A \fIdependency-template\fR is a +dependency where \fI#MINVER#\fR is dynamically replaced either by +a version check like “(>= \fIminimal-version\fR)” or by nothing (if +an unversioned dependency is deemed sufficient). +.P +Each exported \fIsymbol\fR (listed as \fIname\fR@\fIversion\fR, with +\fIversion\fR being “Base” if the library is not versioned) is associated +to a \fIminimal-version\fR of its dependency template (the main dependency +template is always used and will end up being combined with the dependency +template referenced by \fIid-of-dependency-template\fR if present). The +first alternative dependency template is numbered 1, the second one 2, +etc. +.P +Each entry for a library can also have some fields of meta-information. +Those fields are stored on lines starting with an asterisk. Currently, +the only valid fields are: +.TP +.B Build\-Depends\-Package +It indicates the name of the “\-dev” package associated to the library +and is used by \fBdpkg\-shlibdeps\fP to make sure that the dependency +generated is at least as strict as the corresponding build dependency +(since dpkg 1.14.13). +.TP +.B Ignore\-Blacklist\-Groups +It indicates what blacklist groups should be ignored, as a whitespace +separated list, so that the symbols contained in those groups get +included in the output file (since dpkg 1.17.6). +This should only be necessary for toolchain +packages providing those blacklisted symbols. The available groups are +system dependent, for ELF and GNU-based systems these are \fBaeabi\fP +and \fBgomp\fP. +.SH EXAMPLES +.SS Simple symbols file +.PP +libftp.so.3 libftp3 #MINVER# + DefaultNetbuf@Base 3.1-1-6 + FtpAccess@Base 3.1-1-6 + [...] +.SS Advanced symbols file +.PP +libGL.so.1 libgl1 +.br +| libgl1\-mesa\-glx #MINVER# +.br +* Build\-Depends\-Package: libgl1\-mesa\-dev + publicGlSymbol@Base 6.3-1 + [...] + implementationSpecificSymbol@Base 6.5.2-7 1 + [...] +.SH SEE ALSO +.BR https://wiki.debian.org/Projects/ImprovedDpkgShlibdeps +.br +.BR dpkg\-shlibdeps (1), +.BR dpkg\-gensymbols (1). -- cgit v1.2.3
