| Summary | 0000376: libstdc++ LFS support with gcc4.0.0 missing declarations of fseeko64 , ftello64 | ||||||||
| Description |
See below trace. ftello64 and fseeko64 are undeclared and it gets the compiler crying. 1. #undefining _GLIBCXX_USE_LFS is a quick fix, for : include/ext/stdio_sync_filebuf.h : #ifdef _GLIBCXX_USE_LFS if (!fseeko64(_M_file, __off, __whence)) __ret = std::streampos(ftello64(_M_file)); #else if (!fseek(_M_file, __off, __whence)) __ret = std::streampos(std::ftell(_M_file)); #endif 2. or telling -fpermissive (like to the compiler propose it) in the Makefile is another |

I have made upon a anti-LFS-patch which works if you still want to use stdlibc++ with gcc.4.0.0 without Large File Support. Thus it will use good old stdin::fseek, stdin::ftell. It must be a bit less optimized all the same do we need large files onto embedded target :) ? ------------ diff -Nur gcc-4.0.0/libstdc++-v3/./config/io/basic_file_stdio.cc.orig gcc-4.0.0/libstdc++-v3/./config/io/basic_file_stdio.cc --- gcc-4.0.0/libstdc++-v3/./config/io/basic_file_stdio.cc.orig 2005-08-11 17:00:34.000000000 +0200 +++ gcc-4.0.0/libstdc++-v3/./config/io/basic_file_stdio.cc 2005-08-11 17:03:22.000000000 +0200 @@ -70,6 +70,12 @@ #include <limits> // For <off_t>::max() and min() and <streamsize>::max() +// Dumb mode : undefining LFS ! +//$ mercredi 08/10/05 09:03:42 md(root)$ +// +#undef _GLIBCXX_USE_LFS + + namespace __gnu_internal { // Map ios_base::openmode flags to a string for use in fopen(). diff -Nur gcc-4.0.0/libstdc++-v3/./acinclude.m4.orig gcc-4.0.0/libstdc++-v3/./acinclude.m4 --- gcc-4.0.0/libstdc++-v3/./acinclude.m4.orig 2005-08-11 17:03:32.000000000 +0200 +++ gcc-4.0.0/libstdc++-v3/./acinclude.m4 2005-08-11 17:07:45.000000000 +0200 @@ -560,37 +560,38 @@ fi ]) - +dnl $ mercredi 08/10/05 09:03:42 md(root) $ +dnl Dumb mode : no check, no LFS mode leave my alone with it ! dnl dnl Check whether LFS support is available. dnl -AC_DEFUN([GLIBCXX_CHECK_LFS], [ - AC_LANG_SAVE - AC_LANG_CPLUSPLUS - ac_save_CXXFLAGS="$CXXFLAGS" - CXXFLAGS="$CXXFLAGS -fno-exceptions" - AC_CACHE_VAL(glibcxx_cv_LFS, [ - AC_TRY_LINK( - [#include <unistd.h> - #include <stdio.h> - #include <sys/stat.h> - ], - [FILE* fp; - fopen64("t", "w"); - fseeko64(fp, 0, SEEK_CUR); - ftello64(fp); - lseek64(1, 0, SEEK_CUR); - struct stat64 buf; - fstat64(1, &buf);], - [glibcxx_cv_LFS=yes], - [glibcxx_cv_LFS=no]) - ]) - if test $glibcxx_cv_LFS = yes; then - AC_DEFINE(_GLIBCXX_USE_LFS) - fi - CXXFLAGS="$ac_save_CXXFLAGS" - AC_LANG_RESTORE -]) +dnl AC_DEFUN([GLIBCXX_CHECK_LFS], [ +dnl AC_LANG_SAVE +dnl AC_LANG_CPLUSPLUS +dnl ac_save_CXXFLAGS="$CXXFLAGS" +dnl CXXFLAGS="$CXXFLAGS -fno-exceptions" +dnl AC_CACHE_VAL(glibcxx_cv_LFS, [ +dnl AC_TRY_LINK( +dnl [#include <unistd.h> +dnl #include <stdio.h> +dnl #include <sys/stat.h> +dnl ], +dnl [FILE* fp; +dnl fopen64("t", "w"); +dnl fseeko64(fp, 0, SEEK_CUR); +dnl ftello64(fp); +dnl lseek64(1, 0, SEEK_CUR); +dnl struct stat64 buf; +dnl fstat64(1, &buf);], +dnl [glibcxx_cv_LFS=yes], +dnl [glibcxx_cv_LFS=no]) +dnl ]) +dnl if test $glibcxx_cv_LFS = yes; then +dnl AC_DEFINE(_GLIBCXX_USE_LFS) +dnl fi +dnl CXXFLAGS="$ac_save_CXXFLAGS" +dnl AC_LANG_RESTORE +dnl ]) dnl diff -Nur gcc-4.0.0/libstdc++-v3/./configure.orig gcc-4.0.0/libstdc++-v3/./configure --- gcc-4.0.0/libstdc++-v3/./configure.orig 2005-08-11 17:07:54.000000000 +0200 +++ gcc-4.0.0/libstdc++-v3/./configure 2005-08-11 17:09:06.000000000 +0200 @@ -83552,8 +83552,11 @@ # Don't enable LFS with uClibc ;; *) +# Say no to LFS ! :) +# $ mercredi 08/10/05 09:03:42 md(root) $ +# cat >>confdefs.h <<\_ACEOF -#define _GLIBCXX_USE_LFS 1 +#undef _GLIBCXX_USE_LFS _ACEOF esac diff -Nur gcc-4.0.0/libstdc++-v3/./configure.ac.orig gcc-4.0.0/libstdc++-v3/./configure.ac --- gcc-4.0.0/libstdc++-v3/./configure.ac.orig 2005-08-11 17:09:08.000000000 +0200 +++ gcc-4.0.0/libstdc++-v3/./configure.ac 2005-08-11 17:10:03.000000000 +0200 @@ -139,8 +139,10 @@ # For the __streamoff_base_type typedef.
