Some more thoughts: - if the linkage of the mymain with libpthread is not required, why g++-4.5 requires it ? => it would be a bug in g++-4.5 - if the linkage is required, then this means that the linkage of a library is part of its ABI. Ie, the soname of a library A must change when the list of libraries (B, C, ...) that A links with changes, even if no types or symbols of libraries B, C, ... are exported by the library A. => dh_makeshlibs/dh_shlibdeps should be adapted > > Regards, > Vincent -- Vincent Danjean GPG key ID 0x9D025E87 vdanj...@debian.org GPG key fingerprint: FC95 08A6 854D DB48 4B9A 8A94 0BF7 7867 9D02 5E87 Unofficial packages: http://moais.imag.fr/membres/vincent.danjean/deb.html APT repo: deb http://perso.debian.org/~vdanjean/debian unstable main -- To UNSUBSCRIBE, email to debian-gcc-requ...@lists.debian.org with a subject of "unsubscribe".
