I had to read this thread several times before I caught onto the context of your question. If I restate your question a bit for the more general case: I have an application which should link statically against one (or more) specific library(ies) and dynamically against the rest of the external libraries... Then the general case answer is: You have to make two link(er) passes; The first to produce a "partial link" output that is your application linked against the selected static library(ies); The second to complete the linkage using the dynamic library(ies). The general case answer when using a GCC/Binutils toolchain: For many situations you can emulate multiple linker passes by using the --start-group <archives> --end-group pair of option quotes. From the gcc command line: -Wl,--start-group <archives> -Wl,--end-group There is a short form of that option pair: -( archives )- Where: "archives" may be a list of object files also. So if Binutils linker (or GCC linker) command included only static library(ies) within the group, then the linker would make repeated passes over that group until no new undefined symbols where generated. In this case, by statically linking in the specified archive(s). ;-) Your more specific question: How to get the OpenSSL Makefile to recognize: zlib-static (or zlib as static)? If using GCC/Binutils toolchain, then answering that one is a matter of either reading the Makefile(s) or waiting for an author of the Makefile(s) to take note of this thread and tell us. The thing(s) to look for would be either a Makefile that produces more than one linker run over the object files or that uses the grouping quotes (or both). If using any other toolchain, I don't have the slightest clue.
