Tru64 UNIX 4.0D does not have <stdint.h> or <inttypes.h>. So, it has no int8_t, int16_t, int32_t, ...
Because of this, the following problem occurred: gmake[3]: Entering directory `/opt/build/gcc-4.0.2-objdir/alpha-dec-osf4.0d/libg fortran' /opt/fsw/bash30/bin/bash ./libtool --mode=compile /opt/build/gcc-4.0.2-objdir/gcc/xgcc -B/opt/build/gcc-4.0.2-objdir/gcc/ -B/opt/TWWfsw/gcc402/alpha-dec-osf4.0d/bin/ -B/opt/TWWfsw/gcc402/alpha-dec-osf4.0d/lib/ -isystem /opt/TWWfsw/gcc402/alpha-dec-osf4.0d/include -isystem /opt/TWWfsw/gcc402/alpha-dec-osf4.0d/sys-include -DHAVE_CONFIG_H -I. -I/opt/build/gcc-4.0.2/libgfortran -I. -iquote/opt/build/gcc-4.0.2/libgfortran/io -std=gnu99 -Wall -O2 -g -O2 -mieee -c -o compile_options.lo `test -f 'runtime/compile_options.c' || echo '/opt/build/gcc-4.0.2/libgfortran/'`runtime/compile_options.c mkdir .libs /opt/build/gcc-4.0.2-objdir/gcc/xgcc -B/opt/build/gcc-4.0.2-objdir/gcc/ -B/opt/TWWfsw/gcc402/alpha-dec-osf4.0d/bin/ -B/opt/TWWfsw/gcc402/alpha-dec-osf4.0d/lib/ -isystem /opt/TWWfsw/gcc402/alpha-dec-osf4.0d/include -isystem /opt/TWWfsw/gcc402/alpha-dec-osf4.0d/sys-include -DHAVE_CONFIG_H -I. -I/opt/build/gcc-4.0.2/libgfortran -I. -iquote/opt/build/gcc-4.0.2/libgfortran/io -std=gnu99 -Wall -O2 -g -O2 -mieee -c /opt/build/gcc-4.0.2/libgfortran/runtime/compile_options.c -DPIC -o .libs/compile_options.o In file included from /opt/build/gcc-4.0.2/libgfortran/runtime/compile_options.c:32: /opt/build/gcc-4.0.2/libgfortran/libgfortran.h:194: error: syntax error before 'GFC_INTEGER_1' /opt/build/gcc-4.0.2/libgfortran/libgfortran.h:194: warning: type defaults to 'int' in declaration of 'GFC_INTEGER_1' /opt/build/gcc-4.0.2/libgfortran/libgfortran.h:194: warning: data definition has no type or storage class /opt/build/gcc-4.0.2/libgfortran/libgfortran.h:195: error: syntax error before 'GFC_INTEGER_2' /opt/build/gcc-4.0.2/libgfortran/libgfortran.h:195: warning: type defaults to 'int' in declaration of 'GFC_INTEGER_2' /opt/build/gcc-4.0.2/libgfortran/libgfortran.h:195: warning: data definition has no type or storage class /opt/build/gcc-4.0.2/libgfortran/libgfortran.h:196: error: syntax error before 'GFC_INTEGER_4' /opt/build/gcc-4.0.2/libgfortran/libgfortran.h:196: warning: type defaults to 'int' in declaration of 'GFC_INTEGER_4' /opt/build/gcc-4.0.2/libgfortran/libgfortran.h:196: warning: data definition has no type or storage class /opt/build/gcc-4.0.2/libgfortran/libgfortran.h:197: error: syntax error before 'GFC_INTEGER_8' ... libgfortran/libgfortran.h tries to handle this case: #if !defined(HAVE_STDINT_H) && !defined(HAVE_INTTYPES_H) && defined(TARGET_ILP32) typedef char int8_t; typedef short int16_t; typedef int int32_t; typedef long long int64_t; typedef unsigned char uint8_t; typedef unsigned short uint16_t; typedef unsigned int uint32_t; typedef unsigned long long uint64_t; #endif TARGET_ILP32 is not defined for Tru64 UNIX 4.0D. Rather than the above, why do you use autoconf tests to determine if the above are true and then add them to config.h if not? -- Summary: libgfortran assumes system has int8_t Product: gcc Version: 4.0.2 Status: UNCONFIRMED Severity: normal Priority: P2 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: bugzilla-gcc at thewrittenword dot com GCC build triplet: alphaev5-dec-osf4.0d GCC host triplet: alphaev5-dec-osf4.0d GCC target triplet: alphaev5-dec-osf4.0d http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24391
