Building Zlib module fails
bspaulding opened this issue · comments
Sorry if this is totally the wrong place for this issue, but I am a bit out of my depth. :/
Trying to add maxpng to a swift project, and compile on mac os, I am getting some compile errors related to zlib.
Running macOS 10.13, Xcode 9.0.1
Output:

i believe this was fixed in master, see this pr,, can you test with the current branch? i don’t think the fix has been tagged in a release
Thanks @Kelvin13 that does indeed fix it in master, do you mind pushing a version tag so we can use that without manually checking out and using a 'path' dependency? Appreciate your efforts :)
master is currently a development repository for the 3.0 version of the library, which has not been released, mainly for missing documentation. I would recommend just setting your SPM dependency to trunk instead of a version tag for now.
issue is no longer relevant, as zlib dependency was removed in 4.0.0
