From 21b3c4962055f4b7ba6be6af9347db6e0f750b76 Mon Sep 17 00:00:00 2001 From: Guillem Jover Date: Tue, 16 Sep 2025 23:21:09 +0200 Subject: [PATCH] Fix SONAME filename handling The shared library should be installed as its SONAME, because the package that provides it also ships the shlibs metadata file. Otherwise dpkg-shlibdeps cannot find the mapping between the SONAME used by other objects with the package containing the shlibs file. This problem has been shadowed on users with merged-/usr with aliased directories because the dpkg-shlibdeps code was failing to locate the library under /lib (instead of the canonical location under /usr/lib) and was then using a fallback code path where it would canonicalize the filename, and would then find the actual shared library in the libgctp-2.0.0 package and then be able to find the shlibs file (instead of trying to look into the libgctp-dev package). On systems with merged-/usr with aliased filenames or once the /lib directory gets removed from the ld.so.conf pathnames, then dpkg-shlibdeps is unable to find the shlibs file. Although shipping a .so filename in a non-dev package is unconventional, this is the expected thing to do with shared libraries with SONAME denoting an unstable interface (like lib-.so). A similar example would be libbinutils. Ideally upstream would switch from using -release to -version-info in the build-system (but that's going to be an ABI break, and upstream does not look very active). --- debian/control | 3 ++- debian/libgctp-2.0.0.install | 2 +- debian/libgctp-2.0.0.links | 3 ++- debian/libgctp-dev.links | 3 +-- debian/rules | 1 - 5 files changed, 6 insertions(+), 6 deletions(-) diff --git a/debian/control b/debian/control index d2c3aca..cfa1f3c 100644 --- a/debian/control +++ b/debian/control @@ -14,7 +14,8 @@ Package: libgctp-2.0.0 Section: libs Architecture: any Multi-Arch: same -Breaks: libgctp-dev (<< 2.0.0-9) +Breaks: libgctp-dev (<< 2.0.0-13~) +Replaces: libgctp-dev (<< 2.0.0-13~) Depends: ${shlibs:Depends}, ${misc:Depends} Description: General Cartographic Transformation Package Library The General Cartographic Transformation Package (GCTP) is a system of diff --git a/debian/libgctp-2.0.0.install b/debian/libgctp-2.0.0.install index 5eaf89a..5e8fd16 100644 --- a/debian/libgctp-2.0.0.install +++ b/debian/libgctp-2.0.0.install @@ -1 +1 @@ -/usr/lib/${DEB_HOST_MULTIARCH}/libgctp-2.so.2.0.0 +/usr/lib/${DEB_HOST_MULTIARCH}/libgctp-2.0.0.so diff --git a/debian/libgctp-2.0.0.links b/debian/libgctp-2.0.0.links index dd33a8e..3972f00 100644 --- a/debian/libgctp-2.0.0.links +++ b/debian/libgctp-2.0.0.links @@ -1 +1,2 @@ -/usr/lib/${DEB_HOST_MULTIARCH}/libgctp-2.so.2.0.0 /usr/lib/${DEB_HOST_MULTIARCH}/libgctp-2.0.0.so.2 +/usr/lib/${DEB_HOST_MULTIARCH}/libgctp-2.0.0.so /usr/lib/${DEB_HOST_MULTIARCH}/libgctp-2.0.0.so.2 +/usr/lib/${DEB_HOST_MULTIARCH}/libgctp-2.0.0.so /usr/lib/${DEB_HOST_MULTIARCH}/libgctp-2.so.2.0.0 diff --git a/debian/libgctp-dev.links b/debian/libgctp-dev.links index cec3ceb..2e227f2 100644 --- a/debian/libgctp-dev.links +++ b/debian/libgctp-dev.links @@ -1,2 +1 @@ -/usr/lib/${DEB_HOST_MULTIARCH}//libgctp-2.so.2.0.0 /usr/lib/${DEB_HOST_MULTIARCH}/libgctp-2.0.0.so -/usr/lib/${DEB_HOST_MULTIARCH}//libgctp-2.so.2.0.0 /usr/lib/${DEB_HOST_MULTIARCH}/libgctp.so +/usr/lib/${DEB_HOST_MULTIARCH}//libgctp-2.0.0.so /usr/lib/${DEB_HOST_MULTIARCH}/libgctp.so diff --git a/debian/rules b/debian/rules index 2458a3b..6b43de7 100755 --- a/debian/rules +++ b/debian/rules @@ -32,5 +32,4 @@ override_dh_auto_install: dh_auto_install -- 'CC=$(CC)' rm $(INSTDIR)/libgctp.la $(INSTDIR)/libgctp.so mv $(INSTDIR)/libgctp.a $(INSTDIR)/libgctp2.a - mv $(INSTDIR)/libgctp-2.0.0.so $(INSTDIR)/libgctp-2.so.2.0.0 -- 2.51.0
