How do I mix shared and static libs

[Phil67ago]

Following failed on '-lshared-lib' because it is a shared lib only.
The rest ( '-lcrypto', '-lssl') is okay because they exist as static and shared libs.
On meson 0.59 how do I mix shared and static libs?
'-static' makes it static.

project('foo', 'cpp')

project_sources = []
project_includes = [ include_directories('include/','src/') ]
project_c_args = [ '-ffunction-sections', '-fPIC' ]
project_link_args = ['-static', '-Wl,-gc-sections' , '-lshared-lib', '-lcrypto', '-lssl' ]
subdir('src')

exe=executable( 'foo',
project_sources,
include_directories : [ project_includes ],
c_args : project_c_args,
link_args : project_link_args,
)

This isn't something Meson is doing. The -static compiler option says to the compiler that only static libraries are allowed. As a result, the compiler fails when static libraries aren't available.

That option also says to statically link to the platform C standard library (e.g. glibc).

What's your goal here? If you just want to link some of your dependencies statically, but you don't want to build a "fully static" executable, don't use the -static compiler option.

You're also manually using -l flags for libraries, but Meson doesn't like it when you do this. Instead you should use dependency('openssl') or dependency('libssl') or dependency('libcrypto') (depending on which parts of the OpenSSL project you need to link to) and Meson will figure out the best way to link to it.

This allows you to pass the static: true kwarg to the dependency lookup, which forces Meson to detect the ssl/crypto libraries as static libraries only.

Meanwhile cc.find_library('shared-lib') will find that other library and allow either static or shared (probably shared) versions.

Tested and yes that seems to work!
/Thanks

project('foo', 'cpp')

project_sources = []
project_includes = [ include_directories('include/','src/') ]
project_c_args = [ '-ffunction-sections', '-Os', '-fPIC' ]
project_link_args = [ '-Wl,-gc-sections' ]
project_dep = [ dependency('shared-lib'), dependency('crypto'), dependency('ssl',static:true) ]
subdir('src')

exe=executable( 'foo',
project_sources,
include_directories : [ project_includes ],
c_args : project_c_args,
dependency : project_dep
link_args : project_link_args,
)

Great, happy to help.

Note there are some other optimizations you can do. Instead of passing '-Os' you can use project(..., default_options: ['optimization=s']) and I'm pretty sure -fPIC is the default already.

The advantage of using default_options is that users can override it if they really want, and either way Meson will handle the option correctly across different compilers.
