[Bug bootstrap/49072] New: Error building the compiler
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49072 Summary: Error building the compiler Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: critical Priority: P3 Component: bootstrap AssignedTo: unassig...@gcc.gnu.org ReportedBy: jose.pascual-guti...@1-act.com I downloaded from one of the mirror sites the following tar balls: gcc-4.6.0.tar.gz gmp-4.3.2.tar.bz2 mpc-0.8.1.tar.gz mpfr-2.4.2.tar.bz2 I decompressed and untarred the files, which resulted in four directories, respectively: gcc-4.6.0, gmp-4.3.2, mpc-0.8.1, and mpfr-2.4.2. I then created the directory ~/gcc4 and I moved gcc-4.6.0 in it. I then changed the names of the directories gmp-4.3.2, mpc-0.8.1, and mpfr-2.4.2 to gmp, mpc, and mpfr, respectively. These three directories, namely gmp, mpc, and mpfr were moved it to ~/gcc4/gcc-4.6.0. In gcc4, I created the directory objdir. So, the directory tree looks like the following: |--gcc4 | |--objdir | |--gcc-4.6.0 | | |--gmp | | |--mpc | | |--mpfr I then proceeded to configure the installation. From ~/gcc4/objdir, I executed “../gcc-4.6.0/configure”. Once the Makefile was created, still from within ~/gcc4/objdir, I executed “make bootstrap”. After about 24 hours of execution, the build failed with the following error message: ../../../gcc-4.6.0/libgcc/../gcc/libgcc2.c:791:1: internal compiler error: Floating point exception Please submit a full bug report, With preprocessed source if appropriate. See http://gcc.gnu.org/bugs.html for instructinos. make [3]: *** [_popcountsi2.o] Error 1 make [3]: Leaving directory ‘/home/Jose.Pascual-Gutierr/gcc4/objdir/i686-pc-cygwin/libgcc’ make [2]: *** [all-stage2-target-libgcc] Error 2 make [2]: Leaving directory ‘/home/Jose.Pascual-Gutierr/gcc4/objdir’ make [1]: *** [stage2-bubble] Error 2 make [1]: Leaving directory ‘/home/Jose.Pascual-Gutierr/gcc4/objdir’ make: *** [bootstrap] Error 2 All the help you can provide will be very appreciated.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49072 --- Comment #2 from Jose 2011-05-20 13:47:38 UTC --- Thank you very much, Jonathan, for your comments. I tried as you suggested. Instead of using mpfr-2.4.2, I downloaded the latest version, namely, mpfr-3.0.1. I also tried with mpc-0.8.1 and mpc-0.9. The same file tree structure and directory names were maintained as in my original message. Also, I simply did a "make" and not a "make bootstrap". The building failed in all cases: make [5]: *** [acos.lo] Error 1 make [5]: Leavimng directory '/home/Jose.Pascual-Gutierr/gcc_compileres/objdir/mpc/src' Making all in tests make [5]: Entering directory ''/home/Jose.Pascual-Gutierr/gcc_compileres/objdir/mpc/tests' make [5]: Nothing to be done for 'all'. make [5]: Leavimng directory '/home/Jose.Pascual-Gutierr/gcc_compileres/objdir/mpc/tests' Making all in doc make [5]: Entering directory ''/home/Jose.Pascual-Gutierr/gcc_compileres/objdir/mpc/doc' make [5]: Nothing to be done for 'all'. make [5]: Leaving directory ''/home/Jose.Pascual-Gutierr/gcc_compileres/objdir/mpc/doc' make [5]: Entering directory ''/home/Jose.Pascual-Gutierr/gcc_compileres/objdir/mpc' make [5]: Leaving directory ''/home/Jose.Pascual-Gutierr/gcc_compileres/objdir/mpc' make [4]: *** [all-recursive] Error 1 make [4]: Leaving directory ''/home/Jose.Pascual-Gutierr/gcc_compileres/objdir/mpc' make [3]: *** [all] Error 2 make [3]: Leaving directory ''/home/Jose.Pascual-Gutierr/gcc_compileres/objdir/mpc' make [2]: *** [all-stage1-mpc] Error 2 make [2]: Leaving directory ''/home/Jose.Pascual-Gutierr/gcc_compileres/objdir' make [1]: *** [stage1-bubble] Error 2 make [1]: Leaving directory ''/home/Jose.Pascual-Gutierr/gcc_compileres/objdir' make: *** [all] Error 2 Thank you very much again for your further comments, Jose

[Bug fortran/49159] New: OpenMP compilation errors
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49159 Summary: OpenMP compilation errors Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: major Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: jose.pascual-guti...@1-act.com I have the following OpenMP Fortran95 test program called test.f90. PROGRAM test USE OMP_LIB, ONLY: OMP_SET_NUM_THREADS IMPLICIT NONE INTEGER, PARAMETER :: numthreds = 4 INTEGER, PARAMETER :: maxnumber = 12 INTEGER :: totalsum, add, number CALL OMP_SET_NUM_THREADS (numthreads) totalsum = 0 add = 1 !$OMP PARALLEL DO & !$OMP SCHEDULE(DYNAMIC,1) & !$OMP DEFAULT(SHARED) & !$OMP PRIVATE(number1,& number2)& !$OMP REDUCTION(+:totalsum) DO nunmber = 1, maxnumber totalsum = add + totalsum + number END DO !$OMP END PARALLEL DO WRITE (*,*) totalsum END PROGRAM test I try to compile it with the command "gfortran -fopenmp test.f90". The compiler returns with the following error message: test.f90:16.24: !$OMP PRIVATE(number1, & 1 Error: Syntax error in OpenMP variable list at (1) test.f90:17.16: number2) & 1 Error: Unclassifiable statement at (1) test.f90:18.8: !$OMP REDUCTION(+:totalsum) 1 Error: Unclassifiable OpenMP directive at (1) test.f90:24.23: !$OMP END PARALLEL DO 1 Error: Unexpectged !$OMP END PARALLEL DO statement at (1) It is clear that the erros are caused by the !$OMP PRIVATE line. It seems that a list of variables cannot be broken in two lines. Had I had !$OMP PRIVATE(number1,number2) & instead of the two lines connected with the & sign, I would have not had any compilation errors. I wanted to try breaking the line, though, because in my codes I have very long lists of private variables. In the previous compiler I used, namely Intel's ifort, I had no issues. Do you have any suggestions when it comes to long lists of private variables? Should I simply have several !$OMP PRIVATE ([var1],[var2],...,[varn]) lines each opening and closing the bracket? Thank you very much
