Package: libc6 Version: 2.3.6.ds1-7 Severity: normal (Not sure if this is a bug in libc6 or binutils or another package; I first thought it was a bug in gcc, but a gcc developer said no: <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29588>.)
gcc has /usr/local/include in its default search path, i.e. without setting any special environment variable. Therefore, in order to be consistent, the linker should have /usr/local/lib is its search path too, *by default*. Here's a way to reproduce the problem (just an example): 0. Make sure you have default *PATH settings (i.e. no C_INCLUDE_PATH, no LIBRARY_PATH, no LD_LIBRARY_PATH set to some value). 1. Install the official GMP packages, so that one has GMP 4.2.1 files installed in /usr/include and /usr/lib directories. 2. Download GMP 4.2.1 and replace the __GNU_MP_VERSION_PATCHLEVEL value, e.g. by 17. 3. Build and install GMP 4.2.17 with configure, make, make install (install-nodist_includeexecHEADERS and install-libLTLIBRARIES are sufficient). 4. Compile the following program with either: gcc -Wall gmpversion.c -o gmpversion -lgmp or gcc -Wall -static gmpversion.c -o gmpversion -lgmp #include <stdio.h> #include <gmp.h> int main (void) { printf ("GMP ..... Library: %-6s - Header: %d.%d.%d\n", gmp_version, __GNU_MP_VERSION, __GNU_MP_VERSION_MINOR, __GNU_MP_VERSION_PATCHLEVEL); return 0; } 5. Run it. You should get: GMP ..... Library: 4.2.1 - Header: 4.2.17 This is an incorrect behavior. With default settings, one should get the same header and library versions (whether this is 4.2.1 or 4.2.17, I don't care, this is just a policy matter). A solution could be: add /usr/local/lib to /etc/ld.so.conf by default. I've not tried, though. I hope this fixes the behavior with libtool too. But I don't know about the -static option (perhaps a bug in ld, thus in the binutils package?). Note: because of this problem, we get bug reports for our software because of inconsistent header and library versions. This is a problem with GMP in particular as GMP 4.1.4 (from Debian/stable) and GMP 4.2.1 are incompatible. -- System Information: Debian Release: testing/unstable APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.18-1-686-bigmem Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.ISO8859-1 (charmap=ISO-8859-1) Versions of packages libc6 depends on: ii tzdata 2006n-1 Time Zone and Daylight Saving Time libc6 recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
