Replace step 2 with: gcc296 -I /usr/lib/i386-redhat-linux7/include \ -B /usr/lib/i386-redhat-linux7/lib/ -O3 -o no_rh7 no_rh7.c That works for me. (If this doesn't work for you, make sure you have the compat-glibc package installed.) I have been running Fedora Core 2 since submitting this bug report, but still observe the same behavior as reported. Sorry, but as far as I can tell there is no such package as "compat-glibc" available for Fedora Core 2. Executing "apt-cache search compat", I see only the following related packages: compat-gcc compat-gcc-c++ compat-gcc-g77 compat-gcc-java compat-gcc-objc compat-libgcj compat-libgcj-devel compat-libstdc++ compat-libstdc++-devel Perhaps you could clarify what you mean by the "compat-glibc" pacakge. I was under the impression that compat-gcc included a backward-compatible libc. Ok, that's a whole different issue -- there's a compat-glibc package for RHEL 3, but not for Fedora Core 2. Here's the URL for the compat-glibc package from Tao Linux (a RHEL clone). You can try it and see if it works on FC2: http://dist.taolinux.org/tao-1.0-i386/RPMS.os/compat-glibc-7.x-2.2.4.32.5.i386.rpm As far as I understand: compat-gcc does not include any kind of libc. The development headers, etc. for the old glibc are in the compat-glibc package. Backward compatibility for old binaries is included in the current glibc (that is, there are no separate packages for that functionality). Does that clear things up? compat-glibc is not going to be provided in FC, I don't see the demand for it. If you want to build apps for an older system, just use that older system. If so, what is the idea of keeping other compat-* packages in FC? Sometimes people need to be able to build older software on newer distributions using older compilers. That's the usefulness of compat-gcc IMO. I don't know enough about the other compat-* packages however. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040211 Firefox/0.8 Description of problem: According to the description of compat-gcc: This package includes a compiler that can be to generate binaries that will run on older Red Hat Linux systems (namely Red Hat Linux 7.3). This package includes the C compiler and required compiler libraries for those systems. Despite this, application compiled using compat-gcc will not run on RH7.3 in general. Nor are RH7.3-compatible libraries included in the compat-gcc RPM. The "compatible" compiler still links against glibc-2.3, which is not present on RH7.3. Version-Release number of selected component (if applicable): compat-gcc-7.3-2.96.118 How reproducible: Always Steps to Reproduce: 1. Create a file, no_rh7.c, containing the following text: #include <ctype.h> main () { int t = tolower ('T'); printf ("%chis works!\n", t); } 2. Compile the file as follows: gcc296 -O3 -o no_rh7 no_rh7.c 3. Execute this command to see that the binary is linked against glibc-2.3: nm no_rh7 | grep GLIBC_2.3 4. Try to run this binary on RH7.3 to see it fail. Actual Results: Executable will not run on RH7.3, because it is linked against glibc-2.3. Expected Results: Executable should run on RH7.3 (should not be linked against glibc-2.3). Additional info:
