After 00e13e30a2 it's no longer possible to use libphoton.a

[Alexander Medvednikov]

Particularly after this change:

00e13e3#diff-1e7de1ae2d059d21e1dd75d5812d5a34b0222cef273b7c3a2af62eb747f9d20aL302-R313

For the V language we generate photonwrapper.so using these 2 build commands:

https://github.com/vlang/photonbin/blob/master/build.sh

It used to work fine.

Now we have to do a patch:

https://github.com/vlang/photonbin/blob/master/macos_photonlib_patch.txt

Hopefully this can be fixed. Thanks!

Does it only happen in macOS?

[Bob Chen]

The libphoton.a in the latest release has included all the third-party libs, except libssl and libcurl.

So basically you just need this achieve file alone.

[Alexander Medvednikov]

We've only tested on macos so far, will do Linux today.

[Bob Chen]

Please try the latest Photon release, and build a new libphoton.a.

ld: archive member 'libphoton_sole.' not a mach-o file in '/dev/src/cpp/PhotonLibOS/output/libphoton.a'

[Bob Chen]

How did you build photon? Can I see your build command?

[Alexander Medvednikov]

By running

/Users/alex/code/3rd/PhotonLibOS $ cmake .
/Users/alex/code/3rd/PhotonLibOS $ make

That generates build/output/libphoton.a

and we get the not a mach-o file error when running

[Bob Chen]

It seems the ar in macOS is quite different than the one in Linux. Perhaps I need to try the libtool tool

build/output/libphoton.dylib is correct

[Bob Chen]

Hopefully this patch would fix. #195

[Alexander Medvednikov]

Yes, it did. Great job!

Thanks.
