Hello, sparse is a C code checker that reuses include files from gcc. Currently there are missing the needed dependencies (https://bugs.debian.org/906472). Now I wonder, what is the right way to depend on gcc. For sparse it would be enough to depend on libgcc-8-dev (I think), but as cgcc (which is included in the sparse package) calls gcc, too, I need a dependency on the gcc package directly (which via gcc-8 depends on libgcc-8-dev). As gcc-7 doesn't provide the needed paths, gcc 4:7.whatever isn't enough though. I can imagine the following options to depend on: a) gcc, libgcc-8-dev b) gcc (>= 4:8~), gcc (<< 4:9) . Both have the disadvantage that they need manual adaption when gcc bumps it's major version. a) also has the disadvantage that gcc might provide gcc-9 and so sparse uses different includes than the default compiler (not sure this is bad enough to care). b) is bad, because gcc_4:9~prerelease12 would be good enough to make dpkg happy, but sparse would fail anyhow. Alternatively sparse could stop hardcoding the include path and ask gcc on each invokation. But I don't like that much as the path hardly ever changes and it adds some overhead to sparse. Do you have any thoughts/recommendations? Best regards Uwe
