From the glibc FAQ (/usr/share/doc/glibc-2.2/FAQ):
2.35. When recompiling GCC, I get compilation errors in libio.
{BH} You are trying to recompile gcc 2.95.2? After upgrading to glibc 2.2,
you need to apply a patch to the gcc sources, because the fpos_t type and
a few libio internals have changed in glibc 2.2. The patch is at
http://clisp.cons.org/~haible/gcc-glibc-2.2-compat.diff
Actually, I'd rather direct you to: http://gcc.gnu.org/install/specific.html#*-*-linux-gnu It should be noted that at least the patch at http://clisp.cons.org/~haible/gcc-glibc-2.2-compat.diff works even for egcs-1.1.2, which is often more useful than GCC-2.95.2 or 2.96 (generating faster C++ code than 2.95.2, while compiling much faster than 2.96 for my applications). Since this issue is bound to come up for so many people for the next year or two, it would be very helpful if RedHat could release RPMs for GCC-2.95.2 and egcs-1.1.2 that do not conflict with the 2.96 RPMs. The egcs RPMs from e.g. RedHat 6.1 appear to conflict with gcc-2.96 and are not relocatable, so they cannot be installed in e.g. /usr/local. So instead each user needing one of these compilers has to download the source, realize that they need the patch, apply the patch, and get the compilation to work. If we just had /usr/local or relocatable RPMs for 2.95.2 or egcs-1.1.2 we could avoid all of that hassle, and perhaps RedHat wouldn't be getting flamed so much about GCC :-). |
This bug report applies both to GCC 2.96 as shipped with RH 7.0 and to the updated 2.96-69 release. I download a 2.95.2 tarball, and build it as follows: % ./configure --enable-shared --enable-version-specific-runtime-libs % make bootstrap It builds for a while, until I get: indstream.cc: In method `struct streampos indirectbuf::seekoff(long long int, ios::seek_dir, int = 3)': indstream.cc:82: `struct streampos' used where a `int' was expected indstream.cc:85: `struct streampos' used where a `int' was expected indstream.cc:87: `struct streampos' used where a `int' was expected indstream.cc:89: conversion from `int' to non-scalar type `streampos' requested indstream.cc: In method `struct streampos indirectbuf::seekpos(_G_fpos64_t, int = 3)': indstream.cc:99: `struct streampos' used where a `int' was expected indstream.cc:102: `struct streampos' used where a `int' was expected indstream.cc:104: `struct streampos' used where a `int' was expected indstream.cc:106: conversion from `int' to non-scalar type `streampos' requestedmake[2]: *** [indstream.o] Error 1 make[1]: *** [all-target-libio] Error 2 make: *** [bootstrap] Error 2 This problem is a double whammy for my company becuase: 1) The same behavior of 2.96 shows up when I try to build my companies code. 2) We are successfully using GCC 2.95.2 on RedHat 6.2 but cannot recreate this success in RedHat 7.0 because we cannot build the compiler. Consequently we are unable to move to RedHat 7.0 as a development platform.
