OPTS definitions to refer to the # compiler and desired compiler options for your machine. NOOPT # refers to the compiler options desired when NO OPTIMIZATION is # selected. Define LOADER and LOADOPTS to refer to the loader and # desired load options for your machine. # FORTRAN = gfc OPTS = -O3 DRVOPTS = $(OPTS) NOOPT = LOADER = gfc LOADOPTS = # # The archiver and the flag(s) to use when building archive (library) # If you system has no ranlib, set RANLIB = echo. # ARCH = ar ARCHFLAGS= cr RANLIB = ranlib # # The location of the libraries to which you will link. (The # machine-specific, optimized BLAS library should be used whenever # possible.) # BLASLIB = ../../blas$(PLAT).a LAPACKLIB = lapack$(PLAT).a TMGLIB = tmglib$(PLAT).a EIGSRCLIB = eigsrc$(PLAT).a LINSRCLIB = linsrc$(PLAT).a I copied the resulting libraries to libraries matching the names you used. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29621
